. The objective of this research was to obtain potential bacteria capable to degrade heavy oil and used oil. The research carried out in several steps: isolating bacteria from ten sampling location, selection of bacteria capability to degrade heavy oil and used oil in liquid minimal media, characterizing the physiology and biochemistry of bacteria, testing of Total Petroleum Hydrocarbon (TPH). Five selected isolates was obtained, they were: OB3-10% from Babakan Lebak river sediment, OB5-10% and MB5-5% from dried cow manure, OB9-10% from taro rhisozphere, and MB10-10% from oil palm plantation area. Isolate MB5-5% had the best capability in reducing TPH of heavy oil contaminated soil and isolate OB9-10% had the best capability in reducing TPH of used oil contaminated soil.
