Abstrak

Longsor yang terjadi pada beberapa bulan belakangan menjadi bencana yang serius di daerah Sumedang, Jawa Barat, Indonesia. Pada awal tahun 2021, terdapat kejadian longsor yang mengakibatkan 64 orang menjadi korban. Telah dilakukan beberapa penelitian oleh pemerintah untuk menentukan penyebab terjadinya longsor di lokasi tersebut. Tujuan dari penelitian ini adalah untuk mendeteksi lokasi lain di daerah ini yang memiliki potensi longsor. Pendekatan pertama yang dilakukan adalah pendekatan regional berdasarkan data satelit untuk mengklasifikasikan informasi potensi berdasarkan data kemiringan lahan dan tutupan lahan dari data remote sensing. Pendekatan kedua adalah pendekatan investigasi secara lokal menggunakan GPR yang merupakan metode elektromagnetik. Metode ini dapat mendeteksi keberadaan microcracking yang terdapat di bawah permukaan untuk mengevaluasi klasifikasi longsor dari data remote sensing.  Berdasarkan analisis microcracking, dihasilkan daerah aman dari longsor dengan klasifikasi secara kualitatif dari potensi tinggi ke rendah.
