Hydrolysis enzymes can be produced from Aspergillus niger using solid state fermentation method. This research aimed to understand the fermentation efficiency of A. niger with different variety of the biomass waste substrates, i.e. rice husk, sugarcane bagasse and corn cob, to produce alpha-amylase and beta-glucosidase. The optimum fermentation time for each substrate was 6 days. The highest activity unit for alpha-amylase and beta-glucosidase were 81.86 U/ml and 95.02 U/ml using substrate corn cob respectively. Activity units were 73.94 U/ml and 82.35 U/ml measured for dry alpha-amylase and dry beta-glucosidase respectively. This dried enzyme was stable for hydrolysis process at 30-50 degrees C.
