Abstract
The risk of environmentall pollution due to diesel fuel spills increases every year therefore it takes an effort that is safe for the environment with low production costs. These bacteria are grown in the media productions that are Tryptone Water, cornstarch wastewater and tapioca wastewater each of them had been given pH variation that are 6, 7, and 8 then incubated for 7 days. Biosurfactants from media productions were harvested by centrifuge and tested for biosurfactant activity with 3 test parameter there are drop collapse test, oil displacement test, and emulsification test. The result showed that the biosurfactants produced from the three types of media production were able to dissolve diesel fuel. Biosurfactant produced from cornstarch wastewater pH 7 showed the most optimum dissolving of diesel fuel with emulsification index is 63.88%
