<![CDATA[The biomass of the rice harvest is in the form of straw waste produced in one harvest season reaching 25 tons/ha and can be used as raw material for making compost. This research was conducted to determine the effect of different composting pile models of cow manure and straw, and to know the appropriate pile model so that the composting process of cow manure and straw produces compost in accordance with SNI No. 19-70302004. This study used 3 treatments, namely: P1 (treatment using an open windrow pile model), P2 (treatment using a static pile model), P3 (treatment using a Chinese pile model). The materials used in each treatment have a weight of 35 kg with a ratio of straw and cow manure of 2: 1. The observed parameters are pH, moisture content, temperature, nitrogen, carbon, and C/N ratio. The composting process with P3 treatment using the china model pile treatment took 48 days, P2 treatment days using a static pile was take 51 days and P1 using an open windrow pile was take 45 days, the results of composted straw and cow manure on the three treatments had met the SNI No. 19-70302004 which is used as a reference for assessing the quality of compost.]]>
