<![CDATA[In recent years, Indonesia has often been hit by various disasters, one of which is the Landslide. Landslides cause many casualties, both life and property. This study aims to: determine areas prone to landslides in the Takapala watershed, Jeneberang sub-watershed. This research approach uses land units derived from soil maps, slope maps, landform maps, and land use maps to produce 30 land units. The research variables used were rainfall, rock types, slope, soil texture, soil permeability, thickness of soil solum, depth of rock weathering, steep walls, land use, and vegetation density. The method used in this research is overlay with Geographic Information system. The sample was determined by purposive area sampling. The results showed that there are two levels of vulnerability to landslides, namely; Sufficiently Vulnerable covering an area of 3,211.30 Ha (81.44%) located in the upstream, middle and downstream parts of the watershed, the Vulnerable level covering an area of 731.69 Ha (18.56 %), spread over the upstream, and middle of the watershed. Factors that affect landslides in this area are mutually supporting one variable with another variable. Serious attention is needed so that the landslide-prone level does not increase to become very vulnerable.AbstrakBeberapa tahun terakhir Indonesia sering dilanda berbagai bencana, salah satunya bencana Longsor. Bencana longsor menimbulkan banyak korban baik jiwa maupun harta benda. Penelitian ini bertujuan untuk: mengetahui daerah rawan bencana longsor di DAS Takapala Sub DAS Jeneberang. Pendekatan penelitian ini menggunakan satuan lahan yang diturunkan dari peta tanah, peta lereng, peta bentuklahan, dan peta penggunaan lahan sehingga menghasilkan 30 satuan lahan. Variabel penelitian yang digunakan adalah curah hujan, jenis batuan, kemiringan lereng, tekstur tanah, permeabilitas tanah, ketebalan solum tanah, kedalaman pelapukan batuan, dinding terjal, penggunaan lahan, dan kerapatan vegetasi. Metode yang digunakan dalam penelitan ini yaitu overlay dengan system Informasi Geografis. Sampel ditentukan secara purposive area sampling. Hasil penelitian menunjukkan bahwa terdapat dua tingkat kerawanan bencana longsor yaitu; Cukup Rawan seluas 3.211,30 Ha (81,44 %) terdapat di bagian hulu, tengah dan hilir DAS, tingkat Rawan seluas 731,69 Ha (18,56 %), tersebar di bagian hulu, dan tengah DAS. Faktor yang berpengaruh terhadap longsor di wilayah ini yaitu saling mendukung variabel satu dengan variabel lainnya. Perlu perhatian yang serius supaya tingkat rawan longsornya tidak meningkat menjadi sangat rawan.]]>
