Bahaya Longsor CMA Kota Bandar Lampung Skoring SIGAbstract
Kota Bandar Lampung memiliki kondisi topografi dan karakteristik geografis yang rentan terhadap bencana, termasuk bencana longsor. Penelitian ini bertujuan memetakan potensi bahaya longsor di Kelurahan Sukarame Dua serta merancang jalur evakuasi dan titik kumpul bagi warga sekolah SDN 01 Sukarame Dua. Penelitian ini menggunakan metode Composite Mapping Analysis (CMA) berbasis Sistem Informasi Geografis (SIG) yang mengintegrasikan beberapa parameter yaitu kelerengan, jenis tanah, curah hujan, dan penggunaan lahan. Hasil penelitian menunjukkan bahwa wilayah penelitian terbagi ke dalam tiga kelas potensi bahaya longsor, yaitu sejumlah 17% kelas rendah, 59,6% kelas sedang, dan 23,4% kelas tinggi yang mencakup seluruh area Kelurahan Sukarame Dua. Dalam menentukan jalur evakuasi dan titik kumpul, penelitian ini menggunakan metode Network Analyst untuk mencari rute yang aman dan terdekat. Berdasarkan hasil pemetaan, SDN 01 Sukarame Dua berada pada zona potensi bahaya longsor yang tinggi sehingga memerlukan strategi mitigasi dan kesiapsiagaan yang lebih optimal. Penelitian ini diharapkan dapat menjadi dasar perencanaan mitigasi bencana bagi sekolah dan masyarakat Kelurahan Sukarame Dua, Kecamatan Teluk Betung Barat, Kota Bandar Lampung.
