Determine of Potential Evacuation Locations as Disaster Mitigation Against Landslides

Bandar Lampung City has a lowland topography, which is quite diverse in valleys to ridge hills. The city’s development made the face of the city of Bandar Lampung turn into a dense residential area between the hills. Landslide is one of the disasters that often occur in Indonesia.

Description
Summary:Bandar Lampung City has a lowland topography, which is quite diverse in valleys to ridge hills. The city’s development made the face of the city of Bandar Lampung turn into a dense residential area between the hills. Landslide is one of the disasters that often occur in Indonesia. About 15 sub-districts that are prone to landslides in Bandar Lampung, including West Telukbetung, East Telukbetung, South Telukbetung, Bumiwaras, Panjang, Kedamaian, North Telukbetung, Tanjung Karang Pusat, Enggal, Tanjung Karang Barat, Kemiling, Langkapura, Kedaton, Rajabasa and Sukabumi (BPBD, 2018). Research about landslide-prone areas with a geospatial approach aimed at disaster mitigation efforts. The study results will be necessary information about disaster mitigation to minimize loss of life and material. The geospatial approach integrates landslide threat maps with road networks and public facilities. Also, the landslide threat area’s accessibility and affordability functions can be arranged to secure the city’s priority location. The preparation of a landslide threat map begins by compiling an entire dataset in spatial data information from various sources. Whole datasets are arranged based on parameters that affect landslides. Each parameter has a different weight and is summarized in the Overlay method. It is hoped that this research can be used as a reference in disaster management and spatial planning in Bandar Lampung in the future. The determination of public facility services using the Analytical Hierarchy Process (AHP) method.
