摘要：The purpose of this research was to know the optimization of incubation time in the production of protease and amylase by bacterial isolates of anchovy Stolephorus sp. paste origin. This research was conducted in two stages, namely the growth of bacterial isolates measurement and determination the optimum time production of the enzyme protease and amylase. Testing conducted include the test proteases and amylase enzyme activity and protein levels of each of these enzymes. The data will be analyzed test results are descriptive. There are 4 bacterial isolates, where 2 isolates, which is a proteaseproducing bacteria isolates that is P2 and P4, and 2 isolates, which is the amylase-producing bacteria that is A2 and A4. The activity of the protease optimum occurs at to-36 hours to isolate P2 of 0.073 U/mL with a specific activity of 1.632 U/mg and isolates P4 that is 0.057 U/mL with a specific activity of 4.91 U/mg. Whereas amylase activity, optimum occurs at to-36ohours for A2 isolates of 0.360 U/mL with a specific activity of 7.73 U/mg and activity of amylase optimum on A4 isolates of 0.239 U/mL with a specific activity of 5.224 U/mg.
