Abstract

Low mathematics learning outcomes among elementary school students remain a persistent challenge in Indonesia, particularly in regions characterized by diverse socio-cultural backgrounds and limited instructional resources. This study investigated the comparative effectiveness of the compassion-integrated GASING method and the Concrete Pictorial Abstract (CPA) approach in enhancing mathematics achievement among fourth-grade elementary students in Nabire Regency, Papua. A quasi-experimental nonequivalent control group design was employed, with 125 students from six elementary schools comprising the analyzed sample, of whom 59 were assigned to the experimental group receiving the compassion-integrated GASING method and 66 to the control group receiving the CPA approach. Data were collected through a 20-item multiple-choice mathematics achievement test covering addition operations, validated through Pearson correlation analysis and demonstrating high reliability (Cronbach's Alpha = 0.871). The enactment of the compassion-integrated GASING method was assessed through structured observation checklists completed by classroom teachers at each session, yielding a mean implementation fidelity of 99.19%, compared to 97.22% for the CPA approach, with both classified as Very Good. Inferential analysis proceeded in two stages. The Wilcoxon Signed-Rank test revealed statistically significant within-group gains in both the experimental group (Z = -6.689, p < .001, r = 0.871) and the control group (Z = -7.017, p < .001, r = 0.864), with both effect sizes classified as large. The Mann-Whitney U test subsequently indicated no statistically significant between-group difference in posttest outcomes (U = 1826.000, Z = -0.601, p = .548, r = 0.054). These findings confirm that both approaches produced comparably equivalent and practically significant gains in mathematics learning outcomes. The high fidelity of compassion-based instruction observed across all sessions provides empirical support for the consistent enactment of the affective dimension of the intervention, though its direct impact on students' emotional outcomes warrants further investigation using validated affective instruments. These findings suggest that teachers in diverse and underserved elementary settings may confidently adopt either approach, with the compassion-integrated GASING method offering additional promise as a contextually responsive instructional model.

Abstract

Nutritional challenges among Indonesian school-aged children persist due to limited nutrition literacy and the absence of structured, curriculum-integrated instruction. While food provision remains important, meaningful progress requires effective pedagogical strategies within primary education. However, teachers often lack access to government-endorsed, culturally relevant resources and targeted professional development. This qualitative study investigates the perceptions of six purposively selected primary teachers (three males, three females), trained in STEM and gamification, regarding the use of traditional Indonesian foods and Augmented Reality (AR) to support nutrition education. A descriptive research design was employed, with data collected through semi-structured interviews and non-participant classroom observations of science lessons incorporating game-based learning. Thematic coding and triangulation techniques enhanced analytical rigour and credibility. Findings suggest that teachers demonstrated a sound grasp of nutrient content in traditional foods—such as cassava and fish—and integrated these examples into science topics like digestion and body systems. While realia proved more effective with younger pupils, AR enabled older learners to visualise microscopic processes, including nutrient breakdown during cooking. Teachers perceived AR as fostering inquiry-based learning, promoting cultural authenticity, and aligning with Green-STEM values. They also acknowledged the influence of Generation Alpha’s digital habits and stressed the importance of age-appropriate, visually engaging approaches. This study concludes that culturally grounded AR resources, when combined with sustained teacher training, offer significant potential to enhance nutrition education in primary schools. Practical implications include the phased integration of AR-based ethnoscientific content into curricula, the use of gamified strategies to promote sustainable dietary behaviours, and further longitudinal research into the pedagogical impact of educational technology in nutrition learning.

Abstract

This study examines the effectiveness of a workshop in improving school principals' perceptions regarding deep learning implementation using the RADEC model (Read, Answer, Discuss, Explain, Create) in Bandung City, Indonesia. Using a weak experiment design with one group pretest-posttest non-control method and 14 perception indicators, Mann–Whitney U analysis revealed that the workshop significantly improved principals' understanding in 10 of 14 indicators (p < 0.05), particularly on RADEC syntax stages and their contribution to 21st-century skills. However, three foundational deep learning principles (joyful, meaningful, mindful learning) and the Answer stage showed strong understanding prior to the workshop (p > 0.05), indicating the workshop successfully closed knowledge gaps in technical RADEC aspects. Although effectiveness is limited to the perception dimension rather than direct implementation impact, these findings confirm the workshop was effective as a cognitive foundation for adopting innovative pedagogy. The study recommends: (1) continuous mentoring to transform perception into practice; (2) intensive coaching program by the Education Office through lesson study and community of practice; (3) integration of technical and philosophical dimensions in professional development initiatives. The research implies that while workshops are crucial, they are insufficient educational transformation requires a systemic support ecosystem connecting knowledge with implementation at the school level.

