The result of this research indicate that by ung stardec have an effect on very real to comparison of C/N, moisture content and rendemen, and give the not real influence to pH of compost. the intensity of inversion have an effect on very real to the substance of rendemen, moisture content and give not real influence to pH and comparison of C/N compost. And the influence of interaction by giving the stardec and inversion give the not real influence to comparison of C/N, pH, rendemen, and moisture content
