IDENTIFICATION OF RIVER WATER QUALITY YARN NETWORK AT THE TIBU NANGKLOK WATER TREATMENT INSTALLATION CENTRAL LOMBOK PDAM BASED ON PHYSICAL AND CHEMICAL PARAMETERS

Abstract

The river is one of the easiest shallow water sources to find and use. Benang Kelambu River is a river located in Aik Berik village, North Batukliang sub-district, Central Lombok. Besides acting as a source of water, the thread netting river is also known as a tourist spot with its famous waterfall. Because it is a tourist attraction, of course, the quality of the thread netting river water needs to be investigated, whether it is still drinkable or has been polluted.This study uses an experimental method by analyzing water quality based on two parameters, namely physical parameters by measuring (temperature, pH, conductivity and TDS), while the chemical parameters measured are (Fe, Cu, and Mn).From the results of research that has been carried out, it is known that from the two water samples that have been studied in terms of physical parameters, both samples are still below the threshold, so they are still considered safe. Meanwhile, in terms of chemical parameters, both samples contained heavy metals which were far below the threshold.
