Rainfall plays a crucial role in determining flood risk, particularly in regions with high precipitation intensity and limited drainage capacity. Langkat Regency in North Sumatra is one of the areas frequently affected by seasonal flooding. This study aims to model the spatial distribution of rainfall and estimate the rainwater volume using the double integral approach as a basis for flood mitigation planning. Monthly rainfall data from various observation stations in 2024 were processed to obtain the average rainfall intensity, which was then converted into meters and multiplied by the total area of Langkat Regency to compute the rainwater volume. The results indicate that the total estimated rainwater volume throughout 2024 reached 16,409,819,800 m³, with peak precipitation occurring from September to November, contributing significantly to the increasing flood risk in low‐lying zones and riverine areas. These findings demonstrate that the use of double integrals is an effective quantitative method for predicting potential flood volume based on rainfall distribution. The outcomes of this study are expected to serve as a scientific reference for local governments in developing data-driven flood mitigation strategies, such as improving drainage capacity, constructing retention basins, and strengthening watershed management.

The increasing integration of digital technology into the daily lives of Generation Alpha has contributed to reduced physical activity, highlighting the need to understand the factors shaping children’s movement behaviors. This study employed a quantitative correlational approach to examine the relationship between parental educational background and the physical activity levels of students aged 13–15 at SMP 1 Waru Sidoarjo. Data were collected through a parental education questionnaire and the PAQ-C instrument, which assesses children’s physical activity over the past seven days. A total of 45 respondents participated, and the data were analyzed using Pearson or Spearman correlation tests, depending on distribution. The findings revealed a positive and statistically significant—though weak—association between parental education and children’s physical activity levels. Parents with higher education tend to promote more active lifestyles by regulating screen time, providing access to sports facilities, and modeling healthy behaviors. These results underscore the essential role of families in developing healthy routines among Generation Alpha and the need for educational initiatives to enhance parental awareness of physical activity in an increasingly digital environment.

The management of Corporate Social Responsibility (CSR) in the banking sector holds strategic importance in strengthening public trust, supporting sustainable development, and ensuring that the distribution of CSR funds aligns with principles of good governance. However, CSR implementation among Indonesian banks continues to face fundamental issues, including limited transparency, inconsistent reporting standards, and weak supervisory mechanisms. This study aims to analyze the synergy between the Financial Services Authority (OJK) and the banking industry in establishing transparent and accountable CSR fund management. Using a normative legal approach combined with institutional analysis, the findings reveal that although OJK has issued sustainable finance regulations such as POJK No. 51/POJK.03/2017, these regulations have not fully ensured the integrity and accountability of CSR distribution. Strengthening reporting standards, ensuring independent audits, and integrating a digital CSR reporting system are essential to enhance oversight. This study proposes a regulatory–institutional synergy model between OJK and the banking sector to build CSR governance that is transparent, participatory, and impact-oriented.  

The rapid advancement of digital technology has significantly influenced students’ learning behavior while gradually reducing their interest in local cultural education, including the study of the Javanese script. This phenomenon is evident at SDIP Haji Muhammad Subandi, where most students still struggle to recognize, read, and understand Javanese characters due to the limited use of engaging and interactive learning media. To address this issue, a 2D educational game was developed as an innovative, contextual, and enjoyable learning medium that integrates cultural elements into an interactive digital learning experience. The design and development process employed the Multimedia Development Life Cycle (MDLC) method, which consists of six stages: concept, design, material collecting, assembly, testing, and distribution. The game was built using Unity software to produce dynamic visuals, responsive controls, and supporting audio elements that enhance the immersive quality of gameplay. The educational game enables students to learn Javanese script through interactive play activities, including letter recognition, pronunciation practice, and quiz-based challenges. Each component was designed to strengthen cognitive understanding while increasing students’ intrinsic motivation to learn. Expert validation results indicated that the game met the “highly feasible” criteria as a learning medium, while user testing showed notable improvements in motivation, engagement, and learning enjoyment. Overall, this educational game not only enhances learning effectiveness but also contributes to the preservation and revitalization of the Javanese script as part of Indonesia’s cultural heritage in the digital era. Therefore, this game-based learning approach serves as an adaptive and culturally grounded educational innovation for primary-level students

