Abstract : The price of commercial feed, which is becoming more expensive, has caused the need for alternative fish feed with the same quality but at a lower price. The feed costs are the most significant component in catfish farming. The larvae of Black Soldier Fly or maggots can be used as an additional alternative feed. This study aimed to determine the efficiency of feed costs by providing additional maggot feed-in Sangkuriang catfish cultivation. Furthermore, the effect of giving maggots was also analyzed in the feasibility business of catfish farming. The results showed that the most efficient feed cost was a combination of 50% commercial feed in the form of pellets and 50% maggots. This combination of feed reduced costs by IDR 675 / kilogram of feed. The business feasibility indicator of this combination of feed showed better results than the use of pellets only. NPV increased to IDR 1,831,038, IRR of 64.41%, Net B / C with a value of 2.36, and the Pay Back Period improved at 15 months. Thus, the best recommendation for Sangkuriang catfish cultivation is a combination of 50% commercial feed and 50% maggots
