Abstract

Improper waste management at SDN Petompon 3 Semarang has led to inadequate sanitation and a lack of environmental awareness among students. This community service initiative aimed to address these issues by educating 5th and 6th-grade students on organic waste processing through the utilization of Black Soldier Fly (BSF) larvae. The program introduced a hands-on approach where students learned to sort, manage, and convert organic waste into value-added products such as animal feed and organic fertilizer. Additionally, the program incorporated entrepreneurship training, equipping students with basic skills in packaging, branding, and marketing to promote sustainable small-scale enterprises. The activities included stakeholder coordination, infrastructure preparation, environmental education, and product processing workshops. Results showed improved student participation, increased environmental knowledge, and measurable growth in maggot biomass and waste decomposition rates over 30 days. This integrated program not only enhanced environmental cleanliness at the school but also fostered early environmental stewardship and entrepreneurial skills among students, contributing to sustainable waste management and community empowerment.

Abstract

This community service program aims to optimize the use of Carica (Carica pubescens) waste into liquid organic fertilizer through bioconversion techniques, while simultaneously increasing the capacity of MSMEs and farmer groups in Kejajar District, Wonosobo. Activities include outreach, training, and mentoring in the production of liquid organic fertilizer on a household scale using simple technology based on decomposer microbes. The results of the community service show an increase in partners' knowledge and skills in Carica waste fermentation techniques, as well as in the production of liquid organic fertilizer with physical, chemical, and microbiological properties suitable for organic farming. Analysis shows decrease in pH and color changes, a distinctive fermentation odor, and increases in nutrient content (N, P, K), along with variations in substrate concentration. In addition, participants received mentoring on digital marketing strategies to increase the product's economic value. This program contributes to reducing Carica industrial waste, providing alternative organic fertilizers, and empowering local communities to improve welfare based on regional potential.
