Sedimentation in the coastal waters was influenced by oceanographic factors and the rivers which flowing to the waters, so the source of the sediment can be from the sea or the rivers. The sediment source can be identified by observation of the sediment texture and mineralogy. Result of research indicate that the grain size of sediment was dominated by silty sand. The petrography analysis indicate that all of sediment contain volcanic glass which size and content increased to the river. On the other hand, carbonate content in the sediment was about 1,514 - 19,225% which distributed and increase to the onshore. Based on the data can be concluded that the volcanic source was from onland and the carbonat was from the sea.
