Anemia is a common health problem among adolescent girls, especially in developing countries like Indonesia. This condition is generally caused by insufficient iron intake, an unbalanced diet, and increased iron requirements during growth. Anemia not only impacts physical health but also affects concentration, productivity, and quality of life. Therefore, interventions based on nutrition education and the utilization of local food sources are crucial in sustainable anemia prevention efforts. One potential complementary therapy alternative is the consumption of herbal drinks based on moringa leaves (Moringa oleifera). Moringa leaves are known to be rich in iron, vitamin A, and antioxidants that play a role in red blood cell formation. This community service activity aims to increase the knowledge and skills of adolescent girls in utilizing moringa leaves as a natural source of iron. The target group is grade 10 and 11 female students at SMA Sejahtera Palembang, which was held in June 2025. The activity methods included a nutrition lecture on anemia and the importance of iron, an interactive discussion on the benefits of moringa leaves, and hands-on practice in making herbal moringa drinks (such as moringa leaf tea and moringa juice). The material was delivered using a communicative and participatory approach to actively engage participants. The results of the activity showed an increase in participants' understanding of the causes of anemia, the benefits of moringa leaves, and their willingness to consume herbal drinks as a preventative measure. Most participants also expressed interest in trying to make their own moringa herbal drink at home. This activity is expected to become part of school-based promotional and preventive efforts to address anemia in adolescent girls.

Pembangunan berkelanjutan menuntut pengelolaan sumber daya yang efisien dan ramah lingkungan. Penelitian ini mengkaji integrasi tiga sistem utama: pembangkit listrik tenaga mikro hidro (PLTMH), sistem plumbing hemat air, dan alat pirolisis sampah rumah tangga. Ketiganya dianalisis melalui studi literatur dan perbandingan data dari tiga studi kasus di Indonesia. Hasil menunjukkan bahwa PLTMH di Dusun Batu Rangin mampu menghasilkan daya 48,56 kW dan mengurangi emisi CO? sebesar 156 ton/tahun. Sistem plumbing hemat air di Rusun Brimob Sampali menurunkan konsumsi air hingga 33,52% dan meningkatkan efisiensi daur ulang air hingga 87%. Sementara itu, pirolisis sampah rumah tangga menghasilkan bio-oil dengan nilai kalor tinggi dan menunjukkan potensi ekonomi dengan ROI 1,58. Integrasi ketiga sistem ini membentuk model pengelolaan sumber daya yang saling mendukung, dengan indeks keberlanjutan 3,7 dari 5. Pendekatan ini sejalan dengan konsep circular economy dan berpotensi diterapkan secara luas di wilayah pedesaan Indonesia.

The assignment problem discusses the problem of creating maximum sales, CV Surya Pelangi assigns its selected employees to enter the target market. CV Surya Pelangi has problems allocating its employees to the target market that has been determined. Before allocating its employees, CV Surya Pelangi has conducted training first. The income data of each employee in these markets is in (thousands) during training, therefore it is necessary to solve the employee allocation problem. The method used in this study is the Hungarian Method, with a focus on the maximization approach. The Hungarian method is known to be effective in solving assignment problems where there are similarities in the number of employees and allocations, and the goal is to optimize the allocation. In this case, maximization means finding a combination of assignments that produce the highest total profit value.

Work in the informal sector, such as weaving, has high health risks due to the repetitive nature and static positions required. Weavers often experience Musculoskeletal Disorders (MSDs) due to sitting too long in front of the loom for about 8 hours. This condition causes muscle contractions in the shoulders and neck, reduces blood flow, and causes pain and fatigue. A study of two sarong weaving industries in Dalangan Village found that 70% of 10 workers complained of low back pain. Many workers work with non-ergonomic positions and inappropriate equipment. Improvements in work attitudes are needed so that workers' health and productivity are maintained. This study aims to determine the relationship between work attitudes and MSDs disorders in the central craftsmen of the weaving industry. This research is a quantitative study using observational analysis method with cross sectional approach. The population was 35 from 4 locations with a sample of 35 respondents taken using total sampling technique. Assessment for work attitudes using the Rapid Entire Body Assessment (REBA) and for Musculoskeletal Disorders (MSDs) experienced using the Nordic Body Map (NBM). The results of the Spearman correlation test showed no significant relationship between work attitudes and musculoskeletal complaints with a p-value = 0.261 (p < 0.05) and a correlation coefficient value of r = 0.195 which is included in a weak correlation with a positive direction. The study shows there is no significant relationship between work attitude and musculoskeletal disorders in weaving industry workers. Routine ergonomics education is recommended to prevent complaints and maintain sustainable occupational health.

This research aims to explore the ways in which teachers address the challenges of learning mathematics for children in primary schools by referring to behavioristic theory. This theory emphasizes the central role of stimuli and reactions in influencing learning behavior, and the application of both positive and negative reinforcement to improve students' motivation and understanding. The approach adopted was a descriptive qualitative method using case studies in various primary schools. The results indicated that behavior-focused methods, such as providing repeated practice of problems, immediate feedback, use of concrete tools, and regular application of rewards and punishments, can improve students' enthusiasm and mathematics learning outcomes. However, teacher-driven learning and lack of innovation are barriers to implementation. Therefore, a combination with other methods is needed to make the learning process more thorough.

This study aims to describe the application of the inquiry approach in science learning for early childhood. The inquiry approach is believed to be able to foster curiosity, critical thinking skills, and exploration skills in children from an early age. The research method used is descriptive qualitative with observation and documentation techniques. The subjects of the study were children in the Playgroup at Kiddie Care. The results of the study indicate that the inquiry approach can increase children's active involvement in the science learning process, such as when observing objects, asking questions, and trying to find answers through simple experiments. The application of inquiry also encourages children's communication and cooperation skills in groups. Thus, the inquiry approach is effectively applied in science learning in PAUD.

This study examines the effect of halal supply chain management and product innovation on micro business performance with halal certification as a mediating variable. The background of this study is based on the low performance of micro businesses, lack of product innovation, and minimal halal certification in Bandung City, although Bandung City has great potential in developing the halal industry. This study uses a descriptive quantitative approach with data collection through questionnaires on 260 micro business actors in the halal food and beverage sector in Bandung City, which were analyzed using PLS-SEM with path analysis methods to test direct and indirect relationships between variables. The results of the study indicate that halal supply chain management has a significant effect on halal certification, but Halal Supply Chain Management does not have a significant direct effect on Micro Business Performance. Meanwhile, product innovation does not have a significant effect on business performance and halal certification. Halal Certification is proven to have a significant effect on Micro Business Performance. Halal certification is proven to mediate the relationship between halal supply chain management and business performance, but does not mediate the effect of product innovation on business performance. These findings provide implications for business actors and the government in formulating strategies to increase the competitiveness of halal micro businesses by strengthening supply chain management and facilitating halal certification.
