Abstract

Tidal flooding is a natural occurrence where sea water enters the land area when the sea level experiences a high tide which has the potential to cause property losses and even casualties. Demak Regency is one of the coastal areas located in the north of Java Island that has the potential to be affected by tidal flooding. Every year there is almost always tidal flooding with a height that varies from 10 cm to 200 cm. Located directly adjacent to the capital city of Central Java Province, Demak Regency is one of the densely populated districts, with a population density of 1291.83 people / km2. Therefore, it is necessary to study the social risks of tidal flooding in this area to minimize losses resulting from this disaster. This study aims to analyze the spatial distribution and hazards of tidal flood areas based on sea tide height scenario modeling, to analyze social vulnerability to tidal flooding, and to analyze the social risk distribution of tidal flooding based on modeling results and the level of social vulnerability in the Coastal Demak Regency. . This research uses quantitative methods accompanied by field surveys with the simple random sampling technique. Data processing is divided into several stages, including merging, reprojecting, and cropping DEMNAS data, rasterizing and assigning values to shoreline data, carrying out the modeling process with iteration techniques to produce tidal flood maps, determining the level of danger with several criteria, scoring and weighting social vulnerability, as well as determining social risk using a matrix. The results of the analysis show that the spatial distribution of tidal flood inundation results from the 200 cm scenario modeling has a total area of 127.32 km2 which inundated 40 villages from 4 sub-districts with 29 villages having a high level of danger, 6 villages having moderate danger, and 5 villages having low danger. A total of 20 villages has low social vulnerability, 14 villages with moderate social vulnerability, and 6 villages with high social vulnerability. Then the results of the social risk level classification show 5 villages have low social risk, 20 villages have medium social risk, and 15 villages have high social risk.
