Groundwater Surface Contour Modeling Using Kriging Method Around JJLS, Purwosari District, Gunung Kidul

Kapanewon Purwosari, Gunungkidul Regency, Special Region of Yogyakarta is one of the areas that still uses groundwater to meet water needs such as household and agricultural needs. Over time, the expansion of development areas such as JJLS has resulted in changes in spatial patterns, including the groundwater conditions within them. Direct data collection in the field, such as data on rivers and residents' wells, can be used as parameters in modeling groundwater conditions in the area. Limited data can be supplemented by using the krigging method with software such as ArcGis to help in groundwater modeling. Based on 36 observation points, including 24 community wells and 12 rivers, interpolation was performed using the krigging method to produce groundwater contour lines in the area around the observation points
