  • Research has been carried out on the effect of salinity of NaCl, pH, and temperature on petroleum recovery with variations in the levels of 0%, 1.5%, 3%, 4.5%, and 6% NaCl, variations in pH 5, 6, 7, 8 and 9 and temperature variations of 40°C, 50°C, 60°C, 70°C, 80°C, and 90°C using Burkholderia glumae bacterial culture. Measurement of % TPH (Total Petroleum Hydrocarbon) was carried out by maceration method with initial TPH of 40.33%, followed by measuring the final TPH. The optimum conditions were obtained at 3% NaCl salts, pH 5 and 70°C temperatures with the results of% recovery of 32.31%. The best recovery results for each variation were carried out by GC (gas chromatography) analysis to determine the abundance of hydrocarbon components which were decomposed due to degradation of the culture of Burkholderia glumae bacteria. Based on the measurement of histogram, it was found that the NaCl 3% salts of long chain hydrocarbons decomposed into chains <C10, C11–C14, C18–C21, and >C22. At pH 5 long chain hydrocarbon compounds which break down into chains <C10, C11–C14, C18–C21, and >C22, and temperature 70 ° C long chain hydrocarbon compounds which break down into chains <C10, C18–C21, and >C22. Statistical test results using ANOVA obtained Fcount > Ftable, thus indicating a significant difference from each variation.
