Penentuan Kadar Kesadahan Total dan Total Dissolve Solid (TDS) pada Air Bersih di Balai Teknik Kesehatan Lingkungan dan Pengendalian Penyakit (BTKLPP) Kelas I Medan

Abstract

Analysis of total hardness and Total Dissolve Solid (TDS) in clean water at the Center for Environmental Health Engineering and Disease Control (BTKLPP) Class I Medan has been carried out. Determination of total hardness itsing the titrimetric method and the determination of Total Dissolve Solid (TDS). From the resi,lts obtained, the hardness for clean water sample 1: 70 mg/L, sample 2: 98mg/L, sample 3: 146mg/L, sample 4: 118mg/L, sample 5: 56mg/L. From the results obtained, the Total Dissolve Solid (TDS) levels were 569 mg/Land 580 mg/L. From the results obtained based on Permenkes No. 32 of2017 the maximi,m value of.total hardness is 500 nzg/L, the maximi,m vali,e o_f Total Dissolve Solid (TDS ) of 1000 mg/L. The results of this analysis indicate that the clean water samples meet the quality standards set according to Permenkes No 32 of 2017.
