| Summary: | The purpose of this research was to tackle the increase amount of sludge being produced every year from
wastewater treatment plant and to figure out an alternative form of way to produce commercial protease
enzyme. The wastewater sludgecake from Indah Water Konsortium Sdn Bhd was used as the substrate media
and a potential low-cost media for protease enzyme production. For the design of the experiments, eleven
parameters were screened and the three most significant parameters were found as glucose, tween-80 and
moisture content which were further optimized using Face Centered Central Composite Design to find the
optimum condition for the production. The optimization study showed that 4% glucose(w/v), 2% tween-80(v/v)
and 40% moisture Content(w/v) produces the highest protease activity of 92.141 U/ml. The analysis of variance
(ANOVA) also showed that the optimization model was significant with p < 0.0038 and R
