Strategic Management Strengthens Sustainable Educational Tourism Schools and Student Environmental Entrepreneurship
type: item
description: Educational tourism programs embedded in schools are increasingly promoted to deliver experiential learning, yet many institutions struggle to sustain them amid limited resources, uneven stakeholder commitment, and weak strategic alignment. This study aims to explain how strategic management practices enable sustainable educational tourism schools while strengthening student character education and environmental entrepreneurship. Using a qualitative multiple-case design, data were collected in two junior high schools implementing educational tourism initiatives through semi-structured interviews with school leaders, teachers, students, parents, and program teams, complemented by onsite observations and document analysis. Thematic analysis indicates that program sustainability is achieved through a participatory strategic management cycle that integrates vision-driven planning, structured implementation with clear task allocation, and periodic evaluation used for continuous adjustment. Empirically, the programs improve students’ environmental literacy, creativity, responsibility, and entrepreneurial orientation through hands-on activities such as eco-farming, waste-to-resource practices, and student-managed production units. A key novelty of this study is its comparative, end-to-end mapping of strategic management processes across two educational tourism school models, demonstrating how adaptive evaluation and stakeholder collaboration jointly compensate for constraints in funding and human resources. The findings advance theory by linking strategic management cycles to experiential character learning outcomes, and they inform policy and practice by recommending stronger cross-sector partnerships, capacity development for teachers and students, and data-informed monitoring to institutionalize sustainable educational tourism in secondary education. Highlights: Participatory strategic management offsets resource constraints through multi-stakeholder collaboration. Cont…

The Validity of Imam Shafi‘i, Criticism, and the Influence of Yahya Bin Ma’in's Accusations on the Weakness of Transmission in Hadith Chains
type: item
description: General Background: Imam Shafi‘i is widely recognized as a leading mujtahid and a major authority in Islamic jurisprudence and hadith scholarship, whose narrations have long been referenced in classical Islamic sciences. Specific Background: Despite this recognition, certain criticisms—most notably attributed to Yahya bin Ma‘in—questioned Imam Shafi‘i’s reliability as a hadith transmitter, particularly regarding sanad assessment within the tradition of jarh wa ta‘dil. Knowledge Gap: These accusations have often been cited without systematic evaluation against broader scholarly consensus and established methodological principles of hadith criticism. Aims: This study aims to reassess Yahya bin Ma‘in’s accusations and examine their standing within jarh wa ta‘dil, focusing on whether they undermine Imam Shafi‘i’s status as a thiqah narrator. Results: Based on qualitative library research and comparative analysis of classical sources, the study finds that the accusations lack substantiated grounds, are contradicted by other authenticated statements from Yahya bin Ma‘in himself, and are outweighed by extensive scholarly endorsement of Imam Shafi‘i’s reliability. Novelty: The article provides a structured clarification that situates isolated criticism within the wider epistemological framework of hadith sciences, emphasizing scholarly consensus and narrator reputation. Implications: These findings reaffirm Imam Shafi‘i’s authority in hadith transmission and offer a methodological reference for addressing contested evaluations of narrators in Islamic scholarship. Highlights: Accusations against Imam Shafi‘i lack methodological consistency when examined through classical hadith principles. Scholarly consensus affirms his status as a trustworthy narrator despite isolated critiques. Omission from certain canonical compilations does not constitute evidence of unreliability. Keywords: Imam Shafi‘I, Hadith Transmission, Jarh wa Ta‘dil, Sanad Criticism, Yahya bin Ma‘in

Integration of Psychology and Islamic Education in Internalizing Exemplary Values through Historical Figures of Islam
type: item
description: General Background: Islamic education aspires to develop learners’ character alongside knowledge through the internalization of divine values. Specific Background: In History of Islamic Culture learning, Islamic historical figures are often taught as biographical content and chronology rather than as lived moral exemplars, contributing to a gap between cognitive knowledge and noble conduct. Knowledge Gap: A conceptual framework is needed that unites educational psychology with Islamic educational concepts to explain both the learning mechanisms and the spiritual orientation of exemplary learning. Aims: This article formulates an integrative conceptual model between psychology and Islamic education to support exemplary value internalization through Islamic historical figures. Results: Using library research and descriptive-analytical synthesis, the study proposes a three-stage framework: a cognitive stage combining information processing theory with tadabbur for deep understanding; an affective stage aligning humanistic empathy with tazkiyatun nafs to build emotional attachment; and a conative/behavioral stage integrating shaping and reinforcement with ittibaʾ to realize values in concrete actions. Novelty: The framework synthesizes psychological stages of learning with Islamic spiritual concepts into a holistic pathway that shifts Islamic Cultural History from knowledge transfer to value-oriented character formation. Implications: The model calls for teachers as facilitators and living role models, participative-reflective methods, and authentic, holistic assessment of learners’ value-oriented behavior. Highlights: A triadic pathway connects information processing with tadabbur to deepen understanding of historical narratives. Empathic learning conditions are paired with tazkiyatun nafs to cultivate emotional attachment and reflective practice. Shaping and reinforcement are linked with ittibaʾ to translate moral lessons into sustained daily actions and authentic ass…

Reducing Academic Stress through Autonomy Fulfillment: A Self Determination Theory Solution in the Context of Students' Cognitive Load
type: item
description: General Background Academic stress has emerged as a critical issue in contemporary education, with increasing learning demands and structural pressures contributing to students’ psychological strain. Specific Background Cognitive Load Theory explains that excessive academic demands, arising from material complexity, task accumulation, and inefficient instructional design, exceed students’ working memory capacity and intensify stress, while educational policies and curriculum structures at the exosystem level further reinforce this burden. Knowledge Gap Existing studies predominantly examine academic stress through isolated internal or external factors, with limited integration of cognitive load, exosystem structures, and autonomy within a unified analytical framework. Aims This study aims to explain the role of cognitive load in the emergence of academic stress, analyze exosystem factors that exacerbate learning burden, and evaluate autonomy fulfillment within Self-Determination Theory as a strategy for reducing academic pressure. Results The findings indicate that excessive cognitive load significantly contributes to academic stress, while dense curricula, rigid schedules, and assessment policies intensify this condition; autonomy-supportive learning environments reduce extraneous cognitive load and strengthen students’ self-regulation in managing academic demands. Novelty This study integrates Cognitive Load Theory, Bronfenbrenner’s ecological perspective, and Self-Determination Theory to provide a comprehensive explanation of academic stress. Implications The findings highlight the necessity of flexible curriculum design, autonomy-supportive instructional practices, and policy reform to promote students’ mental well-being and sustainable learning environments. Highlights: Excessive learning demands and structural academic arrangements are closely associated with heightened psychological strain. Policy-level curriculum density and assessment practices contribute t…

Instilling Social Care Character in Children Aged 4–5 Years Through the IHF 9 Character Pillars Book
type: item
description: General Background Character education in early childhood is a critical foundation for developing prosocial behavior, particularly helping behavior as part of social-emotional development. Specific Background In Indonesian early childhood education settings, many children aged 4–5 years still demonstrate low initiative in sharing, cooperating, and assisting peers, partly due to the absence of structured and systematic learning media. Knowledge Gap Although the Indonesia Heritage Foundation (IHF) 9 Character Pillars Book is widely recognized in practice, empirical studies focusing on its use as a single, structured medium to instill the value of helping others remain limited. Aims This study aims to analyze the implementation process and outcomes of using the IHF 9 Character Pillars Book to cultivate helping behavior among Group A children aged 4–5 years in a formal early childhood education context. Results Using a descriptive qualitative case study approach at RA Al-Falah Tuban, the findings indicate that staged implementation of the IHF book—integrated into daily learning activities—was associated with observable improvements in children’s willingness to help, share, and participate in cooperative tasks, with the proportion of children demonstrating spontaneous helping behavior increasing from initial observations to the end of the intervention period. Novelty This study provides in-depth evidence on the use of a standardized character education book as a focused medium for instilling helping values in early childhood. Implications The findings offer a practical, structured model for teachers to integrate story-based character education into routine classroom practices, while highlighting the importance of consistency between school and home environments. Highlights: Staged classroom integration of character storybooks supported observable growth in children’s prosocial actions. Teacher-guided reflection and role play facilitated the internalization of care and co…

Obstacle in Elementary Education Classroom Management Barriers in Managing Elementary School Classrooms
type: item
description: General Background: Classroom management is central to the success of learning processes, particularly in elementary education where learners undergo social, emotional, and moral development. Specific Background: Managing classroom dynamics and sustaining student engagement are complex in primary schooling because rule recognition, peer interaction, and discipline formation are still developing. Knowledge Gap: Although classroom management strategies are widely discussed, research detailing contextual obstacles in primary education remains limited and often prioritizes solution-oriented training without sufficiently examining underlying causes of management failure. Aims: This study identifies and analyzes obstacles in elementary classroom management and formulates conceptual recommendations for a conducive, productive, and sustainable learning environment. Results: Using a descriptive qualitative library research approach, the study finds that obstacles are multidimensional, stemming from teacher-related conditions (e.g., authoritarian leadership, monotonous instruction, limited knowledge, weak teacher–student rapport), student-related conditions (e.g., inconsistent behavior, low task responsibility, rule-breaking), family environment (parenting styles shaping discipline and motivation), and learning facilities (limited space, overcrowding, inadequate learning media and tools). These conditions reduce learning quality and contribute to less conducive classroom situations. Novelty: The article consolidates a contextual, factor-based mapping of primary education classroom management obstacles and aligns them with categorized handling domains (teacher authority, school authority, and issues requiring wider stakeholder involvement). Implications: Preventive, corrective, and curative actions—supported by collaboration among teachers, schools, committees, and parents—are indicated as essential pathways for addressing obstacles and guiding policy and strategy formulation …

