During production periods, abundant by-products of the dead bird in broiler industries require an adequate alternative treatment to prevent harmful effects from direct disposal in the open environment. This study evaluates compost's efficiency and physicochemical properties produced from coped dead broiler carcass with cattle manure and rice straw. Four treatments were conducted, which illustrated different proportions of broiler carcasses 0% (P0), 1% (P1), 3% (P2), and 5% (P3) in the cattle manure compost. The physicochemical analysis, including color, odor, texture, moisture content, total organic carbon, total organic (C) matter, total nitrogen (N) content, C/N ratio, phosphorus (P), and Potassium (K), were defined in this research. The result of the physicochemical composition on this research has filled up the Indonesian compost standard SNI:19-7030-2004 except in the total N, total P, and C/N ratio content.
