Abstract
Shrimp waste contains protein that binds to chitin and is difficult to digest by poultry, so it is necessary to carry out a fermentation process using Bacillus licheniformis, Lactobacillus sp., and Saccharomyces cerevisiae. This study was conducted to determine the Effect of using fermented shrimp waste products that resulted in the optimal conversion of meat protein, carcass weight, and abdominal fat in native chickens. The method used was a completely randomized design with five feed treatments, namely, feed without fermented shrimp waste (R0), feed fermented shrimp waste with 5% (R1), 10% (R2), 15% (R3), and 20% (R4). Experimental feed was given to 125 native chickens, divided into 25-unit cages, and reared up to 8 weeks of age. The observed variables were feed and meat protein conversion, carcass weight, and abdominal fat weight. The study results concluded that fermented shrimp waste did not affect the value of meat protein conversion and abdominal fat weight. The use of 5-10% fermented shrimp waste in feed produces optimal native chicken carcass weight.

Summary
The need for feed in the livestock industry is essential to support the production results of livestock cultivation. A large number of feed requirements in the cultivation of native chickens makes the cost of providing feed high. The main problem in making chicken feed is protein source feed ingredients, such as relatively expensive fish meal, causing high prices for chicken feed. To overcome these problems, alternative protein sources are needed with high protein content at relatively low prices and are available, such as shrimp waste. In Indonesia, 170 shrimp processing businesses have a production capacity of around 500,000 tons per year. The large availability of shrimp waste in Indonesia has great potential in utilizing waste as an alternative feed ingredient to improve the quality of free-range chicken carcasses
