Changes in Coastline with Landsat Imagery Approach and Its Impact on the Pattern of Development of Coastal Settlement Areas (Case of Indramayu Regency)

Abstract

This research is entitled Changes in Coastline with Landsat Imagery Approach and Its Impact on the
Pattern of Development of Coastal Settlement Areas (Case of Indramayu Regency). Problems Changes
in the coastline in the coastal residential area of Indramayu Regency have an average abrasion rate of
23.64 Ha/year and an average accretion rate (sedimentation) of 4.81 Ha/year, making it difficult to
develop the area for residential areas. This condition results in frequent changes in the area and policies
on the development of coastal settlement areas in Indramayu Regency. The changes in the coastline can
be seen spatially by using images such as Landsat images. Analysis method used is; land capability unit
analysis (land capability), analyst is land physic, accessibility analysis, environmental infrastructure
analysis, and GAP analysis (Gap Analysis). Changes in the coastline in Indramayu Regency, researchers
used time series image data, namely by using Landsat imagery in 2000, 2005, 2010, 2015 and 2020. The
largest shoreline changes occurred in 2020, namely with abrasion of 950.71 Ha and Accretion of
1,329.41 Ha; The results of the SKL analysis show that the land capability at the research location is
obtained which has the widest proportion of the classification of development of low development
capability, which is 55,277.00 Ha; The results of the analysis of land suitability for coastal settlements
in Indramayu Regency, obtained a very suitable land area of 8.35% or an area of 5.591.24, while the one
with the largest designation area is at the level of suitability according to which is 30,867.46 Ha or about
46.09 %; Suitability The designation of coastal settlements is carried out by comparing the results of the
analysis of land suitability for coastal settlements with the spatial pattern plan of the RTRW of
Indramayu Regency which exists. For the suitability of the designation of coastal settlements that are
NOT COMPATIBLE, it has an area of 29,298.94 Ha or about 43.75%. As for the suitability of the
settlement designation that is NOT COMPATIBLE based on the results of the study covering an area of
1,215.40 Ha or about 1.8%.
