Abstract

This study aims to evaluate the effectiveness of Nile Tilapia feed formulation using feather meal as one of the primary ingredients, based on the Indonesian National Standard (SNI). Laboratory tests were conducted to measure the chemical composition of the feed, including ash content, moisture content, fat content, protein content, crude fiber, as well as contaminants such as heavy metals, antibiotic residues, and Salmonella. The results showed that the feed had a protein content of 32.31% and a fat content of 9.13%, both exceeding the minimum standards set by SNI. The ash, moisture, and crude fiber contents were also within safe limits. Additionally, the feed was free from Salmonella and antibiotic residues. However, heavy metals like cadmium (1.5 mg/kg) and mercury (1.69 mg/kg) exceeded the maximum limits recommended by SNI. Overall, the feed has good potential for use in Nile Tilapia farming but requires further control over heavy metal content.

Abstract

This study aims to process chicken feather waste into high-protein feather meal using a completely randomized design (CRD) experimental model. Four processing methods were applied: physical (P1), chemical with 12% HCl (P2), enzymatic with 0.4% proteolytic enzyme (P3), and chemical with 6% NaOH (P4). Proximate analysis included crude fiber, protein, moisture, ash, and fat content. An organoleptic test evaluated the color, texture, and odor of the meal. ANOVA and DMRT at the 5% level indicated significant differences between methods. The chemical method with 6% NaOH yielded the highest protein content (50.1%). Organoleptic data showed that all samples had similar sensory characteristics. The study concludes that the chemical processing method with 6% NaOH is the most effective in enhancing protein content, providing an optimal solution for economically and environmentally utilizing chicken feather waste.
