Abstract
Energy is a basic human need which continues to increase every year. The fact is that the production of energy such as petroleum in Indonesia has decreased due to the depletion of petroleum reserves. The increasing consumption and increasing demand for energy has prompted the government to implement renewable energy planning. The solution that can be offered is Enhanced Oil Recovery (EOR) technology. Meanwhile, one of the developments in EOR technology that is environmentally friendly and able to increase oil recovery well is Microbial Enhanced Oil Recovery (MEOR). In the MEOR system, a bioproduct injection component called biosurfactant is used. The performance of biosurfactants in the system can be done by reducing the interface stress and mobilizing oil in the rock. The production of biosurfactants can be increased with the help of secretion of microorganisms. Based on the literature obtained, Bacillus licheniformis is a type of native bacteria that has the potential to produce biosurfactants with lipopeptide characteristics. Bacillus licheniformis is able to produce several extracellular enzymes, namely amylase, amino, peptidase, metal protease, lactamase, endo-N-acetyl glucosaminide and lipase. In addition, several studies have shown that Bacillus licheniformis has the potential to be applied to MEOR, bioremediation and industrial biotechnology. However, the biosurfactant produced from the bacterium Bacillus licheniformis requires a substrate to increase oil recovery. One type of organic substrate that can be used is tofu liquid waste. Tofu liquid waste contains high organic and nutrient materials consisting of 90.72% water, 1.8% protein, 1.2% fat, 7.36% crude fiber, and 0.32% ash. The author sees the potential use of tofu liquid waste because of its environmentally friendly nature. Therefore, the author offers an idea entitled The Potential Application of Bacillus Licheniformis Biosurfactant and Tofu Liquid Waste as an Application of MEOR Technology.
