This research was conducted in the South Konawe area, especially in other geothermal using satellite image data, namely the Global Gravity Model Plus (GGMPlus) which has been developed with high resolution and a distance between points of -220m. Several studies have been conducted basement 3D modeling using measurement data but have not found basement 3D modeling in the Lainea area based on GGmplus data.Gravity data modeling (residual anomaly) was inverted using the GRAV_D_In-based MATLAB program. The Grav_D_In program requires several parameters, namely anomaly depth estimation, area area, wavenumber range for low-pass filters, density contrast, and widowing. The result of the inversion of the basement interface 3D model has a depth ranging from 980m to 1540m. The results of the basement contour pattern overlay with the structural pattern show that the structural pattern partially follows the basement contour pattern. An overlay of the basement model of the study was carried out using field data in the topography, that the basement model intersected in the use of satellite image data with measurements. The second basement pattern intersects but has different depths
