ABSTRACT
The utilization of organic waste as a raw material for fish feed through fermentation represents an innovative and sustainable approach with the potential to enhance nutritional value while improving cost efficiency in aquaculture production. This study aimed to analyze the proximate composition of fish feed derived from fermented organic waste using Lactobacillus casei and Saccharomyces cerevisiae as probiotic agents. The raw materials included vegetable waste, fruit waste, and fish meal, formulated into two feed variations differing in bran proportion, namely 30% in Feed A and 50% in Feed B. An experimental research design was applied, and proximate analysis was conducted to determine moisture content, crude protein, crude fat, crude fiber, Nitrogen-Free Extract (NFE), and ash content. The results revealed that Feed A contained 4.73% moisture, 5.46% protein, 3.31% fat, 35.69% crude fiber, 33.62% NFE, and 21.92% ash. Meanwhile, Feed B showed 6.39% moisture, 5.83% protein, 1.76% fat, 37.91% crude fiber, 30.95% NFE, and 23.55% ash. These findings indicate that Feed A has a more balanced nutritional composition, characterized by higher fat content and lower crude fiber, suggesting better digestibility and potential feed utilization efficiency. In contrast, Feed B exhibited higher fiber and ash content, which may negatively influence nutrient absorption and feed performance. Overall, the fermentation of organic waste using probiotics demonstrates strong potential to improve the quality of alternative fish feed that is not only cost-effective but also environmentally friendly, supporting sustainable aquaculture practices.
