Abstract:
The production of batik generates a large volume of wastewater with complex nature
and characteristics such as high temperature, pH, BOD, COD, and TSS. In Jababeka Industrial
Estate, Wastewater from batik industries is treated by going through a facultative equalization
tank before going to the next treatment units. Hypothetically, by optimizing the facultative
equalization tank, it will improve the effluent quality and increase COD and Ammonia's
removal efficiency. This research used 4 microbial products that are commercially available
and can be applied easily in real-life operating conditions. The study aimed to determine the
effect of bacteria addition and its removal efficiency for batik wastewater effluent from batik
industries in Jababeka Industrial Estate. the parameters measured were pH, concentration of
COD and ammonia. The addition of bacteria reduced COD and Ammonia concentration in the
wastewater and changed the wastewater's pH and color. The result indicates that for high COD
and ammonia loads, the M-Aerobic bacteria is the best type of bacteria with a removal
efficiency of 63.39% and 99%, respectively. However, ANOVA analysis indicates that there is
no statistically significant difference between the treatment groups. It is recommended for this
experiment to be repeated in a continuous reactor.
