Abstract

The higher the productivity of the Mamasa coffee plant, the greater the waste produced and if it is not processed it will cause environmental problems. This research aims to produce and characterize the macro nutrient value in compost from Mamasa coffee waste using the microorganism bioactivator EM 4. This research was carried out by mixing coffee waste with EM-4, water and sugar in certain proportions. The composting process lasts for four weeks, with observations every week to trigger physical and chemical changes in the compost produced. The research results showed that the compost produced had good physical characteristics, namely black in color, not lumpy and odorless. Determination of macro nutrient levels in the organic material of Mamasa coffee waste before and after fermentation into compost showed a significant increase in the macro nutrients it contains, namely total organic C 25.59%; organic matter was 43.91%, Nitrogen was 2.53%, P2O5 was 1.95%, K2O was 1.68%, C/N ratio was 9.48 and water content was 24.34%. Thus, Mamasa coffee waste can be processed into high quality compost using EM-4, thereby providing a sustainable solution for managing organic waste and increasing soil fertility.

Abstract

The Farming Club Unit (UFC) is a student organization that focuses on sustainable agriculture through hydroponic cultivation. However, limited business diversification has hindered its economic potential, necessitating innovations to strengthen the institution and increase revenue. One promising solution is the farming of Black Soldier Fly (BSF) maggots as an alternative for organic waste management and sustainable animal feed production. This community service program was implemented using a participatory-educational approach, which included lectures, interactive discussions, BSF farming demonstrations, and independent maintenance practices conducted by participants under the guidance of the service team. Evaluation was conducted using pre-test and post-test instruments, analyzed descriptively, and supported by gain score calculation to measure program effectiveness. The results revealed a significant improvement in participants' knowledge, from an average pre-test score of 31.0% to a post-test score of 95.3%, with an average gain score of 0.92 (in the high category). These findings indicate that the training effectively enhanced the capacity of UFC managers in mastering BSF maggot farming skills. The implication of this program is the creation of opportunities for UFC to diversify its business, generate additional income, and contribute to reducing organic waste generation through sustainable agricultural practices.
