Abstract

The number of unregistered artesian wells increases every year in the northern slopes of Bromo Volcano, Pasuruan. Artesian wells are used for domestic needs and agricultural irrigation but are not followed by environmentally sound groundwater use. The purpose of this study is to assess the potential for groundwater, groundwater use, wasted groundwater, and recommendations for groundwater management.  The groundwater potential was obtained by measuring the depth of the groundwater table, piezometric surface of artesian wells, and geoelectrical data. Water uses were obtained from calculations based on the Indonesian National Standard. The amount of wasted groundwater was obtained by comparing the groundwater potentials, groundwater uses, and groundwater discharges from unregistered artesian wells. Water transfer was assessed by selecting unregistered artesian wells with discharges able to fulfill the water demands of each village. Groundwater in the Sub-Districts of Gondang Wetan and Winongan has high potential consisting of 1 unconfined aquifer group and two confined aquifer groups. Gondang Wetan and Winongan Sub-Districts are characterized as wasting groundwater potential through unregistered artesian wells. The discharge flow of unregistered artesian wells exceeds the water needs (>100%) in Winongan and Gondang Wetan Sub-Districts. Groundwater can be managed by water transfer, closure of artesian wells, and regulation of artesian wells use. Water can be transferred to areas not covered by Artesian wells in 20 villages. The number of artesian wells used for water transfer is 20 with a discharge of 5-20 liters/s.

Abstract

For the population of Playen District, Gunungkidul Regency, karst springs serve as the primary water sources because surface rivers are rare in karst areas and, if present, the quality of their water is reportedly less than that of the springs. In the spring water utilization, local wisdom is incorporated into the management and has so far contributed to sustainability. Since only a few studies have examined local wisdom and its correlation with changes in spring management pattern, this research initiates the provision and dissemination of information on karst spring management that is applicable elsewhere. It was designed to scrutinize the local wisdom and regulatory measures implemented at many springs in Playen District. Detailed data were obtained by in-depth interviews with four key informants responsible for managing springs block 1 (Gedad, Grunggung, and Karangkulon Springs), 2 (Banyusoco and Sungai Oyo), 3 (Dung Poh, Nganding, Umbul, and Jambe), and 4 (Ngrunggo and Ngrasih). Through qualitative descriptive analysis, the research found that the laying of offerings at springs in blocks 1 and 2 during traditional celebratory ceremonies had been abandoned, but cleaning activities at and around these springs as part of the local wisdom sustained. In the context of utilization, the spring management had changed from direct manual withdrawal to indirect systematized one that used pipes with gravitational water flow system (block 1) to distribute spring water to villagers’ houses (block 2). On the contrary, local wisdom like offerings and cleaning activities at and around the springs in blocks 3 and 4 was preserved. Their management had changed from manual extraction to gas-fueled water pumping systems, which were later replaced with electricity-powered pumps (block 3), and to indirect withdrawal through pipelines with pump-generated flows (block 4). To manage the springs in all blocks and their sustainable utilization, the people of the district still adopt local wisdom. Besides, they no longer collected water directly at springs but have switched to water distribution technology like pumps and pipelines instead.
