This study used a Randomized Group Design (RBD) with 1 factor, which is the variation in the ratio of organic waste with 5 levels: fish bone meal (TI) 50% coconut pulp (AK) 15% rice bran (B) 35%, TI 60% AK 10% B 30%, TI 70% AK 5% B 25%, TI 80% AK 5% B 15%, and commercial feed (Control). he observed variables include protein content, fat, moisture, ash, crude fiber, carbohydrates, and feed diameter. The results showed that variations in the ratio of organic waste had a significant effect on the protein, fat, moisture, ash, crude fiber, carbohydrate and feed diameter, with the tested met the requierements of SNI 7473 (2009). The best treatment that produced variations that match the characteristics of SNI 7473 (2009) and close to the control was TI 80% AK 5% B 15% with characteristic values of protein content 21.29%, fat 10.61%, water 8.67%, ash 12.82%, crude fibre 22.3%, carbohydrate 46.60%, and feed diameter 5.20 mm.
