	<span style="line-height:1.5;">Petroleum contamination in the soil is known to
reach the location of groundwater resources thereby potentially contaminating
groundwater that is used as the primary source of clean water. Hydrocarbon
compounds contained in the petroleum are also compounds that are most difficult
to breakdown. One way of overcoming this
problem is by bioremediation, which is a recovery of environmental condition by
utilizing biological</span><span style="line-height:1.5;"> </span><span style="line-height:1.5;">microorganism activity to reduce levels of toxicity
of pollutant compounds. The research was conducted in laboratory scale for 30
days using biostimulation methods with NPK fertilizer as nutrient. Variations
are done in the level of NPK fertilizer nutrients to the contaminated soil
(control, 10%, and 20%). The parameters tested include the value of total
petroleum hydrocarbons (TPH), temperature, pH and total microbial colonies contained
in the contaminated soil samples. Results of research showed that the addition
of nutrients is as much as 20% (w/w). Bioremediation was able to reduce TPH up
to 4.23% (initially 8.37% TPH) in week 4 of the research. Addition of nutrition
in the form of NPK fertilizer highly affects the TPH value degradation rate in
oil-contaminated soil samples. Higher concentration of NPK fertilizer added
leads to better degradation rate of NPH value.</span>