The Emancipatory Critical Paradigm in Islamic Religious Education as an Effort to Form a Tolerant and Multicultural Attitude
type: item
description: General Background The persistence of religious intolerance and exclusivism within educational contexts reveals unresolved pedagogical challenges in religious education systems. Specific Background In Islamic Religious Education, learning practices remain largely normative–doctrinal and transmissive, limiting students’ dialogical engagement and critical awareness within pluralistic social realities. Knowledge Gap Although tolerance and multiculturalism have been widely discussed, few studies systematically integrate a critical–emancipatory paradigm into the ontological, epistemological, and axiological foundations of Islamic Religious Education. Aims This study analyzes the relevance and conceptual contribution of the critical–emancipatory paradigm as an alternative pedagogical framework for Islamic Religious Education in fostering tolerant and multicultural attitudes. Results Using qualitative library research grounded in critical theory, the findings demonstrate that the critical–emancipatory paradigm is theologically and pedagogically compatible with Islamic values such as justice, human dignity, and rahmatan lil ‘alamin, while redirecting learning from indoctrinative models toward dialogical, reflective, and contextual practices. Novelty This article constructs an integrative conceptual framework linking the critical–emancipatory paradigm with the ontological, epistemological, and axiological dimensions of Islamic Religious Education. Implications The study contributes theoretically to critical Islamic education discourse and offers a coherent pedagogical orientation for developing tolerance, social empathy, and multicultural competencies within Indonesia’s pluralistic educational context. Highlights: Normative–doctrinal learning practices are conceptually linked to weak internalization of plural social values. Dialogical and reflective pedagogy aligns with Islamic theological principles of justice and human dignity. Ontological, epistemological, and axiological…

Relationship Analysis Economic Growth and Unemployment Rate in East Java: Okun's Curve Anomaly Before and After the COVID-19 Pandemic
type: item
description: Economic growth and unemployment rates are two macroeconomic indicators used to measure the government's success in improving the welfare of the people. Low economic growth will lead to high unemployment rates, which is in line with Okun's law. Over the past two years, East Java's economic growth has contracted but has not been accompanied by a decline in unemployment rates. This is interesting considering that reality does not align with theory. This study aims to examine the consistency of Okun's law with reality both before and after the COVID-19 pandemic. What is interesting about this study is that the COVID-19 pandemic has significantly changed the economy of East Java. This reality has actually improved the relationship between economic growth and unemployment rates. Based on Pearson's correlation coefficient, an inverse relationship was found between the pre- and post-pandemic periods. Therefore, it can be concluded that external interventions such as a pandemic can improve the relationship between the two variables to an appropriate level. The implications of these findings indicate that post-pandemic economic recovery needs to be directed towards strengthening labour-intensive sectors that absorb a large workforce. Policies to develop MSMEs, downstreaming, and improving skills after the pandemic could be the key to making East Java's economic growth more inclusive while reducing unemployment. Highlights: Tests Okun’s law consistency in East Java before and after COVID-19. Finds inverse correlation between growth and unemployment post-pandemic. Recommends post-pandemic recovery through labour-intensive and MSME sectors. Keywords: Economic Growth, Open Unemployment Rate, Okun's Curve, Pandemic, Pearson

Digital Word of Mouth, Destination Attractiveness, Brand Image, Accessibility Drive Tourist Intention
type: item
description: Tourist decision-making in competitive coastal destinations is increasingly shaped by digital exposure, experiential perceptions, and logistical convenience. This study investigates how electronic word of mouth (e-WOM), destination attractiveness, brand image, and accessibility influence tourist visiting intention at a major coastal destination in Indonesia. Using a quantitative ex post facto design, data were collected from 100 purposively selected respondents aged 18 years and above who had visited the destination at least twice and completed a validated Likert-scale survey. Multiple linear regression, supported by t-tests, F-tests, and adjusted R² analysis, reveals that e-WOM, destination attractiveness, brand image, and accessibility each exert a significant positive effect on tourist visiting intention. Collectively, these predictors explain approximately 76.6% of the variance in visiting intention, confirming that digital word of mouth, experiential quality, perceived brand reputation, and travel convenience function as integrated behavioral determinants rather than isolated stimuli. This study contributes empirical evidence to tourism behavior literature by demonstrating that destination competitiveness is strongly anchored in digital influence and multimodal experience rather than physical attraction alone. The findings indicate that enhancing the digital communication ecosystem, strengthening experiential attributes, improving brand positioning, and accelerating access infrastructure are strategic priorities for destination managers seeking to stimulate sustained tourist intention and market resilience. The study offers practical implications for tourism policy, destination marketing organizations, and stakeholders in designing targeted interventions that align with post-pandemic travel patterns and data-driven visitor expectations. Highlights • Digital word of mouth significantly strengthens tourist visiting intention. • Combined predictors explain 76.6% o…

Financial Literacy, Government Support, and Fintech Adoption as Drivers of SME Sustainability Performance
type: item
description: General Background The rapid expansion of financial technology has reshaped financial practices among Micro, Small, and Medium Enterprises in Indonesia, particularly within the context of digital economic transformation. Specific Background In Bandar Lampung City, despite government digitalization initiatives, fintech utilization among MSMEs remains uneven, with persistent reliance on manual financial systems affecting sustainability outcomes. Knowledge Gap Existing technology adoption models insufficiently explain fintech adoption by MSMEs when institutional support, financial literacy, trust, and sustainability dimensions are jointly considered in a local Indonesian setting. Aims This study examines determinants of fintech adoption and evaluates its role in shaping MSME sustainability performance across economic, social, and environmental dimensions. Results Using a quantitative survey of 200 MSMEs and SEM-PLS analysis, financial literacy, government support, trust, perceived usefulness, and perceived ease of use were found to significantly shape fintech adoption, while user innovation showed no direct relationship. Fintech adoption demonstrated a strong association with sustainability performance. Novelty This study integrates Technology Acceptance Model constructs with institutional and sustainability perspectives to explain fintech adoption mechanisms in regional MSMEs. Implications The findings highlight the importance of coordinated government policies and financial literacy initiatives in fostering fintech-driven sustainability among MSMEs within emerging digital economies. Highlights: Multiple internal and institutional factors jointly explain digital financial system usage among small businesses. Digital financial system usage aligns with economic, social, and environmental business outcomes. Individual innovativeness alone does not translate into technology usage without supporting conditions. Keywords: Fintech, Financial Literacy, Government Support, Use…

The Impact of Corporate Social Responsibility Disclosure, Profitability, Leverage, Liquidity, and Sales Growth on Firm Value
type: item
description: General Background Firm value represents a key market-based indicator reflecting investor assessment of corporate performance and future prospects in capital markets. Specific Background In Indonesia, rapid growth of the capital market and sectoral expansion in industrials, consumer non-cyclical, and healthcare companies have intensified attention toward financial and non-financial disclosures associated with firm value. Knowledge Gap Prior empirical findings on the roles of corporate social responsibility disclosure, profitability, leverage, liquidity, and sales growth in shaping firm value remain inconsistent, particularly across specific IDX sectors and recent observation periods. Aims This study aims to examine the relationships between CSR disclosure, profitability, leverage, liquidity, and sales growth with firm value among companies listed on the Indonesia Stock Exchange during 2022–2024. Results Using 90 firm-year observations and multiple linear regression, the findings indicate that profitability shows a positive and significant association with firm value, while liquidity exhibits a negative and significant association; CSR disclosure, leverage, and sales growth demonstrate no significant relationships. Novelty This study provides recent sector-focused evidence highlighting the contrasting roles of profitability and liquidity within Indonesian listed firms during the post-pandemic period. Implications The results suggest that investors prioritize profit-generating capability over CSR disclosure and growth indicators, while excessive liquidity may signal inefficient resource allocation, offering insights for corporate financial management, investors, and regulators concerned with firm value formation. Highlights: Profit-generating capacity emerged as the strongest statistically supported driver of market valuation. Excessive short-term asset holdings were associated with lower market appraisal. Sustainability reporting and revenue expansion indicators were…

Value Chain and Digital Pathways for South Nias Robusta Coffee
type: item
description: General Background Coffee is a strategic plantation commodity in Indonesia, where regional differentiation and value distribution along the chain determine competitiveness and income capture. Specific Background South Nias Regency possesses favorable agro-climatic conditions for Robusta coffee, yet production, post-harvest handling, and market access remain traditional and weakly documented, resulting in limited recognition as a local commodity. Knowledge Gap Previous studies have largely examined value chain development, digital marketing, or creative economy approaches separately and have focused on established Indonesian coffee origins, leaving emerging regions such as South Nias under-researched within an integrated analytical framework. Aims This study aims to analyze the Ulunoyo South Nias Robusta coffee chain by integrating value chain analysis with consumer evidence and a practical digital marketing roadmap. Results Using a mixed-methods design, the findings show a short, domestically oriented chain dominated by smallholders and a single collector, notable farm–collector price spreads, basic post-harvest practices, and consumer demand concentrated on powder products with a majority willing to pay for premium attributes, particularly taste and origin. Governance patterns indicate market-type coordination with captive features. Novelty The study presents a sequenced, evidence-based pathway that simultaneously links farm practices, mid-chain coordination, and end-market behavior for an under-researched coffee origin. Implications The results suggest actionable upgrading tracks encompassing process standardization, functional movement into roasting and branding, and channel development through minimal digital tools, providing a locally feasible model for strengthening South Nias Robusta coffee within local and national markets. Highlights: Monetary value concentration occurs beyond the farm gate within a short domestic trading structure. Consumer demand prioriti…

