Abstract: The coast line is the boundary line between land and seawater, where the position is not fixed and may change according to the tide and coastal erosion that occur. Changes in coastlines are caused by natural factors including ocean waves, currents, winds, river sedimentation, the condition of coastal vegetation as well as volcanic and tectonic activity and human factors, including the construction of ports and facilities, mining, dredging, destruction of coastal vegetation, aquaculture, protection beach and beach reclamation. Based on the description above, this research was conducted to find out the factors that influenced the changes in the coastline in TanjungBunga and the changes that occurred. From the results of tides, bathymetry and topography, the analysis showed that the change in the coastline of Tanjung Bunga was caused by sediment supply from the Jeneberang River and also by the construction of the Jetty beach building at the mouth of the Jeneberang River and groin which were not built effectively. At station 0 + 100 to 0 + 400 observation points, there was a setback in 2005 and 2009. While in 2007, station 0 + 100 to 0 + 300 progressed and in 2011, station 0 + 00 to 0 + 200 experienced progress. For station 0 + 500 to 0 + 800 it has progressed from 2003 to 2011.
