“…The relationship between the Karaha Bodas and Talaga Bodas fields according to hydrogeochemical data, explains that these two fields are included in one geothermal system with the Talaga Bodas field as an upflow zone and the Karaha Bodas field as an outflow zone with different fluid origins and heat sources or having two heat sources or heat sources. 2018) and Yosephin et al (2019).…”

“…The structure that is around the manifestation has an orientation of almost parallel to the orientation of the regional structure in the Talaga Bodas and Karaha Bodas complexes which is very influential on the appearance of manifestations in the geothermal system of the outflow zone, namely the Karaha Bodas field. The Karaha Bodas and Talaga Bodas field complexes are influenced by the regional structure located in the south of Mount Karaha or Gunung Putri, or more precisely, between Mount Ngantuk and Mount Jurang which is also contained in the conceptual model of Yosephin et al (2019) identified as one control the discharge of the manifestation making a part of the outflow zone.…”

The Karaha Bodas and Talaga Bodas are two geothermal fields which are located in Tasikmalaya, West Java. The Karaha Bodas and Talaga Bodas fields have geothermal prospects with the discovery of several surface manifestations in the form of hot springs, fumaroles, and acid lakes. The orientation of the structure that developed in the two fields showed a different orientation. However, no research explains the relationship between the geothermal system in the Karaha Bodas field and the Talaga Bodas field, and the potential of Cipacing and Pamoyanan. The survey location is in Garut and Tasikmalaya, West Java. The investigation method used is qualitative (morphostructure analysis) and quantitative (hydrogeochemical analysis) methods. Data processing using DEM (Digital Elevation Model) for morphostructure analysis, and water chemistry from the Karaha Bodas, Talaga Bodas, and Cipacing fields for hydrogeochemical analysis. The analysis shows that the relationship between the Karaha Bodas and Talaga Bodas geothermal systems is typical a geothermal system, with having two different heat sources, the Talaga Bodas field as an upflow zone, and the Karaha Bodas field with Cipacing and Pamoyanan potentials as an outflow zone.Keywords: Conceptual model, geothermal system, hydrogeochemical, Karaha Bodas, morphostructure, Talaga Bodas.

“…This section then acted as a base for making the conceptual model of the Galunggung geothermal area (Figure 11). The conceptual model was also made by inferring from various sources (Henley & Ellis, 1983;Tripp et al, 2002;Reynolds, 2011;Yosephin et al, 2019). The estimated reservoir boundary and cap rock were interpreted from the B-B' cut profile.…”

Galunggung volcano area is a geothermal concession area that adjacent with Karaha-Cakrabuana concession area with a distance around 1 km. Indonesian Government planning to build power plant in 2025 so additional research needed to support the plan. Gravity survey could help in identifying permeable structure (fault) as well as heat source to a certain depth. The results of data processing showed the presence of faults seen on the FHD, SVD, and ABL residual maps, while for heat sources it was shown from the closed contour patterns on the ABL, residual, and regional maps. Derivative analysis in strengthens the position and type of fault from the match between the maximum FHD value and zero SVD value. From these results, identified the existence of three faults in the study area and were all identified as normal faults. 3D modelling gave a picture of density contrast in research area. From the section profile that pass through Galunggung and Telaga Bodas crater, heat source was interpreted as density with value 2.8 – 3.0 gr/cm3 and marked by orange to red color that coincide below Galunggung crater and continoued to Talaga Bodas crater at depths below -3000 masl. This indicate that both concession area was connected.
