Simulasi Proses Bioremediasi Pada Lahan Terkontaminasi Total Petroleum Hidrokarbon (Tph) Menggunakan Serabut Buah Bintaro Dan Sekam Padi (The Simulation Of Bioremediation Process On Total Petroleum Hydrocarbons (Tph)-Contaminated Land Using Bintaro Fibers And Rice Husk)

Abstract

Bioremediation is a recovery process for the contaminated land by utilizing the activities of microorganisms. Various technologies have been developed to obtain the optimal result, one of them is utilizing bulking agent as additive to increase the soil porosity and the contaminant biodegradation rate. The purpose of this study to examine the best effectiveness of Total Petroleum Hydrocarbons (TPH) removal between utilization of bintaro fibers and rice husk bulking agent in remediation process. The exogenous microorganisms that used on this study were Bacillus sp. The contaminated land was made by putting about 10% of lubricating oil, 1% of the bacteria Bacillus sp, 1% of bulking agent; 0.5-0.8% of NPK fertilizer, and 1% of urea fertilizer. The reactor that used on this study was landfarming type, which is the simple reactor. The humidity on this reactor maintained by added some water for twice a week. The efficiency of TPH concentrations for two months using bintaro fibers and rice husk were 49.5% and 56.12% respectively. Thus, the use of rice husk as bulking agent is more effective than bintaro fibers in biodegradation of bioremediation process.
