Abstract:The conflict surrounding the Rempang Eco-City National Strategic Project (PSN) on Rempang Island, Batam City, Riau Islands Province, is one of the most complex development policy crises of the past decade. This study analyzes…
lyzes the neglected environmental disaster mitigation dimensions in the acceleration of the Rempang Eco-City PSN from nine environmental perspectives, while evaluating whether the cancellation of this strategic development policy is a normatively and empirically justifiable choice. Using a qualitative research approach with a case study design, the study combines regulatory analysis based on legal documents including Laws, Government Regulations, Presidential Regulations, Ministerial Regulations, Environmental Impact Assessment (AMDAL) documents, and the Batam City Spatial Plan (RTRW) with field data from secondary sources compiled between 2023–2025. The findings reveal four main conclusions: (1) regulatory incoherence exists between Permenko Ekuin No. 7/2023 and Law No. 32/2009 on Environmental Protection and Management (PPLH) as well as Law No. 27/2007 on Coastal Zone Management; (2) the AMDAL process was carried out procedurally without participatory substance and was only initiated after the conflict erupted; (3) environmental impacts including threats of deforestation of protected forests, mangrove ecosystem degradation, and sea sand exploitation have not been adequately mitigated; and (4) resistance from approximately 80% of affected residents indicates a failure of the Free, Prior, and Informed Consent (FPIC) principle. The most recent development shows that through Presidential Regulation (Perpres) No. 12 of 2025, signed by President Prabowo Subianto on February 10, 2025, Rempang Eco-City is no longer listed among the 77 national strategic projects. This study recommends a comprehensive policy evaluation for Rempang Island development based on an independent AMDAL review, fulfillment of the rights of the Malay indigenous community, and a moratorium on all construction activities until legal certainty is established.

od with a case study design and library research, this study examines five main dimensions: the chronology of the Rempang Island case, policy conflicts and controversies, the government regulatory framework, disaster risk analysis from nine environmental perspectives, and overall policy evaluation. The findings reveal that the Rempang Eco City project, designated as a National Strategic Project (PSN) through Permenko for Economic Affairs Number 7 of 2023, triggered prolonged agrarian conflict due to the absence of meaningful participation from indigenous Malay communities who have inhabited 16 ancient villages on the island since 1834. The project implementation was marked by forced evictions, repeated acts of violence, and non-transparent environmental impact assessment (AMDAL) processes. Disaster risk analysis from nine environmental perspectives covering air quality, water quality, coastal and marine ecosystems, sand mining and geological degradation, biodiversity, community health, social-cultural impacts, climate change vulnerability, and environmental governance consistently produces high-risk assessments, affirming that Rempang Island as a small island ecosystem lacks adequate carrying capacity for large-scale glass industrial development without permanent and irreversible ecological damage. Although Presidential Regulation Number 12 of 2025 de facto removed Rempang Eco City from the list of 77 National Strategic Projects under President Prabowo Subianto’s administration, the absence of an explicit revocation of Permenko Number 7 of 2023 creates ongoing legal ambiguity for affected communities. This research concludes that Indonesia urgently requires fundamental reform in its investment-based development policy paradigm, encompassing strengthened indigenous community participation mechanisms, elevation of AMDAL as a non-circumventable legal requirement prior to investment designation, and application of the ecological precautionary principle in small island development.

atant cultures derived from mouse cell immunoglobulin hybridization. Examination of blood type with serum is an examination that uses blood type A as anti-B, blood type B as anti-A, and blood type O as anti-AB. The purpose of this study was to determine the profile of the ABO system blood group examination using antisera reagents and serum slide method. The research method used was descriptive with samples of the ABO system blood group using antisera and serum reagents for 30 respondents using probability sampling technique. The materials used are human blood groups A, B, AB and O and anti-A, anti-B, anti-AB reagents. Data analysis was descriptive in the form of a profile table of the results of the ABO system blood group examination using antisera and serum reagents. The results of the study revealed that the results of blood group A were 7 (23%), blood group B were 7 (23%), blood group AB were 8 (27%), and blood group O were 8 (27%). The results obtained showed that the antisera and serum reagents had differences in the blood group examination results, namely the grade of agglutination produced by the serum was different from that of the antisera. It can be concluded that the results of blood grouping with antisera and serum reagents can be used for blood group examination. However, compared to antisera reagents, the results are better using antisera reagents compared to serum.
Abstract:In the era of artificial intelligence (AI), the rise of pornographic deepfakes poses a serious threat to human dignity, privacy, and social stability. This phenomenon exploits deep learning technology to manipulate individuals’…
iduals’ faces into non-consensual pornographic content, often targeting women and public figures. This paper examines the ethics of Ibn Miskawayh, a 10th-century Muslim philosopher, specifically the concept of hifz al-nasl (preservation of lineage) as one of the five maqasid al-shari’a (Islamic principles), to address this issue. Hifz al-nasl emphasizes the protection of human lineage, including family honor, women’s dignity, and social integrity, which are relevant to the psychological damage, trauma, and moral degradation caused by deepfakes. Through an analysis of the texts Tahdhib al-Akhlaq and Al-Fauz al-Asghar, this concept is outlined as a preventive and curative principle: prevention through strengthening individual morals and regulating technology, and treatment through restorative justice. Ibn Miskawayh combines Aristotelian philosophy with Islam, making hifz al-nasl a collective obligation to maintain the balance of the soul (nafs) and society. Its applications to deepfakes include: (1) ethical use of AI based on piety and ‘adl; (2) legal regulations that protect privacy as an extension of preserving lineage; and (3) moral education to build digital resilience. This study concludes that Ibn Miskawaih’s approach offers a holistic framework, integrating spiritual, ethical, and legal dimensions, that is more adaptive than technological solutions alone. Recommendations include the development of contemporary fatwas and ethical AI platforms for the digital age.

