<![CDATA[Background: The main factor influencing the success of fish farming is the quality of the feed given to the fish. However, it should be noted that some commercial fish feeds contain chemicals that can harm fish health. Methods: Proximate tests were carried out with three formula designs, namely formulas A1, A2, and A3, with a ratio of fermented coconut dregs flour and earthworm flour, respectively 1:2, 2:1, and 1:1. Feed sensory tests were also carried out, which included color, aroma, and texture of organic fish feed. The data collected was then analyzed using IBM SPSS Statistics version 23. Results: Proximate test results were the average protein content of fish feed formulas A1, A2, and A3 respectively 10.85%, 16.28%, and 13.07%, while the average carbohydrate content of formula fish feeds A1, A2, and A3 respectively 30.04%, 26.54%, and 27.91%. Meanwhile, the sensory test results for the color of formula feed A1, A2, and A3 had scores of 1.70, respectively, 3.70, and 2.45. The results of the sensory test for the aroma of formula feed A1, A2, and A3 had scores of 2.90 respectively, 3.45 and 3.05, while the results of the sensory test for the texture of formula feed A1, A2, and A3 had scores of 2.20 respectively; 3.40; and 3.30. Conclusions: The most effective feed formula given to fish is formula A2, which has the highest protein content, reaching 16.28%, and carbohydrate content, 26.54%.]]>
