Abstract

the selection of a certain region as an area for groundwater recharge requires priority on the development of a region. Groundwater recharge area has an important role in maintaining a clean water supply in an urban area.One of the impacts of the environmental damage is the damage to the potential for groundwater supplies. This environmental damage is caused by changes in land use, especially in areas of groundwater recharge, residential and industrial development as well as uncontrolled pumping of groundwater. If this happens for a long period, it can disrupt the hydrological cycle system which results in decreased quality and quantity of groundwater, flood, erosion and landslides, and seawater intrusion. Therefore, the selection of a certain region as an area for groundwater recharge requires priority on the development of a region. Groundwater recharge area has an important role in maintaining a clean water supply in an urban area. The urban area is an area that experiences rapid development, especially changes in land use that have turned into residential and industrial areas. In this discussion, the method of the Analytical Hierarchy Process (AHP) was used to determine the priority scale of the catchment area development in the city of Semarang. The AHP method was used to analyze data that has a variety of dimensions simultaneously so that it is based on the data contained in the variables used in identifying the area. The results of the analysis can produce 10 priority areas for groundwater
