Today, the increase in freshwater fish processing and mushroom cultivation has led to a significant amount of waste being produced, including fish waste and mushroom waste. This waste cannot have discharged into the river because it can lead to the environmental concerns. As environmental awareness grows, extensive study has been conducted to convert these waste into value-added as the main protein sources for fish feed formulation. The purpose of this study is to investigate the effect of different the ratio of between fish waste, (FW) and mushroom waste, (MW) and fish waste, (FW) and rice bran, (RB) as protein sources in fish meal formulation. Several major procedures have been used in the formulation of fish feed, including the drying and grinding of FW and MW. Formulation process of fish feed into five different ratio samples between FW, MW and RB such as sample 1 (90% FW:10% starch), sample 2 (60% FW:30% RB:10% starch), sample 3 (45% FW:45% RB:10% starch), sample 4 (60%FW:30% MW:10% starch) and sample 5 (45% FW:45% MW:10% starch). The formulated samples were undergoing the fermentation process using EM4 in four days, followed by the pelleting process. Each samples were analysed for protein content, lipid content, ash, and moisture content in order to determine the suitable ratio for fish meal formulation. The highest results for protein and lipid contents are 31.41% and 10.47% respectively. Thus, it could be concluded that the best ratio is in sample 2 that consist of 60% of FW, 30% of RB and 10% of starch.
