Abstract

Pada penelitian ini, telah diidentifikasi bidang gelincir dan tipe tanah longsor yang terdapat pada Desa Bantai Kecamatan Bonti Kabupaten Sanggau dengan menggunakan metode geolistrik konfigurasi Wenner-Schlumberger. Pengambilan data dilakukan pada empat lintasan. Panjang setiap lintasan adalah 117 meter, sedangkan jarak elektroda terkecil adalah 3 meter. Hasil analisa penampang resistivitas dua dimensi (2D) dari empat lintasan menunjukkan bahwa bidang gelincir tanah longsor berupa batu gamping dengan nilai resistivitas antara 945 Ωm sampai 3518 Ωm. Bidang gelincir tanah longsor di daerah penelitian terdapat pada kedalaman 1-12 meter dengan tipe tanah longsor berupa tipe translasi.

 

Kata Kunci : bidang gelincir, geolistrik, resistivitas, Wenner-Schlumberger
