Abstract

Landslide, one of the natural disasters that often occur, especially in areas that have moderate to high slopes. Imogiri is a sub-district located in Bantul Regency. This sub-district has a percentage of relief of flat to wavy by 30% and relief of wavy to hilly by 70% with a predominantly clay texture. Therefore, Imogiri is included in an area that prones to landslides. In a history of disaster BPBD Bantul explained that there are several areas in Imogiri Subdistrict such as Village of Wukirsari, Sriharjo, Selopamioro, and Karangtengah which are in the red zone. According to the BPBD, in Bantul there were more than 2.000 people living in the red zone. Based on this statement, this study aims to analyze the areas in Imogiri Subdistrict which have low to high landslide hazard levels, as well as analyze the level of social and economic vulnerability of the people living in Imogiri Subdistrict, especially areas with potential landslides. The results obtained from this study in the form of landslide vulnerability maps, social vulnerability maps, and economic vulnerability maps. Based on the map, it can be analyzed that the Imogiri has a moderate level of landslide vulnerability, while the level of social and economic vulnerability in some areas shows a high level of vulnerability. This is influenced by population density, type of work, and its relationship with the level of landslide vulnerability in the areas.

Abstract

Selo district is an area prone to landslides proven to be 32 events in a period of 10 years however, has a population of 29,342 people. The population is spread on moderate landslide vulnerability to very high landslide vulnerability. The purpose of this study was to determine the distribution of landslide vulnerability in the District of Selo and determine the vulnerability of the population to landslides in the District of Selo. Research using descriptive survey methods utilizing numerical data processed through ArcGIS with scoring and overlay processing. Selo District is dominated by moderate population vulnerability to high landslides.

Abstract

Depok City is a satellite city with a strategic location, thus triggering urbanization. Urbanization is one of the causes of the increase in population, in 2011 the population of Depok City reached 1,813,612 people, in 2021 it would become 2,056,335 people. The increase in population and limited urban land resulted in the conversion of non-built land use into built-up land. Built-up land absorbs and reflects heat, so the surface temperature is high. The development of built-up land can result in an increase in surface temperature and trigger the Urban Heat Island (UHI) phenomenon. This study aims to identify the distribution of land cover and surface temperature, analyze the ef ect of built-up land cover development on the increase in surface temperature, and analyze the relationship between the increase in surface temperature and the distribution of UHI in Depok City in 2011 and 2021. Landsat image data processing methods are used to obtain classifications. land cover using the Maximum Likelihood algorithm, a survey was conducted to validate the results, then the classification of surface temperature was obtained using the Mono-Window Brightness Temperature algorithm. UHI identification is obtained by using the threshold value equation. The ef ect of built-up land cover development on the increase in surface temperature was tested using simple linear regression. The results showed the development of the distribution of built-up land cover, in 2011 it had an area of 116.98 Km2 to 150.87 Km2 in 2021. The distribution of surface temperatures in Depok City in 2011 was dominated by class II surface temperatures with an area of 132.29 Km2, while in 2021 dominated by surface temperature class IV with an area of 126.03 Km2. The development of built-up land cover has an influence on the increase in surface temperature by 40.5%. The increase in surface temperature is directly proportional to the increase in the UHI threshold value, the distribution of UHI in Depok City in 2011 has an area of 52.09 Km2 to 65.63 Km2 2 in 2021.
