Abstract

English

Hardness is a type of groundwater that is influenced by the influx of Ca2+ and Mg2+ ions originating from limestone sources in the burial environment, which react with carbonic acid (H2CO3). Based on surveys and geochemical computational studies of the Koya Tengah sub-district, Muara Tami District, Jayapura City, it is formed in the Jayapura Formation rock layers (CaCO3 limestone layers) and alluvial soil resulting from the deposition of organic and inorganic materials, so through this research groundwater hardness testing was carried out using the titration method. complexiometry. The analysis results show that the hardness concentration of water sample 1 is 464 ppm and 414 ppm for sample 2. This concentration level shows that water samples 1 and 2 are included in the challenging category in general, according to some literature, namely more than 300 ppm. This category can also be confirmed by the pH of samples 1 and 2, which tends to be alkaline with a value of 7.08 for sample 1 and 7.44 for sample 2, and the TDS value of sample 1 is 315 ppm and 290 ppm for sample 2.

The analysis results show that the hardness concentration of water sample 1 is 464 ppm and 414 ppm for sample 2. This concentration level shows that water samples 1 and 2 are included in the very hard category in general, according to some literature, namely more than 300 ppm. This category can also be confirmed by the pH of samples 1 and 2, which tends to be alkaline with a value of 7.08 for sample 1 and 7.44 for sample 2, and the TDS value of sample 1 is 315 ppm and 290 ppm for sample 2.
