This study aims to obtain raw materials as an effective carrier for starter inoculum consortium of Bacillus coagulans B. licheniformis, B. subtilis, and Pseudomonas sp. and contact time for bioremediation of polluted water from the river Cimuka. The study was conducted by using the experimental method with completely randomized design (CRD) with two-factor factorial 9×9. The first factor is the carrier material (P) consisting of 9 level and the second factor is the contact time (W) consisting of 9 level. Parameters measured were BOD, COD, TSS, and ammonia. The results showed that bioremediation by a consortium of bacteria Bacillus coagulans, B. licheniformis, B. subtilis, and Pseudomonas sp. the carrier material alginate-starch with a concentration of 1% at the time bioremediation 14 days can reduce levels of BOD by 81.49%, 81.44% COD, TSS 75%, and 35.82% ammonia by bacteria populations reach 2,89×1013 CFU/ml. The results also show that the encapsulation can maintain the viability of bacteria and is able to improve the bioremediation of organic matter compared to treatment without encapsulation.
