摘要：South Sumatra is one of the largest petroleum producing provinces in Indonesia,especially in the region of Musi Banyuasin Petroleum resources other than legally cultivated by Pertamina as government representatives,but on the other hand the community also participate through Illegal Drilling activities. This study aims to determine the hydrocarbon content and characterization of petroleum produced illegally by communities in the Sangadesa,Babattoman and Keluang districts through the biomarker analysis of the distribution of n-Alkane C10-C34 (m/z: 57),pristane,phytane,sterane C27-C29 (m/z: 217,218,259) and specific biomarker using Gas Chromatography Mass Spectroscopy agilent GCMSD 6890/5973i with data analysis using MSD Chemstation F.01.01.2317 and Library Database NIST14. Petroleum samples taken from 10 illegal wells with a depth range of 80-250 meters and production period of 3 months until 3 years. Oil is produced through The illegal drilling is not the main oil source rock but the result of migration. Biomarkers Hydrocarbon analysis is one of the most widely used devices for exploration geochemistry,exploitation,production and forensic environment in the assessment and determination of sources of pollution related to petroleum material and derivatives very well..
