Abstract

This research focuses on reducing waste to achieve clean technology by applying a combination of enzymatic and chemicals during the unhairing process. The method applied is to reduce the use of Na2S and NaHS by 0.3% from 2.7% Na2S to 2.4%, 1,5% NaHS to 1.2%, and add a protease enzyme, namely centrobate 1000 LVU by 0.25%. The result based on the trial showed that the addition of an enzyme of 0.25% could remove the hair perfectly and reduce the level of swelling. Moreover, it can produce pickled skin with the same quality. The resulting production waste experienced a significant decrease in COD by 18%, while the BOD was less effective at 1.4%.
