| Summary: | Geophysical studies using 2D geoelectric measuring methods have been carried
out in the area of Kancah hot springs is located on the border of Parongpong and
Lembang District, West Bandung Regency, West Java Province. This research was
conducted to obtain an overview of the existence of hot springs that appear to be
connected with the activities of the Lembang Fault which is in the south of Hot
springs or related to volcanic activities of Mount Tangkuban Perahu is north of the
research site. The collection of research data on the Kancah hot springs field is
done using the method of 2D Geoelectric resistivity parameters using the equipment
resistivity meter model Syscal Pro Switch 48 from IRIS Instruments with multielectrode
system using dipole-dipole electrode configuration with the shortest
electrode spacing of 10 meters. The 2D geoelectric measurement trajectory was
placed in the Kancah hot springs in the south-north, southwest-northeast, west-east
and southeast-northwest with a trajectory length of 470 meters and the Kancah hot
springs was placed on the center position of each measuring track with the aim of
obtaining a radial representation of the subsurface layer and structure condition of
Kancah Hot Springs research area
Based on the results of a cross section of 2D resistivity model below the surface of
the study area, Radon-222 isotope data, and hydrogeochemistry data relating to
the Kancah hot springs, it gives an illustration that the aquifer carrying water
flowing out of the Kancah hot springs comes from the direction of Mount
Tangkuban Perahu, there are indications of zones hydrothermal structures below
the surface of the Kancah hot springs, Kancah hot springs associated with volcanic
reservoirs of Mount Tangkuban Perahu, Kancah hot springs belong to the category
of deep groundwater type hot springs, and the Kancah hot springs are not
connected with Lembang Fault activities.
