This study aims to determine the effect of variations in the feed formulation Black soldier fly (BSF) Hermetia illucens consisting of fish and vegetable waste on the nutritional content of BSF larvae. This type of study is an experiment using 4,000 BS larvae that have entered the instar phase two. The maintenance of BSF larvae is carried out for 15 days. Feeding is carried out once in 2-3 days. This study used a Randomized Group Design (RAK) with 3 treatments and 3 repeats. Treatment A is 10% fish waste: 90% vegetable waste, B is 20% fish waste: 80% vegetable waste, C is 30% fish waste: 70% vegetable waste. The observed parameters, namely the content of nutrients in the body of BSF larvae was analyzed using proximate analysis. The data from the proximate analysis were analyzed using analysis of variance (ANOVA) and Duncan's advanced test with a confidence level of 95%, the results of the study showed that the behavior of C with 30% of fish waste and 70% of vegetable waste gave the best results with the highest protein content compared totreatments A and B. to the nutritional content of the larvae of BSF Hermetia illucens.
