Arahan Mitigasi Bencana Kawasan Rawan Longsor di Kecamatan Tinggimoncong Kabupaten Gowa

Abstract

Abstract. This study aims to determine the level of vulnerability to landslides and to formulate mitigation directions and evacuation routes for landslides. This research is qualitative as a material for consideration as well as reference material in analyzing descriptively. Research variables include determining the level of vulnerability including slope, rainfall, land use, soil type, and geology. Scoring and ovelay (superimpose) analysis methods, in determining the level of vulnerability using the Geographic Information System (ArcGis) application. Based on the results of the overlay (superimpose) and the scoring of each variable resulting in a low level of vulnerability, medium vulnerability, and high vulnerability then disaster mitigation directions are proposed in the form of structural and non-structural mitigation as well as disaster evacuation routes.   Abstrak. Penelitian ini bertujuan untuk mengetahui tingkat kerawanan tanah longsor serta merumuskan arahan mitigasi dan jalur evakuasi bencana tanah longsor. Penelitian ini adalah kualitatif sebagai bahan pertimbangan serta bahan rujukan dalam menganalisis secara deskriptif. Variabel penelitian diantarannya penentuan tingkat kerawanan diantaranya kemiringan lereng, curah hujan, penggunaan lahan, jenis tanah, dan geologi. Metode analisis skoring dan ovelay (superimpose), dalam penentuan tingkat kerawanan dengan menggunakan aplikasi Geographic Information System (ArcGis). Berdasarakan hasil overlay (superimpose) dan skoring masing – masing variabel menghasilkan tingkat kerawanan rendah, kerawanan sedang, dan kerawanan tinggi kemudian diusulkan arahan mitigasi bencana berupa mitigasi struktural dan non stuktural serta jalur evakuasi bencana.
