Abstract


Filter cake and coffee pod are sugarmill industrial and plantation wastes that could potentially be used as organic fertilizer because it contains organic matter and nutrients. However both these wastes can not be directly used as fertilizer because of the element of nutrient not fulfill the standard so it should be composted organic fertilizer first. In this research, filter cake and coffee pod were composted with coffee pod treatment additional variation (0 kg, 2 kg, 2.5kg, and 3 kg) and type of activator variations were Agri Simba and MOL from banana weevil. Then their effects   macro nutrient content of fertilizers (CNPK) will be seen after 30 days of composting. The research was conducted at the Laboratory of Environmental Engineering, University of Diponegoro. The best composting results contained in the composition variation of A2 with 3 kg of filter cake, 2.5 kg of coffee pod and Agri Simba activator that contain macro nutrients C-organic = 21.59%, N-total = 0.91%, P-total = 0.181%, K-total = 0.67% and C/N ratio = 23.82. These results are in accordance with the requirements of SNI 19-7030-2004 except for C/N ratio.
