Quality of Compost Combination of Feces from Cattle and Laying Hens using Rice Waste as a Decomposer Media

The need for compost as a source of organic fertilizer is increasing along with the increasing human food needs. Compost is a collection of organic materials that have undergone a decomposition process so that they change shape and are no longer recognized in their original form. Compost is black in color and odorless. The purpose of the study was to determine the quality of compost produced from a mixture of cattle feces and laying hens using rice waste as a medium for decomposers. The study was designed using a completely randomized design (CRD) factorial pattern, 3 x 2 with 3 replications. Factor I is a combination of feces (cattle:laying hens); (1) M1 (100%:0%); (2) M2 (50%:50%) and (3) M3 (0%:100%). Factor II is the level of decomposers (1) D1 (1%) and (2) D2 (5%). Parameters measured were color, pH, compost temperature. The results showed that the different combinations of feces from cattle and laying hens had a significant effect (p<0.01) on the color value, pH and temperature of the compost. The different levels of decomposers significantly affected (p<0,01) on the pH value and temperature of the compost, but did not affect (p>0.05) to the color value of the compost. The results of the study concluded that the application of a combination of M2 (cattle:laying hens) feces (50%:50) with a decomposer level of 1% (D1) produced the best compost characteristics and met the requirements set by the government
