The results of the research showing that the highest level of water lies in P0, the highest pH on P3, organic C was highest on P0, the highest nitrogen on P4, the highest C/N ratio on P3, the highest phosphorus on P3, the highest potassium at P4. It can be concluded that goat feces is more capale to improve the quality of organic fertilizer compared to cow feces.
