The research area has two geothermal system’s prospect, ie Gede-Pangrango and Pancar that covering Cianjur, Sukabumi, and Bogor, West Java. Determination of geothermal system’s conceptual model and recharge area are purpose of this research. The main data are stable isotope 18 O and 2 H from cold springs and river water, also secondary data as complement. Gede-Pangrango geothermal system has two hot springs, chloride-sulfate water (51°C) and chloride-bicarbonate water (40°C). Solfatar (167°C) and fumarole (70°C) are at the Mt. Gede’s peak. It’s parent fluid has temperature (t Na-K )=275-295°C. Pancar geothermal system has two hot springs, sulfate water (54°C) and chloride-sulfate (66°C). It’s parent fluid has temperature (t Na-K )=190-210°C. Based on geophysical data, the reservoir rock of Gede-Pangrango is in volcanic rock, at elevation 250 to -500 m and Pancar is in sedimentary rock, at elevation alteration -1000 to -1750m. Whereas the cap rock is in alteration rock of volcanic and sedimentry. The 18 O and 2 H isotope analysis shows the recharge area of Gede-Pangrango and Pancar geothermal system at elevation 1100-1156.8 m and 853.5 – 899.12 m plus latitude 9263000-9263500 mS and 9265300-9265800 mS.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Conceptual model,Geophysical data,Geothermal systems,Isotope analysis,Recharge area,Reservoir rock,Secondary datum,Stable isotopes[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1755-1315/212/1/012044[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
