The paper presents the effect of additional bioactivators and dosage of goat manure on organic fertilizer made from the waste of cocoa pod husk in Malang District. The experimental design of this study is a Randomized Block Design (RBD) with 2 factors (variation of bioactivators and dosage of goat manure) with 4 replications. For the statistical evaluation of a two-way analysis of variance (ANOVA) at the significance level of 0.05. If the significance of F was less than 0.05, pairwise comparisons were made using the Least Significant Difference (LSD) test at a significance on level of 0.05 (α=5%). The results showed that the waste of cocoa pod husk could be used as an organic fertilizer after composting for 32 days, where the application of bioactivator and dosage goat manure did not show a significant effect on parameters of pH, temperature, moisture content, N-total content, and C/N ratio, but for the parameter of C-organic, it showed that the addition of bioactivator and goat manure has very significant interaction. The best treatment of this research on the treatment of bioactivator Decoprima types and dosage of goat manure 1.0 kg (B3K2) with the resulting pH 7.31, temperature 32.53°C, the water content of 32.51%, C-organic 25.62%, N-total 1.95, C/N ratio 13.16 with shrinkage 31.8%. Processing of organic fertilizer from waste cocoa pod husk can increase the value and meet the quality standards of the Minister of Agriculture of the Republic of Indonesia with number 261/KPTS/SR.310/M/4/2019 and Indonesian National Standard 19-7030 2004.
