| dc.description.abstract | An analysis has been carried out which aims to determine the water quality of the Deli river at PDAM Tirtanadi, the drinking water treatment plant (IPAM) Deli Tua Branch. The purpose of this analysis is to check the quality of Deli river water and the levels of Alkalinity and Hardness in PDAM Tirtanadi Drinking water treatment plant (IPAM) Deli Tua Branch whether it is suitable for use according to PERMENKES RI No. 492/MENKES/PER/IV/2010. The parameters in this analysis are the levels of Alkalinity and Hardness. The results of the analysis on Reservoir Water Analysis levels are 21 mg/L, 35 mg/L, 35 mg/L, and 34 mg/L with an average value of 31.25 mg/L while the hardness level is 64 mg/L, 64 mg/L, 60 mg/L and 66 mg/L with an average value of 63.5 mg/L and for Raw Water at an Alkalinity level of 43 mg/L, 38 mg/L, 41 mg/L and 63 mg/L with an average value of 46.25 mg/L while the hardness levels were 67 mg/L, 59 mg/L, 58 mg/L and 92 mg/L with an average value of 69 mg/L. Where the Alkalinity level is carried out using the Acid-Base Titration method, while the Hardness level is carried out using the Complexometric Titration method. Has met the feasibility/quality standards stipulated in the Minister of Health Regulation No. 492/MenKes/Per/IV/2010 dated April 9, 2020, namely: 200 mg/ L for the level of Alkalinity and 500 mg/L for the level of Hardness. | en_US |