The Relationship between Sustainability Reports, Firm Size, and Company Value: The Moderating Role of Profitability in Oil and Gas Issuers Listed on the Indonesia Stock Exchange from 2019 to 2023
type: item
description: General Background: The oil and gas sector in Indonesia holds a strategic economic role while simultaneously facing increasing environmental, social, and governance demands from regulators and investors. Specific Background: Listed oil and gas companies are required to disclose sustainability reports alongside maintaining financial performance amid commodity price volatility during the 2019–2023 period. Knowledge Gap: Prior empirical studies report inconsistent findings regarding the relationships between sustainability reporting, firm size, and firm value, as well as the moderating role of profitability, particularly within capital-intensive and environmentally sensitive sectors. Aims: This study examines the relationships between sustainability reporting and firm size with firm value, and analyzes profitability as a moderating variable among oil and gas companies listed on the Indonesia Stock Exchange. Results: Using panel data regression on 50 firm-year observations, the findings show that sustainability reporting and firm size are positively and significantly associated with firm value. Profitability demonstrates a direct positive association with firm value and moderates the relationships between sustainability reporting and firm size with firm value. Novelty: The study extends prior research by integrating firm size as an explanatory variable and profitability as a moderating factor within the specific context of Indonesian oil and gas listed firms over a recent multi-year period. Implications: The results highlight the relevance of sustainability disclosure, corporate scale, and financial performance in shaping market valuation, offering insights for corporate management, investors, and policymakers concerned with sustainable corporate strategies in the oil and gas industry. Highlights: Sustainability disclosure shows a significant positive association with corporate valuation. Corporate scale demonstrates a statistically significant relationship with market-…

Power Relations, Investment Prospects, and Social Responsibility in Corporate Tax Avoidance Practices of Energy Companies in Indonesia 2020-2024
type: item
description: General Background: Corporate tax avoidance remains a critical issue when tax revenue contributions are considered suboptimal, particularly in sectors characterized by volatility. Specific Background: In Indonesia’s energy sector, recurring concerns about tax planning practices have motivated renewed empirical attention to governance- and disclosure-related determinants. Knowledge Gap: Prior studies report inconsistent conclusions regarding the relationship between politically affiliated corporate structures, investment opportunity conditions, and corporate social responsibility disclosure in relation to tax avoidance. Aims: This study examines these relationships in energy sector companies listed on the Indonesia Stock Exchange over 2020–2024 using panel data from annual and sustainability reports and estimation with a Random Effect Model in EViews. Results: Based on 41 firms (164 firm-year observations), political connections are statistically non-significant, while investment opportunities (market-to-book value) and corporate social responsibility disclosure (GRI-based index) are each negatively and significantly associated with tax avoidance as measured by the gap between the corporate income tax rate and GAAP effective tax rate; the adjusted R-squared is 0.0481. Novelty: The study consolidates political affiliation, investment opportunity conditions, and GRI-based CSR disclosure within a single energy-sector panel for Indonesia during 2020–2024. Implications: The findings suggest that stronger market-oriented growth prospects and higher CSR disclosure coincide with lower levels of tax avoidance indicators in listed energy firms, while political affiliation presence alone does not provide a statistically reliable explanation within the tested model. Highlights: Board-level political affiliation shows non-significance in the panel regression results. Higher market-to-book value corresponds to a smaller statutory-rate versus GAAP-ETR gap. Greater GRI-based sustain…

Store Atmosphere Dominates Impulse Buying in Modern Retail
type: item
description: General Background Modern retail competition increasingly emphasizes in-store factors that shape consumer purchasing behavior, particularly unplanned purchases. Specific Background Within the Indonesian modern retail context, Miniso at Tunjungan Plaza Surabaya represents a physical retail setting where product quality, product display, and store atmosphere are deliberately managed to attract consumers. Knowledge Gap Prior studies frequently examine these variables separately or in different retail contexts, leaving limited integrated empirical evidence within a single modern retail model. Aims This study aims to analyze the relationships between product quality, product display, and store atmosphere with impulse buying among Miniso consumers at Tunjungan Plaza Surabaya, both partially and simultaneously. Results Using a quantitative associative design and multiple linear regression analysis of 100 respondents, the findings show that product quality, product display, and store atmosphere are all positively and significantly associated with impulse buying, with store atmosphere demonstrating the strongest contribution. Novelty The study offers an integrated examination of three key retail stimuli within one analytical model applied to a modern specialty retailer in a high-traffic shopping mall. Implications These findings suggest that coordinated management of product attributes, visual merchandising, and physical store environment is central to understanding impulse buying behavior in modern retail settings. Highlights: Physical retail environment shows the strongest statistical contribution to unplanned purchasing behavior. Visual merchandising and merchandise attributes jointly relate to spontaneous consumer decisions. An integrated retail stimulus model explains a substantial proportion of purchasing variability.

Audit Findings, Follow-Up, and Financial Reporting Quality Fail to Reduce Corruption
type: item
description: General Background Corruption in public sector institutions remains a persistent governance challenge in Indonesia despite extensive external audit mechanisms. Specific Background The Supreme Audit Agency conducts audits of ministries and institutions, producing audit findings and follow-up recommendations intended to strengthen accountability and transparency through financial reporting. Knowledge Gap Prior empirical studies report inconsistent evidence on whether audit findings and follow-up actions are associated with corruption, particularly when financial reporting quality is positioned as a mediating mechanism. Aims This study examines the direct and indirect relationships between audit findings, follow-up on audit results, and corruption, with financial reporting quality as an intervening variable, within the framework of agency theory. Results Using panel data from 132 ministry and institutional observations during 2021–2023, the findings show that audit findings are negatively associated with financial reporting quality, while audit follow-up is positively associated with financial reporting quality. However, audit findings, audit follow-up, and financial reporting quality show no significant direct relationship with corruption, and financial reporting quality does not mediate these relationships. Novelty This study provides rare empirical evidence that financial reporting quality does not transmit the role of audit mechanisms into corruption control within Indonesian ministries and institutions. Implications The results indicate that audit processes and reporting improvements primarily function as administrative accountability tools and are insufficient as standalone instruments for addressing corruption in the public sector. Highlights: Audit observations are associated with lower standards of governmental financial statements. Recommendation completion is linked to improved compliance with accounting standards. Reporting mechanisms do not explain variati…

Regional Head Policy Implementation for Batik Artisan Economic Empowerment
type: item
description: General Background: The batik industry is a major creative economy subsector that supports cultural preservation and local economic development, yet it faces constraints related to policy limitations, technological innovation, and market expansion. Specific Background: This study examines the implementation outcomes of regional head policies for batik industry advancement as a strategy for empowering artisans in Sleman Regency. Knowledge Gap: Prior batik-related studies commonly rely on descriptive or regression approaches, providing limited insight into complex interdependence among variables linking policy, implementation, and empowerment. Aims: Using MICMAC (Matrice d’Impacts Croisés Multiplication Application à un Classement), this study identifies the variables shaping the implementation of regional head policies in the batik industry system. Results: MICMAC mapping shows the Regional Head Policy (KKD) as the main driving variable with the strongest direct and indirect relations, while product and process innovation, market access and promotion, and artisans’ welfare emerge as strongly dependent variables; empirically, clearer innovation-oriented directives, bureaucratic simplification, and human resource quality are central to interpreting the policy’s operational meaning. Novelty: The study contributes a MICMAC-based structural mapping of complex influence–dependence relations in regional head policy implementation for batik industry governance in Sleman. Implications: The findings support policy recommendations focused on aligning regulations with technological innovation, facilitating market access expansion, and sustaining artisans’ economic livelihoods within the creative economy ecosystem. Highlight: MICMAC positioning ranks KKD as the primary pushing variable in the system. Product–process innovation, market access–promotion, and artisan welfare appear as strongly dependent variables.

Determining Pharmaceutical Product Costs: Scientific and Practical Issues in Uzbekistan
type: item
description: This study addresses the scientific and practical challenges of determining finished product costs in pharmaceutical enterprises operating in the Republic of Uzbekistan, a critical issue in the context of economic reforms, stricter state regulation of drug pricing, and the ongoing transition to International Financial Reporting Standards that demand modern cost accounting systems. The research aims to identify deficiencies in current cost determination practices and propose improved methodologies tailored to the unique technological, regulatory, and organizational characteristics of pharmaceutical firms. Employing analytical, comparative, and monographic methods, the study examines actual accounting records and internal management reports from pharmaceutical enterprises, with particular attention to cost allocation across supply, production, laboratory testing, and packaging processes, and compares cost structures between imported and domestically manufactured products. Results reveal that material costs dominate the cost structure at approximately 50 percent, while wages and depreciation together account for nearly 30 percent; however, existing reporting practices fail to adequately disclose the distribution of indirect costs across production stages, limiting managerial control effectiveness. The novelty of this research lies in developing context-specific definitions for pharmaceutical business processes and proposing enhanced reporting formats that improve cost transparency and align with international standards. These findings have significant implications for strengthening management decision-making capabilities, improving financial reporting quality, and facilitating compliance with International Financial Reporting Standards in Uzbekistan's pharmaceutical sector.

