Indonesia has 16.100 islands and 92 is outermost islands. These small islands are currently experiencing the impact of climate change from sea level rise and global warming. This study aims to determine vulnerability of small island through changes in coastline and dynamic change of area due to climate change especially from coastline changes. Nineteen islands selected as representation of Indonesia seas regions. The data were collected from satellite images range from 2000 to 2020. To analyze, this research method uses Coastsat method to detect coastlines and QGIS to process coastline data and change of the island areas. The results of this study indicate that the average reduction in the area of small islands in Indonesia reaches 5.084% for approximately 20 years.
