Abstract
Kemujan Island has ecosystem resources such as coral, mangrove and seagrass ecosystems. The western waters have a unique shape, because some of the waters are in a location that is covered by land and mangrove trees thrive. the existence of mangrove ecosystems and the shape of the waters that are semi-enclosed will affect the grain size distribution. The study of the distribution of sediments on Kemujan Island is aimed at obtaining an overview of the sediment conditions and their relationship to the hydrooceanographic process. The research area of closed waters and open waters is 30 stations. Sediment samples were taken using a vanveen grab. Sediment grain size analysis used dry sieving and wet sieving (pipepeting) methods. The results obtained show that the distribution of sediment patterns is more dominated by sand and the type of fine sediment is found in deeper waters ≥ 7 meters and the location of the station is far from the source (land). The distribution pattern of coarse sediment is associated with weaker currents and shallower waters.
