Heart disease is the leading cause of death in Indonesia and globally, necessitating an early screening system that is both accurate and clinically trustworthy. Although XGBoost demonstrates high predictive performance, its black-box nature undermines clinical trust, while low recall risks missed diagnosis an unacceptable consequence in population screening, especially in middle-income countries with limited healthcare resources. This study aims to develop a sensitive, transparent, and implementation-ready heart disease screening framework through the integration of SHAP-based Explainable AI. The CDC's Indicators of Heart Disease dataset (319,795 samples) was processed according to WHO/CDC standards, followed by class imbalance handling, hyperparameter optimization using RandomizedSearchCV, evaluation based on metrics sensitive to minority classes (AUC, recall, F1-score, AUC-PR), and threshold tuning to maximize recall. The baseline model showed a very low recall of 12.18%. After optimization and threshold tuning at 0.10, the model achieved recall >96% (96.79%) with a G-mean of 0.7477, supported by SHAP interpretation stability and the ability to capture non-linear interactions between advanced age (AgeCategory_WHO) and poor general health (GenHealth). SHAP analysis confirmed the alignment of dominant features with medical evidence, and its visualizations provide transparent explanations for healthcare professionals indicating its potential implementation as an interpretable clinical decision support system.

This study examines the sacred meaning of the agricultural cycle in the life of the indigenous community of the Detunggali Communal Land through an ethnographic approach. Agricultural rituals accompanying all stages of farming from land clearing, seed preparation and planting, crop maintenance, to harvesting are understood as cultural practices that integrate spiritual, social, and ecological dimensions. The study aims to explore how these agrarian rites function in shaping relationships between humans, nature, and ancestors, while sustaining the collective identity of the Detunggali community. A qualitative descriptive method was employed, with data collected through in-depth interviews, participant observation, and documentation involving customary elders and community members. The findings reveal that farming activities in Detunggali are not merely economic endeavors but are deeply embedded in sacred values expressed through symbols, prayers, and customary rules. Agrarian rituals play a crucial role in maintaining cosmic balance, strengthening social cohesion, and fostering ecological awareness rooted in local cosmology. The study highlights that indigenous agricultural traditions remain a vital source of cultural and spiritual values, offering important insights for cultural preservation and locally grounded approaches to sustainable development.

This study analyzes the role of the indigenous belief system of the Dayak Tomun community as a foundation for social solidarity, a mechanism of non-formal social control, and a strategy of cultural adaptation in the context of modernization. Grounded in Émile Durkheim’s sociology of religion, particularly the concepts of mechanical solidarity and collective consciousness, this research employs a qualitative approach through a phenomenologically oriented literature review. Data were obtained from ethnographic documents, customary law manuscripts, scholarly articles, and official publications. The findings indicate that indigenous rituals, such as Babukung and Bana’i Tamu, function as means of strengthening emotional bonds and reproducing collective values through communal participation and sacred symbols. Customary law and the pamali system operate effectively as mechanisms of non-formal social control derived from supranatural authority, while simultaneously serving as strategies for ecological conservation. Indigenous beliefs also constitute the foundation of collective consciousness through the internalization of values such as mutual cooperation, respect for nature, and veneration of ancestors. Amid modernization, the Dayak Tomun community demonstrates creative adaptation through ritual reinterpretation, flexible application of pamali, and the integration of formal education with indigenous knowledge. This study affirms that the indigenous belief system of the Dayak Tomun functions as a strategic social, cultural, and ecological instrument in sustaining social cohesion, community resilience, and the continuity of collective identity in the face of contemporary social transformation.  

