Abstract
Research on the vulnerability study of the coastal area of Dumai City, Riau Province. The purpose of this study was to determine the assessment and category of vulnerability levels, as well as to calculate the parameters that affect coastal vulnerability. The method used a survey method with direct observation, while the analytical method used CVI calculation, the root of the multiplication of each variable weight. The data required includes primary data with direct observations, and secondary data with data from remote sensing satellites, primary data including coastal geomorphology, land use, tides, and secondary data including DEM (Digital Elevation mode), coastal slope, changes coastline, relative water level rise, significant wave height. The results of this study at the observation location obtained 3 categories of vulnerability, namely low, high, and very high vulnerability levels found on the coast of Dumai. The category of vulnerability in the low class is located in the Dumai Barat sub-district in Purnama village with a value of 4,33-5,00, the vulnerability category in the high class is located in the Dumai Timur sub-district in the Purnama village grid A2 and A4 on the Tanjung Palas grid A12-A14 with a value 8,66-10,61, and the category of vulnerability in the very high class is located in the District of Dumai Barat grid A5–A8, District Dumai Kota grid A9–A10, and District Dumai Timur sub-district in Tanjung Palas grid A15 with a value of 12,99-20,00.
