Bullying in the school environment is a social health problem that has a massive impact on children’s physical, mental, and social well-being. As the primary educational environment, schools need to implement a structured, safe, and child-friendly bullying reporting system. Objective: This conceptual study aims to design the implementation of a bullying reporting system based on school health administration using the functional management approach: planning, organizing, actuating, and controlling (POAC). The methods and components of the reporting system are designed through the four POAC pillars, namely the establishment of an Anti-Bullying Team, the preparation of Standard Operating Procedures (SOPs), the provision of child-friendly reporting media both physical and digital through the School Health Unit (UKS), and the development of monitoring and evaluation mechanisms (controlling). School health administration is used as an initial screening tool to identify indications of victim trauma discreetly and safely. The implementation of this POAC-based system is expected to improve the early detection of bullying cases, accelerate case handling responses, and eliminate stigma and fear of reporting among children. Conclusion: The integration of health administration and POAC management has proven to be a strong framework for creating a safe, inclusive school environment that strongly supports students’ mental health recovery.

Culinary MSMEs play a crucial role in supporting the regional economy, including in Kolaka Regency, Southeast Sulawesi. However, sole proprietorships in this sector still face significant challenges, particularly related to limited access to capital. This study aims to explore the relationship between limited capital and the sustainability of sole proprietorships in the culinary sector in Kolaka Regency, considering influencing factors such as family support, local government policies, and local market dynamics. This study employed a qualitative approach with a case study method. Data were obtained through in-depth interviews, field observations, and documentation. Informants were purposively selected from sole proprietorships in the culinary sector who had been operating their businesses for at least two years. The results show that limited capital is not only a simple financial barrier but also directly impacts the business's ability to innovate, maintain product quality, expand market reach, and survive competition. Most entrepreneurs rely on personal capital and informal loans from family, while access to formal financial institutions remains very limited due to complicated administrative procedures and low financial literacy. Business sustainability is heavily influenced by personal adaptation strategies, community support, and the gradual building of customer trust. This study recommends strengthening financial literacy, simplifying credit access procedures, and enhancing local government involvement in building a more environmentally friendly business ecosystem for local culinary MSMEs.

Long fishing is an environmentally friendly traditional fishing tool that is commonly used by fishermen to catch fish passively using bait, both in sandy waters and in coral reef areas. Grouper fish (Epinephelus sp.) tend to inhabit waters of a certain depth, especially in areas of coral fractures and dead corals that serve as shelter and foraging. Determining the right depth setting in the operation of a fishing rod is essential to optimize the catch. This study aims to determine the effect of the difference in setting depth on grouper fish catch in the waters of Pengambengan Beach and determine the most effective depth. The study used an experimental method with three depth treatments, namely 10 m, 15 m, and 20 m, each repeated nine times. Data analysis was carried out by Group Random Design (RAK) and ANOVA test. The results showed that a depth of 10 m produced the highest catch with a total of 35 fish (average 3.89 fish/trip), followed by a depth of 15 m with 10 fish (average 1.11 fish/trip), and a depth of 20 m with 7 fish (average 0.78 fish/trip). Statistically, the difference in depth has a real influence on the number of grouper catches. A depth of 10 m is recommended as the optimal setting for the operation of long fishing rods in the waters of Pengambengan Beach.

Abstract: Padukuhan Karangrejek, Karangtengah, Imogiri, Bantul, is a sloping area prone to landslides due to high rainfall, soil erosion, and vegetation degradation.
