Abstrak. This study presents the result of sewage pollution monitoring in sediments collected from 13 rivers that run through Jakarta city in 2010 using linear alkyl benzenes (LABs) as molecular marker of sewage contamination. The surface sediments samples were extracted by pressure liquid extraction, purified by two-step silica gel column chromatography, and analyzed by gas chromatograph (GC)-mass spectrometer (MS). The result clearly revealed high total LABs concentrations (6171-1559373 ng/g-dry weight) in all sampling locations. I/E ratios (a ratio of internal to external isomers of LABs) ranged 0.9-1.3, were close to the I/E ratios in raw sewage. The high concentrations of LABs with low I/E ratios showed that the rivers in Jakarta are heavily affected by untreated sewage. This study highlights the urgently needed of water treatment system in Jakarta.
