Abstract

Kejadian bencana longsor di Kecamatan Megamendung tahun 2017 – 2020 terjadi sebanyak 60 kejadian yang menyebabkan penduduk terpapar sejumlah 545 jiwa, 180 unit tempat tinggal mengalami kerusakan ringan hingga berat serta perkiraan kerugian fasilitas umum dan kritis sebesar Rp369.000.000. Tujuan penelitian ini mengetahui tingkat kerentanan longsor tiap desa. Metode deskriptif kuantitatif digunakan untuk menghitung dan mendeskripsikan seluruh hasil perhitungan parameter kerentanan. Populasi dan sampel penelitian ini yakni 12 (dua belas) desa di Kecamatan Megamendung. Pengolahan data dilakukan dengan cara memberikan skoring dan bobot pada tiap parameter. Tingkat kerentanan bencana longsor dibagi menjadi tingkat kerentanan rendah, sedang dan tinggi. Hasil pengolahan semua parameter menujukan hasil tingkat kerentanan di lokasi penelitian berkategori tinggi tersebar di 5 desa yaitu Cipayung, Cipayung Girang, Gadog, Sukagalih dan Sukamanah. Tingkat sedang tersebar di 4 desa yaitu Megamendung, Pasir Angin, Sukamahi dan Sukaresmi. Tingkat rendah tersebar 3 desa yaitu Kuta, Sukamaju dan Sukakarya. Hasil tumpang susun (overlay) peta bahaya longsor dengan peta kerentanan total menghasilkan peta kerentanan bencana longsor. Persebaran kerentanan bencana longsor dominan kategori sedang. Secara umum, tingkat kerentanan longsor tingkat rendah terdapat di Desa Kuta, Sukakarya dan Sukamaju. Tingkat tinggi terdapat di Desa Cipayung, Cipayung Girang, Gadog, Sukagalih dan Sukamanah. Perbedaan tingkat kerentanan bencana longsor tiap desa memengaruhi dampak penduduk terpapar dan kerugian saat terjadi bencana. Tingkat kerentanan bencana longsor tinggi di suatu desa akan berpotensi menimbulkan penduduk terpapar dan kerugian yang lebih besar. The landslide disaster in Megamendung District in 2017 - 2020 occurred as many as 60 events that caused the population to be exposed to a total of 545 people, 180 residential units suffered minor to severe damage and an estimated loss of public and critical facilities of IDR 369,000,000. The purpose of this study was to determine the level of vulnerability to landslides in each village. Quantitative descriptive method is used to calculate and describe all the results of the calculation of vulnerability parameters. The population and sample of this research are 12 (twelve) villages in Megamendung District. Data processing is done by giving a score and weight for each parameter. The level of vulnerability to landslides is divided into low, medium and high vulnerability levels. The results of processing all parameters show the results of the level of vulnerability in the research location with a high category spread over 5 villages of Cipayung, Cipayung Girang, Gadog, Sukagalih and Sukamanah. The medium level is spread over 4 villages of Megamendung, Pasir Angin, Sukamahi and Sukaresmi. The low level is spread over 3 villages of Kuta, Sukamaju and Sukakarya. The result of overlapping (overlay) landslide hazard map with the total vulnerability map produces a landslide susceptibility map. The distribution of vulnerability to landslides is dominant in the medium category. In general, low levels of landslide susceptibility are found in the villages of Kuta, Sukakarya and Sukamaju. High levels are found in the villages of Cipayung, Cipayung Girang, Gadog, Sukagalih and Sukamanah. The difference in the level of vulnerability to landslides in each village affects the impact of the exposed population and losses when a disaster occurs. Ahigh level of vulnerability to landslides in a village will potentially cause exposed residents and greater losses.
