This study conducts an analysis related to distribution and source of PAH in sediment around Makassar coast. Sediment sample has been taken up using Van Veen grab and put in a plastic sac, brought to laboratory, added with salt, stored in dried freezer, and followed for PAH analysis. Sample preparation has been carried out using DCM and n-hexane (1:1) solvent to obtain extract of organic matter (EOM). The EOM is fractionated to yield alkane fraction (F 1 ) and aromatic fraction (F 2 ) containing PAH. The GC-FID has been used to determine PAH concentration through analysis of F 2 . Validation of the analytical method applies linearity, LoD, and LoQ. The recovery test has fulfilled for all PAH compounds except for naphthalene and fluoranthene . The highest concentration of PAHs is found at station 7 with benzo(a)antracene 933.23±3.88 ppm and perylene 205.75±19.45 ppm. The lowest total concentration of PAHs is found at station 12 located at the estuary of Tello River caused by dilution from both river and sea water. The source of PAHs in sediment is generally from petrogenic and pirolytic process.
