Flooding remains a recurrent hazard in the Special Capital Region of Jakarta (DKI Jakarta), causing substantial disruptions across multiple dimensions community life, including social well-being and economic activities. The availability of flood-related information through the Jakarta One Data Portal (Satu Data Jakarta) provides significant opportunities for broader data utilization; however, transforming such information into meaningful assessments regional vulnerability requires a systematic analytical approach to generate more comprehensive understanding of the conditions of individual urban villages (kelurahan). This study focuses on the classification areas based on the characteristics and impacts of flood events occurring throughout DKI Jakarta. The analysis utilizes flood event records from 2023 to 2025 and incorporates several indicators, including the number of flood occurrences, the number of affected neighborhood associations (RW), the number affected households, the number of affected residents, the number of evacuees, the number of evacuation sites, and floodwater depth. Data processing was conducted using the Knowledge Discovery in Databases (KDD) framework, encompassing data selection, cleaning and preprocessing, transformation, pattern exploration, result evaluation, and knowledge extraction. The findings demonstrate that three-cluster solution effectively captures variations in flood vulnerability levels, corresponding to low-, moderate-, and high-risk categories. A total of 96 urban villages were classified as low-risk, 27 as moderate-risk, and 46 as high-risk areas. The resulting clustering patterns provide a clearer spatial representation of flood-risk distribution across urban villages, thereby offering valuable insights for the development more targeted mitigation strategies, the prioritization of flood management interventions, and the enhancement of evidence-based decision-making processes in DKI Jakarta.

Limited land availability is a major constraint in developing school infrastructure in active urban educational facilities. This study evaluates the classroom development plan at SDN 39 Lubuklinggau from the perspective of a planner, focusing on land limitation, functional needs, safety, constructability, and long-term building performance. A descriptive-evaluative approach was applied through technical observation, document review, alternative assessment, weighted scoring, and risk analysis. The results indicate that horizontal expansion is constrained by limited open space and may reduce internal circulation, student activity areas, and emergency space. Three alternatives were compared: horizontal expansion, building rearrangement, and a two-storey classroom scheme. The two-storey alternative obtained the highest score of 84, compared with 61 for rearrangement and 56 for horizontal expansion. However, its feasibility depends on further soil investigation, structural design, staircase and evacuation safety, utility coordination, construction phasing, and strict site safety control. The study recommends that the planner prioritize detailed site measurement, geotechnical investigation, detailed engineering design, construction safety planning, and post-construction functional evaluation. A vertical classroom strategy can be considered a rational solution for land-constrained schools when supported by accountable technical planning and integrated project control.

The development of the internet and social media has encouraged e-commerce companies to utilize digital platforms as a marketing tool, one of which is Shopee through TikTok social media.

The results of this study indicate that cognitive levels C4-C6 in the Revised Bloom's Taxonomy serve as the primary reference in developing HOTS instruments, which can assist in developing HOTS-based instruments to measure students' higher-order thinking skills.

This study aims to analyze the impact of nickel mining activities on the religious life of the community in West Kabaena District, Bombana Regency. The research employed a qualitative method with a descriptive approach to obtain an in-depth understanding of the social and religious changes occurring within the community. Data were collected through interviews, observations, and documentation involving religious leaders, community leaders, youth representatives, and mining workers. The collected data were analyzed through data reduction, data display, and conclusion drawing. The findings indicate that nickel mining activities have not diminished the community’s understanding of environmental stewardship as a religious responsibility. However, increasing economic dependence on the mining sector has gradually reduced public concern for environmental preservation. In the religious sphere, mining activities have contributed positively by supporting the construction and improvement of worship facilities and religious programs. Nevertheless, work-related demands have reduced the participation of some community members in religious activities. Furthermore, mining activities have affected social solidarity within the community. Values such as brotherhood, mutual cooperation, and social care remain preserved, although changes in social interaction patterns and widening economic disparities have become increasingly apparent. The study concludes that nickel mining activities generate both positive and negative impacts on the religious life of the West Kabaena community. Therefore, balanced policies integrating economic development, environmental sustainability, and religious values are essential to promote sustainable community welfare and strengthen social harmony.

