title = "Organic geochemistry characteristic of aliphatic hydrocarbon fraction of Sawahlunto coal, Ombilin Basin, West Sumatra",
abstract = "Sawahlunto coal from West Sumatra has been analyzed to determine the characteristics of organic geochemistry. Coal was extracted by Soxhlet method with a mixture of aceton: methanol: chloroform (47:23:30) as solvent. The extracts were fractioned using column chromatography. Aliphatic hydrocarbon fraction was analyzed using Gas Chromatography - Mass Spectrometry (GC-MS). The analysis of aliphatic hydrocarbon fraction shows the presence of n-alkanes and isoprenoids. The n-alkanes compounds are distributed from n-C16 to n-C31 with predominance of carbon long chains (>20). These compound were expected formed by higher plants terrestrial. The presence of pristane and phytane compounds with maximum abundance in pristane compounds exhibits a deposition environment of coal under oxic conditions. Two samples of Sawahlunto coal were classified as sub-bituminous coal based on the value of caloric analysis.",
