Production of Fish Feed from Soy Residue and Shrimp Waste using Tapioca as Binding Agent

Abstract

The most used fish feed in cultivation activities is commercial feed that spends most of total cultivation cost. One of the effort to solve this problem is providing homemade fish food. The pellet based on local waste raw materials can reduce dependency of commercial fish feed. One of the local wastes that can be used is soy residue and shrimp waste. Tapioca is used as a binding agent for fish pellet. The aim of the research was to study the effect of raw material composition and binding agent concentration on proximate value, performance and mechanical strength. The research was conducted in several steps such as raw materials pretreatment, the experiment of raw materials and binding agent formulation, mixing, extrusion, prilling process, drying process, and product analysis (proximate and performance analysis). There are five formulations of raw materials and three different of formulation on binding agents. The drying process was done in 50°C and the product was then analyzed. The result shows that formulation with 30% soy residue, 60% shrimp waste and 10% binding agent resulted in a product with good proximate value (11.23% moisture content, 17.64% ash, 1.33% fat, 25.10% fiber, 29.54% protein). Increasing the percentage of binding agents resulted in higher mechanical strength and higher performance.
