The purpose of this research is to obtained the best interaction between bacteria and compost in the process of hydrocarbon bioremediation in soil-contamination lubricant oil. Alcaligenes sp. and Bacillus sp. from our previous study is applied in this study.We used 3%, 6% and 9% household waste compost as the biostimulant sources. Biodegradation process is indicated by total petroleum hydrocarbon (TPH) value and the quality of bioremediated soil is checked by pH value. TPH and pH value is measured in days of 15th and 30rd. This study showsthat interaction of Alcaligenes sp and Bacillus sp consortium and 6% household waste compost gave the best TPH value (27.62%) in biodegradation process after 15 days. However, on days of 30rd, the best result is shown by the interaction of Alcaligenes sp and 9% household waste compose. The TPH value after 30 days of incubation is 30.54%. The soil's pH is decrease from 7.98 to 5.79 respectively. It is concluded that interaction of Alcaligenes sp and household waste compost can increase degradation rate of hydrocarbon in soil-contaminated lubricant oil. © 2019 IOP Publishing Ltd.
