Contamination of petroleum waste has endangered the environment, yet its processing technology is not effective and efficient. It is becaused that by petroleum waste is difficult to be degraded by bacteria due to many complex bonding compounds containned in this oil waste. Therefore, this study used ozonation as pretreatment process with the aim to enhance the biodegradation process. The variations in operating conditions performed in this study are dose of ozone and pH. The bacteria used as a degrading agent is the Pseudomonas Aeruginosa. The results show thatozonation process can the enhance biodegradability as indicated by the increase of degradation and population growths of bacteria. In addition, the ability of the bacteria P. aeruginosa in degrading petroleum waste is varied with ozone doses adn pH values. The highest percentage of degradation achieved at dose of of 0.53 g ozone/h and pH 7.48 are approx from 56.52% without ozone pretreatment to 79.32% after 7 days incubation.
