Coastline Changes On The Coast of Cirebon Using Landsat

Abstract

The coastal region is a very dynamic region because it undergoes two processes, natural and non-natural. The coastline can change due to waves, tides and human activities. Human activities are mostly carried out in coastal areas including reclamation for ports. Coastal area of Cirebon is one of the areas that experiences land addition or port reclamation which causes changes in the coastline. Images interpretation is one way to find out changes that occur in coastal areas by using Landsat 8 OLI and Landsat 5TM imagery. The image extraction method using RGB 432 can see the differences between the sea-land and how the changes has occurred in the last ten years, by overlaying both of them which results in extensive abrasion and accretion that occurs on the coast of Cirebon. The abrasion area is 107.12 Ha and the accretion is 941.17 Ha.