The Efficacy of Bayesian Analysis in Predicting Stock Prices
type: item
description: General Background: Stock price prediction remains a central concern in financial economics due to its role in guiding investment decisions and managing market risk. Specific Background: Conventional forecasting techniques often inadequately address uncertainty, adaptability to new information, and the integration of prior knowledge, whereas Bayesian analysis offers a probabilistic framework that updates beliefs using historical and incoming data. Knowledge Gap: Despite growing interest in Bayesian methods within finance, empirical evidence demonstrating their practical efficiency in closely matching predicted and actual stock prices remains limited. Aims: This study aims to examine the efficiency of Bayesian analysis as a technical tool for predicting stock prices and supporting investor decision-making. Results: The findings indicate that Bayesian analysis generates predictions with minimal deviation from actual stock prices, confirming the robustness and reliability of the model. Novelty: The study reinforces the applied value of Bayesian analysis by empirically demonstrating its predictive efficiency within a real stock market context. Implications: These results suggest that Bayesian-based forecasting can enhance investors’ analytical independence, reduce reliance on costly external financial analysts, and promote more informed, data-driven investment strategies in dynamic financial markets. Keywords : Bayesian Analysis, Stock Price Prediction, Bayesian Forecasting Models, Financial Time Series, Investment Decision Making Highlight : Forecast outputs closely matched observed market values, indicating minimal deviation across tested periods. Continuous updating with incoming information improved adaptability under changing market conditions. Empirical application demonstrated practical usefulness for investment decision-making without reliance on external advisors.

Development Prospects and Recommendations for Improving Methods for Assessing Digital Investment Potential
type: item
description: General Background: Economic growth represents a fundamental indicator of national development, primarily influenced by macroeconomic variables including inflation rates and banking sector liquidity, which respectively determine price stability and financial intermediation capacity. Specific Background: While previous research has examined inflation and growth relationships independently, the Russian Federation's transition economy provides a unique context for analyzing these dynamics, particularly given its significant financial stability fluctuations between 2000 and 2024. Knowledge Gap: The joint interactive effects of inflation and banking sector liquidity on economic growth remain inadequately explored, especially for transition economies where structural and institutional characteristics differ substantially from developed markets. Aims: This study empirically investigates the relationship between inflation, banking sector liquidity, and GDP growth in the Russian Federation using ordinary least squares regression with robust standard errors and logarithmic transformations applied to annual data from 2000 to 2024. Results: The analysis reveals that inflation exhibits a positive and statistically significant effect on GDP growth (coefficient = 0.507, p = 0.0001 in the log-log-log model with R² = 0.650), while banking sector liquidity demonstrates a weaker, secondary impact requiring cautious interpretation. Novelty: This research uniquely examines inflation and banking liquidity as joint interactive economic phenomena rather than isolated variables, employing comprehensive model comparisons including multiple logarithmic transformation approaches. Implications: These findings suggest that controlled inflation management can stimulate economic activity and sustainable growth, while banking liquidity plays a supportive role, offering valuable guidance for central banks and policymakers in transition economies regarding monetary policy formulation and financial st…

Reducing Warehouse Errors Using FMEA and Poka-Yoke at Bonded Logistics Center
type: item
description: General Background Warehouse operations play a critical role in maintaining supply chain continuity, particularly within bonded logistics centers subject to strict customs regulations. Specific Background At the bonded logistics center warehouse of PT XYZ, frequent operational errors in receiving and picking processes have resulted in customer claims and potential customs penalties. Knowledge Gap Despite the operational risks, structured risk prioritization and systematic error-prevention mechanisms in bonded warehouse contexts remain insufficiently documented. Aims This study aims to identify, prioritize, and mitigate operational errors in receiving and picking activities using Failure Mode and Effect Analysis and Poka Yoke. Results The analysis reveals that the highest risk in receiving arises from failure to inspect sampling goods across different raw material types, while incorrect item retrieval constitutes the most critical risk in picking, both indicated by elevated Risk Priority Number values. Novelty This study integrates FMEA-based risk prioritization with control and warning-based Poka Yoke mechanisms specifically tailored to bonded warehouse operations. Implications The proposed revisions to work instructions, automated barcode input, pick-to-light systems, and priority rack arrangements provide a structured approach to reducing recurring errors, supporting customs compliance, and strengthening warehouse reliability within bonded logistics environments. Highlights: Critical risks were concentrated in inspection omissions and order retrieval mismatches. Risk Priority Number analysis enabled clear prioritization of operational failures. Preventive mechanisms combined procedural controls with visual warning systems. Keywords: FMEA, Picking, Poka Yoke, Receiving, Risk Mitigation

Review Of Removal of Heavy Metal Ions from Water by Complexation-Assisted Ultrafiltration
type: item
description: The escalating contamination of water resources by heavy metal ions poses critical environmental and public health challenges, necessitating efficient remediation technologies. This review examines the application of Complexation-Assisted Ultrafiltration (CP-UF), alternatively termed Polymer-Enhanced Ultrafiltration (PEUF), as an advanced membrane-based separation process for removing toxic heavy metals from aqueous solutions. The study systematically analyzes two distinct approaches: synthetic polymers including Polyethylene Glycol (PEG 5000) and Diethylaminoethyl-cellulose (DEAE-cellulose) for zinc and cadmium removal, and natural biopolymer Carboxymethyl Cellulose (CMC) for copper, nickel, and chromium elimination. Through comprehensive evaluation of experimental data from ultrafiltration membrane systems operated under varying conditions, the research demonstrates that DEAE-cellulose achieves exceptional rejection rates up to 99% for Zn(II) at pH 9.0 and 300 kPa pressure, while CMC exhibits superior performance exceeding 97% rejection for Cu(II), Ni(II), and Cr(III) at neutral to alkaline pH conditions. Critical operational parameters including solution pH, applied transmembrane pressure, membrane molecular weight cut-off, and polymer concentration significantly influence both permeate flux and metal ion retention efficiency. The novelty of this work lies in the comparative assessment of synthetic versus natural polymeric ligands, revealing that amino-functionalized DEAE-cellulose forms stable coordination complexes through nitrogen electron donation, whereas CMC utilizes carboxyl and hydroxyl groups for metal binding in pH-dependent octahedral or square planar configurations. Furthermore, the study establishes the economic and environmental feasibility of polymer regeneration through pH adjustment or chemical cleaning cycles, enabling multiple reuse iterations. These findings advance membrane separation theory by validating osmotic pressure models in complexati…

Efficiency of Village Regulations in Indonesia
type: item
description: Background: Village regulations constitute a fundamental legal instrument in Indonesia’s regional autonomy framework, positioning villages as the lowest yet autonomous level of governance. Specific background: The enactment of Law Number 6 of 2014 on Villages provides a legal basis for villages to formulate regulations reflecting community aspirations, democratic values, and local wisdom. Knowledge gap: Despite this framework, the efficiency of village regulations remains constrained by regulatory inconsistency, political dynamics, and limited institutional capacity at the village level. Aims: This study examines the efficiency of village regulations through the construction of legal politics based on philosophical, juridical, and sociological foundations. Results: The findings indicate that regulatory alignment across levels of government and village institutional capacity play a central role in shaping regulatory efficiency. Novelty: This research positions village regulation efficiency as a product of legal–political construction rather than administrative compliance. Implications: Strengthening participatory mechanisms and harmonizing legal frameworks are essential to support efficient village governance and sustainable local development in Indonesia. Highlights Village regulations operate within legal and political constraints. Regulatory alignment supports efficient village governance. Institutional capacity shapes regulatory implementation at village level. Keywords Village Regulations, Legal Politics, Regional Autonomy, Local Governance, Participatory Governance

Political Dynasties Undermine Democratic Governance and Constitutional Integrity in Indonesia
type: item
description: Political dynasties represent a systemic challenge to Indonesia’s constitutional democracy by consolidating hereditary power that contradicts the principles of meritocracy, equal political access, and institutional accountability. This research aims to analyze how political dynasties distort democratic governance and weaken constitutional mechanisms that safeguard state integrity. Using a library research method supported by systematic content analysis of academic literature, legal sources, and policy documents, the study finds that dynastic politics institutionalize oligarchic power structures, suppress competitive leadership regeneration, and increase risks of corruption, collusion, and nepotism. The findings demonstrate that dynastic networks interfere with the separation of powers, politicize public resource allocation, bias representative functions toward familial interests, and reduce institutional autonomy within the constitutional framework. Although dynasties may provide policy continuity in certain contexts, these advantages are conditional and outweighed by structural threats to legal integrity and public trust. The novelty of this study lies in extending the discussion from electoral and regional governance to the broader constitutional domain, characterizing dynastic politics as a constitutional disruption rather than merely a political phenomenon. The implications suggest the need for transparent political recruitment, regulatory restrictions on hereditary candidacy, enhanced oversight mechanisms, and civic education to reinforce democratic resilience. These measures are essential to prevent the normalization of hereditary power and to protect constitutional democracy in Indonesia from long-term institutional degradation. Highlights • Political dynasties weaken constitutional accountability and democratic governance • Hereditary power restricts leadership succession and public institutional autonomy • Oligarchic networks increase corruption risks and d…

Legal Protection for Wives in Joint Property Division After Divorce
type: item
description: General Background: The division of joint property following divorce remains a central issue in Indonesian family law, particularly under the normative framework of the Marriage Law and the Compilation of Islamic Law, which traditionally emphasize equal distribution. Specific Background: In practice, rigid application of a 50:50 division often fails to address situations where one spouse bears a dominant economic role, especially in cases involving wives as primary breadwinners. Knowledge Gap: There is limited doctrinal clarity on how courts should reconcile formal equality norms with factual disparities in economic contribution within marriage. Aims: This study aims to analyze legal protection for wives in joint property disputes where husbands fail to contribute economically, as reflected in Blitar Religious Court Decision Number 1560/Pdt.G/2023/PA.BL. Results: Using a normative juridical method with statutory, conceptual, and case approaches, the study finds that the court allocated 80% of joint property to the wife and 20% to the husband, based on evidence of the wife’s exclusive financial contribution and the husband’s failure to fulfill economic obligations. Novelty: The decision demonstrates judicial recognition that justice in joint property division need not follow a mathematical formula, but may adopt proportional distribution grounded in substantive justice. Implications: This ruling provides an important precedent for strengthening legal protection for wives, affirming that factual economic contributions and vulnerability after divorce must guide equitable resolution of joint property disputes in Indonesian religious courts. Highlights: Judicial reasoning prioritized factual economic roles over formal equal-sharing norms. Proportional allocation was grounded in evidence of exclusive financial responsibility. The ruling strengthens doctrinal support for equity-based asset distribution in divorce cases Keywords: Joint Property, Legal Protection for Wife, D…

