Abstract

Mild to moderate anemia impairs cognitive performance and academic engagement among adolescent girls, yet school-based nutrition programs in Indonesia focus largely on iron and vitamin A. This study evaluated whether a focused 30-day regimen of 20 mg/day zinc could improve both hemoglobin concentration and attention, as measured by the Stroop Color–Word Test, in 30 junior high school girls with baseline hemoglobin < 12 g/dL. Following daily supplementation, mean hemoglobin rose from 10.6 ± 0.5 g/dL to 12.4 ± 0.4 g/dL (Δ = 1.8 g/dL, p < 0.001, Cohen’s d = 3.86), fully eliminating moderate anemia in this cohort. Stroop scores increased from 61.2 ± 5.3 to 75.8 ± 4.6 points (Δ = 14.6, p < 0.001, Cohen’s d = 2.88), with no students remaining in the lowest concentration category post-intervention. These parallel gains reflect zinc’s dual role in enhancing erythropoiesis improving cerebral oxygen delivery and modulating neurotransmission via NMDA/GABA balance and BDNF upregulation. Effect sizes exceed those typically reported for iron-only or broader micronutrient interventions. Findings support integrating a one-month zinc supplement into Indonesian school-health protocols to rapidly correct anemia and bolster cognitive readiness for learning.

Abstract

This article is about developing mathematics learning materials related to the Indonesian Realistic Mathematics Education (PMRI) approach for teaching the circle topic, with a focus on enhancing sixth-grade students’ conceptual understanding of π (Pi) at MI Ma’arif Pagerwojo. The development followed the ADDIE instructional design model. The research instruments included expert validation sheets, lesson implementation observation sheets, response questionnaires, and achievement tests. Based on expert validation, two validators rated the teaching module at 95.5% and 92.6%, the student worksheet (LKPD) at 91.6% and 94%, and the learning outcome test at 85% and 90% all falling within the "highly valid" category. Observation results of lesson implementation by both teacher and students yielded scores of 90% and 87.5%, respectively, while teacher and student response questionnaires reached 93.7% and 87%. It shows that the developed learning materials are highly practical. The effectiveness also has been proved, as 80% of students met the minimum mastery criterion (KKM), satisfying the criterion for classical completeness. These findings demonstrate that PMRI-based materials effectively facilitate students’ meaningful understanding of π through contextual learning activities. Moreover, the context of this study focused on developing instructional materials at the primary school level remains underexplored in educational development research. Thus, this study may serve as a reference for broader international mathematics education, particularly since PMRI aligns closely with the principles of Realistic Mathematics Education (RME).

Abstract

This study investigates the impact of the Problem-Based Learning (PBL) model on elementary students' mathematical critical thinking skills and resilience. Employing a quasi-experimental design with a pretest-posttest control group, the research involved 45 fifth-grade students divided into experimental and control groups. Validated instruments, aligned with higher-order thinking and affective constructs, were used to assess critical thinking and mathematical resilience. Quantitative findings demonstrated that the PBL model led to statistically significant improvements in both constructs. Students in the experimental group outperformed their peers, with large effect sizes (Cohen’s d = 2.51 for critical thinking, 2.35 for resilience), and the Mann-Whitney U test confirmed significant intergroup differences. Furthermore, Spearman correlation analysis (r = 0.460, p < 0.05) revealed a moderate positive relationship between resilience and critical thinking. Qualitative analysis showed that students with higher resilience provided more reflective and elaborate responses. The study emphasizes the educational potential of integrating affective-cognitive instructional models. PBL not only enhances academic performance but also supports students’ emotional persistence and adaptability in learning mathematics. However, limitations such as small sample size and sampling method should be considered in interpreting the results. The study concludes that fostering mathematical resilience is essential to optimizing the cognitive benefits of PBL and recommends teacher training and curriculum strategies to implement this dual-focused approach effectively.

Abstract

The rapid expansion of urban populations and changing consumption behaviors have intensified solid waste challenges, particularly in developing countries like Indonesia. Used beverage cartons (UBCs), composed of layered paper, plastic, and aluminum, are among the most difficult packaging materials to recycle. Extended Producer Responsibility (EPR) is increasingly promoted as a policy mechanism to shift waste management responsibilities from local governments to producers. However, the implementation of EPR in Indonesia remains limited due to weak infrastructure, low market incentives, and fragmented stakeholder coordination. This study aims to identify strategic priorities for EPR implementation in managing UBC waste by applying the Analytical Hierarchy Process (AHP), integrated with a penta-helix stakeholder framework. Conducted in East Jakarta between March and November 2023, the research engaged five expert informants representing government, academia, industry, civil society, and waste management sectors. Through structured pairwise comparisons, the study evaluated five sub-criteria: stakeholder participation, regulatory framework, financial incentives, market access for recycled UBCs, and recycling technology. The AHP analysis revealed that stakeholder participation holds the highest priority weight (48.31%), followed by the regulatory framework (34.57%) and financial incentives (9.64%). Market and off-taker availability (5.63%) and recycling technology advancement (1.85%) were identified as lower-priority but still necessary components. These results indicate that socio-economic considerations dominate strategic decision-making in UBC waste management. The study offers a data-driven and context-sensitive framework for EPR implementation that can inform policymakers and industry actors. Furthermore, the AHP model demonstrates potential for replicability in other complex waste streams requiring coordinated multi-stakeholder engagement.

Abstract

This study investigates the implementation of a contextual Project-Based Learning model (Ethnomed-PjBL) that connects pharmacy students with traditional healers (Belian) in Lombok, Indonesia, to explore and scientifically validate ethnomedicinal formulations. Conducted in three phases field immersion, in-situ qualitative testing, and laboratory-based phytochemical analysis the model facilitated reciprocal learning and empirical inquiry grounded in Indigenous healing knowledge. Laboratory screening confirmed the presence of key secondary metabolites across all formulations, including flavonoids, tannins, alkaloids, phenolics, and terpenoids. Among the seven formulations tested, those based on Ziziphus mauritiana (bidara) and Annona muricata (soursop) showed the highest chemical diversity and antioxidant activity, with IC₅₀ values of 61.2 µg/mL and 74.5 µg/mL, respectively. These results support the pharmacological potential of traditional remedies and align with healer-reported uses related to immune function and disease prevention. Students reported significant educational gains, including improved understanding of phytochemistry, enhanced laboratory competence, critical thinking, and greater intercultural and ethical awareness. The Ethnomed-PjBL model demonstrated the capacity to embed scientific inquiry within culturally responsive frameworks, reinforcing the relevance of Indigenous knowledge in contemporary pharmaceutical education. By promoting equitable academic–community partnerships, this model contributes to broader efforts to decolonize health education and advance pharmaceutical sovereignty. It offers a replicable framework for integrating traditional knowledge into vocational health curricula, balancing scientific rigor with cultural respect. The study underscores the importance of ethical collaboration in preserving traditional knowledge systems while cultivating future health professionals who are both scientifically competent and culturally attuned.
