Eco - enzyme or garbage enzyme is a complex solution produced by the fermentation<br />

of fruit wastes, molasses and water at a ratio of 1:3:10. This procedure applied to<br />

reduce the quantity of organic waste that cause the greenhouse effect from landfills.<br />

The waste was collected from pre - consumer which consists of orange, pineapple,<br />

tomato and mango dregs. In this study, the fermentation time of bio catalytic activities<br />

of the eco - enzymatic was investigated. This enzyme possessed amylase, lipase and<br />

protease activities. The activities for each enzyme increase after three months<br />

fermentation. The percentage of chemical oxygen demand (COD) for this enzyme<br />

decreases after 3 months fermentation process and continue decreasing after<br />

undergoing 5 months fermentation process. This condition of enzyme activities proves<br />

that the longer the enzyme was kept, the effectiveness of enzyme increased such as<br />

for further wastewater pre - treatment.<br />
