Abstract

Meaningful learning in digital electronics requires hands-on practicum activities to support students’ understanding of abstract logic concepts. However, limited access to appropriate practicum media often hinders effective learning experiences. This study aims to develop and validate a physical Basic Logic Gate practicum module designed to support hands-on learning in digital electronics courses. The study employed a Research and Development approach using the 4D model, completing the Define, Design, and Develop stages up to expert validation and student practicality testing. The developed module consists of a hardware-based logic gate kit that enables students to assemble and test basic logic gate circuits directly during practicum sessions. Content and media validation were conducted by a material expert and a media expert using a Likert-scale instrument, while practicality testing involved 28 undergraduate students. The validation results indicated high validity, with scores of 96.19% from the material expert and 97.14% from the media expert. Practicality testing yielded an average score of 98.57%, indicating that the module is highly practical in terms of usability, functionality, and suitability for practicum implementation. These findings demonstrate that the developed Basic Logic Gate practicum module meets quality standards for instructional media and is feasible for use in digital electronics practicum learning.

Abstract

The objective of this study is to investigate how STEM (Science, Technology, Engineering, and Mathematics) education contributes to enhancing self-efficacy and control-of-variables strategy (CVS) skills among prospective elementary school teachers, using a Systematic Literature Review (SLR) methodology. This research examined 15 well-regarded international articles that were published between 2020 and 2025 and are indexed by Scopus. To guarantee a systematic, transparent, and responsible review process, the identification, selection, and inclusion of literature were carried out in accordance with PRISMA guidelines. The findings concerning STEM learning models, instructional strategies, and their effects on the psychological and cognitive aspects of prospective teachers were synthesized using thematic analysis. Studies show that STEM approaches based on inquiry, project-based learning, and engineering design consistently improve prospective teachers' self-efficacy in science teaching and strengthen their ability to regularly control variables in experiments. Furthermore, the implementation of the Flipped Classroom model and the integration of digital technology contributes to meaningful learning experiences (mastery experiences), enhanced collaboration, and the development of analytical thinking and problem-solving skills. However, several challenges remain, such as the gap between theory and practice, differences in program duration, and limitations in the development of computational literacy. Overall, STEM learning contributes to preparing prospective elementary school teachers who are confident, reflective, and competent in designing inquiry and technology based science lessons to support the creation of quality science education.

Abstract

This study aims to examine how an ethnoscience-based durian acid product-development project functions as a PCK-driven creative learning environment for prospective chemistry teachers and to analyze creativity across elaboration, originality, problem solving, and synthesis. A Classroom Action Research (CAR) design with an embedded mixed-methods approach was employed involving 68 fifth-semester pre-service chemistry teachers at the University of Riau. The intervention integrated Project-Based Learning (PjBL) stages—orientation, planning, implementation, and evaluation—within Plan–Act–Observe–Reflect cycles. Data were collected using creativity questionnaires, classroom observations, and interviews, and triangulated to validate findings. Results showed high agreement (74–93%) across creativity dimensions during orientation–implementation, supported by observed evidence of detailed planning, novel product ideas, and iterative troubleshooting. However, more neutral responses emerged during evaluation, indicating difficulties in evidence-based reflection and conceptual integration. The core chemistry concepts addressed included fermentation chemistry, pH interpretation, solution dilution, and acid strength comparisons. Triangulation was generally convergent, with partial divergence in originality during evaluation due to discrepancies between self-perceived novelty and observed pedagogical innovation. These findings suggest that ethnoscience-enriched PjBL effectively promotes creative PCK development, but requires structured scaffolding to strengthen data-driven justification and synthesis during reflective evaluation.

Abstract

This study aims to evaluate the effectiveness of Duolingo as a reinforcement activity and analyze the relationship between objective and subjective usage intensity, vocabulary mastery, and learning motivation. Utilizing a quantitative approach with a correlational design, data was collected from 21 Junior High School students selected via purposive sampling. The instruments included digital logs from Duolingo for Schools, pretest-posttest vocabulary assessments, and questionnaires, which were analyzed using the Wilcoxon Signed Rank Test and Spearman Rank Correlation. The results demonstrated a significant increase in vocabulary mastery, achieving a medium N-Gain of 0.29, alongside high, predominantly intrinsic learning motivation with a mean score of 3.48. However, the discussion reveals a distinct "intention-behavior gap," showing a discrepancy between students' perceived subjective intensity and their actual objective usage logs. Furthermore, statistical analysis indicated no significant linear correlation between the duration of use and the improvements in vocabulary or motivation. In conclusion, while Duolingo serves as an effective structured reinforcement tool to enhance engagement and foundational vocabulary, the duration of app usage alone does not determine success, thereby highlighting an "illusion of productivity" within self-directed mobile learning.

