Abstract
The landscape of Merauke District is swampy area and peat land. This area was formed as a result of continuous sedimentation for millions of years which has lasted until now. As a sedimentation area, the content of lime and other dissolved substances in groundwater in Merauke District is high. This study aims to determine the level of concentration of electrical conductivity (EC) solutes and acid-base (pH) indicators in groundwater. The research sample is groundwater originating from 11 sub-districts in Merauke district with sampling technique using cluster random sampling technique. The results of testing in the laboratory showed that groundwater in Samkai had the highest EC value (2929 μ-S). Meanwhile, the lowest EC level was found in Karang Indah (707 μ-S). In the pH indicator, the largest pH value was found in Kamundu with an indicator value of 9.5 and the lowest pH indicator value was found in Seringgu Jaya sub district with an indicator value of 7.23. The test found that all water samples were alkaline (pH>7) and the EC value was relatively high. By the results of the analysis, it can be concluded that groundwater sources in Merauke District, Papua Province have a fairly large level of viscosity. In addition, the pH indicator shows high level of basicity.