This study aims to analyze the effectiveness of natural resource management, particularly water and soil, in increasing agricultural production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. The research approach used was descriptive qualitative through field observations, in-depth interviews with farmers and village officials, and documentation studies from relevant agencies. The results indicate that the irrigation system in Sampali Village is not operating effectively, characterized by shallowing of canals, damaged irrigation walls, and blockages that cause uneven water distribution. This condition has a significant impact on crop yields, with a difference in production between upstream and downstream areas reaching 1.9 tons/ha. Furthermore, soil quality has also declined due to the excessive use of chemical fertilizers, as indicated by a soil pH that tends to be acidic (5.4–6.0), low organic matter content (1.2–1.8%), and decreased soil biological activity. Factors influencing the effectiveness of water and soil management include technical, environmental, socio-economic, and institutional aspects. This study concludes that natural resource management in Sampali Village is still suboptimal, necessitating improvements to irrigation infrastructure, increased use of organic fertilizers, and institutional strengthening and farmer mentoring. These efforts are expected to support sustainable agricultural productivity gains.  

The emergence of a single candidate in the 2024 Batang hari Regional Election represents an interesting illustration of political party strategies in responding to local democratic dynamics. This study aims to analyze the formation of a grand political coalition through the seek efficiency perspective, referring to the concept of political efficiency proposed by(Pamungkas & Parlindungan, 2011). This research employs a qualitative descriptive approach, with data collected through interviews, documentation, and online media analysis. The findings reveal that the establishment of a grand coalition supporting the incumbent pair, Fadhil Arief and Bakhtiar, was primarily motivated by political efficiency considerations in utilizing resources such as time, energy, and cost. Cross-party cooperation was viewed as a strategic measure to enhance campaign effectiveness and strengthen electoral support. For core parties such as PPP and NasDem, this efficiency became more evident once the coalition operated with proper coordination and proportional role distribution. Overall, the study illustrates that coalition formation in Batang Hari reflects a form of rational political behavior oriented toward effectiveness and efficiency, as well as an effort to strengthen local democratic stability through productive political collaboration

This study evaluates the retrofit design of the Semat weir on the Kali Gawe in Jepara Regency. The retrofit aims to adjust the weir’s hydraulic capacity to accommodate estimated flood discharges while ensuring the structure’s stability under applied loads. In the agricultural context, adequate water availability for irrigation directly affects crop yields; conversely, the rainy season often increases river flow and flood risk. Irrigation structures such as weirs are therefore required to raise river water levels to divert flow into irrigation channels and to regulate water distribution. Flood discharge estimates were derived from precipitation data and watershed (drainage basin) characteristics. Flood hydrograph planning is a critical design step for the weir. Log-Pearson Type III analysis was used to determine probable precipitation values for several recurrence intervals. Those design precipitation values were then converted into design flood discharges using synthetic unit hydrograph methods, specifically the Snyder, Nakayasu, and Gamma HSS approaches. Employing the Gamma synthetic unit hydrograph for the 50-year return period (Q50) produced a design flood discharge of 2,536.52 m³/s for that recurrence interval. Structural stability analyses of the redesigned weir indicate safety factors well above customary thresholds: overturning resistance factor = 11.6 (required ≥ 1.5), sliding resistance factor = 4.80 (required ≥ 2.0), and piping (internal erosion) factor = infinite (required ≥ 4). All evaluated stability parameters therefore satisfy standard safety criteria.

Sexually transmitted infections (STIs) are infections that are transmitted mainly through sexual intercourse. Indonesia's 2020 health profile reported that STIs such as HIV are increasing every year. The prevalence of STIs in Indonesia in indonesia was 11,133 cases. The prevalence of syphilis was 3,868 cases, gonorrhea 2,486 cases, and HIV/AIDS 9,327 cases.

The research was conducted at Senior High School 1 Mandiracan in April-June 2024. By using research instruments in the form of questionnaires, this study used primary and secondary data, the analysis in this study used univariate analysis with frequency distribution. The results of this study obtained the results of adolescent knowledge about STIs as many as 50 students (73.5%) were well informed and 28 students (26.5%) were moderately knowledgeable. Adolescents knowledge about sexually transmitted infections at Senior High School 1 Mandirancan Class XI MIPA has good knowledge category. It is expected that the school will collaborate with health workers to conduct socialization about STIs and conduct counseling to students about STIs.

