Bioremediation using Pseudomonas aeruginosa and Biostimulant Organic Waste (BOW) could potentially be a method of reducing hydrocarbon levels in contaminated soil. Pseudomonas aeruginosa struck in Nutrient Broth is applied directly to contaminated soil, while BOW produced from fruit waste is used as a source of nutrition for Pseudomonas aeruginosa with yield variations of 0\%, 15\%, 30\%, and 50\%. The bioremediation process lasts for 40 days. Every 10 days a growth measurement of Pseudomonas aeruginosa, total microbes, and Total Petroleum Hydrocarbon levels is performed. (TPH). The results of the research show that the BOW content has not yet met the quality standard with only N 0.54\%; P 0.58\%; K 0.37\%. Nevertheless, the addition of BOW can still be used as a microbial nutrient to accelerate the growth process. Pseudomonas aeruginosa and total microbes at the end of the bioremediation (day 40) was found at the administration of 50\% BOW, which is 2,02 x 108 CFU/mL and 2,45 x 1012 CFU /mL. These results are supported by environmental conditions, namely the temperature range 29-31 oC, the water level 12-55\% and the pH 6,8-7,1 so it can lower the level of TPH to 0.6\%.} }
