UJI RECOVERY MINYAK BUMI MENGGUNAKAN BIOSURFAKTAN BAKTERI PSEUDOMONAS PELI TERHADAP VARIASI KADAR GARAM, PH, DAN TEMPERATUR
Daftar Isi:
- Oil recovery test had been done by using biosurfactant and bacterial cell culture from bacteria Pseudomonas peli with variation of NaCl, pH, and temperature to sludge which still contain crude oil. Test oil recovery obtained by determining % TPH (Total Petroleum Hidrocarbon). The samples were prepared from the soil contaminated 40,33% petroleum and after being treated with biosurfactant and cell culture from bacteria P. Peli with variation of NaCl salt, pH and temperature of succesive 27,667%, 28,867% and 26,733. The optimal producing of oil recovery at 6% NaCl concentration, pH 7 and 80 oC with the value oil recovery up to 33,713%. The result of statistical tests using ANOVA obtained F count > F table it proves that bacteria P. peli if varied salt concentration, pH and temperature will give significant difference to oil recovery. The results of GC (Gas Chromatography) qualitatively showed that biosurfactants and cell culture from bacteria P. Peli with 6% NaCl, pH 7 and temperature 80 oC could degrade, dissolved hydrocarbon compounds and forming new compounds. Keywords : Biosurfactant, Pseudomonas peli, Oil Recovery
