【 摘 要 】

Utilization of organic waste as raw material for fish feed can save the cost of fish feed production. This study aimed to utilize organic waste as raw materials for making fish feed. The study was conducted at the Polytechnic Indonesia Venezuela during four months (November 2014 -February 2015). This research comprised 5 treatments with 3 replications, namely: P1 (commercial feeding), P2 (feeding with 5% organic waste formulation), P3 (feeding with 25% organic waste formulation), P4 (feeding with 50% organic waste formulation) and P5 (feeding with 75% organic waste formulation). Clarias gariepenus was fish species used during the observation with size 2 g/tail. Fish are cultivated in soil ponds (2x2 m2) with density 500 fishes/pond for 3 months. Parameters measured were growth and survival rate. The results showed that the best growth rate obtained at treatment P2 (114.2 g) and the highest survival percentage was on treatment P1 and P2 (> 60%). Conclusion, the addition of the proportion of organic waste as much as 5% in making fish feed with protein 34.19% produces the best growth.
