“…Berdasarkan nilai parameter-parameter terukur seperti DHL dan kandungan ion-ion terlarut dalam contoh air (Na + , Ca 2+ , Mg 2+ , HCO3 -, Cl -) yang telah dideskripsikan dalam publikasi sebelumnya (Siswoyo et al, 2019), dapat dihitung nilai SARadj dan nilai IWQI untuk tiap contoh air irigasi dari mata air karst di lokasi penelitian. Hasil perhitungan nilai SARadj ditunjukkan dalam Tabel 2.…”

“…Nilai SARadj yang diperoleh berdasarkan perhitungan dalam Tabel 2 di atas lebih rendah dibandingkan hasil perhitungan nilai SAR (Siswoyo et al, 2019). Secara umum, nilai SAR merepresentasikan indeks bahaya natrium (alkalinitas) air yang digunakan untuk irigasi.…”

“…Rendahnnya nilai SAR berpengaruh pada rendahnya adsorpsi natrium oleh tanah, sehingga struktur tanah tetap dapat terjaga dan tanaman dapat tumbuh secara optimal (Hidayat et al, 2016). Berdasarkan nilai SARadj hasil perhitungan di atas dan nilai parameter model lainnya (Na + , HCO3 -, Cl -, dan DHL) (Siswoyo et al, 2019) diperoleh hasil perhitungan nilai IWQI dan penentuan batasan penggunaan air untuk irigasi seperti ditunjukkan dalam Tabel 3.…”

The main problem in open-pit mining activities is the remaining mine openings as voids after mining activities end. The interaction between rock, water and air can cause dissolved rock chemical elements to cause polluted water. A study of this phenomenon was carried out in a void in the Tanjung area. An abandoned iron ore mine left a void with a depth of 13 meters. Furthermore, around the void existed two stockpiles of mined ore. Therefore, the void and the stockpiles may act as pollutant sources that can reduce surface water quality. In the rainy season, the water from the void flows out as a runoff downstream through a tributary. This study is intended to analyze the chemical concentration of runoff water from the void. Field observation was done to identify rock formation, and measured pH, turbidity, total dissolved solids (TDS), and electrical conductivity(EC) of water on site, and collected 10 water samples from the river and tributary. Field data was completed with laboratory chemical analysis for water major elements of K+, Na+, Ca2+, Mg2+, Cl−, SO4 2−, CO3 2− and HCO3. The results of the analysis of the TDS test with a minimum value of 4 mg/l and a maximum of 607 mg/l. turbidity value 0 to 21.4 NTU, pH value 2.9 to 8.2, EC value 165.6 ms/cm to 316 ms/cm. Plotting the concentration of the major elements into Trilinear Piper Diagram shows that water is as CaMgSO4 water type based on their major elements. Changes in water quality at voids, stockpiles and areas around the mine indicate that potential water pollution is generated from existing stockpiles.

The emergence of springs and underground rivers is one of the characteristics of a karst landscape that is formed due to the karstification process in which carbonate rocks are dissolved by water to form cavities or channels. Karst Pacitan is an area located in parts of Donorojo, Punung, and Pringkuku sub-districts. Geologically, the area is included in the Wonosari Formation unit, which is composed of limestone. The hydrogeology of the Pacitan karst is part of the Wonosari Groundwater Basin. Similar to other karst regions, in the surface is difficult to find water. Naturally, the emergence of springs is used by the local community to help them meet the water needs for daily life. This research was conducted by measuring several groundwater samples from springs in the karst region of Pacitan Regency. The purpose of this study is to determine springs groundwater quantity and quality in the research area. In order to achieve above objectives, groundwater observation includes measurement of springs discharge, checking physico-chemical parameters including pH, Total Dissolved Solid (TDS), Electrical Conductivity (EC), and temperature. Based on the measurement results, the springs in the Karst Pacitan area have a discharge range between 0.01 to 89.28 L/s. According to WHO standards and the Regulation of the Minister of Health Republic of Indonesia the groundwater in the Pacitan Karst area is accepted as drinking water based on their physicochemical parameters.
