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.

Abstract

Perubahan penggunaan lahan yang terjadi di kecamatan Mojosongo,kabupaten Boyolali memiliki potensi untuk mempengaruhi potensigerakan tanah. Perlu dilakukan penelitian pengaruh perubahanpenggunaan lahan terhadap tingkat potensi gerakan tanah yang ada.Tujuan penelitian ini adalah (1) mengidentifikasi perubahanpenggunaan lahan, (2) mengidentifikasi perubahan tingkat potensigerakan tanah, dan (3) melakukan analisis terhadap pengaruhperubahan penggunaan lahan terhadap tingkat potensi gerakantanah di Kecamatan Mojosongo, Kabupaten Boyolali. Metode yangdigunakan dalam penelitian untuk mencapai tujuan adalah (1)melakukan analisis overlay terhadap peta penggunaan lahan tahun2006 dan tahun 2016, (2) melakukan analisis overlay terhadap petapotensi gerakan tanah tahun 2006 dan tahun 2016, dan (3)melakukan analisis pengaruh perubahan penggunaan lahan terhadaptingkat potensi gerakan tanah secara deskriptif kuantitatif dankualitatif. Hasil penelitian adalah: (1) peta perubahan penggunaanlahan, dengan perubahan penggunaan lahan paling besar adalah:kebun ke pemukiman sebesar 541,43ha atau 12,34%, (2) petaperubahan tingkat potensi gerakan tanah, dengan perubahan tingkatpotensi gerakan tanah terbesar adalah: dari rendah ke tinggi sebesar512,91ha atau 11,69%dan (3) Perubahan penggunaan lahan yangmengubah potensi gerakan tanah adalah: perubahan penggunaanlahan kebun ke pemukiman dan tegalan ke pemukiman.
