Fipronil is one of organochlorine pesticide with persistent nature in the environment. Fipronil can be biologically removed by utilizing bioremediation that utilizes microorganism activity. This research was conducted to remove fipronil in Stone Mineral Salt Solution (SMSs) liquid media by using Pseudomonas aeruginosa and Brevibacterium sp. with temperature and fipronil concentration as independent variable. Fipronil removal was conducted with temperature variations of 25, 30 and 35°C and fipronil concentration of 30, 40 and 50 mg/L. Based on the conducted Gas Chromatography-Mass Spectrometry (GC-MS) test, an optimal fipronil removal was achieved on 30°C temperature for three days with fipronil concentration of 40 mg/L. This finding shows that Pseudomonas aeruginosa and Brevibacterium sp. are able to remove fipronil with 65% efficiency, so that this research can be carried further to acknowledge physical parameter that influence fipronil removal in liquid media.
