ABSTRACT
Untreated liquid waste from tofu production, if directly disposed of without any treatment, will cause pollution. Therefore, it is necessary to treat the waste before it is discharged into the environment. The process used in the treatment of liquid tofu waste is biological treatment, utilizing the symbiosis of microalgae and bacteria to reduce pollutant parameters. This is achieved through the use of Rotary Algae Biofilm Reactor (RABR) technology, which involves both attached (biofilm) and suspended cultivation systems. The microalgae used in the process are Chlorella sp. and the bacteria used in the study were derived from indigenous microorganisms (IMOs) resulting from the fermentation of unused kitchen waste. These IMOs contain aerobic microorganisms with a Volatile Suspended Solids (VSS) density of more than 3000 mg/l. The research involved varying the addition of kitchen waste MOL with bacterial density of 20 ml (VSS 3950 mg/L), 40 ml (VSS 4480 mg/L), and 60 ml (VSS 5170 mg/L), along with contact times of 1, 3, and 5 days. The results of the study showed that the addition of 60 ml of kitchen waste IMOs with VSS of 5170 mg/L on the 5th day resulted in COD removal efficiency of 88.89% and NH3 removal efficiency of 91%, with a total density of suspended and attached (biofilm) Chlorella sp. cells at 2.39 x 106 cells/ml and 2.47 x 106 cells/ml, respectively.
Keywords: Indigenous microorganisms (IMOs), Chlorella sp., Rotary Algae Biofilm Reactor (RABR), COD, tofu liquid waste
