Analysis of salt water distribution in the borobudur plain

Abstract

Abstract Research objectives: mapping the distribution of salt water and knowing the causes of saltwater in the Borobudur Plain. The research population was in the form of community well water, in 6 villages around the Borobudur plain of Magelang Regency. The research variables included the distribution of well water quality (sodium, acid, chloride, salinity, total dissolve solid/TDS) and impact water quality to the community. The results of the study, the distribution of ground water quality in terms of different physical and chemical properties. Candirejo village from the physical and chemical aspects did not match the quality standard, the content of sodium 353-568 mg/l and strong acid content in the form of chloride ranged from 809.9-1639.5 mg/l, while physically DHL at Candirejo ranged from 1,612-3,546 mhos/cm and TDS 1522-1749 mg/l. The best water quality is found in the village of Bumiharjo in terms of both physical and chemical aspects. The cause of salt water in Borobudur Plain was: ground water dominated by alkalis and strong acids with chemical compounds NaCl type of group sulfate water that taste salty and groundwater is dominated by alkaline earth and weak acids, namely water with type (b) semi bicarbonate type.