Executive–Legislative Relations in Appointing the Indonesian National Police Chief
type: item
description: General Background The post-amendment 1945 Constitution establishes Indonesia as a presidential system with the President holding supreme executive authority, supported by a framework of checks and balances. Specific Background Within this framework, Article 11 paragraph (1) of Law No. 2 of 2002 requires approval from the House of Representatives in appointing the Chief of the Indonesian National Police, generating sustained constitutional and theoretical debate. Knowledge Gap Existing discussions have not sufficiently clarified whether this approval mechanism constitutes a limitation on presidential authority or operates as a confirmation instrument consistent with presidentialism. Aims This study aims to examine the conformity of the DPR approval requirement with presidential system principles under the 1945 Constitution and to analyze its implications for presidential executive authority. Results Using normative legal research with legislative, conceptual, and historical approaches, the study finds that DPR involvement functions as a confirmation power within the checks and balances mechanism rather than a transfer or reduction of executive authority. Novelty The study demonstrates that the approval mechanism preserves the President’s role as the sole proposer of candidates while situating legislative participation within constitutionally justified oversight. Implications These findings affirm that DPR approval strengthens public accountability and institutional legitimacy without altering the fundamental structure of Indonesia’s presidential system, thereby supporting constitutional consistency and governance stability. Highlights: DPR participation operates as a confirmation mechanism rather than an appointment authority. Presidential control over national security leadership remains constitutionally intact. Legislative involvement contributes to accountability and institutional legitimacy. Keywords : Presidential System, Checks and Balances, DPR Approval, Exec…

Transitional Legal Protection through Physical Possession and Civil Remedies for Unregistered Girik Land in Indonesia
type: item
description: General Background Land remains a fundamental economic and social asset, and legal certainty in land administration is central to rights protection. Specific Background Girik is still widely used in Jakarta, Banten, and West Java as evidence of historical control over former customary land, yet its legal position has weakened after Government Regulation No. 18 of 2021 on land registration, with a recognition deadline of 2 February 2026. Knowledge Gap The available transitional legal safeguards and practical obstacles for girik holders whose parcels remain outside the national land administration system require clearer articulation. Aims This study examines the forms and mechanisms of legal protection for unregistered girik holders and identifies the main barriers they face. Results Using a normative juridical approach, the study finds that safeguards remain available through recognition of physical control, access to civil litigation provided no good-faith protected certificate exists, and the state obligation to systematically organize land registration; however, low public awareness, BPHTB cost burdens, limited historical documentation, and institutional capacity constraints hinder optimal legal certainty. Novelty The study consolidates a transitional protection framework that links physical possession recognition and civil remedies to the post-deadline evidentiary shift under PP 18/2021. Implications The study recommends accelerating PTSL, subsidizing registration fees, harmonizing BPHTB regulations, and digitizing legacy evidence to support an inclusive transition to formal land titles. Highlights: Historical tax-based documentation becomes limited to evidence of physical control after 2 February 2026. Civil claims remain available unless a good-faith certificate is legally protected. PTSL acceleration, fee subsidies, BPHTB harmonization, and legacy-evidence digitization are proposed to advance legal certainty. Keywords: Girik Land, Legal Protection, Legal Certa…

Comparison of Indonesian and US Bankruptcy Laws in the Protection of Creditors and Debtors
type: item
description: General Background Bankruptcy law functions as a collective debt resolution mechanism intended to balance legal certainty, economic stability, and fairness between creditors and debtors in modern business systems. Specific Background Indonesia regulates bankruptcy through Law Number 37 of 2004 on Bankruptcy and Suspension of Debt Payment Obligations, while the United States applies the U.S. Bankruptcy Code, particularly Chapters 7 and 11, reflecting different legal traditions and policy orientations. Knowledge Gap Despite extensive discussions on each system, systematic comparison focusing on creditor and debtor protection principles remains limited in highlighting structural and philosophical distinctions. Aims This study aims to compare the bankruptcy regimes of Indonesia and the United States with emphasis on mechanisms, principles, and legal protections afforded to creditors and debtors. Results The findings show that both systems recognize bankruptcy as a collective proceeding, apply creditor priority rules, and provide liquidation and reorganization pathways; however, Indonesia emphasizes procedural simplicity and creditor certainty, whereas the United States prioritizes debtor protection through automatic stay, debtor-in-possession, and reorganization-oriented frameworks. Novelty The study presents an integrated comparative analysis that links procedural design with underlying legal philosophy in both jurisdictions. Implications These findings offer a conceptual reference for bankruptcy law reform in Indonesia by identifying comparative elements that may support a more balanced protection structure for creditors and debtors within evolving economic conditions. Highlights: Both jurisdictions adopt collective debt settlement with structured creditor priority arrangements. Indonesia relies on simplified procedural thresholds, while the United States applies debtor-centered reorganization mechanisms. Divergent legal philosophies shape distinct institutional roles…

Synergy Between State Administrative Law And Criminal Law In Asn Discipline Enforcement
type: item
description: General Background: Discipline enforcement among State Civil Apparatus (ASN) constitutes a fundamental pillar of clean and accountable governance within a constitutional state framework. Specific Background: In practice, disciplinary violations by ASN frequently intersect with criminal law, particularly in cases involving abuse of authority, corruption, and misconduct that threaten public trust, creating risks of overlapping authority and sanctions. Knowledge Gap: Existing discussions often address administrative and criminal mechanisms separately, leaving uncertainty regarding their coordinated application in ASN discipline enforcement. Aims: This study examines the relationship between State Administrative Law and Criminal Law in enforcing ASN discipline through a normative juridical approach based on administrative governance regulations and Government Regulation Number 94 of 2021. Results: The findings demonstrate that the two legal regimes operate in a complementary manner, with administrative law functioning as a supervisory and corrective framework, while criminal law is applied when violations exceed administrative boundaries and cause public harm. Novelty: This research emphasizes the principle of ultimum remedium as the primary normative basis for determining sanction priority, positioning criminal sanctions as a last legal measure. Implications: The study provides structured guidance for civil service development authorities and law enforcement institutions to ensure proportional, coordinated, and legally certain handling of ASN disciplinary violations within an integrated governance system. Highlights • Administrative sanctions operate as the primary supervisory mechanism in ASN discipline handling • Criminal proceedings are reserved for violations exceeding administrative responsibility and public interest thresholds • The ultimum remedium principle structures sanction prioritization within a layered accountability system Keywords ASN Discipline; State …

Legal Weaknesses in Enforcing Good Governance Principles in Licensing Corruption
type: item
description: General Background: The General Principles of Good Governance constitute fundamental norms in state administrative law that guide the legality of governmental actions. Specific Background: In Indonesia’s licensing administration, these principles are formally regulated to ensure legal certainty, transparency, accountability, and public interest, yet licensing practices frequently deviate through abuse of authority and corruption cases. Knowledge Gap: Existing enforcement mechanisms tend to prioritize criminal prosecution without first addressing administrative violations, resulting in weak integration between administrative law and criminal law. Aims: This study aims to analyze juridically the enforcement of Good Governance Principles in licensing corruption cases and to clarify the proper qualification of such violations within the administrative law framework. Results: The findings demonstrate that violations of Good Governance Principles in licensing constitute abuse of authority that should be initially addressed as administrative violations before criminal proceedings, in order to ensure legal coherence. Novelty: This study emphasizes the juridical positioning of administrative sanctions as a preliminary mechanism prior to criminal liability in licensing corruption cases. Implications: Strengthening regulations, internal supervision by governmental auditors, the role of the Ombudsman, and licensing digitalization is essential to support transparent, accountable, and clean governance based on administrative law principles. Highlights • Licensing corruption reflects systemic violations of good governance principles through abuse of administrative authority • Administrative accountability remains weak due to limited integration between administrative and criminal legal frameworks • Strengthening supervisory institutions and digital licensing systems is central to clean and accountable governance Keywords General Principles Of Good Governance; Abuse Of Authority; L…

Green Marketing, Greenwashing, and Premium Pricing Effects on Agrochemical Sales Performance
type: item
description: General Background: The agrochemical industry faces growing public scrutiny as sustainability concerns and environmental risks of synthetic chemicals intensify, prompting firms to integrate sustainability-oriented strategies into their business models. Specific Background: In Indonesia, agrochemical companies increasingly rely on green marketing communication, sustainability claims, and premium pricing to position green chemical products amid regulatory pressure and rising environmental awareness. Knowledge Gap: Empirical evidence remains limited regarding how green marketing, greenwashing practices, and premium pricing are simultaneously associated with sales performance in the agrochemical sector, particularly from the perspective of marketing practitioners. Aims: This study examines the relationships between green marketing strategies, greenwashing practices, and premium pricing with the sales performance of green chemical products, while assessing the moderating role of premium pricing. Results: Quantitative analysis using regression and moderated regression analysis indicates that green marketing, greenwashing, and premium pricing are each positively and significantly associated with sales performance, whereas premium pricing does not significantly moderate the relationships between green marketing or greenwashing and sales performance. Novelty: The study demonstrates that, within the Indonesian agrochemical context, greenwashing practices can be associated with short-term sales performance alongside green marketing and premium pricing. Implications: The findings suggest that agrochemical firms should prioritize credible and transparent sustainability communication and apply value-based pricing, as sales performance is driven by direct strategic signals rather than interaction effects among sustainability marketing and pricing strategies. Highlights: Sustainability-oriented communication shows a positive association with product sales outcomes. Short-term marke…