Abstract

Land use change analysis is widely applied in watershed studies, yet its reliability is often limited when multi-temporal classification accuracy is not systematically evaluated. This study aims to assess long-term land use change while emphasizing the accuracy and reliability of change detection in the Petung Watershed, East Java, Indonesia. Multi-temporal Landsat imagery from Landsat 7, 8, and 9 (2005–2024) was analyzed using a supervised classification approach implemented in ArcGIS. Classification accuracy was evaluated using a confusion matrix and the Kappa coefficient to ensure temporal consistency and methodological reliability. The results indicate a clear shift in land use patterns, characterized by a continuous decline in vegetation cover and a substantial expansion of agricultural and built-up areas. Classification reliability is supported by Kappa coefficient values ranging from 0.701 to 0.829, corresponding to substantial to almost perfect agreement, with the highest accuracy achieved in the later observation years. These findings demonstrate that the proposed supervised, GIS-based framework provides a reliable and replicable approach for accurately measuring long-term land use change at the watershed scale. While the methodology can be applied to other regions, the observed land use dynamics are specific to the Petung Watershed and reflect local environmental and anthropogenic conditions.

Abstract

Coffee plantations support diverse insect communities that play key roles in pest regulation, pollination, and ecosystem stability. This study analyzed insect family composition, abundance, and community structure in the Tim-Tim (Typica) coffee plantation ecosystem in Rusip Antara Subdistrict, Central Aceh Regency, using different trapping methods. Sampling was conducted from May to September 2025 in one representative plantation block with three observation plots, each containing 25 coffee plants. Three types of traps were employed: light traps, yellow plate traps, and malaise traps. Insect community structure was analyzed using the Shannon–Wiener diversity index (H’), evenness index (E), and similarity index. A total of 2,659 individuals from 65 families were recorded, dominated by Hymenoptera, Diptera, Coleoptera, and Hemiptera. Light traps captured the highest number of individuals and exhibited the highest diversity (H’ = 2.34), reflecting the activity of nocturnal insects attracted to light. Yellow plate traps showed moderate diversity (H’ = 1.77) but the highest evenness (E = 0.80), indicating balanced diurnal insect communities. Malaise traps recorded lower diversity (H’ = 1.33) and evenness (E = 0.57), primarily capturing high-flying insects such as Diptera and Hymenoptera. Similarity analysis revealed moderate to low overlap among trap types, demonstrating that different traps capture complementary components of the community. These findings highlight the high insect diversity and ecological stability of the Tim-Tim coffee plantation and emphasize the importance of multiple trapping methods for understanding community structure and supporting natural biological control in sustainable coffee agroecosystems.

Abstract

Pineapple is a key agricultural commodity in Subang Regency. One method of food diversification is transforming pineapple into pineapple jam. Mochi, a food product, can be filled with this pineapple jam. The chemical characteristics and consumer acceptance of pineapple mochi are influenced by the proper ingridients formulation. This study aims to determine the chemical and organoleptic characteristics of pineapple jam as mochi filling. The research design used in this study was a two-factorial Completely Randomized Design (CRD), with the factors being sugar concentration (30%, 40%, and 50%) and pectin concentration (without pectin, 0.015%, and 0.03%). The parameters tested included chemical analysis (water content, total acidity, total soluble solids, and Vitamin C content) and organoleptic evaluation (hedonic test for color, taste, texture, and aroma). The results showed that sugar and pectin treatment had a significant effect on water content G3 21.16b%, total acidity G1 1.90b%, and total soluble solids G3 77.26b%, but did not significantly affect Vitamin C content in the jam 2.20-7.33 m/100 g. Pectin treatment had a significant effect on water content P2 23,27a%, Vitamin C P3 7.09b%, total acidity P3 2.17c%, and total soluble solids P2 76.44b%. There was no interaction between the sugar and pectin treatments on the pineapple mochi jam. The hedonic test indicated that panelists generally liked the pineapple jam filling for mochi in terms of taste, aroma, color, and texture.
