Abstract

Background: Physics education, particularly in mechanical energy topics, often faces challenges such as low conceptual understanding and limited scientific reasoning skills. These issues are frequently associated with the lack of interactive and technology-enhanced learning media that enable students to engage with real-time data and experimental visualization.Aims: The aim of this study is to provide interactive learning media based on the Arduino Uno using an elevator system, evaluate its feasibility, and examine its effectiveness in enhancing students’ scientific reasoning skills, particularly control of variables, hypothetical–deductive reasoning, and learning engagement.Method: This study used the ADDIE process (analysis, design, development, implementation, and evaluation) to conduct research and development (R&D). Data were gathered using needs analysis questionnaires, expert validation sheets, two-tier multiple-choice tests (pretest–posttest), and student response questionnaires. The N-Gain approach was used to examine how students' scientific reasoning abilities improved.Results: The implementation of the developed learning media was followed by a significant increase in students’ scientific reasoning scores, with the average score increasing from 32 on the pretest to 88 on the posttest, resulting in an N-Gain score of 0.82 (high category). Additionally, the developed learning media received very positive student responses (94.6%), indicating high usability and engagement.Conclusion: The implementation of the Arduino-based interactive learning media using an elevator system was associated with improvements in students’ understanding of mechanical energy concepts and scientific reasoning skills, particularly in controlling variables and drawing evidence-based conclusions, while also providing an engaging and technology-supported learning experience.

Abstract

Background: Strengthening renewable energy literacy at the secondary education level is a strategic step toward fostering students’ ecological awareness and environmental conservation skills. Biogas, as an alternative energy source derived from organic waste, holds great potential for integration into hands-on learning to enhance students’ conceptual understanding and scientific skills.Objectives: This community service activity aims to introduce biogas technology through hands-on, practice-based education and to analyze students’ responses to the implementation of environmental learning.Methods: The implementation followed a comprehensive pedagogical framework consisting of lectures, interactive discussions, and demonstrations, complemented by hands-on biogas production practices. The program involved 50 students who actively participated in all learning activities and practical sessions throughout the implementation process. Students utilized simple teaching aids crafted from fruit waste and microbial activators (molasses and EM4), with program efficacy evaluated through pre-tests, post-tests, and student response assessments.Results: The activity resulted in a measurable increase in students’ knowledge and skills regarding waste categorization and organic waste management. Participants successfully demonstrated an understanding of the fermentation process required to convert organic waste into methane gas using simple teaching aids.Conclusion: The integration of practical biogas technology into the secondary curriculum effectively bridges the gap between theoretical ecological concepts and real-world environmental skills. Both teachers and students benefited from the hands-on approach, proving that localized renewable energy innovations are viable tools for enhancing scientific literacy.
