Utilization of maggot (Heermetia illucens) as raw material for feed on the physical quality of fish feed

Objective: The aim of this research is to determine the use of maggot (Heermetia illucens) as a raw material for feed on the physical quality of fish feed. Material and method: This research was carried out in September-November 2023. The experimental design in this research was to make maggot caterpillar flour, fish meal, corn flour and tapioca flour, then formulated using the trial and error method. The treatments tried included treatment A with 45% fish meal, 35% maggot meal, treatment B with 50% fish meal and 30% maggot meal, treatment C with 55% fish meal and 25% maggot meal and treatment K with 0% fish meal and maggot meal. 80%. All treatments each added 16% corn flour and 4% tapioca flour as feed adhesive. Physical test analysis includes tests for feed hardness, solubility and feed color. Results: The results of the research show that regarding the solubility of the feed, maggot can be used as an ingredient in making feed because it has good attractiveness for the test fish, even though commercial feed shows better results. Regarding solubility, feed made from maggots has good solubility, even treatments B and C showed better results than the control treatment. The hardness level of the feed is better than the control treatment, which means that the fish can use the feed well because it has a low hardness level and suits the fish's needs. Conclusion: The use of Maggot (Heermetia illucens) as a feed ingredient can be used as a raw material for feed because it can have a positive influence on the physical quality of fish feed such as the attractiveness of the feed to fish, the solubility of the feed, the hardness level of the feed, and the color of the feed.
