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

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