Popis:	Waste material has a lot of nutrients needed so that it can reduce the price of fish feed. Waste that can be used includes the scales of Torpedo Scad fish (Megalapsis cordyla), taro leaves (Colocasia esculenta), and water hyacinth (Eichornia crassipes). This research was conducted to obtain the correct composition of the three wastes in influencing the physical properties and composition values of commercial fish feed. Composition values tested include levels of protein, fat, carbohydrates, ash content, and water content. This research method begins by refining the commercial pellets, fish scales of Torpedo Scad, taro leaves, and water hyacinth then filtering them with a 125 mesh sieve. After that, mix the ingredients in the ratio A1 A2 and A3. After that, test the composition value of each comparison. The results of this study indicated that the addition of Torpedo Scad fish scales, taro leaves, and water hyacinth were significantly different (P
