Where P1 (Without the addition of Kepok banana peel extract), P2 (Kepok banana peel extract 10 ml/kg feed), P3 (Kepok banana peel extract 20 ml/kg feed), and P4 (Kepok banana peel extract 30 ml/kg feed). The results of the research on the level of fish color brightness were obtained in the P3 treatment with a dose of 20 ml/kg feed and the best absolute weight growth was in P4 with a weight increase of 0.84 g, the best absolute length growth was obtained in P4 with a result of 0.99 cm, and the growth rate the best daily was at P4 with a growth rate of 0.69%. The results of the highest feed conversion ratio were found in P4, namely 21.60. Meanwhile, the best survival was found in P1 and P3 with a percentage of 100%.
