The aim of this research was to examine the effect of fermentation time by Aspergillus niger on peanut shells ammoniated on VFA and NH3 production. The research was allocated in a completely randomized design with 4 treatments and 4 replications. The treatments were fermentation process of 0 days (T0), 5 days (T1), 10 days (T2) and 15 days (T3). The results showed that fermentation process with A. niger on the ammoniated peanut shells increased (p<0.05) the VFA and NH3 production. In an incubation time of 15 days, the highest VFA and NH3 production waas obtained. The average production of VFA were T0=153; T1=188; T2=193 and T3=203 mM respectively. Average of NH3 production in this study were T0=2,89; T1=3,61; T2=3,74 dan T3=3,90 mM respectively. It was conclusded that the fermentation process with A. niger on peanut shells ammoniated increased the VFA and NH3 production. The 15 days of fermentation process was the best time which produced the highest of VFA and NH3 production.
Key words: Aspergillus niger, NH3, peanut shells, VFA