This study examines the relationship between Dayak cosmology and Christian spirituality through the inculturation of the Munjong tradition within Catholic Dayak Tobak communities in Dusun Batu Besi, Desa Sejotang, West Kalimantan. As a post-harvest thanksgiving ritual, Munjong embodies a symbolic framework reflecting the interconnectedness of humans, nature, ancestors, and Jebata within the Dayak worldview. The tradition functions not only as a religious expression but also as a means of preserving cultural identity and fostering social cohesion. Within a predominantly Catholic context, Munjong has undergone reinterpretation, aligning with Eucharistic spirituality as the Church’s central expression of gratitude. Using a descriptive-qualitative approach combined with symbolic interaction analysis, this study shows that the religious values embedded in Munjong, including: gratitude, petitions for protection, and veneration of ancestors as spiritual mediators, correspond with Catholic teachings on divine providence, the communion of saints, and the sacredness of creation. The local Church recognizes Munjong as a cultural practice suitable for inculturation, provided it aligns with Christian doctrine, thereby offering opportunities for contextual liturgy and catechesis. The findings suggest that Munjong can serve as a bridge between faith and local culture while simultaneously reinforcing cultural identity and deepening the spiritual life of the community. The result of this study contributes to the discourse on inculturation, contextual pastoral practice, and strategies for sustaining indigenous traditions amid social change.

This study aims to describe the structure, syntactic function, and semantic role of the nominal clause in JawaPos.com news texts published in August 2025. By using a descriptive qualitative approach, this study applied syntactic analysis to explore how the nominal clause operates within the linguistic and contextual framework of media discourse. Data were collected from online news articles and analyzed using Indonesian syntactic and semantic theory. The results show that nominal clauses play a crucial role in constructing discourse structure and meaning through their syntactic functions as subjects, objects, complements, and adverbs. In semantics, nominal clauses perform various roles, including as agents, objects, recipients, and markers of condition or location. The pattern of nominal clause use reflects the concise, efficient, and communicative nature of journalistic language. The correlation between syntactic function and semantic role shows a cohesive relationship that enhances clarity and accuracy in conveying information. This study contributes to the development of syntactic and media linguistic research and serves as a valuable reference for journalists and language educators in promoting effective and ethical language use in journalism.

Air pollution constitutes a significant environmental problem with far-reaching impacts on public health, quality of life, and ecosystem sustainability, particularly in urban areas and industrial zones in Indonesia. Although the national environmental legal framework has adopted the principle of strict liability through Law Number 32 of 2009 on Environmental Protection and Management, its implementation in air pollution cases continues to face substantial challenges, especially with regard to the proof and assessment of non-material damages. Non-material damages such as disturbances to living comfort, deterioration of environmental quality, psychological stress, and health-related anxiety are intangible in nature and lack clear measurement standards, resulting in their frequent exclusion or inadequate consideration in environmental civil litigation. This study aims to analyze the legal basis for the application of the strict liability principle to air pollution cases in Indonesia, identify relevant forms of non-material damage, and examine the implications of the absence of standardized methods for assessing such damages on legal certainty and the effectiveness of corporate liability enforcement. The research employs a normative legal research method with a library-based approach, incorporating statutory, conceptual, and case approaches. Legal materials are analyzed qualitatively using a descriptive-analytical method, drawing upon legislation, court decisions, and scholarly literature on environmental law and environmental damage valuation. The findings indicate that the absence of standardized criteria for assessing non-material damages leads to evidentiary difficulties, inconsistent court decisions, and a weakened deterrent effect on polluting corporations, thereby preventing the full realization of victims’ rights to effective remedies. This study underscores the urgency of developing an integrated national technical guideline for the assessment of non-material environmental damages based on scientifically grounded valuation methods, as well as the need for cross-institutional policy harmonization to strengthen legal certainty, access to justice for affected communities, and corporate accountability in controlling air pollution.

Gununganyar Reservoir in Tuban Regency is one of the reservoirs used as a source of livelihood for the local community. However, further development and utilization of Gununganyar Reservoir have yet to be undertaken. The development of a small-scale floating Photovoltaic Solar Power Plant (floating solar panels) at Gununganyar Reservoir, aimed at providing an alternative and renewable energy source for operating raw water pumps and for supporting the Gununganyar Nature Tourism (WAG) initiative, constitutes an innovative and strategic effort to enhance energy efficiency and environmental sustainability in rural areas. This study focuses on the design and performance assessment of a floating solar panel system constructed with processed bamboo as an alternative floating material replacing HDPE, while integrating local wisdom and environmental conservation principles to minimize the reservoir’s carbon footprint. The methodology employs a simple quantitative approach combined with a literature review of relevant studies. Based on the analysis, the design of this small-scale floating solar panel system utilizes a 170 Wp off-grid solar module mounted at a tilt angle of approximately 7,1°, capable of generating a peak power output exceeding 2,962 kWp and supported by a battery capacity of  328,33 Ah. The implementation of these floating solar panels is expected to serve as a model for reservoir development by promoting energy self-sufficiency, stimulating local economic growth, and contributing to the achievement of net zero emissions by 2060.

