SUMMARY
This research was conducted in June-November 2023 at Takisung beach, Tanah Laut Regency, South Kalimantan Province, aiming to determine the vulnerability index of Takisung Beach by using the high-resolution Coastal Vulnerability Index (CVI) method, with coastal geomorphological parameters, slope, relatively average increase - mean sea level, shoreline advance and retreat, maximum tides and significant wave heights. The CVI value calculated for each coastal vulnerability parameter is classified into five categories: very low, low, medium, high and very high. Based on the overlay results, it shows that the vulnerability index of the coastal area of Takisung is in the high category along 3.3 km (29.63%), the medium category is 2.3 (12.16%), the low category is 1.4 km long (57.07 %) and very low only 2 km (1.14%).
