The Community Service Program of Universitas Pelita Bangsa (UPB) in Karangrahayu Village was carried out as a form of community engagement through food diversification innovation based on catfish. Previously, Karangrahayu Village had no significant fisheries potential. However, with the initiative of the Village-Owned Enterprise (BUMDes), catfish ponds were established to support food security while boosting the village economy. The production of catfish has so far been limited to sales in fresh form or simple processing, resulting in relatively low added value. To address this issue, UPB Community Service students introduced marinated catfish products as a food diversification solution to increase processing variety, extend shelf life, and create new marketing opportunities. The program also aimed to provide education on modern processing techniques, enhance community skills, and encourage village economic empowerment. The implementation methods included a survey of local raw material potential, marination product development, and business opportunity analysis. The results show that marinated catfish has good consumer acceptance in terms of taste, aroma, and texture, as well as promising market prospects due to the utilization of local resources with low production costs. Therefore, the development of marinated catfish can increase added value, create job opportunities, and strengthen MSMEs in Karangrahayu Village.
