“Fractal” is a geometry that is specified by a non-integer number of scaling system called fractal dimension. In this study, fractal geometry analysis was applied to unravel groundwater exploration problems in the Gunungsewu Hills and the Progo Dome, Central Java, Indonesia. The Gunungsewu Hills is a karstic terrain with conduits, dolines, caves, and subterraneous rivers, while the Progo Dome is a volcanic landform with intensive joint dissections, low permeability fractured aquifer, complex groundwater flow type, and various phreatic water levels. In the Gunungsewu Hills, fractal analysis was utilized to determine the existence of underground flow system. Based on the distribution of fractal dimensions of the fracture patterns, Gunungsewu Area can be divided into three units with different fractal dimensions, i.e. Unit A with fractal simension 0.000 < D < 1.099, Unit B with fractal dimension 1.100 < Ds < 1.299, and Unit C with fractal dimension 1.300 < D < 1.460. Underground flow systems generally occur in Unit C. In the Progo Dome fractal analysis was used to delineate the locations of groundwater discharge. The area can be divided into four zones with different fractal dimensions, i.e. Zone A with fractal dimension D <1.409, Zone B with fractal dimension 1.410 > D >1.609, Zone C with fractal dimension 1.610 > D > 1.809, and Zone D with fractal dimension D > 1.810. The most potential division where to find spring is the zone with fractal dimension 1.410 - 1.609.
