Beach is one of the many important locations for the economy and livelihoods of local and surrounding residents. Peukan Bada Beach is directly facing the Indian Ocean so that it is directly affected by the Hydro-Oceanography process, which is influenced by waves, currents, tides, and erosion-sedimentation that affect changes in the coastline. The research location is Lamteungoh-Kuala Cangkoi beach. This study intends to analyze the dynamics of coastline changes and sediment rates along the coastline. The data collected is in the form of aerial imagery photos using drones and using DJI GO 4 and DroneDeploy software. The study data retrieval was carried out 4 times on 3/1, 18/1, 2/2, and 17/2 in 2022 at the lowest low tide on the new moon and full moon. Aerial imagery photos were analyzed using Agisoft Metashape software and produced Digital Elevation Model (DEM) and Orthophoto maps. The DEM map obtained was analyzed spatio-temporally using the Digital Shoreline Analysis System (DSAS) method in the Arcmap software so that the sedimentation rate was obtained around the coastline and obtained the largest accumulation of erosion-sedimentation area in 2/2/22-17/2/22 was 12,168,318 m2. The largest sedimentation in 2/2/22-17/2/22 was 8,720,076 m2, while the largest erosion in 18/1/22-2/2/22 was 7,004,299 m2.
