Research has been conducted to determine the ability of the bacterial consortium in bioremediation of Cimuka River in terms of reduction in BOD, COD, Ammonia, and TSS. The method used in this study is experimental method with Complete Randomize Design (CRD) consist of 2 factors and 3 replications. The first factor were the type of indigenous of bacteria onsortium (K), the consortium of bacteria are: (k₁) microbial consorsium Bacillus coagulans, Bacillus pumilus, Bacillus subtilis dan Nitrosomonas sp., (k₂) microbial consorsium Bacillus pumilus, Bacillus subtilis, Paenibacillus amylolyticus dan Nitrosomonas sp., (k₃) microbial consorsium Bacillus coagulans, Bacillus subtilis, Paenibacillus amylolyticus dan Nitrosomonas sp., (k₄) sterilized water river without indigenous bacterium neither additional bacterium., (k₅) water river with existing indigenous bacterium. The second factor is Retention time (T) consist of 8 stages, i.e.: (t₀) day- 0, (t₁) day- 4, (t₂) day-8, (t₃) day-12, (t₄) day-16, (t₅) day- 20, and (t₆) day- 25. The results obtained indicated that consortium of Bacillus subtilis, Nitrosomonas, Bacillus pumilus and Bacillus circulans (k₁) is capable of effectively reducing BOD values of 77.3 %, COD 76.7 %, Ammonia 81.8%, and TSS 79.5%.
