Analysis of Coastline Changes Using Satellite Image Data at Tanjung Bunga Makassar, South Sulawesi
Abstrak
One city that has been known as a tourism destination is Makassar, particularly Tanjung Bunga
beach. It is known to have various supporting facilities. The purpose of this research is to analyze coastline
changes using satellite image data and the cause of its changes. It was conducted from August to October 2012
in Tanjung Bunga using Landsat 5 and 7 satellite data analysed by ER Mapper 7.0 and ArcMap 10 softwares
to provide spatial and quantitative information on the coastline changes. Based on digital image processing,
results indicated that the coastlines of Tanjung Bunga changes from year to year particularly from erosion and
sedimentation. However, it was mapped and recorded that there has been some reclamation projects along the
beaches. The largest areal extent changes occurred in 2008 to 2010 amounting to 29,300 m2 involving 1,907 m
strip of coastlines being reclaimed. This study implies that there must be some control in the beach reclaimation
and other development projects to conserve and manage Tanjung Bunga for recreational purposes and other
intangible benefits.
