This study aims to determine the potential of microorganism in processing of mixed sheep feces and rice straw, used as a starter in the preservation of forage feed. The method is, in the 1 st phase with 3 treatments of carbon and nitrogen ratio with 6 repetitions and the 2 nd phase with 3 treatments of molasses in the base medium, which are grouped in dry matter content with 6 replications. The results of the 1 st phase showed the preferred treatment of T2 (C/N ratio 30) yielded an initial number of bacteria of 2.87 x 10 14 cfu/g and fungi 9.6 x 10 13 cfu/g, and decreased into 4.2x 10 10 cfu/g and 3.7 x 10 11 cfu/g, respectively. At the end of initial degradation, bacteria identified were Bacillus sp and fungi identified were Aspergillus niger , Aspergillus glaucus , Aspergillus terreus, Rizophus sp. The results of the 2 nd phase showed that the highest bacterial colonies were achieved in T2 with DM3 of 38 x 10 6 cfu / ml and the bacterial consortium identified were Bacillus sp and Lactobacillus sp. The number and types of bacterial consortium isolated and identified in the liquid medium can be used as a starter in the preservation of forage feed.
