The development of the aquaculture industry increases fish feed needs. On the other hand, the manufacture of high-protein fish meal has limited raw materials. Hermetia illucens larvae can be used as an alternative protein source for fish feed because it has a high protein content. This study aims to determine the potential utilization of H. illucens larvae fed with a mixture of organic waste from fish offal, tofu pulp, and banana peel as an alternative protein source for fish feed. Potential utilization of H. illucens larvae was determined based on larval growth and development, WRI, ECD, and proximate analysis of H. illucens pupae. 7-dayold larvae were treated with organic waste feed in 4 treatments, namely control, high, medium, and low protein feed (60 mg/larva/day). Data were analyzed statistically using One-Way ANOVA and Post-Hoc Tukey test (P <0.05). The results showed that larvae with low protein feed treatment has the best growth (growth rate 3.47 mg/larvae/day; body weight 65.69 mg/larvae), the fastest development towards the prepupa (19 days), and the highest feed reduction and conversion (WRI 1.93; ECD 12.92%). The highest protein content is found in larvae with moderate protein feed treatment (50.35%), the highest carbohydrate content (27.59%) is found in larvae with high protein feed treatment, and the highest fat content (21.37%) is found in larvae with low protein feed treatment. From this study, it can be concluded that H. illucens larvae are able to reduce and convert a mixture of organic waste from fish offal, tofu pulp, and banana peel, and have the potential to be used as alternative protein sources for fish feed.
