Analisis Perubahan Garis Pantai Pesisir Muara Sungai Rokan Menggunakan Citra Satelit Dan Google Earth Engine (Gee)

ABSTRACT


The coastal area of the Rokan River estuary is where the Rokan River flows into the Malacca Strait. The shoreline in this region undergoes dynamic changes due to the high hydrodynamic properties and sediment transport in the downstream section of the river. This study aims to detect and analyze the spatial changes in the shoreline at the Rokan River estuary, Riau Province, Indonesia, using satellite imagery and GoogleEarth Engine (GEE). This approach is highlyeffectiveas it saves time, cost, and labor. The method used is a quantitative descriptive analysis based on the digitization of Landsat imagery and GEE. Overall, the study found that the rate of erosion at the Rokan River estuary is relatively low, while the rate of accretion is very high. The largest erosion event occurred between 2004 and 2006, affecting an area of 541.56 Ha, while the most significant accretion happened between 1996 and 1998, covering 2,660.10 Ha. From 1990 to 2024, the total erosion area was 4,566.56 Ha with an erosion rate of 134.31 Ha/year, and the accretion area was 16,610.94 Ha with an accretion rate of 488.56 Ha/year. High sedimentation rates were observed in Parit Aman and Serusa villages, with accretion rates of 72.53 Ha/year and 66.43 Ha/year, respectively. Islands with high accretion rates include Halang Island, Serusai Island, and Barkey Island, with rates of 9.45 Ha/year, 12.94 Ha/year, and 128.10 Ha/year, respectively, along with Pedamaran Island in the upstream area with an accretion rate of 25.17 Ha/year.
