Anemia remains a significant nutritional problem among adolescent girls due to increased iron requirements during growth and menstruation. Iron (Fe) tablet supplementation is commonly used for prevention, but low compliance often limits its effectiveness. Moringa oleifera leaf tea offers a potential local food–based alternative intervention. This study aimed to compare the effectiveness of Moringa oleifera leaf tea and iron tablets in increasing hemoglobin levels among anemic adolescent girls. A quasi-experimental two-group pretest–posttest design was employed in December 2025 at two junior high schools in Gorontalo City. The sample consisted of 18 adolescent girls with mild to moderate anemia, divided equally into a Moringa leaf tea group and an iron tablet group. The tea group consumed Moringa leaf tea twice daily for 14 days, while the tablet group consumed one iron tablet per week for two weeks. Hemoglobin levels were measured before and after the intervention using a digital hemoglobin analyzer. Data analysis using the Wilcoxon signed-rank test and Mann–Whitney test showed that both interventions significantly increased hemoglobin levels. However, the increase was greater in the Moringa group (ΔHb 1.4–3.2 g/dL; p = 0.008) compared to the iron tablet group (ΔHb 0.5–0.8 g/dL; p = 0.007). A significant difference between groups (p < 0.001) indicates that Moringa oleifera leaf tea is more effective as an alternative intervention.

This study uses a quantitative method with an explanatory approach to explore factors contributing to low pension literacy among workers. The sample consisted of 66 workers from both the formal and informal sectors in Jakarta in December 2025. The findings reveal that low pension literacy is not solely due to a lack of knowledge but results from various factors, including low awareness, short-term financial behavior, product complexity, inadequate education, and underutilization of digital tools. There is a mismatch between workers' perceptions and the reality of pension fund behavior. The majority of workers (86%) are unprepared for retirement, and 89% do not have a voluntary pension fund. Despite this, 80% do not rely on workplace pension funds, and 45.5% feel confident they can meet their living expenses in old age, indicating pseudo-awareness they understand the importance of pension funds but have not established one. This reveals a gap between awareness and action regarding pension funds. Improving pension literacy requires an integrated approach that combines transformative education with digitalization to facilitate access and participation. Education must drive behavioral change, while digitalization simplifies processes, enhances accessibility, and broadens financial literacy. The synergy of education, digital technology, and policy support is essential for improving workers' financial readiness for a secure retirement.

This literature study examines the process of self-regulation in transforming compliance with school rules originating from external pressure into behavioral regularity emerging from personal awareness, and its impact on the effectiveness of student learning outcomes. Using a qualitative approach with content analysis method, this study synthesizes relevant literature to build a theoretical framework on how self-regulation facilitates the internalization of disciplinary values. The findings reveal that self-regulation occurs through a series of interconnected stages including goal setting, strategy planning, self-monitoring, evaluation, and adjustment. The success of this process is determined by internal motivation, appropriate environmental support, positive direct experiences, and healthy emotional management. Strong self-regulation directly impacts learning outcome effectiveness through improved cognitive strategies, strengthened intrinsic motivation, enhanced time and environment management, and developed capacity to constructively cope with failure. Learning outcomes achieved through self-regulation processes are characterized by lasting understanding, knowledge transfer ability, and the formation of lifelong learning dispositions. Schools and teachers play strategic roles in strengthening self-regulation through curriculum design that supports autonomy, formative feedback, role modeling, and collaboration with parents. This study contributes theoretically by positioning self-regulation as the central mechanism bridging external influences and internal disposition formation.
