Abstract
Cow’s feces originated from farms dairy an organic waste that can causing an environmental pollution therefore need to be process to make something such as fertilizer using activators that help the decomposition process run faster. Activator used in this experiment is Stardec. Decomposition of cow’s feces becoming organic fertilizer by mixing cow’s feces with Stardec activator. Ratio of cow’s feces weight (Metric Ton) by weight (Kilogram) of Stardec activator is 1:0; 1:1; 1:2; 1:3; 1:4. Thereafter, add the anorganic fertilizer (Urea, KCl, SP-36) and limestone to the mixture each about 2,5 kilograms after that cover the mixture with plastic wrap and make some holes with bamboo. The allowing the mixture for 3 weeks to make an analysis on temperature and C/N ratio for 3 days. The experiment result shows that process of composition for 21 days on Stardec with 10 kg weight to produce organic fertilizer consist about 15,23% organic carbon, 0,84% total nitrogen, 18,13 C/N ratio. These result meet the quality standards set by the Minister of Agriculture No.70/Permentan/SR.140/10/2011. Keywords : stardec, cow’s feces, organic fertilizer, decomposition, C/N ratio
