Water pollution is one of the world’s main concerns today. Governments in various countries have tried to find solutions for reducing this problem. Indonesia has a great diversity of local microorganisms. Pichia kudriavzevii UMJ-L, Trichosporon asahii UMJ-A2, Burkholderia ambifaria UMJ-A1, Burkholderia stabilis UMJ-R, Gluconacetobacter saccharivorans UMJ-K, and Pseudomonas putida are local microorganisms that can be used for bioaugmentation in wastewater. The results of bioaugmentation of domestic and organic wastewater not only can be used for watering plants but also expected to have a positive value as fertilizer for the growth or production of some plants. Microorganisms in this study were the result of isolation, which is made of pellets from rice flour/bran. The pellet after mashed is used as an inoculant which acts as bioaugmentation of incubated wastewater for 4 days. The results showed that bioaugmentation fertilizer from domestic wastewater was better than other wastewater when used as fertilizer on plants. Better results, all wastewater still requires the addition of inorganic fertilizers between 25% to 50% because of the low nutrients content.
