<p align="justify">In this thesis the author will map gas pipeline around "Cikarang Bekasi" (CBL) River, Bekasi, West Java by using geomagnetic method. Geomagnetic Methods utilizing values of magnetic field anomaly at each measurement point. Earth's magnetic field is generated from the ionic fluid movement in the outcore layer cause geodinamo effect and generate a magnetic field that moves from the north pole of the Earth's magnetic field toward the south pole of Earth's magnetic field. Earth's magnetic field will induce a rock on subsurface. The value of induced magnetic field depends on the value of material susceptibility. The magnetic field value on measurements must be corrected first by diurnal correction, geomagnetic correction, and the elevation correction, then performed the filtering process. Magnetic field data obtained will be processed using Mag2dc, and Google Earth software. Mag2dc able to model the position of the gas pipeline on the vertical and horizontal position, while Google Earth is used to predict the gas pipeline along the river CBL. The magnetic field anomalies that produced has a different pattern on each measurement, it is because the gas pipeline is a ferrimagnetic material that has a magnetic moments on irregular directions, unlike hydrocarbon that have the same magnetic field anomaly patterns at each measurement point.<p align="justify">
