Abstract

This study aims to analyze the rate of change in the shoreline and find out the back and forth of the coast in a certain period. Coastal areas play an important role in economic development, namely the transport and tourism industries. Unfortunately, the spatio-temporal variation of the shoreline is very dynamic and is of great concern due to the threat of erosion and accretion. This erosion mechanism is not only the result of natural processes (for example, wind, waves, currents and tides) but also human activity. In this study, the shoreline was considered the boundary between the continent and the sea. Due to the frequency of extreme events such as storm surges, floods, etc. especially in coastal areas in the past decades, scientists are increasingly interested in the study of shoreline dynamics. Satellite imagery used to interpret shoreline changes are Landsat 7 / Enhanced Thematic Mapper (ETM) imagery data path 112 row 59 dated September 11, 2001, Landsat 8 Operational Land Imager (OLI) imagery data path 112 row 59 dated October 22, 2013, and Landsat 8 Operational Land Imager (OLI) imagery data path 112 row 59 dated January 27, 2020, with a spatial resolution of 30 m. Analysis of changes in area was carried out intercropping between land and waters from all years. This method is carried out to find out the extent of the difference in the littoral regions of abrasion and accretion. This study used statistical data, namely NSM, EPR, and LRR with a distance along the shoreline of 10-m and a transect distance from the baseline of 30 m. The rate of abrasion and erosion in Totok Bay has a significant impact on the activities of its coastal communities, therefore handling protection of the shoreline needs to be carried out, such as by making sea walls or planting mangrove trees along the coast of Totok Bay.