This study evaluated the population status of the conch Strombus luhuanus at Asol Beach, , Haruku Island, Maluku, through an analysis of density, size structure, length–weight relationship, and spatial distribution. Data were collected using transect–quadrat methods in the intertidal zone during low tide, complemented by measurements of environmental parameters (temperature, salinity, pH, and dissolved oxygen). The results revealed a population density of 2.76 ind/m², classified as moderate compared to other sites in Maluku. Shell length distribution encompassed nine size classes, with dominance in the mid-size class (3.93–4.38 cm), indicating successful recruitment of juveniles to early adults. The length–weight relationship followed the equation W = 1.871L0.0521 (R² = 0.857) with a negative allometric growth pattern, suggesting that individuals allocate more energy to shell elongation than body mass increase. The Morisita index (Id = 211.07) indicated an aggregated distribution pattern, consistent with reproductive strategies of broadcast-spawning gastropods. Environmental conditions (temperature 28.7 °C; salinity 32.66‰; pH 6.44; DO 6 mg/L) were within the tolerance range of tropical intertidal mollusks. These findings highlight the critical role of sandy seagrass habitats in supporting S. luhuanus populations and emphasize the need for management strategies based on minimum catch size, harvest regulation, and coastal habitat protection.

This study examines the concept of ukhuwah (brotherhood) from the perspective of the Qur’an as the foundation of social capital in Islam. Social capital in modern social theory is understood as networks, norms, and trust that strengthen collaboration between individuals and groups. In Islam, the spiritual foundation has been embedded through the value of ukhuwah. This research uses the library method with a thematic exegesis (mawdhu’i) approach to analyze the Qur’anic verses related to ukhuwah and link them to modern social capital theory. The findings show that ukhuwah plays an important role in cultivating trust (trust capital), strengthening socio-economic networks (network capital), and promoting fair economic distribution. Therefore, ukhuwah serves as a conceptual foundation for Islamic social capital, which is not only relevant in facing contemporary economic challenges but also supports equitable and sustainable economic development for the community. This study provides an understanding that Islamic social capital, built through ukhuwah, can be a solution for creating social justice and sustainable prosperity in society.

The findings provide guidance for other media in effectively managing content distribution to reach a wider audience.

Oil palm is a leading commodity that makes a major contribution to Indonesia’s economy, yet a significant productivity gap remains between actual and potential yields. A principal cause is suboptimal water management, which leads to flooding during the rainy season and drought in the dry season. This study develops a Conceptual Design (CD) for water management to map existing problems, analyse root causes, formulate improvement measures, and present a macro-level cost estimate for the study site. The research was conducted at an oil palm plantation in East Kalimantan anonymized as “PT XYZ.” The site was selected due to recurrent flooding and a recent change in ownership that limited data availability, making it well-suited for a CD-stage assessment. The objective is to identify water management issues and propose effective recommendations. A quantitative approach integrates primary data from field observations and measurements with secondary data. The analyses cover flood problem assessment, Water Management Zoning (WMZ/ZPA), rainfall analysis, hydrology, hydraulics, improvement proposals, and macro cost estimation. Results indicate that challenges are driven by swampy land conditions and inadequate channel and hydraulic structure capacity. Micro-watershed delineation using DEMNAS identified four ZPAs totalling 479–4,061 ha. Design rainfall was derived from CHIRPS satellite data using a log-normal distribution. Hydrologically, peak discharges range from 3.87–22.58 m³/s for the 2-year return period and 4.46–26.31 m³/s for the 5-year return period. Hydraulically, the proposed dimensions for rivers, outlet drains, carrier drains, and field-edge drains are 4×3×2 m to 9×7×3 m (T=2 years) and 4×3×2 m to 10×8×3 m (T=5 years), while collection and main drains are proposed at 3×2×2 m for both return periods. The total estimated investment for the 5-year design scenario is IDR 27,999,263,000.
