Study on utilization of leachate as inoculum of microorganism in bioremediation of oil sludge on Total Petroleum Hydrocarbon (TPH), C/N ratio, Polycyclic Aromatic Hydrocarbon (PAH) and heavy metals content was conducted during 45 days. The aim of the present work was to assess the ability of leachate inoculum in degrading oil sludge. The main parameters in this study, TPH and C/N ratio were analyzed within 15 days of interval while PAH and heavy metals were measured at the beginning of experiment (day 0) and at the end of experiment (day 45). Supporting parameters such as pH, temperature and humidity of medium were also analyzed. Our finding showed that the leachate inoculum reduced TPH and Cr content as much as 24.20% and 5.88%, respectively. On the other hand, C/N ratio in the oil sludge medium 30% increased as much as 1.14%. The PAH compounds that can be degraded by leachate and were not redetected at day 45 are 9-Octadecenoic acid, methyl ester (C₁₉H₃₆O₂) and Hexacosane (C₂₆H₅₄). These results led us to conclusion that the leachate could be alternatively used in optimization of oil sludge bioremediation.
