| dc.description.abstract | The Ciseeng geothermal area is a geothermal potential area in Bogor Regency, tertiary
sedimentary rocks dominate West Java with surface manifestations such as hot springs and
travertine deposits. Gravity and magnetic methods have been used to do study in this field. 79
gravity data and 191 magnetic data are spread out over a distance of 50 meters, with a
measurement area of 3 km x 2 km. In the research area, complete Bouguer Anomaly values
ranged from 56.1 mGal to 59.3 mGal. The total magnetic intensity in the research area was
measured to be between -129.6 and 661.7 nanotesla. The upflow zone can be estimated by
identifying structures in potential geothermal areas. A derivative analysis was applied as the
method (First Horizontal Derivative and Second Vertical Derivative). This method determines
where the geological structure is on track's cross-section. The forward modeling approach is used
to estimate the density distribution of the subsurface model. The FHD and SVD analyses
revealed that a reverse fault existed at L-3, whereas a strike-slip fault existed at L-5 and L-9. The
rocks that make up the research area are alluvium, breccia, and limestone, according to the results
of forward modeling of a 2D cross-section in a North-South direction. With an inaccuracy value
of 9.584% for magnetic data and 0.032% for gravity data, a reverse fault was discovered around
Peyek Mount in a northwest-southeast direction. | en_US |
