Abstract

Global climate change has caused significant sea level rise, primarily due to melting polar ice caps and thermal expansion of seawater. Makassar City, particularly Ujung Tanah District, which has a coastal area, is highly vulnerable to the impacts of this sea level rise. This study aims to analyze the level of disaster vulnerability due to sea level rise in five coastal villages in Ujung Tanah District using ArcGIS-based spatial analysis methods. The parameters analyzed include slope gradient, land use, wave height, current speed, wind speed, and tides, then classified into three levels of vulnerability: low, medium, and high. The results show that most coastal areas (around 53%) are categorized as high vulnerability, while the other 44% are categorized as medium vulnerability. This vulnerability is caused by a combination of geographic factors and ocean dynamics that influence coastal conditions. This study recommends increasing community participation in coastal environmental conservation and integrated disaster mitigation planning to reduce the risk of sea level rise in Ujung Tanah District
