Analisa Kadar Ammonia pada Air Limbah Industry dengan Menggunakan Metode Spektrofotometer UV-Visible di PT. Shafera Enviro Laboratorium

Abstract

An analysis of Ammonia levels in industrial wastewater has been carried out to determine the quality of industrial wastewater at PT Shafera Enviro Laboratory Jamin Ginting Medan. The purpose of this analysis is to check the water quality of the ammonia level at PT Shafera Enviro Laboratories whether it meets the quality standard limits according to P.16/MENLHK/SETJEN/KUM.1/4/2019. The parameter in this analysis is ammonia (NH¬3). The research was carried out using the fenate method, the number of samples taken was representative of the palm oil mill (PKS). The results of analysis and testing in the laboratory showed that the ammonia level in the factory effluent was between 2.25 - 2.67 mg/L with a concentration of 3.8 - 4.5 mg/L so that it still met the quality standard requirements of P.16/MENLHK/SETJEN/KUM.1/4/2019
