Shrimp waste fermentation technology is a practical alternative solution; the results are preferred by livestock and can improve the nutritional quality to affect the quality of the ration. The provision of rations with good quality protein can affect the growth rate and development of local chickens. Local chicken is one type of local poultry that can produce eggs and meat so that the community widely cultivates it. The purpose of the study was to obtain the level of use of fermented shrimp waste in the ration that produced the best local chicken performance. The study used 125-day old local chicken chickens, divided into 25 cage units and each cage unit consisted of 5 chickens. Chickens were reared for eight weeks. The study used an experimental method with a completely randomized design, five types of ration treatments, namely R0 (the ration without the use of fermented shrimp waste), R1 (the ration containing 5% fermented shrimp waste), R2 (the ration containing 10% fermented shrimp waste), R3 (the ration containing 15% fermented shrimp waste), and R4 (the ration containing 20% fermented shrimp waste). Each treatment was repeated five times. Data were analysed using ANOVA, and differences between treatments were performed using Duncan's Multiple Range Test. The results showed that fermented shrimp waste (Bacillus licheniformis, Lactobacillus sp., and yeast Saccharomyces cerevisiae) up to 10% in the ration formula could utilize fish meal, and improve growth performance, as well as promote the best final weight in local chickens. Fermented shrimp waste can be used up to a level of 20% in the ration formula without affecting the performance of local chickens.