This study aims to examine the role of the Village Government in enforcing customary law sanctions of Wake Uru Sorong Tada and to analyze the effectiveness of its implementation in Heo Puat Village, Hewokloang District, Sikka Regency. Wake Uru Sorong Tada is a form of customary law that functions as a traditional prohibition to regulate and protect community ownership of agricultural products and commodities. This research employs a qualitative descriptive method. Data were collected through observation, in-depth interviews, and documentation involving key informants such as the village head, Village Consultative Body members, traditional leaders, and community members. Data analysis was conducted using the interactive model proposed by Miles and Huberman, which includes data reduction, data display, and conclusion drawing. The findings reveal that the Heo Puat Village Government plays an active role as a facilitator, mediator, and guarantor in enforcing customary sanctions in accordance with Village Regulation Number 2 of 2009. The village government does not directly determine the sanctions but collaborates closely with customary institutions in resolving violations. The enforcement of Wake Uru Sorong Tada customary law sanctions is considered effective in maintaining social order, security, and a sense of safety in property ownership among community members. The strict and binding nature of customary sanctions has significantly increased legal awareness and minimized social conflicts within the village.

Corporate Social Responsibility (CSR) in Indonesia has undergone a paradigmatic shift from voluntary philanthropic activities to a legally binding obligation grounded in various statutory regulations, particularly Law Number 40 of 2007 on Limited Liability Companies and Law Number 25 of 2007 on Investment. This study aims to analyze the legal framework governing CSR in Indonesia from a public policy perspective, to evaluate the implementation of CSR by corporations, and to identify normative and empirical constraints that hinder the optimization of CSR as an instrument of sustainable development. The research employs a normative juridical method with statutory, conceptual, case-based, and policy analysis approaches. The findings indicate that CSR regulation remains partial in nature, primarily due to the limitation of mandatory obligations to specific sectors, the absence of clear and enforceable sanctions, and the lack of national standards for reporting and oversight.

A moral crisis occurs when a person loses the attitude, character, and behavior that are in accordance with goodness. Moral and ethical crises often occur among the younger generation in Indonesia due to various factors, such as the impact of globalization, the influence of social media, the lack of parental involvement, and the lack of character education in schools. This study aims to explore the relevance of character education values in M. Quraish Shihab's Tafsir Al-Mishbah to the problems faced by students in the contemporary era. The crisis of morality, bullying, and the threat of radicalism are the background to the urgency of internalizing contextual Qur'anic values. This research is qualitative in nature, using library research, a thematic approach, and content analysis. The results show that the concept of character education in Tafsir Al-Mishbah is rooted in the relationship between the meaning of Rabb and tarbiyah, which aims to shape Insan Kamil through intellectual and spiritual balance. Analysis of Q.S. Luqman: 12-13, Q.S. Al-Hujurat: 11-13, and Q.S. Al-Mujadilah: 11 reveals fundamental values such as monotheism, gratitude, tolerance, and manners in seeking knowledge. The relevance of the findings shows that Quraish Shihab's moderate (wasathiyah) thinking is very effective in protecting students from extreme ideas, building digital literacy ethics through the principle of tabayyun, and eliminating the culture of violence in schools through a humanistic approach. This study concludes that Tafsir Al-Mishbah offers a functional methodological framework for strengthening the character of 21st-century students.

Plastic waste has become one of the main environmental problems due to its nature, which is difficult to decompose naturally and can cause environmental pollution. One alternative waste treatment method that can be applied is to use a plastic melter to melt and recycle plastic waste into useful products. However, the design of plastic melters often lacks consideration of structural strength and safety aspects during the operation process. This study aims to design and engineer a plastic melter using the Finite Element Analysis (FEA) simulation approach to analyze structural resistance to thermal and mechanical loads that occur during the operation process. The research method was carried out through 3D design modeling of plastic melter components using Solidworks software, followed by analysis with FEA simulation on the main component, namely the melting tube. The parameters analyzed include the distribution of von Mises stress, the amount of displacement, and the safety factor. The analysis results show that the analyzed components experience von Mises stress distribution and displacement that are still below the material tolerance limits, with safety factor values above the recommended safety limits. Thus, the resulting plastic melter design is declared safe and can proceed to the manufacturing process. Therefore, the plastic melter design is safe, strong, and feasible to be realized as an effective and sustainable plastic waste processing technology solution.

