Medan — Household organic waste, often considered useless, can actually be transformed into a multifunctional liquid that supports environmental cleanliness. This is the focus of a scientific article written by Efbertias Sitorus and a research team from Universitas Methodist Indonesia and Universitas Sumatera Utara. Published in 2026 in the Jurnal Pengabdian Masyarakat Formosa (JPMF), the article highlights eco-enzyme production from household organic waste as a simple yet effective solution for sustainable environmental sanitation.
The community service program took place on April 10, 2026, at the Indonesian Methodist Church, Wesley Residence Congregation, in Medan, North Sumatra. Around 30 church members participated in the training, which combined education, live demonstrations, discussions, and short mentoring sessions. The program emphasized that households are the starting point for better waste management.
Efbertias Sitorus and the team explained that household organic waste remains a major environmental challenge. Fruit peels, vegetable scraps, and other kitchen waste are often discarded without separation. However, when properly managed, these materials can be converted into useful products for daily household needs.
Eco enzyme is a fermented liquid made from organic waste, brown sugar, and water in a 1:3:10 ratio. Common ingredients include pineapple peels, onion skins, lemongrass, lime, and turmeric. According to the researchers, the process is simple, affordable, and accessible for anyone to practice at home.
The training began with lessons on the importance of sorting organic waste. Participants then observed the step-by-step process of cutting materials, mixing them with water and sugar, and storing them in fermentation containers. They also learned about gas pressure release during the early fermentation process, which is essential for safety and successful results.
Participants responded enthusiastically, asking questions about suitable ingredients, fermentation duration, signs of successful fermentation, and practical applications of eco enzymes. Their engagement showed that household-based waste management is highly relevant to daily life.
Efbertias Sitorus from Universitas Methodist Indonesia emphasized that environmental behavior starts with changing perspectives on waste. Organic waste should no longer be seen as useless trash but as a resource that can be reused. This mindset shift is at the core of sustainable environmental education.
Observations showed that all activity targets were achieved. The materials were delivered successfully, demonstrations ran smoothly, participants actively engaged, and many committed to trying eco-enzyme production independently at home. This confirms that hands-on learning is more effective than theory alone in community education.
The benefits of eco enzyme go beyond waste reduction. The fermented liquid can be used for cleaning floors, drains, and other household sanitation purposes. In terms of sanitation, better organic waste management helps reduce unpleasant odors, prevent insects, and maintain family health. This makes eco enzyme a practical household solution with direct benefits for quality of life.
More broadly, this study shows that community-based environmental education can be an effective strategy for building sustainable clean-living habits. When families start sorting and processing their own waste, the impact extends beyond the home and into the wider social environment. This model could be applied in schools, women’s groups, and other community organizations.
Efbertias Sitorus and the team concluded that long-term success depends on follow-up support and household monitoring. Continued mentoring is essential so that the knowledge gained does not remain theoretical but develops into a lasting lifestyle habit. In this way, organic waste management can become part of Indonesia’s healthy living culture.
