Abstract

Coffee husk waste is one of the largest agro-industrial byproducts, often underutilized and contributing to environmental problems. Converting this waste into liquid organic fertilizer (LOF) offers a sustainable solution for waste management and agricultural productivity. This study aimed to evaluate the physicochemical characteristics of coffee husk LOF and its effect on corn seed germination and early growth. Fermentation was carried out anaerobically for two months using EM4 as a bioactivator and molasses as a nutrient source. The resulting LOF showed favorable properties, including a neutral pH, a sweet-acidic odor, a dark brown color, and a viscosity close to that of water, which makes it easy to apply. Nutrient analysis showed nitrogen (1.57%), phosphorus (0.14%), and potassium (0.23%), totaling 1.94%. These values indicate that the N-organic content meets the minimum requirement, while the total NPK is slightly below the Indonesian National Standard (2-6%). Application of LOF at concentrations of 0.3-0.5% (v/v) significantly accelerated germination and increased root length, while shoot height and leaf number were not significantly affected. The findings demonstrate that coffee husk waste can be transformed into LOF with acceptable quality and positive effects on early plant growth. Further optimization of fermentation conditions and nutrient enrichment is recommended to meet full quality standards and broaden its application potential in sustainable agriculture.

Abstract

Peron Village is one of the local coffee centers that produces abundant post-harvest waste in the form of coffee grounds and husks. So far, this waste has not been optimally utilized and has the potential to pollute the soil, increase organic pollution, and reduce the quality of the rural environment. This condition calls for innovation based on the circular economy. The hypothesis of this study is that the involvement of young people through a social entrepreneurship approach in coffee waste management can create environmentally friendly innovations while strengthening local economic resilience. This study uses a descriptive qualitative method with in-depth interviews, observation, and documentation techniques, as well as validation through source and method triangulation. Research informants included members of the Karang Taruna youth organization, coffee farmers, community leaders, and micro-business actors in Peron Village. The results showed that young people played an active role in processing coffee waste into liquid organic fertilizer, cascara, and briquettes. These products not only reduce environmental pollution but also increase soil fertility, open up opportunities for functional food businesses, and provide environmentally friendly alternative energy. The involvement of young people demonstrates their strategic role as agents of change who integrate social, economic, and environmental benefits. The conclusion of this study confirms that coffee waste processing based on social entrepreneurship is an effective youth empowerment strategy, supporting the achievement of SDGs 7, 12, and 15, and has the potential to be replicated in other villages to promote sustainable development.