Abstract

Purpose of the study: This study aimed to develop and optimise a technologically relevant non-thermal acid-induced maturation process for giant gourami by identifying effective citrus acid formulations and immersion durations that enable controlled myofibrillar protein denaturation for scientifically standardised and traditional Dekke Naniura processing. Methodology: A laboratory-based semi-controlled experimental design was applied using fresh gourami fillets immersed in organic acids derived from lime (Citrus aurantiifolia) and lemon (Citrus limon) juices at different ratios and immersion times. Maturation progression was evaluated using a semi-quantitative visual index (0–100%) supported by triplicate mean ± SD measurements. Observations included colour transformation, flesh firmness, and macroscopic protein denaturation, while microscopic assessment and mechanical texture analysis validated structural myofibrillar changes. Statistical analysis using one-way ANOVA and Tukey’s HSD determined significant treatment differences. Main Findings: The optimal condition was a formulation containing 75% lime juice and 25% lemon juice with an immersion duration of 1,140 minutes, achieving 96% maturation. This treatment produced homogeneous myofibrillar protein denaturation, uniform colour transformation, and increased flesh firmness under non-thermal conditions. Single-acid treatments showed slower and less uniform maturation, indicating a synergistic effect of mixed citrus acids. The dense muscle fibre structure and high myofibrillar protein content of gourami contributed to enhanced structural stability during maturation. Statistical analyses confirmed significant differences among treatments at most immersion times. Novelty/Originality of this study: This study proposes a reproducible and chemically optimised non-thermal maturation model integrating semi-quantitative, microscopic, and mechanical analyses, providing a scientifically validated framework for modern adaptation of traditional Batak naniura processing.

Abstract

Awareness among Indonesian society regarding plastic use and its management remains alarmingly low. This highlights an urgent need to strengthen sustainability education and responsible environmental practices. The implementation of the Plastic Pollution Management Worksheet uses a practicum-based method to foster greater sustainability awareness by integrating critical reflection and problem-solving strategies in addressing plastic pollution. This hands-on approach also encourages pro-environmental behavioural changes among learners. This study seeks to evaluate the impact of the Plastic Pollution Management Worksheet in practicum on students' sustainability awareness before and after its use. A one-group pre-test and post-test design was adopted, involving 40 university students, with a self-efficacy questionnaire used to assess five key indicators of sustainability awareness. The findings indicate that the implementation of practicum with the Plastic Pollution Management Worksheet had a moderate impact on enhancing students' sustainability awareness, with the most notable improvements observed in cognitive awareness (understanding sustainability concepts) and social engagement. Although improvements were noted across all dimensions, the development of sustainable behavioural changes requires further time and reinforcement. In conclusion, the practicum with Plastic Pollution Management Worksheet demonstrates potential as an innovative pedagogical strategy in sustainability education, though its effectiveness could be maximised by integrating it with other complementary educational approaches.

Abstract

This study examines the effectiveness of project-based edu-tourism (PBET) in mangrove ecosystems for enhancing environmental literacy among university students, with particular attention to the role of initial academic ability. A 2×2 factorial design was employed with 75 students from the PGMI Department at UIN Mataram, divided into an experimental group (38 students) participating in a two-week PBET program and a control group (37 students) receiving conventional classroom instruction. Environmental literacy was assessed through pre- and post-test measures, with learning improvement calculated using N-gain scores. The results from factorial ANCOVA revealed that the PBET group achieved significantly higher post-test scores compared to the control group (F(1,70) = 167.344, p < .001), demonstrating the effectiveness of PBET in enhancing environmental literacy. However, initial academic ability was not a significant predictor of environmental literacy outcomes (F(1,70) = 0.098, p = .755), nor was the interaction between class type and initial academic ability significant (F(1,70) = 0.002, p = .961). These findings suggest that PBET is an effective pedagogical approach for improving environmental literacy across diverse academic levels, underscoring its potential for inclusive, experiential learning.
