Abstract

Fish farmers in the Yogyakarta area mention problem main cultivation fish is expensive cost commercial feed, so that independent-feed will be chosen as solution. Independent-feed still causes problems such as low stability and feed buoyancy. To do enhancement quality independent-feed with giving edible coating. Solution edible coating made with basic waste skin cassava remember production cassava in Indonesia (2018) reached 21 million tons, so more than 4 million tons of skin cassava is waste. There is starch amounting to 44-59% of the skin cassava could used as solution edible coating. Method coating used that is spraying. Data taken covering stability, power buoyancy, and texture feed on treated water use equation mathematical and t-test at 5% level with SPSS26 software. The value of t arithmetic is 4.03 which has a value greater than t table with a value of 1.717 which results in higher stability in the feed treatment than the control feed. The Texture analysis value shows the treatment feed has a lower pressure compared to the control feed because of the effect of the plasticizer layer. both of these causes the pellets to last longer in water.
