Penentuan Kadar Total Disolve Solid (TDS), Total Suspended Solid (TSS) dan Potential Hidrogen (pH) pada Air Bersih di UPT. Laboratorium Kesehatan Provinsi Sumatera Utara

Abstract

Determination of TDS levels using the gravimetric method found from samples with codes 0144, 0161, 0166, 0175, 0189, and 0194 respectively were 198 mg/L, 290 mg/L, 128 mg/L, 138 mg/L, 238 mg /L, and 264 mg/L. Determination of TSS levels using the gravimetric method found in samples with codes 0144, 0161, 0166, 0175, 0189, and 0194 respectively were 4 mg/L, 3 mg/L, 4.5 mg/L, 6.5 mg/L, 6 mg /L and 4.5 mg/L. And determining the pH using a pH meter found from samples with codes 0144, 0161, 0166, 0175, 0189, and 0194 respectively are 7.50, 7.22, 7.08, 6.92, 6.99 and 7.08. The TDS levels found in samples 1,2,3,4 and 5 meet the clean water quality standards that have been set according to SNI 6989.27:2019, which is 1000 mg/L. The TSS levels found in samples 1,2,3,4 and 5 met the clean water quality standards that had been set according to SNI 6989.3:2019, namely 500 mg/L. The pH levels found in samples 1,2,3,4 and 5 meet the clean water quality standards that have been set according to SNI SNI 6989.11:2019, namely 6.5 – 8.5.
