Abstract

INDONESIA : Salah satu metode geofisika yang dapat digunakan untuk mengetahui potensi li- kuifaksi adalah metode resistivitas geolistrik. Secara geologi kelurahan Cimenerang (Cimincrang), Gedebage, Bandung memiliki struktur tanah berupa pasir tufaan serta endapan alluvium yang berumur kuarter, sehingga memiliki potensi terjadinya likuifaksi. Ditambah lagi wilayah Gedebage, Bandung memiliki muka air tanah yang dangkal. Data pengukuran geolistrik konfigurasi Schlumburger dimodelkan dengan software SimPEG. Nilai resistivitas yang diperoleh di daerah penelitian berkisar antara 75 - 800 Ω/m yang merupakan rentang dari alluvium berupa pasir, kerikil dan lempung berpasir serta 3 - 52 Ω/m yang merupakan rentang dari pasir tufaan. Hasil ini mengkonfirmasi potensi terjadinya likuifasi di daerah penelitian. ENGLISH : One of the geophysical methods that can be used to identify potential liquefaction is a geoelectric method. Geologic village of Cimenerang (Cimincrang), Gede bage, Bandung has a land structure in the form of Tufaan sand and a quarter-age of alluvium deposits, thus having the potential occurrence of liquefaction. In addition to the Gedebage area,Bandung has a shallow groundwater face. Schlumberger Configuration Geoelectric Measurement Data is modeled with SimPEG software. The resistivity value obtained in the research area ranges from 75- 800 Ω/m which is the range of alluvium of sand, gravel and sandy loam and 3 - 52 Ω/m ranges from the Tufaan sand. These results confirm the potential occurrence of liquefaction in the research area.