Abstract:This study aims to develop Islamic Religious Education (IRE) teaching materials in the element of Aqidah and Akhlak based on religious moderation for eleventh-grade high school students. The background of this research lies…
ies in the limited availability of teaching materials that systematically integrate religious moderation values, whereas such values are crucial in shaping students’ character to become faithful, virtuous, and tolerant individuals in a pluralistic society. The research method employed is Research and Development (R&D), adopting the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The subjects of the trial involved material experts, media experts, Islamic Education teachers, and grade XI students. The research instruments included validation questionnaires, practicality questionnaires, and learning achievement tests. The collected data were analyzed using both quantitative descriptive and qualitative methods. The results indicate that the developed IRE teaching materials based on religious moderation are highly valid, with an average validity percentage of 89.58%. In terms of practicality, both teachers and students responded positively, categorizing the product as very practical and easy to use in the learning process. Regarding effectiveness, the use of these teaching materials successfully improved students’ learning outcomes, shown by the N-Gain score categorized as moderate, with 100% learning mastery achieved during the field trial. Therefore, this development contributes significantly to providing relevant, innovative, and contextual teaching media. The teaching materials not only facilitate cognitive competency achievement but also instill the values of religious moderation oriented toward strengthening faith, cultivating morality, and fostering tolerance, justice, and balance. This study is expected to serve as an alternative solution for curriculum development in Islamic Religious Education at the secondary level and as a reference for teachers in creating more meaningful learning

an exploratory case study design, focusing on the subjective experiences of both Islamic Education teachers and students regarding the application of love-based values in Islamic Education. Data were collected through semi-structured interviews, classroom observations, and document analysis, involving Islamic Education teachers and students from various grade levels. The findings indicate that the Love-Based Islamic Education Curriculum significantly enhances students' discipline, empathy, and social interaction. Storytelling and self-reflection methods were found to be effective in helping students internalize the values of love towards Allah, the Prophet, fellow humans, and nature. However, key challenges identified include the limited availability of relevant teaching materials and students' difficulties in applying love values outside the classroom. The study also highlights the importance of parental and community involvement in supporting the implementation of the Love-Based Islamic Education Curriculum beyond the school environment. The research recommends the development of more applicable teaching materials, ongoing teacher training, and stronger collaboration with parents to reinforce the values of love in students' daily lives. This study contributes significantly to the development of love-based curricula in Indonesian private schools.
Abstract:The global demand for energy continues to increase alongside population growth and rapid industrial development, while dependence on fossil fuels remains high. This presents challenges related to environmental degradation,…
n, carbon emissions, and concerns over long-term energy availability. Biomass-based alternative energy has emerged as one of the strategic solutions to support sustainable energy transitions, particularly in developing countries such as Indonesia. One potential biomass source that remains underutilized is horse manure, which can be processed into briquettes known as Brikuda.
This study aims to analyze the potential of Brikuda as an alternative energy source and to develop a sustainable business model using the Business Model Canvas (BMC). A qualitative descriptive approach was employed, involving in-depth interviews, direct observations, and analysis of secondary data. The findings reveal that Brikuda has strong potential as a renewable fuel due to the abundant availability of horse manure in Bandar Lampung. It offers economic benefits, reduces environmental pollution, and supports local empowerment. The Business Model Canvas analysis shows that farmers and livestock breeders are the primary customer segments, while the value proposition emphasizes affordability, environmental friendliness, and ease of use.
The study concludes that the Brikuda business model can enhance local economic value, promote sustainable waste management, and serve as a feasible alternative energy innovation. The research contributes to the development of renewable energy entrepreneurship and provides a reference for policy formulation in promoting local-based bioenergy initiatives.
Abstract:This study investigates the tensile uplift capacity of screw piles in clay soil as an alternative anchoring system for slope stabilization in cohesive ground conditions. The research aims to address the limited availability…
ity of empirical field data on screw-pile behavior under repeated loading and to evaluate the agreement between theoretical predictions and actual in situ responses. The methodology employs an experimental approach through in situ testing with screw-pile diameters of 10 cm, 15 cm, and 20 cm, and embedment depths ranging from 0.6 m to 1.0 m. The tests were conducted under both static and repeated tensile loading using a hydraulic jack system, accompanied by vertical deformation measurements to establish load–displacement curves. Theoretical capacity was calculated using a limit equilibrium approach for comparison with experimental results. The findings reveal a nonlinear load–displacement response, characterized by initial stiffness followed by progressive deformation into the post-yield stage. At a maximum load of 2.858 tons, deformation increased with diameter, from 5.10 cm (10 cm) to 8.49 cm (20 cm). Under repeated loading, failure occurred at a lower load of approximately 1.6 tons with a maximum deformation of 1.648 cm, indicating potential capacity degradation due to cyclic loading. The comparison between theoretical and field results shows significant deviations, with analytical predictions generally underestimating the in situ capacity. This highlights the limitations of simplified models that do not fully account for shaft adhesion, installation disturbance, soil heterogeneity, pore-water pressure effects, and cyclic degradation. Overall, this study contributes valuable field pull-out test data for screw piles in clay under repeated loading, emphasizing the need for design calibration based on full-scale testing for slope stabilization applications. The results also suggest opportunities for further research involving long-term monitoring and advanced modeling of cyclic degradation.
