This research aims to evaluate the quality of goat feces liquid biofertilizer with chicken excreta addition by aerobic and anaerobic fermentation. The data obtained from the research were statistically analyzed with Completely Randomized Design (CRD) Factorial Pattern with two factors. The first factor was addition level of the chicken excreta (0, 10, 20, and 30%) and the other factor was fermentation treatment (aerobic and anaerobic) condition with 3 replications for each treatment. Fermentation was conducted for 14 days. The observed parameters consisted of the chemical parameter (organic-C, N, P, and K) and the physical parameter (pH, temperature, and the odor). The addition of various level of chicken excreta and fermentation treatments in the process of producing goat feces liquid biofertilizer indicate significantly effect to increase the organic-C, total-N, NH4, P, K, compare with 5 and 10% liquid fertilizer treatment. The best quality of liquid biofertilizer produced by combining aerobic fermentation and the addition of 30% chicken excreta. Generally, chicken excreta able to increase the nitrogen and mineral content, and putting together with aerobic fermentation system of chicken excreta maximum to 30% can avoid overproduction of unpleasant odor.
