Precision agriculture is a land management approach aimed at improving agricultural productivity efficiency by utilizing geophysical methods to examine physical properties such as soil resistivity and soil conductivity to evaluate soil conditions. Geophysical methods commonly used in precision agriculture are the resistivity method for measuring the apparent resistivity (????????) of the soil and the electromagnetic method for measuring the apparent electrical conductivity (????????????) of the soil. The subsurface modeling results for resistivity method show resistivity (?) values ranging from 1.56 - 58.1 ?m. The electromagnetic data modeling results (????????????) show conductivity values of 28 - 115 mS/m. In resistivity data modeling, it is observed that the resistivity value increases toward the surface, indicating a decrease of water content closer to the surface. In the 2D modeling of conductivity data, the value of (????????????) at a depth of 0.5 meters are higher compared to those at a depth of 0.25 meters which suggests that the water content at a depth of 0.5 meters is higher.
