The Dieng Plateau is located in the central part of Central Java Province and is surrounded by volcanic cones, namely Mount Prahu to the east, Mount Bismo to the west, and Mount Sindoro to the south. In relation to groundwater resources, the Dieng Plateau is located in the Karangkobar and Wonosobo Groundwater Basin, which are characterized by many springs. This study aims to determine the hydrogeochemical of springs in these groundwater basins located on the Dieng Plateau. Hydrogeochemical analysis was conducted on 16 springs to determine their major ion content. Hydrogeochemical testing with 4 methods, namely the Kurlov Method, Stiff Diagram, Piper Diagram, and Durov Diagram, there are 3 groups of groundwater in springs in the study area, namely 4 Shallow Depth Aquifer Springs with dominant Calcium (Ca2+) ions and dominant Bicarbonate (HCO3−) compounds, 8 Intermediate Depth Aquifer Springs with dominant Calcium (Ca2+) ions and dominant Sulfate (SO42−) and Chloride (Cl−) compounds, and 4 Deep Depth Aquifer Springs with increased alkaline ions (Na+ + K+) and the dominant compound is Chloride (Cl−).
