| dc.description.abstract | The observation location in this study was Dolat Rayat District, Karo Regency. Dolat
Rayat District is one of the Districts in Karo Regency that has a fairly high frequency of
landslides, namely 5 incidents in the last 5 years from 2019-2024. The purpose of this
study was to map landslide-prone areas in Dolat Rayat District, and analyze evacuation
points in residential areas prone to landslides. The stages in this study began with
literature studies and field surveys, secondary data collection, then data processing using
ArcGIS and finally primary data collection in the form of evacuation points and routes
for landslide-prone settlements. Based on the results of the overlay and scoring, it was
obtained that the landslide vulnerability was moderate and high with an area of 1,625 Ha
(71.1%) and 375 Ha (16.4%) respectively. While for the very high category it has an area
of 4 Ha (0.2%) and for the low category it is very minimal, namely 281 Ha (12.3%).
Based on the mapping and analysis, it was found that there are 3 (three) villages in Dolat
Rayat District whose settlements are located near high landslide-prone areas, namely
Dolat Rayat Village, Sugihen Village, and Bukit Village. Based on the mapping and
analysis, evacuation points and routes were then determined. Evacuation points were
determined in open areas with relatively low vulnerability, and evacuation routes were
determined based on the closest distance and road conditions from landslide-prone
settlements to evacuation points. | en_US |
