Abstract: Geophysical research was carried out by using the Magnetotelluric (MT) method on X geothermal exploration to determine the distribution of resistivity and geothermal reservoir zones. The data included nine measurement points with TE-TM invariant mode from two-dimensional modeling. Data were processed by using secondary data from the acquisition process and then utilizing SSMT2000, MTEditor and Win Glink Software. The results shown in this study were in the form of resistivity and subsequent phases with the North-South trending geological conditions. From the analysis obtained in the two-dimensional modeling, there were three distribution zones of resistivity including low, medium and high resistivity distributions. Low resistivity distribution zones of 4-14 Ωm was estimated to be clay cap, the zone of moderate resistivity distribution of 19-159 Ωm was estimated to be reservoir rock which controls the appearance of hot water manifestations and the zone of high resistivity distribution >216 Ωm was estimated to be rock (basement) which is a geothermal source of the Bora area.