Eradication of Human Trafficking Crimes in Myanmar
type: item
description: General Background Human trafficking constitutes a serious form of transnational organized crime that directly violates human rights and disproportionately targets vulnerable populations, particularly migrant workers. Specific Background In Southeast Asia, Myanmar—especially the Myawaddy region following the 2021 coup—has emerged as a hub for online scamming operations and forced labor exploitation involving Indonesian nationals. Knowledge Gap Despite extensive victim repatriation efforts, limitations remain in cross-border law enforcement due to the absence of bilateral extradition arrangements and ongoing political instability in Myanmar. Aims This study examines Indonesia’s juridical responses to trafficking cases involving Indonesian citizens in Myanmar by analyzing the fulfillment of legal elements under Law No. 21 of 2007 and the application of international criminal law principles. Results The findings demonstrate that the cases meet all constituent elements of trafficking, namely actus reus, means, and mens rea, enabling Indonesia to invoke active and passive nationality principles, supported by Mutual Legal Assistance, INTERPOL Red Notice mechanisms, and ASEAN cooperation frameworks. Novelty The study highlights the strategic reliance on regional and international legal instruments as substitutes for formal extradition in a conflict-affected jurisdiction. Implications Strengthening ASEAN commitments, advancing an ASEAN Extradition Treaty, and optimizing existing cooperative mechanisms are essential to reinforce cross-border accountability and protection of Indonesian victims of human trafficking. Highlights: Trafficking cases involving Indonesian citizens satisfied all statutory elements under national anti-trafficking law. Active and passive nationality principles provide a legal basis for prosecution and victim protection beyond territorial limits. Regional and international cooperation mechanisms function as critical alternatives amid absent bilateral ex…

Muhallil Marriage in Islamic Law and Women’s Rights
type: item
description: General Background: Muhallil marriage, conducted after a triple divorce to permit remarriage with a former husband, remains a contested issue in Islamic family law due to its ethical and legal implications. Specific Background: Classical jurisprudence debates its formal validity, while contemporary practices reveal recurring manipulation that places women in vulnerable positions. Knowledge Gap: Existing studies largely address doctrinal legality or socio-legal aspects, with limited integration of feminist jurisprudence and maqasid al-shariah, particularly within the Indonesian context. Aims: This study aims to examine the concept and practice of muhallil marriage through classical and contemporary Islamic legal thought and to critically assess it using feminist jurisprudence and maqasid al-shariah perspectives. Results: Based on a qualitative literature review of fiqh texts, fatwas, religious court decisions, and feminist legal scholarship, the findings indicate that muhallil marriage contradicts the objective of preserving human dignity (ḥifẓ al-‘irḍ) and undermines gender justice within maqasid al-shariah. Feminist jurisprudence identifies the practice as instrumentalizing women for the interests of others. Novelty: The study integrates Jasser Auda’s maqasid framework with feminist jurisprudence, an approach rarely combined in prior research on muhallil marriage. Implications: The findings support the need for reformulating Islamic family law to ensure substantive protection of women’s rights while remaining grounded in the normative objectives of Islamic law. Highlights: The practice conflicts with the objective of preserving human dignity within Islamic legal principles. Gender injustice emerges through the treatment of women as legal instruments in marital arrangements. Integrating maqasid analysis with feminist legal theory offers a comprehensive framework for family law reform. Keywords: Muhallil Marriage, Islamic Family Law, Maqasid Al-Shariah, Feminist Juri…

Intellectual Property Rights as Fiduciary Collateral in Indonesian Legal Framework
type: item
description: General Background Intellectual Property Rights have evolved from moral recognition instruments into economically valuable intangible assets within modern legal systems. Specific Background In Indonesia, positive law has formally recognized Intellectual Property Rights as movable intangible objects eligible for fiduciary security through Law No. 42 of 1999 and Government Regulation No. 24 of 2022, particularly within the creative economy sector. Knowledge Gap Despite normative recognition, significant obstacles remain in valuation mechanisms, institutional readiness, and execution procedures, limiting practical utilization of Intellectual Property Rights as fiduciary collateral. Aims This study aims to examine the legal construction of Intellectual Property Rights as fiduciary objects and to analyze the legislative rationale for such classification using Richard A. Posner’s Economic Analysis of Law approach. Results The findings demonstrate that Intellectual Property Rights satisfy property law criteria as fiduciary objects due to their economic value and transferability, yet Indonesia’s fiduciary system exhibits structural inefficiencies, especially in asset appraisal and enforcement certainty. Novelty This research integrates Indonesian fiduciary law with Posner’s efficiency-based legal theory to explain the normative justification of Intellectual Property Rights as bankable collateral. Implications The study highlights the need for regulatory synchronization, institutional reform, and valuation infrastructure to support Intellectual Property–based financing aligned with principles of legal certainty and economic efficiency. Highlights: Indonesian positive law categorizes intangible rights with economic value as fiduciary objects. Valuation and execution uncertainty constrains acceptance of intangible collateral by financial institutions. Efficiency-based legal reasoning supports collateralization of non-physical economic assets. Keywords: Intellectual Property Ri…

Independent Majelis Disiplin Profesi Ensures Legal Certainty in Health Law
type: item
description: General Background: Indonesia’s health legal system has introduced a dedicated professional discipline mechanism through the Majelis Disiplin Profesi (MDP) under Law Number 17 of 2023 on Health. Specific Background: Articles 304–309 position MDP as the initial forum to examine alleged breaches of medical and health professional discipline prior to criminal investigation, reflecting a quasi-judicial role within health governance. Knowledge Gap: The statutory design raises unresolved concerns regarding guarantees of institutional autonomy and protection from executive intervention, despite the direct significance of MDP recommendations for subsequent criminal and civil processes. Aims: This study articulates the urgency of structural independence for MDP by mapping its juridical position, independence dimensions (institutional, functional, and administrative), and normative risks within the lex specialis framework for medical disputes. Results: The analysis identifies that insufficient independence may generate legal uncertainty, weaken objectivity of recommendations, and risk constraining constitutional access to justice, including tensions with equality before the law, while also creating overlap risks with the general judiciary if recommendations are treated as an absolute procedural prerequisite. Novelty: The article synthesizes MDP’s quasi-judicial character with a three-dimensional independence model to assess the feasibility of lex specialis discipline mechanisms under the 2023 Health Law. Implications: Strengthening MDP’s institutional design and ensuring transparent examination procedures are positioned as priority measures to sustain professional accountability, balanced protection for patients and health workers, and public trust in disciplinary adjudication. Highlights: The disciplinary mechanism is placed as the initial examination stage before investigative procedures begin. Autonomy deficits are linked to risks of non-objective recommendations and const…

Use of Artificial Intelligence Methods in Risk Assessment and Prediction of Preeclampsia
type: item
description: General Background: Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality worldwide, with early prediction remaining a critical challenge in obstetric care. Specific Background: Conventional diagnostic approaches based on clinical and isolated biochemical markers often identify the disorder at advanced stages and fail to capture its multifactorial pathophysiology. Knowledge Gap: There is limited integration of multidimensional clinical, biochemical, and Doppler data into robust predictive models capable of early and individualized risk assessment. Aims: This study aimed to develop and evaluate a machine learning–based model for early prediction of preeclampsia using comprehensive antenatal data. Results: In a retrospective cohort of 1,200 pregnant women, the Extreme Gradient Boosting (XGBoost) model demonstrated superior performance, achieving an AUC of 0.94, sensitivity of 91%, specificity of 89%, and overall accuracy of 90%, outperforming random forest, support vector machine, and logistic regression models. Key predictors included mean arterial pressure, maternal age, uterine artery pulsatility index, placental growth factor, and soluble fms-like tyrosine kinase-1. Novelty: The study integrates 35 heterogeneous parameters into an AI-driven framework, highlighting the strength of ensemble learning in capturing nonlinear risk patterns. Implications: AI-based predictive tools offer significant potential for early identification of high-risk pregnancies, enabling targeted preventive interventions and advancing precision obstetrics to reduce preeclampsia-related adverse outcomes.

Features of The Disease Management in the Appendical Infiltrate
type: item
description: General Background: Acute appendicitis represents the most prevalent acute abdominal pathology requiring surgical intervention. Specific Background: Appendicular infiltrate, occurring in 1-10% of acute appendicitis cases, poses diagnostic challenges that frequently result in inappropriate treatment selection and unjustified surgical procedures. Knowledge Gap: Despite its clinical significance, standardized diagnostic criteria and management protocols for appendicular infiltrate remain inadequately defined, particularly regarding intraoperative recognition and intervention decisions. Aims: This study analyzed diagnostic approaches and treatment outcomes in patients presenting with appendicular infiltrate to establish evidence-based management protocols. Results: Among 3,567 patients treated for acute appendicitis between 2020-2024, appendicular infiltrate was identified in 38 cases (1.1%). Delayed presentation constituted the primary etiological factor (75%), while atypical appendiceal positioning complicated diagnosis in 7.9% of cases. Conservative management achieved successful resolution in 78.9% of patients, whereas 21.1% required surgical intervention due to abscess formation. Intraoperative identification of infiltrate in six patients necessitated procedure termination with drainage placement; one attempted appendectomy resulted in postoperative complications. Novelty: This investigation establishes that immediate cessation of surgery upon intraoperative infiltrate recognition minimizes complications. Implications: These findings emphasize prioritizing conservative management and avoiding appendectomy when infiltrate is encountered operatively.

