Rapid rebuilding of tsunami affected areas carried out by the government and the community in the last decade has completed gradually, but the impact along the coastline towards the mainland of Aceh Jaya Regency is occurring. To obtain accurate data against this change, multi-temporal data is needed in order to present information about the changes occurred from the past to current state. This research aims to observe the changes of land use and cover change in coastal geomorphology by utilizing multi-temporal remote sensing data. This research uses qualitative descriptive method based on multi-temporal satellite imagery interpretation results for 2004, 2009 and 2017 respectively. Supervised classification with maximum likelihood analysis standard was carried out. Geomorphology change of the shoreline was designated by interpretation and overlay temporal satellite image data. Results show that types of land cover have changed, primarily to vegetation, open land, water body with vary in the total area follow the year of observation. Abrasion and accretion has occurred on the site of research reached the area of 457.90 hectares and an area of 5.78 hectares. In term of coastal geomorphology, some area of the location has changed with vary in length and width. Key words: land cover, coastal geomorphology, multi-temporal, Aceh Jaya .
