| Summary: | The Radiomagnetotelluric (RMT) method is an electromagnetic technique that
utilizes signals from radio transmitters in the frequency range of 10 kHz to 1 MHz.
Due to the limited frequency range, RMT is typically used for shallow
investigations. The RMT method is still relatively new, with most research
conducted in Europe. This study represents the first application of the RMT method
in Indonesia. Data processing was carried out using Tensor-M and mtpy, and 2D
inversion results were obtained with Occam2DMT. The survey was conducted in
the Rancaciung Field, Neglasari Village, Limbangan District, Garut Regency. Data
acquisition was collected from three profiles with a total of 18 stations, spaced 20
meters apart. From the RMT data acquisition, the resistivity range obtained was
100 – 105 Ohm m. 2D inversion was applied to each profile and compared with
reference values and available geological information. The results indicate that the
RMT method can be applied in the study area and is a reliable approach for shallow
subsurface exploration.