Teaching plane geometry often faces challenges due to the abstract nature of geometric concepts, which are often detached from students’ real-life contexts. This study is a development research (Research and Development) using a modified 4D model reduced to 3D (Define, Design, Develop) aimed at producing and testing the validity of a Student Worksheet based on ethnomathematics with Batik Sekundang motifs on plane geometry material oriented toward Contextual Teaching and Learning (CTL). Validation was conducted by two mathematics education experts who assessed the feasibility of content/material, media, and language/readability using a Likert scale instrument. The data were analyzed quantitatively in a descriptive manner using percentage formulas to determine the level of validity. The results showed that the student worksheet obtained a validity percentage of 87.50% in content feasibility (very valid), 80.76% in media (valid), and 87.50% in language (very valid), with an overall average of 85.25%, which falls into the very valid category. Based on these results, the ethnomathematics-based student worksheet with Batik Sekundang motifs is declared suitable to be used as a supporting teaching material for contextual and meaningful plane geometry learning for students in South Bengkulu.

Learning geometric transformations requires a strong conceptual understanding due to their abstract nature. One effort to enhance students’ conceptual understanding of mathematics is through the development of contextual and meaningful instructional materials that incorporate local culture. This study is a research and development (R&D) study employing the 4D model (Define, Design, Develop, and Disseminate) aimed at examining the validity of the developed Student Worksheets. The validation of the Student Worksheets was conducted by two experts in mathematics education who evaluated the aspects of content feasibility, media, and language and readability. The data were analyzed using descriptive quantitative methods with percentage scores to determine the level of validity of the Student Worksheets. The results showed that the developed Student Worksheets obtained a validity percentage of 93.75% for the content feasibility aspect (very valid), 80.77% for the media aspect (valid), and 87.50% for the language and readability aspect (very valid), with an overall average of 87.34%, which falls into the very valid category. Based on these results, the ethnomathematics-based Student Worksheets using the Kepahiang Traditional House context are considered feasible for use as supporting instructional materials in learning geometric transformations.

Surveillance for diarrhea at the district level in Indonesia is still affected by the fragmented nature of the District Health Information System (DHIS) and Early Warning and Response System (EWARS), inconsistent reporting, patchy data interoperability, and the resulting public health delays. Although there are systems in place like the DHIS and EWARS, the persistent use of hybrid systems that combine manual and digital data entry, as well as the different skill levels of users, continues to produce issues of incompleteness, untimely reporting, and inaccurate data. The present study investigated the deficiencies in surveillance reporting of diarrhea cases, the surveillance data to determine the degree of integration and also investigated the health workers perceptions of the barriers to effective reporting. A mixed methods approach was adopted in this study where we investigated quantitatively the DHIS and routine diarrhea reports submitted for the entire year of 2023, and combined that with qualitative, in-depth interviews with the relevant surveillance officers, program managers, and district staff. The quantitative analysis indicated gaps in reporting about 55% in terms of completeness, and consistency of reporting and also significant differences were found between the manual register, DHIS, and EWARS whereby the integration of these systems was found to be low. The qualitative analysis pointed to the combination of disconnected workflows, limited cross-system interoperability, inadequate system training, excessive workloads, and weak organizational feedback, as the main barriers to effective reporting. The combination of these two datasets illustrates the fact that both system deficiencies and organizational factors are primary drivers of the reporting. Closing the gaps will require system level changes in the interoperability of reporting systems, simplified reporting workflows, training, reporting, and reporting feedback loops.