The urgency of this research stems from the knowledge gap regarding contextual factors contributing to the underuse of learning media in rural elementary schools, which has not been adequately addressed in previous research, which has tended to focus on urban contexts. This study aims to examine teachers' perceptions at Sugayang Public Elementary School regarding the underuse of learning media in the learning process, as well as the factors that contribute to it. The method used was a descriptive qualitative method, utilizing in-depth interviews as a data collection technique. The data were then analyzed using data reduction, data display, and conclusion drawing techniques according to Miles and Huberman. The results showed that teachers experienced difficulties in using technology, difficulties in creating learning media, and the perception that using media was time-consuming. This reveals an important pattern that the underuse of learning media is a systematic problem rooted in the TPACK gap that is not supported by practical time management solutions. These findings imply that changes in learning practices will not occur simply through the provision of generic technology tools or training; rather, bottom-up and contextual solutions are needed. The novelty of this research lies in the in-depth qualitative approach applied to the under-researched context of rural elementary schools, which has not been studied before. This research contributes through recommendations for the implementation of a peer-mentoring program and the development of a ready-to-use digital learning media bank, thus offering valuable insights for future research with relevant stakeholders.

This study investigates the role of Baitul Maal wa Tamwil (BMT) in empowering Micro, Small, and Medium Enterprises (MSMEs) through the integration of Maqashid Sharia principles and financial inclusion strategies. Despite the strategic importance of MSMEs in economic growth and poverty reduction, many face challenges in accessing formal financial services. BMT, with its dual function of social (maal) and commercial (tamwil) activities, offers a unique platform to bridge this gap. Using a qualitative systematic literature review guided by PRISMA, this study analyzes 30 relevant articles to examine BMT operational models, implementation of Maqashid Sharia objectives, financial inclusion practices, and their impact on MSME performance. Findings indicate that BMT effectively supports MSMEs in capital access, income generation, and business resilience, but inconsistencies in balancing social and commercial objectives limit. holistic empowerment. Integrating Maqashid Sharia principles enhances ethical and sustainable outcomes, while financial inclusion expands outreach to underserved entrepreneurs. Optimization strategies, including strengthening institutional capacity, combining financial and non-financial support, and context-specific interventions, are essential for maximizing BMT effectiveness. This study contributes a comprehensive framework linking ethical, financial, and empowerment dimensions, offering practical guidance for policymakers and BMT managers in promoting inclusive and sustainable MSME development.

This study aims to provide the benefits of a psychological approach in education through a learning adjustment strategy based on the developmental stage and age limits of students. The study used a library method with a qualitative descriptive-analytical approach through a review of educational psychology literature, cognitive development theory, national education regulations, and various relevant scientific journals. The results of the study indicate that learning effectiveness is greatly influenced by the alignment between material, teaching methods, and students' psychological readiness. Piaget's cognitive development theory indicates that elementary school-aged children are at the concrete operational stage, thus requiring contextual learning, the use of real-life media, and active interaction in the learning process. This study also found that age limits in the education system have an important function as a means of synchronizing students' biological, emotional, social, and intellectual readiness with learning targets. Through the "Psychological Navigation" model, this study offers a strategic framework for educators to create adaptive, humanistic learning that is oriented towards optimal student development. The implications of this study emphasize that teachers need to understand the individual characteristics of students so that the educational process does not only focus on academic achievement, but also supports the psychological well-being and character formation of students as a whole.

This research investigates the integration of Sound Governance principles within the sustainable tourism policy cycle as a mechanism to mitigate institutional fragmentation and evaluation inefficiencies in developing economies. Adopting a sequential explanatory mixed-methods design, the study establishes a multidimensional evaluation framework congruent with the Sustainable Development Goals (SDGs). Policy performance is rigorously analyzed across five strategic domains: Economy, Social-Welfare, Culture-Education, Environment, and Governance. The quantitative methodology employs 17 adapted SDG indicators to assess policy efficacy, while the subsequent qualitative phase utilizes semi-structured interviews and stakeholder mapping to deconstruct complex power dynamics within multi-actor co-management structures. The empirical findings demonstrate that Sound Governance—predicated on transparency and accountability—acts as a fundamental catalyst for policy effectiveness. It significantly enhances destination sustainability through a structured input-process-output-outcome-impact pathway. Evidence from the case study of Penglipuran Village, Bali, validates these results, showing that while indigenous institutional legitimacy bolsters social responsiveness, it remains susceptible to economic dependencies driven by overtourism. Ultimately, this study asserts that embedding SDGs into the policy evaluation cycle elevates assessments from perfunctory administrative exercises to strategic instruments essential for ecosystem preservation and long-term demand stability. These insights establish Sound Governance as a strategic intangible asset, providing significant theoretical contributions to development administration and offering pragmatic frameworks for policy-makers managing sustainable destinations in competitive global markets.

