Abstract

Household waste is one of the major contributors to environmental problems in densely populated areas, including Kenangan Village in Percut Sei Tuan District. Limited waste management systems have led to the accumulation of organic waste, environmental pollution, and declining public health. At the same time, the rising cost of commercial animal feed has become an economic burden for low-income families. This community service program aims to provide an integrated solution through training on Black Soldier Fly (BSF) larvae cultivation to convert organic waste into animal feed and organic fertilizer. The implementation methods included lectures, discussions, demonstrations, hands-on practice, and field mentoring. The results indicate an improvement in the community’s understanding of organic waste processing, significant reduction of organic waste volume, and the production of maggot culture as livestock feed and organic fertilizer. In addition, participants were motivated to initiate small businesses based on maggot production and its residue. This program has proven to be effective as a circular economy solution that integrates waste management, household economic improvement, and community empowerment. The activity is recommended for broader and continuous implementation.

Abstract

This community service program aims to enhance elementary school teachers’ competence in utilizing PhET Interactive Simulations as a virtual laboratory tool in science learning, particularly on the topic of “Changes in the States of Matter.” The program employed a workshop-based training model combined with two weeks of guided mentoring to ensure effective classroom implementation. The activities included technical training on operating PhET simulations, pedagogical training on designing inquiry-based lesson plans (RPP) and student worksheets (LKPD), independent practice sessions, and evaluation through pretest–posttest assessments and classroom observations. The results indicate a significant improvement in teachers’ technical and pedagogical skills, demonstrated by their ability to operate simulations independently, develop inquiry-oriented LKPD aligned with PhET features, and integrate simulations into structured inquiry learning steps. Classroom implementation further showed that PhET-based LKPD effectively increased students’ engagement, motivation, and conceptual understanding. In addition, post-training mentoring supported teachers in overcoming technical challenges and promoted sustainability of virtual laboratory practices at the school level. Overall, the program successfully strengthened teachers’ instructional capacity and supported more active, exploratory, and inquiry-based science learning aligned with the principles of the Merdeka Curriculum.
