The increasing population growth and rapid development of Pekalongan in recent years have caused an increase in clean water needs that cannot be fulfilled from surface water due to pollution problems, so people prefer to use groundwater. Therefore, it is necessary to determine the aquifer system to know groundwater sustainability in this area. This study investigates subsurface lithology and aquifer layer thickness to determine the aquifer system. The investigation determined the subsurface lithology using the 1 Dimension Electrical Resistivity method with Schlumberger Configuration. Based on the investigation results, the rock layers in the northern part have resistivity values below 3 Ωm and 11–60 Ωm. The value is predicted by the loose and unconsolidated materials derived from the river and coastal deposits, predominantly sand-clay grain-sized. This layer is interpreted as the primary aquifer in the northern part. The other layer in the northern part, with a resistivity value of 3–10 Ωm, is interpreted as sandy clay and acts as an aquiclude. A layer with a resistivity value of 11–60 Ωm in the south is tuff sand. The tuff sand originates from volcanic rock debris and acts as an aquifer. The layer with a resistivity value of 3–10 Ωm is interpreted as a tuff clay. The tuff clay acts as an aquiclude layer. The layer with a resistivity value of more than 60 Ωm is known as the tuff breccia. The layer is an aquitard and base of the aquifer system.
