Abstract

Organic waste management, such as banana peels, remains suboptimal, particularly among school students, which may potentially lead to negative environmental impacts. To address this issue, a community assistance program on eco-enzyme production was conducted for vocational high school (SMK) students with the aim of enhancing their knowledge and skills in processing organic waste into value-added products. The main focus of this community service activity included organic waste management, the eco-enzyme production process, and the impact of educational interventions on improving students’ knowledge and skills. The methods employed in this program consisted of pre-test administration, educational counseling, demonstrations, group-based independent practice, as well as evaluation and reflection. Data were collected through pre-test and post-test assessments, observations, and documentation of students’ practical outcomes. Data analysis was carried out using quantitative descriptive methods to examine improvements in pre-test and post-test scores, complemented by qualitative analysis based on observational data collected during the activity. The results demonstrated a significant improvement in students’ understanding, as indicated by an increase in the average score from 68 in the pre-test to 96 in the post-test. In addition, students successfully produced eco-enzymes of satisfactory quality in accordance with the procedures taught during the training. In conclusion, this program not only enhanced students’ knowledge and practical skills but also fostered greater awareness of the importance of waste management for environmental sustainability.
