This study was conducted to design a forward and inverse modeling to obtain the response of gravity anomalies and subsurface model parameters based on some models of anomalous object such as semi-infinite horizontal sheet and vertical faulted sheet models using matlab software. The design of this models are expected to be applied to detect the presence of faults below the earth's surface by gravity anomaly data in this case primary and secondary data. Gravity anomaly inversion performed using the non-linier inversion approach to solve the mathematical model of the subsurface anomalous object. In this research inversion models performed using unconstrain inversion and constrain inversion to look for some model parameters such as rock density, depth and thickness of anomalous object. Keywords: Gravity anomaly; forward modeling; inverse modeling
