Abstract:
This study is to determine the effect of EM-4 on the result of the characteristics of nutrient macro compost of water hyacinth and to know the quality of compost that is produced based on Standar Nasional Indonesia (SNI), National Indonesian Standard. The process of composting applies one replicate with three treatments (K0, K1 and K2). The method used in this study is experiment research with three treatments that is without EM-4, EM-4 20% and 10%. Grade of nutrients analyzed are C, N, P, K and the method used is thermograph, Kjehdal, Walkey and Black, Bray I, and Morgan-Wolf. Kjehdahl method is used to determine the amount of N. Walkley and Black is used to determine C-organic. Bray I method is used to detect the amount of P and Morgan-Wolf method is used to determine K metal. The result of the study shows that each compost K2, K1 and K0 has grade N: 1,72; 1,58; 1,75, the grade of C-organic: 25,78; 25,23; 28,75, the grade of P: 0,47; 0,54; 0,54 and the grade of K: 2,42;2,53;2,58.
The grade of nutrient obtained is suitable with SNI (standar nasional Indonesia), National Indonesian Standard.
