“…Interpretasi geometri penyusun batuan dapat memberikan informasi karakteristik akuifer air tanah (Rathinasamy et al, 2019). Informasi penyusun batuan hasil geolistrik atau pengukuran nilai resistivitas dengan pendekatan informasi hidrogeologi dapat memberikan kondisi potensi sumber daya air tanah (Febriarta & Shofarini, 2021;Wicaksono et al, 2020). Berdasarkan latar belakang tersebut, maka tujuan dari penelitian ini adalah untuk mengetahui potensi air tanah (akuifer) pada formasi batuan Gunung Merapi (Qvm) atau formasi tidak terpisahkan pada sebagian lereng kaki Gunung Merapi yang terdiri atas geometri keterdapatan air tanah dan potensi parameter akuifer yaitu kedudukan air tanah dan potensi debit air tanah di Kecamatan Prambanan, Kabupaten Klaten, Provinsi Jawa Tengah.…”

The presence of groundwater in volcanic rock formations is generally found in aquifer lithology in the form of loose deposits. The groundwater potential can be obtained by using the resistivity data approach. The purpose of this study was to determine the potential of aquifer parameters in volcanic formations on the middle slope of Mount Merapi in Prambanan District, Klaten Regency. The characteristics and thickness of the aquifer lithology can be determined by using the resistivity data approach which is correlated with rock material. Potential groundwater aquifer parameters were obtained from pump test measurements to determine the value of transmitivity (T) and value of permeability (K). The resistivity value is measured with a value range of 3 –75 ohm m which is interpreted by the aquifer lithology of loose material in the form of sand with fine to coarse grain sizes. The average thickness of the aquifer lithology is 80 m with free aquifer properties. Potential aquifer parameters in the form of transmitivity (T) of 330.6 m2/day and the value of permeability (K) of 8.03 m/day with an average aquifer thickness of 10 m. This value belongs to the category of high aquifer productivity potential. Keywords: Aquifers, Discharge, Groundwater, Permeability, Resistivity, Transmissivity Abstrak Keterdapatan air tanah pada formasi vulkanik secara umum terdapat di litologi akuifer berupa endapan lepas-lepas. Potensi air tanah tersebut dapat diperoleh dengan pendekatan data resistivitas. Tujuan dari penelitian ini adalah mengetahu potensi parameter akuifer pada formasi vulkanik di lereng tengah Gunung Merapi di Kecamatan Prambanan, Kabupaten Klaten. Untuk mengetahui karakteristik dan tebal litologi akuifer menggunakan pendekatan data resistivitas yang dikorelasikan dengan material batuan. Potensi parameter akuifer air tanah diperoleh dari pengukuran uji pompa untuk mengetahui Nilai transmisivitas/keterusan (T) dan nilai permeabilitas/kelulusan (K). Nilai resistivitas terukur dengan rentang nilai 35–75 ohm m yang diinterpretasikan dengan litologi akuifer material lepas-lepas berupa pasir dengan ukuran butir halus hingga kasar. Ketebalan rata-rata litologi akuifer sebesar 80 m dengan sifat akuifer bebas. Potensi parameter akuifer berupa nilai transmisivitas/keterusan (T) sebesar 330,6 m2/hari dan nilai permeabilitas/kelulusan (K) sebesar 8,03 m/hari dengan ketebalan akuifer rata-rata 10 m. Nilai tersebut termasuk pada katagori potensi produktivitas akuifer tinggi. Kata kunci: Air tanah, Akuifer, Permeabilitas, Resistivitas, Transmisivitas

“…Based on research on the analysis of mercury content conducted by Febriarta (2021) in the traditional gold mining processing area in Paya Ateuk Village, Pasie Raja District, it shows that the Paya Ateuk Village area has experienced mercury pollution (Febriarta et al, 2021;Febriarta & Shofarini, 2021). This is based on testing 3 water samples taken in the upstream, middle and downstream of the rivers in the area.…”

Groundwater vulnerability study research conducted in Paya Ateuk Village, Pasie Raja District uses the SINTACS method. This method is an overlay method that combines 7 primary maps, namely soil texture maps, infiltration maps, slope maps, groundwater depth maps, rock unit maps, aquifer lithology maps, and hydroulic conductivity maps. Then the results of the assessment on the primary map parts are multiplied by the weight on the SINTACS classification and the results are combined into 1 groundwater vulnerability overlay map. The results of the map overlay produce 822 sections that have a range of groundwater vulnerability values at a score of 103.75 – 201.5 with low to high classification. Karst hill areas generally have moderate vulnerability values. Whereas in the lowlands with residential land use has a high vulnerability. This is due to the flat slope with sandstone, and moderate infiltration. Besides that, the texture of the soil is large and the depth of the groundwater is shallow. So that contamination on the surface can easily affect the quality of water in groundwater. Meanwhile, the groundwater vulnerability value is high in a narrow area with the use of paddy fields. Based on measurements of the quality of groundwater in wells owned by residents, it shows that the groundwater in the research location is of good quality. This is due to the large number of natural phytoremediation plants around the research area. Although the quality of groundwater is in good condition. The government as the policy maker still needs to regulate and provide official permits for traditional gold miners who are classified as illegal and continue to monitor the environment around traditional gold processing areas.

Assessment of groundwater vulnerability in the Metro Hilir watershed is necessary because most people use well water to meet basic needs. Identification and spatial analysis are the first steps to determine the potential for groundwater pollution in the area. The SINTACS method was used to assess the intrinsic vulnerability of groundwater using the parameters of groundwater table depth, effective infiltration, material in the unsaturated zone, soil texture type, aquifer media, hydraulic conductivity, and slope. Data processing was carried out by using Geographic Information System (GIS) techniques. Weight scenarios was used based on the hydrological conditions of the study area, namely “Normal Impact” and “Drainage/seepage”. The SINTACS index results was classified into several levels of vulnerability. The high vulnerability class is spread across the east to the south side, while the low vulnerability class is more dominant in the western area. The results of Sensitivity Analysis using the Map Removal technique showed that in both scenarios, soil texture parameters have the highest variation index value of 1.73% in the “Normal Impact” scenario and 2.13% in the “Drainage/Seepage” scenario. Parameters with high variation index values have a sensitive influence on vulnerability class values.
