Bioremediation is one method of treating hazardous waste environmentally friendly. This method of waste treatment Utilizes a microbial activity to treat hazardous waste. Oil sludge from the processing of petroleum in PPSDM Migas Cepu is one of the dangerous wastes, so it must be processed first before being discharged into the environment. The bioremediation process of oxygen and nutrients is needed by microbes to decompose harmful compounds in the oil sludge so that the addition of a bulking agent in the form of rice husk and sawdust is needed. Bacteria that help the bioremediation process are heterophilic bacteria, heterophilic bacteria used in this study are aeruginous Pseudomonas, Bacillus cereus and Bacillus spheres. This study aims to determine the effect of the addition of bulking agents on bioremediation and Determine the performance of heterophilic petroleum degrading bacteria in waste. The results of this study indicate the addition of a bulking agent Gives a fairly good result in bioremediation in the reduction in TPH and TCLP values Compared to bioremediation reactors without the addition of a bulking agent. Petrophilic Also bacteria play an important role in the bioremediation process as evidenced in the decline in TPH and TCLP values. The addition of a bulking agent, in a variable one (25; 75) there was a decrease in the value of% TPH namely 56.22%, variable 2 (40:60) there was a decline in the value of% TPH 55.95 and in variable 3 there was a decrease in the value of% TPH by 49, 73%. During the bioremediation process, the increase is in the pH value from 3. 6 to 6.5 indicates the presence of bacterial activity in degrading oil sludge waste. Percent of Percent Nitrogen and Carbon in bioremediation Decreased by 80 and 56%. The success of the bioremediation process was demonstrated by the results of FT-IR analysis, with peaks of 3418.39 cm-1, 2924.65 cm-1, and 1746.22 cm-1. © Published under licence by IOP Publishing Ltd.
