Abstract

General Background: The growth of short video platforms has accelerated the development of digital content formats, including VTuber performances that combine animation technology, storytelling, and convergent media communication. Specific Background: VTubers use Live2D avatars and narrative content to present visual communication integrating gaming, Japanese mythology, and anime aesthetics through YouTube Shorts. Knowledge Gap: Previous studies mainly discuss VTubers in general visual communication, while limited research analyzes symbolic meaning construction in short video storytelling using semiotic approaches. Aims: This study analyzes how visual and symbolic signs construct identity and meaning in VTuber Yatagarasu no Yuta using Roland Barthes’ semiotic framework. Results: The findings show that avatar visual elements such as crow attributes and formal clothing represent literal meaning, while Minecraft creepypasta storytelling reflects symbolic themes of mystery, isolation, and digital threats. Mythological elements through characters like Herobrine, Entity 303, and Null represent digital urban legends reflecting collective fears in virtual environments. Novelty: This research integrates semiotic analysis with VTuber short video storytelling to explain layered signification in convergent media. Implications: The findings provide insights into VTuber identity formation, digital myth construction, and audience interaction patterns within virtual entertainment and digital culture studies. Highlights: Multi-Layered Sign Interpretation Reveals Symbolic Representation Within Gaming Narrative Elements. Short-Form Narrative Content Constructs Cultural Meaning in Virtual Community Interactions. Digital Legends Derived From Creepypasta Strengthen Virtual Persona Authenticity. Keywords: Vtuber Identity, Semiotic Analysis, YouTube Shorts, Digital Storytelling, Roland Barthes

Abstract

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, User Innovation, Sustainability Performance, MSMEs

Abstract

General Background: Good governance constitutes a fundamental framework for public administration aimed at ensuring transparency, accountability, participation, and justice within governmental processes. Specific Background: In Indonesia, regional governments with archipelagic characteristics face distinct administrative and geographic challenges, particularly in public service distribution, access to information, and citizen participation, as experienced by the Riau Islands Province. Knowledge Gap: Existing studies predominantly examine good governance within continental or urban contexts, while empirical analysis focusing on archipelagic regional governance remains limited. Aims: This study analyzes the application of good governance principles in regional government administration in the Riau Islands Province and identifies supporting factors, constraints, and governance-strengthening strategies aligned with archipelagic conditions. Results: The findings indicate that transparency is pursued through public information disclosure and digital governance initiatives, accountability is implemented via performance evaluation mechanisms and the Government Agency Performance Accountability System, and public participation is facilitated through development planning forums; however, persistent challenges include corruption practices, low public literacy, digital disparities, and uneven bureaucratic capacity. Novelty: This research offers a governance framework specifically formulated for archipelagic regions by integrating service-oriented bureaucratic reform, digital transformation, and multi-stakeholder collaboration. Implications: The study provides contextual insights for regional policymakers in designing governance arrangements that align with archipelagic administrative realities and support transparent, accountable, and sustainable regional administration. Highlights • Transparency initiatives rely on public information disclosure and digital governance systems• Accountability mechanisms remain predominantly procedural due to limited public engagement• Archipelagic governance requires integrated bureaucratic reform and digital coordination Keywords Good Governance; Regional Government; Archipelagic Area; Digital Governance; Public Administration

Abstract

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, Divorce, Economic Contribution, Court Decision.

Abstract

General Background: Trace elements are persistent environmental contaminants that accumulate in aquatic systems and pose ecological and health risks. Specific Background: The Al-Gharraf River in southern Iraq receives inputs from agricultural, industrial, and domestic activities, increasing concern about metal enrichment in water, sediments, and fish. Knowledge Gap: Despite regional studies, data on the simultaneous distribution and bioaccumulation of cadmium and zinc in multiple environmental compartments of this river remain limited. Aims: This study assessed concentrations of cadmium and zinc in water, sediments, and fish tissues across three months to determine contamination levels and ecological implications. Results: Findings showed pronounced elevation of both metals in December compared with November and January, with the highest accumulation recorded in sediments and in fish gills and liver, while muscles exhibited comparatively lower concentrations. The consistent month-to-month variation demonstrated active metal inputs and dynamic environmental interactions that facilitate bioaccumulation. Novelty: This study provides integrated, compartment-based evidence of trace-metal distribution in a key river system using synchronized sampling of water, sediment, and multiple fish tissues. Implications: The results underscore the urgent need for strengthened monitoring and management strategies to mitigate metal pollution and safeguard ecosystem integrity and public health.Highlight : Shows increased cadmium and zinc levels in December across all sample types. Fish organs, especially gills and liver, display clear bioaccumulation patterns. The findings underline the need for stricter environmental monitoring.

