Penerapan Teknologi Tepat Guna Pengolahan Limbah Perikanan menjadi Nutrisi Tanaman dan Pupuk Organik Implementation of Appropriate Technology for Fishery Waste Processing into Plant Nutrients and Organic Fertilizer

Abstract

Fish processing activities generate organic waste, including fish scales and processing residues, which may cause environmental pollution if not properly managed. However, these wastes have the potential to be used as plant nutrients and organic fertilizers, adding economic value. This community service program aimed to improve the knowledge and skills of members of the Aceh Fish Jelly Production Cooperative in processing fishery waste by applying appropriate technology based on community empowerment. The program was implemented through socialization, training, demonstrations, hands-on practice, and mentoring. Fish scales were processed into calcium powder for plant nutrition, while fish processing residues were converted into liquid organic fertilizer through a fermentation process. Evaluation was conducted using initial and final assessments as well as observations of participants’ practical skills. The results showed an increase in the average score from 58.60 in the initial assessment to 82.93 in the final assessment, representing a 41.52% improvement. In addition, all participants achieved a high skill category after completing the training and were able to independently produce calcium powder and liquid organic fertilizer from fishery waste. The application of appropriate technology for processing fishery waste was effective in enhancing community knowledge and skills, reducing the potential for environmental pollution, and promoting the conversion of waste into useful, economically valuable products.
