Objective: The research aims to analyze the chemical content of making fish food by using maggot as a substitute for fish meal as a protein source to improve the quality of fish feed. Material and method: The research method used was an experimental method with 4 treatments and 3 replications. Treatment A is feed consisting of 45% fish meal, 35% maggot meal, 16% corn meal, and 4% tapioca flour; treatment B is feed consisting of 50% fish meal, 30% maggot meal, 16% corn flour, and 4% tapioca flour; treatment C is feed consisting of 55% fish meal, 25% maggot meal, 16% corn flour, and 4% tapioca flour; and control treatment (k) is feed consisting of 0% fish meal, 50% maggot flour, 16% corn flour, and 4% tapioca flour. Results: The results of the research show that the overall water content of the feed produced is low. Regarding protein content, the highest protein content was in the control treatment. The use of maggot flour in feed has the lowest ash content. Regarding fat content, the higher the dose of maggot flour, the lower the fat content of the fish feed. All treatments tested had a lower carbohydrate content than the control treatment. Conclusion: The use of maggot meal as a substitute for fish meal in this research for making fish feed can support chemical feed quality, which contains water, protein, fat, ash, and carbohydrates according to fish needs.
