N2 - Induced Polarization (IP) is one of the Geophysical methods that utilize the polarization properties of the rocks. This method is widely used in metallic mineral exploration. In this method, it is known a specific method that called as Time Domain Induced Polarization (TDIP). The physical modeling of IP is used to study the behavior of TDIP response to the subsurface parameters. The fieldscale physical modeling is the development of the laboratory physical model. This modeling is realized by burying objects with a specific geometry that have contrasting physical parameter to host medium in the area that is not too extensive. Soil is used as host medium, sphere and block object which has variation in metallic mineral content as a target. The extreme targets was also made to evaluate the electrodes measurements. Data acquisitions are using the Dipole-dipole and Wenner configurations. The purpose of this study is obtaining the relations between TDIP response to changes of metallic minerals content. Res2DInv inversion modeling is used to obtain true chargeability and resistivity value in subsurface. The relationship between them is obtained from depth slicing of all inversion results. Evidently, the geometry and position of subsurface objects with contrasting in chargeability and resistivity can be identified with physical modeling fieldscale. Dipole-dipole and Wenner configuration are able to determine the TDIP responses in subsurface. Dipole-dipole configuration has main advantage, it is able to separate chargeability laterally, while Wenner produces deeper penetration. In this research, the relation between chargeability (m) and the iron-ore content (x) of the sphere targets using Dipole-dipole and Wenner configuration are m = 0,07e0,033x and m = 0,87e0,008x, while on the block targets m = 0,21e0,009x and m = 0,79e0,007x respectively. In this research, correlation between the resistivity and the metalic mineral content in the target can not be obtained with good result.
