Field Test of "U-Champ" Biosurfactant in Oil Spill Bioremediation

One of the serious environmental problems of the oil and gas industry is handling oil spills. Oil spills can be managed by using bioremediation in the form of biosurfactants. In this research, biosurfactants called U-Champ were used which can impact in remediation of oil spills. The research conducted was testing the effectiveness of biosurfactants on Cepu Field contaminated soil in reducing TPH and heavy metals. The method is done by stirring the contaminated soil with various concentrations of biosurfactant product in an artificial tank. Based on the test results, a decline in TPH and TCLP along with the increase in U-Champ biosurfactant concentration was used. The addition of 6 Liters of biosurfactant gave the most significant reduction. Some of the heavy metals in the soil decrease, but some also have increased. As an example, it can be seen in Ba metal, the addition of U-Champ biosurfactant as much as 1.5 L (0.3% v / v) resulted in a decrease in TCLP of 11.085%. The qualitative result is evidenced by the growth of various plants in each artificial tank.