Abstract

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, Executive Authority, Police Chief Appointment

Abstract

General Background: Effective soil compaction is fundamental to the stability and durability of road infrastructure, requiring accurate modeling of soil–machine interaction. Specific Background: Rheological models have become essential tools for describing elastic, viscous, and plastic behaviors that emerge when vibrating rollers interact with diverse soils, including saline subgrade materials. Knowledge Gap: Existing studies have not fully integrated multi-zone rheological behavior into a unified analytical model capable of characterizing deformation dynamics under real vibration loading. Aims: This study aims to develop an improved multi-mass rheological model that captures the elastic, viscous, and plastic responses of soils during roller compaction and to derive analytical expressions for predicting deformation characteristics. Results: The research presents a three-mass rheological system incorporating Hooke, Newton, and Saint-Venant elements, derives coupled differential equations for soil–roller interaction, and proposes closed-form static and dynamic solutions for displacement and vibration response. The model predicts system stability, resonance susceptibility, damping behavior, and deformation under varying excitation frequencies. Novelty: The study integrates soil layer properties into a multi-zone rheological framework, offering a more comprehensive representation of compaction mechanics than prior single-zone or simplified models. Implications: The findings provide a scientific basis for optimizing roller parameters, preventing resonance, improving compaction uniformity, and enhancing predictive simulations in road construction engineering.Highlight : The study explains how rheological models represent elastic, viscous, and plastic behavior during roller–soil interaction for more accurate compaction analysis. Various models—Hooke, Newton, Maxwell, Kelvin, and Bingham—are applied to describe soil deformation under dynamic loading. A three-mass rheological system is developed to predict vibration stability, resonance risk, and soil response during compaction.

Abstract

General Background: Environmental pollution from heavy metals and organic contaminants has escalated globally, generating complex biological disruptions across molecular, cellular, and ecological levels. Specific Background: Advances in high-throughput sequencing and multi-omics technologies have revealed that pollutants induce genomic and epigenetic alterations, yet interpreting these multidimensional datasets remains challenging. Knowledge Gap: Existing studies lack integrated analytical frameworks capable of linking pollutant exposure with genome-wide molecular responses in a precise and predictive manner. Aims: This review synthesizes current evidence on pollutant-induced molecular changes and evaluates the potential of artificial intelligence (AI) to model and predict biological responses. Results: Recent applications of machine learning—such as Random Forests, Support Vector Machines, and Convolutional Neural Networks—demonstrate strong performance in identifying key genetic markers, forecasting epigenetic modifications, and estimating organismal vulnerability before clinical symptoms appear. Novelty: This article highlights the emerging role of AI-driven genomic modeling as a transformative approach that integrates environmental and genomic datasets to capture multilevel biological responses with high accuracy. Implications: The integration of AI with genomics offers a proactive strategy for early detection of pollution-induced molecular changes, enhances environmental risk assessment, and informs targeted remediation, biodiversity protection, and long-term ecosystem management.Highlight : Environmental pollutants cause DNA methylation changes, histone modifications, and disruptions in cellular defense mechanisms. Machine learning algorithms predict epigenetic changes and identify genetic markers before physiological symptoms manifest. AI integration enables early pollution detection, bioremediation support, and proactive ecosystem management.

Abstract

Background: The service sector serves as a critical driver for enhancing entrepreneurial activity and addressing socio-economic challenges such as unemployment and poverty in developing economies. Knowledge Gap: While Uzbekistan has established comprehensive legal and institutional frameworks to support entrepreneurship, limited empirical research exists on the actual entrepreneurial activity levels and barriers faced by populations at the community (mahalla) level in the service sector. Aims: This study conducts a sociological assessment of entrepreneurial activity in Samarkand region's service sector, evaluating socio-economic factors, existing barriers, and opportunities through quantitative and qualitative methods. Results: Survey data from 496 respondents revealed that although 74.8% expressed desire to start businesses, only 25.1% possessed adequate family assets for entrepreneurial ventures. Key obstacles identified included insufficient capital-property resources (42.2% needed machinery/equipment, 47.1% required production buildings), limited financial literacy, and weak institutional support at the neighborhood level, with 80.7% reporting no practical assistance from local government programs. Novelty: This research employs a mahalla-based methodological approach to assess entrepreneurial readiness, providing granular insights into community-level barriers previously overlooked in regional development studies. Implications: Findings underscore the necessity for targeted interventions including enhanced financial literacy programs, improved neighborhood-level institutional support mechanisms, and comprehensive capital-property assistance schemes to effectively stimulate entrepreneurial activity among Uzbekistan's population.Highlight : The study reveals that 74.8% of respondents desire to start businesses, but only 25.1% have adequate opportunities to utilize family assets as initial capital. Major barriers include lack of machinery and equipment (42.2%), production facilities (47.1%), and reliance on mixed financing sources combining bank loans and personal funds (39.6%). Institutional support remains inadequate, with 80.7% of respondents receiving no practical assistance from neighborhood-level government programs, indicating gaps in community-based entrepreneurship development mechanisms.

Abstract

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 Certainty