This study aims to describe the implementation of ethical philosophy learning and the assessment pattern for student learning outcomes at the KH. Ahmad Sanusi Sukabumi Institute (INKHAS). Ethical philosophy is understood as a critical study of good and bad values in human actions, which not only accepts moral teachings normatively, but examines them rationally and in depth. In the learning process, this course applies discussion and dialogue methods as the main approach to encourage students to think critically, express opinions argumentatively, and build mutual respect. The lecturer acts as a facilitator who directs the discussion, instills academic ethics, and maintains a scientific learning flow. The assessment pattern does not focus on memorizing theories, but rather on students' analytical abilities as measured through discussion participation, individual assignments, and group assignments. The results of the study indicate that this method is effective in developing students' conceptual understanding, critical thinking skills, and moral awareness, although obstacles such as lack of motivation in some students due to the abstract nature of the material are still found. Overall, ethical philosophy learning at INKHAS plays an important role in shaping ethical character, reflective thinking, and responsible attitudes in academic and social life.

The concept of human nature occupies a fundamental position in the philosophy of Islamic education, as it serves as the foundation for formulating educational goals, curriculum design, teaching methods, and the overall direction of education. Islamic education is not merely oriented toward the transfer of knowledge but is directed toward shaping the whole human being in a balanced manner, encompassing physical, intellectual, and spiritual dimensions. This study aims to examine the concept of human nature from the Islamic perspective and the views of Islamic philosophical figures, as well as to analyze its philosophical and practical implications for the implementation of Islamic education. This research employs a library research method by reviewing primary and secondary sources, including the Qur’an, classical Islamic texts, and relevant scholarly literature on human nature and Islamic education. The findings indicate that Islam views human beings as multidimensional creatures endowed with fitrah, intellect, spirituality, and social responsibility as servants and vicegerents of God on earth. The Qur’anic concepts of humanity, reflected in the terms al-insān, al-basyar, and al-nās, emphasize the complexity and uniqueness of humans as biological, rational, spiritual, and social beings. The perspectives of scholars such as Al-Ghazali, Ibn Arabi, and Hasan Al-Banna further reinforce the view that Islamic education must integrate intellectual, moral, and spiritual development in a balanced manner. The implications of this study highlight the necessity of designing Islamic education in a holistic and humanistic framework to produce insan kamil—individuals who are faithful, knowledgeable, possess noble character, and demonstrate social responsibility in communal life.

Nature-based tourism development has a strategic role in encouraging sustainable local economic growth, especially in rural areas such as Marente Village, Kabupaten Sumbawa. Agal Waterfall is one of the natural tourism destinations that has high attractiveness, but its utilization is still not optimal due to limited facilities and infrastructure, access to the location, promotional activities, and the quality of human resources management. This study aims to identify strengths, weaknesses, opportunities, and threats, and determine priority strategies in developing Agal Waterfall tourism using the Quantitative Strategic Planning Matrix (QSPM) method. The research approach used is descriptive quantitative with primary data collected from 100 respondents. Analysis techniques include the preparation of IFAS, EFAS, SWOT, and QSPM matrices. The research findings show that the beauty of the natural environment and community participation are the main strengths, while the limited supporting facilities and promotion are still the dominant weaknesses. Development opportunities are supported by the increasing interest in nature tourism and the utilization of digital platforms, while threats come from competition between tourist destinations and the potential for environmental degradation. Based on the results of the analysis, priority strategies suggested include improving basic facilities, optimizing digital-based promotions, strengthening the capacity of human resource managers, and implementing the principles of sustainable tourism.

This study examines the effect of Environmental, Social, and Governance (ESG) ratings on firm performance and the moderating role of ESG rating disagreement within the Indonesian capital market. Using a panel dataset of 63 companies listed on the Indonesia Stock Exchange from 2021 to 2023 and employing a fixed-effects regression model, the analysis measures firm performance with Tobin’s Q, ESG ratings from Refinitiv Eikon, and ESG rating disagreement as the standard deviation between Refinitiv and Bloomberg scores. The empirical results indicate that ESG ratings do not have a statis-tically significant effect on firm performance, and ESG rating disagreement does not significantly moderate this relationship. These findings suggest that ESG-related information has not yet been fully internalized into firm valuation in Indonesia, with current ESG practices perceived as largely symbolic rather than substantively integrated into corporate strategy. The study concludes that both ESG ratings and rating disagreement fail to serve as effective mechanisms for enhancing firm performance in the Indonesian context, reflecting the early-stage development and compliance-driven nature of ESG adoption in emerging markets.
