Pemetaan Multi Rawan Bencana di Kabupaten Semarang
Abstrak Kabupaten Semarang merupakan wilayah yang berpotensi mengalami bencana alam seperti tanah longsor, kekeringan dan banjir. Fenomena tersebut dapat terjadi karena berbagai faktor seperti letak wilayah, karakteristik wilayah, dan aktivitas manusia. Penelitian ini bertujuan untuk mengidentifikasi sebaran spasial wilayah yang rawan terhadap bencana longsor, kekeringan, dan banjir di Kabupaten Semarang secara sekaligus. Hasil berupa peta rawan bencana longsor, kekeringan, dan banjir diperoleh melalui hasil pemberian kelas dan pembobotan menggunakan metode Analytic Hierarchy Process (AHP) serta pohon kriteria menggunakan Spatial Multi-Criteria Evaluation (SMCE) yang kemudian dilakukan tumpang tindih untuk menghasilkan peta multi rawan bencana. Hasil penelitian menunjukkan bahwa tingkat kerawanan bencana Kabupaten Semarang didominasi oleh kategori agak rawan, diikuti secara berturut-turut oleh kelas aman dan kelas rawan. Diketahui bahwa sebagian besar pegunungan struktural merupakan daerah yang agak rawan dan sebagian lainnya termasuk rawan, sedangkan lereng kaki merupakan bentuklahan yang dikategorikan paling aman. Dominasi kategori agak rawan tersebut memerlukan adanya mitigasi sebagai upaya mengurangi risiko bencana.