The drainage system is critical infrastructure for managing stormwater runoff in densely built urban areas, including higher education institutions. This study aims to evaluate the capacity performance of the existing drainage channels in the UPN "Veteran" Jawa Timur campus area. The evaluation was conducted through two main stages: hydrological analysis using the rational method to estimate the design runoff discharge for a 10-year return period, and hydraulic analysis using Manning's equation to calculate the channel cross-sectional capacity in accordance with Permen PU No. 12 of 2014. Based on the assessment of 43 drainage channels, the results showed that 33 channels (76.7%) are still functioning optimally and capable of accommodating the design discharge. Conversely, 10 channels (23.3%) were identified as having insufficient capacity. This capacity deficit was triggered by initial designs that did not accommodate the 10-year return period flood discharge, increased runoff coefficients due to massive pavement development, and effective cross-section narrowing caused by sedimentation. To mitigate inundation issues, this study recommends redesigning the failing channels using an economical hydraulic cross-section, accompanied by periodic normalization and dredging for functional channels. The findings of this study are expected to serve as technical guidelines for the optimal and sustainable management of campus drainage infrastructure.

Sharia financial literacy is an important aspect in supporting inclusive and sustainable economic development. However, the level of sharia financial literacy among Indonesian society is still relatively low. This condition creates opportunities for Islamic boarding schools (pesantren) to play a strategic role in improving young generations’ understanding of financial management based on sharia principles. Therefore, this community service activity aimed to enhance the sharia financial literacy and inclusion of students through the SAKINAH (Santri Cakap Literasi Keuangan Syariah) Program at Nurul Abshor Islamic Boarding School, Katingan Regency. The program was implemented using a participatory educational approach through socialization, interactive discussions, simple simulations, and participant evaluations. The activity was carried out through collaboration among the Financial Services Authority (OJK) of Central Kalimantan Province, the Islamic Economic Society of Katingan Regency, PT Bank Syariah Indonesia Palangka Raya, Nurul Abshor Islamic Boarding School, the Regional Financial Access Acceleration Team of Katingan Regency, and students of Palangka Raya University. The results showed an improvement in students’ understanding of the importance of saving, the ability to distinguish between needs and wants, sharia financial management, and knowledge of legal and trustworthy sharia financial products and services. The SAKINAH Program was also considered effective in encouraging students to become agents of sharia financial literacy within the pesantren environment and the wider community.

This study aims to analyze the effect of the Open Unemployment Rate (OUR), Human Development Index (HDI), and zakat on poverty in Mandailing Natal Regency. The study employed a quantitative approach using the Vector Error Correction Model (VECM) based on quarterly secondary data from 2015 to 2025. The analytical procedures included stationarity testing, optimal lag selection, Johansen cointegration testing, VECM estimation, Granger causality testing, as well as Impulse Response Function (IRF) and Variance Decomposition (VD) analyses. The findings indicate that all variables were stationary at the second difference level, with an optimal lag length of four, and exhibited a long-run cointegration relationship. The VECM estimation reveals that, in the long run, the Open Unemployment Rate has a positive and significant effect on poverty, while zakat has a negative and significant effect in reducing poverty. In contrast, the Human Development Index does not significantly affect poverty, which may be explained by the presence of a development time lag and employment mismatch between workforce competencies and labor market demands. The Granger causality test indicates a one-way causal relationship from the Open Unemployment Rate to the Human Development Index. Furthermore, the Variance Decomposition analysis shows that poverty variation is predominantly explained by its own shocks (96.25%), reflecting the persistence of structural poverty. Therefore, policy synergy through employment expansion and the optimization of productive zakat programs based on business empowerment is recommended to accelerate poverty alleviation in Mandailing Natal Regency.

The development and performance of high-strength, environmentally friendly, and renewable nunang fiber (Cordia dichotoma)-reinforced polyester composites continue to be refined to achieve optimal performance. This study characterizes the key properties of nunang fiber-reinforced polyester composites with carbon powder fillers. The polyester composites were fabricated using a hot-press method with a nunang fiber volume fraction of 20% (by weight) and varying carbon powder content from 0–10% (by weight). The results of the investigation show that the tensile and bending strengths of the composites increase with increasing carbon powder content up to 2.5%. However, adding carbon powder filler up to 10% to the polyester–nunang fiber composites reduces their tensile and bending strengths. A different trend is observed for the impact toughness of the composites, which increases up to a carbon powder content of 5% and decreases when the carbon powder content reaches 10%. This phenomenon is attributed to the ability to form an optimal fiber-matrix interface between the nunang fibers and the polyester–carbon powder matrix. SEM morphological observations confirmed fiber pull-out failure and matrix failure due to the high stiffness caused by the presence of the carbon powder filler.
