Penentuan Kadar Amonia Nitrogen pada Air Reservoir dengan Metode Nessler pada Instalasi Pengolahan Air Minum PDAM Tirtanadi Sisingamangaraja

Abstract

Determination of amonia nitrogen levels i11 reservoir water usi11g the nessler method at the drinking water treatment plant of PDAM Tirtanadi Sisingamagaraja has been carried out. Examination of Ammo11ia Nitroge11 levels was carried out using the nessler method using a spectriphotometry DR-3900 with the addition of 3 drops of Mineral Stabilizer,3 drops of Polyvinyl Alcohol Dispersing Agen, and 1 mL of Nessler reagent. From the analysis of the determination of Ammonia Nitrogen levels that have been carried out i11 the Water Reservoir, Ammonia Nitrogen levels of 0.07 Mg/L were obtained. Based 011 the data obtained, the levels of ammonia nitrogen in the reservoir water have met the water quality standards by the Minister of Health of the Republic of Indonesia No.492/MENKESIPERIJV/2010.
