10th Joint Conference on Chemistry, Solo, INDONESIA, SEP 08-09, 2015International audienceSedimentary aliphatic hydrocarbons content have been studied quantitatively and qualitatively using GC/MS method in eight coastal stations located in the Jakarta Bay, North of Jakarta, Indonesia. The total concentrations n-alkanes have ranged from 480 mu g.kg(-1) to 1,935 mu g.kg(-1) sediment dry weight. Several ratios (e.g. CPI24-32, NAR, TAR, Pr/Phy, n-C-17/Pr, n-C-18/Phyt, n-C-29/n-C-17, Sigma n-alkanes/n-C16LMW/HMW, Paq and TMD) were used to evaluate the possible sources of terrestrial-marine inputs of these hydrocarbons in the sediments. The various origins of aliphatic hydrocarbons were generally biogenic, including both terrigenous and marine, with an anthropogenic pyrolytic contribution (petrogenic and biogenic combustion). Two stations (G,H) were thehighest concentration and had potential risk to environmen
