【 摘 要 】

The coastline is a dynamic land form because of the processes which come from the sea as well as from the land. Change in the coastline is the shifting position of the beach from its former place. There are many types of changes in the coastlines that are caused by many factors whether they are natural or human factors. The problem in this study is how coastline changes are caused by natural factors and human factors in Serang City. The research used Landsat 5, 7, and 8 images with 3 periods which were 1990 and 1998, 1998 and 2008, and the last period was 2008 and 2018. Abrasion and accretion is calculated based on the area, rate, distance changes, and long coastline experienced both. Land physical variables that are used in this research are topography, geology, land use and coastline, while the oceanic physical variables are ocean waves, currents, and tides. Human activities also become research variables such as sea sand mining. The result showed that coastline change happened along the coastal areas in Serang City. One of the evidence is an abrasion area that destroyed a mangrove forest in Karangantu Beach.