description: General Background: Accurate assessment of liver functional reserve remains critical in surgical practice, as hepatic dysfunction substantially elevates postoperative morbidity and mortality risks. Specific Background: Conventional biochemical markers (ALT, AST, bilirubin) predominantly reflect cytolysis and cholestasis but fail to evaluate hepatocellular energetic status or regenerative capacity. Knowledge Gap: Current diagnostic approaches lack objective quantitative indicators that directly measure mitochondrial function and viable hepatocyte populations in surgical patients. Aims: This study evaluated a novel prognostic coefficient based on the ratio of cytochrome C to TMPD oxidase mitochondrial activities for quantifying liver parenchymal preservation in patients with hepatobiliary surgical diseases. Results: Analysis of 24 patients demonstrated strong inverse correlation between coefficient values and viable hepatocyte percentages. Coefficients of 2.5-3.5 units indicated favorable prognosis, 5-7 units signaled elevated complication risk, while values ≥8 units predicted unfavorable outcomes, irrespective of standard biochemical parameters. Novelty: Unlike traditional markers, this coefficient directly reflects mitochondrial respiratory chain integrity and hepatocellular viability through objective biochemical measurements. Implications: The proposed coefficient serves as an integrated quantitative marker of hepatic functional reserve, enabling improved surgical risk stratification and outcome prediction in hepatobiliary surgery. Highlight : The cytochrome C to TMPD oxidase ratio correlates better with hepatocyte viability than standard biochemical markers in both experimental and clinical contexts. Coefficient values predict postoperative outcomes: 2.5-3.5 units indicate favorable prognosis, 5-7 units suggest complications, and ≥8 units correlate with mortality. Mitochondrial dysfunction demonstrates universal quantifiable patterns across different etiologies, …

The Importance of Endolymphatic Administration of Drugs In The Treatment of Persistent Postoperative Peritoniti
type: item
description: Persistent postoperative peritonitis remains a major challenge in abdominal surgery due to high rates of septic complications, antimicrobial resistance, and insufficient drug concentrations at the site of inflammation, making optimization of regional drug delivery clinically relevant. This study aims to evaluate the clinical and immunological effectiveness of endolymphatic drug administration in the comprehensive treatment of appendicular peritonitis. A retrospective and comparative clinical study was conducted on 66 patients with appendicular peritonitis treated in surgical departments of Tashkent city clinics, divided into a main group receiving endolymphatic therapy and a control group managed with conventional treatment. Clinical severity scores, biochemical parameters, intoxication indices, and immunological markers were analyzed using non-parametric statistical methods. The results demonstrate that endolymphatic drug administration achieved higher local therapeutic concentrations, significantly improved lymphocyte subpopulations, enhanced humoral immunity indicators, reduced endogenous intoxication, and accelerated recovery compared with standard therapy. Unlike prior studies that focused primarily on systemic antibiotic regimens, this research provides empirical evidence on the immunomodulatory and detoxifying advantages of targeted endolymphatic therapy in postoperative peritonitis. These findings contribute to the theoretical understanding of lymphatic system involvement in inflammatory control and support practical and policy-oriented implications for integrating endolymphatic drug administration into surgical infection management protocols to reduce complications and improve patient outcomes. Keywords : Endolymphatic antibiotic therapy, appendicular peritonitis, immunomodulation, lymphatic drug delivery, surgical sepsis prevention, postoperative complications Highlight : Endolymphatic therapy increases total T-lymphocytes 1.41-fold and improves immunoglob…

Endolymphatic Drug Delivery Improves Outcomes in Persistent Postoperative Peritonitis
type: item
description: Postoperative peritonitis remains a critical challenge in contemporary surgery, with persistent complications despite conventional antibiotic therapy leading to increased mortality and prolonged recovery periods. This study investigates the therapeutic efficacy of direct endolymphatic drug therapy (TTBET) in managing persistent postoperative peritonitis following acute appendicitis. The research examined 66 patients with appendicular peritonitis treated in Tashkent surgical clinics, divided into a main group receiving endolymphatic therapy via catheterized peripheral lymphatic vessels (n=36) and a control group receiving conventional treatment (n=30). Immunological parameters including T-lymphocytes, B-lymphocytes, immunoglobulins (IgG, IgA, IgM), and neutrophil phagocytic activity were measured at baseline and day 14 post-treatment using standardized biochemical and immunological assays. Results demonstrated statistically significant improvements in the endolymphatic therapy group, with T-lymphocyte counts increasing 1.41-fold compared to controls (p=0.0022), IgG levels rising 1.7-fold versus 1.49-fold in controls, and neutrophil phagocytic activity improving 1.68-fold versus negligible change in the control group. This study provides novel evidence that endolymphatic administration achieves superior drug concentration at inflammatory sites while simultaneously modulating immune responses through direct lymphatic system engagement. The findings suggest endolymphatic therapy represents a pathogenetically sound approach for managing persistent peritonitis, offering reduced antibiotic doses, enhanced immunological recovery, and improved clinical outcomes, warranting broader clinical implementation in surgical infection management protocols.

type: item
description: General Background: Arginine deiminase (ADI) represents a promising therapeutic enzyme for treating arginine-auxotrophic cancers by catalyzing L-arginine conversion to citrulline and ammonia, exploiting the metabolic vulnerability of cancer cells deficient in arginosuccinate synthetase (ASS). Specific Background: Colorectal cancer, ranking second in mortality and third in global incidence, demonstrates heterogeneous arginine metabolism with certain tumor subtypes exhibiting impaired ASS expression, rendering them susceptible to arginine deprivation therapy. Knowledge Gap: Despite ADI's therapeutic potential, comprehensive characterization of Klebsiella pneumoniae-derived ADI and its selective cytotoxicity against colorectal cancer remains insufficiently explored. Aims: This study isolated, purified, and characterized ADI from clinically isolated K. pneumoniae strains and evaluated its selective anticancer activity against HCT-116 colorectal cancer cells versus NCM460 normal colon cells. Results: Isolate No. 5 demonstrated optimal ADI production (12 U/mg), achieving 11-fold purification through three-step chromatographic procedures yielding 32.9 U/mg specific activity with 40.9% recovery; optimal enzymatic performance occurred at pH 7 and 37°C, with Mn²⁺ and Fe³⁺ enhancing activity (120% and 105% respectively) while EDTA inhibited it (73%), confirming metalloenzyme properties; cytotoxicity assays revealed selective anticancer activity with IC₅₀ values of 390 µg/mL against HCT-116 cells and >800 µg/mL against NCM460 cells, demonstrating 2.3-fold selectivity. Novelty: This investigation provides the first comprehensive biochemical characterization of K. pneumoniae-derived ADI with demonstrated selective cytotoxicity parameters specifically targeting colorectal cancer.

Body Mass Index and Waist Circumference Associations with Blood Pressure
type: item
description: General Background: Body mass index and waist circumference are widely used anthropometric indicators to describe nutritional status and body fat distribution related to cardiovascular risk, including blood pressure changes in young adults. Specific Background: Medical students, particularly those in early academic years, are generally perceived as healthy but may experience overweight or obesity during their study period, which warrants early observation of blood pressure patterns. Knowledge Gap: Empirical evidence focusing on the relationship between body mass index, waist circumference, and systolic and diastolic blood pressure among early-year medical students remains limited and inconsistent. Aims: This study aimed to examine the relationship between body mass index and waist circumference with systolic and diastolic blood pressure among medical students of Wijaya Kusuma University Surabaya, class of 2024. Results: Based on an observational cross-sectional design involving 95 students, Pearson correlation analysis demonstrated no significant relationship between body mass index or waist circumference and systolic or diastolic blood pressure (p > 0.05). However, chi-square analysis identified a significant association between body mass index and systolic blood pressure, as well as between waist circumference and systolic blood pressure. Novelty: This study provides specific evidence from an early-year medical student population showing that anthropometric indicators are not consistently associated with blood pressure despite a substantial proportion of overweight and obesity. Implications: The findings emphasize the importance of early anthropometric screening and preventive strategies in medical students to address potential cardiovascular risk factors before clinical manifestations emerge. Highlights • Anthropometric indicators showed no consistent correlation with systolic and diastolic blood pressure • Overweight and obesity were prevalent among early-year m…

Hormonal Contraception Temporarily Suppresses Ovarian Reserve Markers with Partial Recovery
type: item
description: General Background: Hormonal contraception is widely used, yet its implications for ovarian reserve markers remain debated. Specific Background: Cross-sectional studies report lower anti-Müllerian hormone (AMH) and antral follicle count (AFC) among users, but lack baseline data to determine temporal dynamics and reversibility. Knowledge Gap: Prospective evidence with serial baseline and follow-up measures comparing contraceptive methods is limited. Aims: This study prospectively evaluated longitudinal changes in AMH, AFC, and follicle-stimulating hormone among women initiating combined oral contraceptives or levonorgestrel-releasing intrauterine devices versus non-users. Results: Mixed-effects models demonstrated significant time-by-group interactions, with early declines in AMH and AFC at three months, followed by partial recovery during continued use, while controls remained stable. Novelty: By integrating baseline and repeated measures, this study delineates functional, time-dependent suppression rather than structural ovarian damage. Implications: Findings support counseling that hormonal contraception induces temporary, reversible alterations in ovarian reserve markers and should not be interpreted as permanent fertility impairment. Keywords : Hormonal Contraception, Anti-Müllerian Hormone, Ovarian Reserve Markers, Longitudinal Cohort Study, Oral Contraceptives Highlight : AMH levels decreased 25-29% at 3 months, then partially recovered by 12 months Changes reflect temporary ovarian suppression, not permanent structural damage to ovaries Both OCP and LNG-IUD users showed similar suppression and recovery patterns

Alterations in the Adaptation of Pancreatic Enzymes to Food Quality under the Influence of Hexachlorocyclohexane and Tetramethylthiuram Disulfide
type: item
description: General Background: The pancreas demonstrates adaptive capacity to modify enzymatic secretion in response to dietary composition, a mechanism essential for efficient nutrient hydrolysis and metabolic homeostasis. Specific Background: Organochlorine pesticides, particularly hexachlorocyclohexane (HCH) and tetramethylthiuram disulfide (TMTD), have been associated with digestive system disorders, yet their effects on pancreatic enzymatic adaptation and intestinal enzyme-forming function remain inadequately characterized. Knowledge Gap: The extent to which chronic pesticide exposure disrupts the pancreas's ability to adapt enzyme secretion to qualitative changes in food composition, and how these compounds affect small intestinal hydrolytic capacity, has not been systematically investigated. Aims: This study examined the effects of chronic HCH (1/20 LD₅₀ for 30 days) and TMTD (1/20 LD₅₀ for 60 days) exposure on pancreatic enzymatic adaptation to protein-rich and fat-rich dietary stimuli in rats, alongside assessment of small intestinal enzyme-forming function. Results: Control animals exhibited adaptive increases in protease activity following protein intake and lipase activity following fat intake within intestinal chyme; HCH exposure delayed these adaptive responses, whereas TMTD completely abolished pancreatic enzymatic adaptation to food quality, with both pesticides significantly suppressing intestinal enzyme activities. Novelty: This investigation provides the first systematic evidence that organochlorine pesticides disrupt both pancreatic adaptive mechanisms and intestinal hydrolytic enzyme function in a dose-dependent and time-dependent manner. Implications: These findings indicate that pesticide exposure compromises digestive efficiency through dual mechanisms affecting pancreatic regulation and intestinal enzymatic capacity, potentially contributing to metabolic dysfunction in exposed populations.

Changes in the Activity of Small Intestinal Enzymes under the Influence of Organophosphorus Pesticides
type: item
description: General Background: Organophosphorus pesticides are widely used agricultural chemicals with known biological effects, yet their impact on digestive physiology remains incompletely understood. Specific Background: Previous research has demonstrated that chlorophos, an organophosphorus compound, suppresses intestinal enzyme activity in experimental animals, with lipase showing particular sensitivity, though comprehensive characterization of organophosphorus effects on small intestinal enzyme systems is lacking. Knowledge Gap: The detailed dose-dependent and time-dependent effects of butiphos, a commonly used organophosphorus pesticide, on the complete spectrum of intestinal digestive enzymes and the reversibility of these effects have not been systematically investigated. Aims: This study investigated the effects of acute and chronic butiphos exposure at varying doses on key small intestinal enzymes including monoglyceride lipase, glycyl-valine dipeptidase, invertase, alkaline phosphatase, and amylase in laboratory rats. Results: Monoglyceride lipase activity was consistently and profoundly suppressed (up to 9-fold reduction) across all exposure regimens, while other enzymes exhibited dose- and time-dependent wave-like fluctuations with transient increases or decreases followed by partial recovery; cessation of pesticide administration resulted in normalization of enzymatic activity and mucosal mass. Novelty: This research provides the first comprehensive characterization of butiphos-induced alterations in intestinal enzyme-forming function, revealing selective esterase inhibition and reversible enterocyte dysfunction. Implications: These findings highlight potential impairment of digestive efficiency during chronic organophosphorus pesticide exposure and underscore the high sensitivity of enterocyte enzymatic systems to these agricultural compounds.

The Organic Interrelation Between Legal Requirements and Citizens’ Moral Responsibility in the Electoral Process
type: item
description: This study investigates the interdependent relationship between legal regulation and citizens' moral responsibility in electoral processes, addressing the critical challenge that formal electoral laws alone cannot guarantee democratic legitimacy without corresponding ethical engagement from the electorate. The research aims to theoretically and practically substantiate how legal requirements and moral consciousness function as mutually reinforcing mechanisms in ensuring free, fair, and transparent elections. Employing a comprehensive methodological framework, the study integrates comparative analysis of legal systems, structural-functional approaches to electoral institutions, content analysis of legislative documents and academic literature, and sociological observation of civic behavior patterns during electoral processes. The analysis reveals that while legal norms provide essential procedural frameworks—including voting freedom, equality principles, and transparency mechanisms—their effectiveness critically depends on citizens' internalization of ethical values such as integrity, civic duty, responsibility, fairness, and political awareness. The principal finding demonstrates that electoral violations including corruption, vote-selling, and manipulation primarily stem from insufficient moral responsibility rather than legislative deficiencies, even in contexts with advanced electoral codes and technological safeguards. The novelty of this research lies in its systematic integration of legal and socio-ethical dimensions within electoral analysis, challenging purely normative approaches by establishing electoral culture as a key socio-legal factor bridging formal regulation and civic ethics. The study's implications extend to democratic governance theory and electoral reform policy, recommending continuous electoral education systems, enhanced digital civic outreach, strengthened public oversight mechanisms, and youth engagement strategies to cultivate the moral c…

Optimization of Transfer Learning VGG-16 and ResNet50 for Deep Learning-Based Classification of Edible and Poisonous Mushroom Images
type: item
description: General Background Accurate identification of edible and poisonous mushrooms is critical for food safety because high visual similarity among species often causes misclassification. Specific Background Deep learning with transfer learning using Convolutional Neural Networks has been widely applied for image-based mushroom classification, particularly through pretrained architectures such as VGG-16 and ResNet50. Knowledge Gap Nevertheless, limited comparative evidence exists regarding which architecture provides more stable and balanced performance when applied to relatively small and diverse mushroom image datasets. Aims This study compares VGG-16 and ResNet50 transfer learning models for binary mushroom toxicity classification using the Kaggle Edible and Poisonous Mushroom Images dataset consisting of 2,820 images from 47 species. Results Using a 70:15:15 training, validation, and testing split with standardized preprocessing and data augmentation, the fine-tuned VGG-16 model achieved 96% test accuracy with a loss of 0.1671, while the ResNet50 model reached 92% accuracy with a loss of 0.2991. Both models obtained a ROC AUC value of 1.000, although VGG-16 demonstrated more balanced precision, recall, and F1-scores across classes. Novelty This research presents a direct and systematic comparison of two widely used pretrained CNN architectures under identical experimental settings. Implications The findings support automated mushroom toxicity identification to assist safer mushroom consumption decisions. Highlights: The strongest model achieved 96% accuracy with lower classification loss. The alternative model produced lower accuracy under identical conditions. Both approaches reached perfect ROC AUC with differing class balance. Keywords: Deep Learning, Convolutional Neural Network (CNN), VGG-16, ReNet50, Mushroom Image Classification

Legal Noncompliance in Indonesia Additional Hajj Quota Allocation
type: item
description: General Background The administration of the Hajj pilgrimage in Indonesia is governed by Law Number 8 of 2019, which mandates fairness, transparency, and prioritization of regular pilgrims in quota management. Specific Background In 2024, Saudi Arabia granted Indonesia an additional Hajj quota intended to address prolonged waiting lists, yet its domestic distribution generated controversy due to allocations favoring special pilgrims. Knowledge Gap Existing studies largely emphasize Hajj diplomacy and service management while insufficiently examining legal compliance in the domestic allocation of additional quotas resulting from bilateral agreements. Aims This study examines the Indonesian government’s noncompliance with Law Number 8 of 2019 in distributing the additional 2024 Hajj quota from an international relations and governance perspective. Results The findings reveal discrepancies between statutory provisions and policy practices, marked by the diversion of additional quotas to special pilgrims, limited transparency in decision-making, and weak accountability mechanisms. Novelty This research integrates national interest theory and good governance principles to connect bilateral diplomacy outcomes with domestic legal adherence in Hajj administration. Implications The study underscores that diplomatic achievements in securing additional Hajj quotas must be accompanied by lawful and transparent domestic implementation to preserve public trust, uphold pilgrims’ rights, and ensure coherent governance within Indonesia’s Hajj administration framework. Highlights: Allocation practices diverged from statutory priority for long-waiting regular pilgrims. Decision-making procedures lacked public transparency and administrative accountability. Diplomatic gains were not consistently aligned with domestic legal obligations. Keywords: Noncompliance, Hajj Quota Distribution, Good Governance

The Ontological Foundations of Islamic Psychology: A Critical Comparison with Western Psychology and Its Theoretical Implications
type: item
description: General Background: Contemporary psychology has predominantly evolved within Western empiricist and materialist traditions that conceptualize human nature through biological, cognitive, and behavioral dimensions. Specific Background: In contrast, Islamic Psychology is grounded in an Islamic worldview that understands human beings as an ontological unity comprising ruh, qalb, nafs, ‘aql, and jasad, each possessing distinct ontological status. Knowledge Gap: Despite increasing applied research in Islamic counseling and psychotherapy, the ontological foundations distinguishing Islamic Psychology as an autonomous scientific paradigm remain insufficiently articulated. Aims: This study aims to formulate a coherent ontological framework of Islamic Psychology and critically compare it with the dominant ontological assumptions of Western psychology. Results: Using a qualitative–philosophical library research approach, the study demonstrates that Islamic Psychology offers an integrative and hierarchical conception of the human soul that cannot be reduced to material or cognitive processes, while Western psychological paradigms largely operate within reductionist ontologies. Novelty: The study systematically articulates the ontological structure of ruh, qalb, nafs, ‘aql, and jasad as foundational elements of Islamic Psychology, positioning them as constitutive realities rather than symbolic constructs. Implications: This ontological clarification provides theoretical, methodological, and practical foundations for positioning Islamic Psychology as a philosophically autonomous and complementary paradigm within global psychological discourse, particularly in addressing spiritual and existential dimensions of human well-being. Highlights: Islamic Psychology is grounded in an integrative ontological model uniting spiritual, rational, and bodily dimensions. Western psychological paradigms predominantly rely on materialistic and reductionist ontological assumptions. Ontological clari…
