Analisis Kadar Total Suspended Solid (TSS) pada Limbah Cair Menggunakan Metode Spektrofotometer DR 3900 di UPT. Laboratorium Dinas Lingkungan Hidup dan Kehutanan (DLHK) Provinsi Sumatera Utara

Abstract

A study has been carried out which aims to determine the quality of water at UPT.Laboratory of the environmental and forestry service of North Sumatra province, whether it is in accordance with the provisions of the waste water quality standard No. 5 of 2014. The parameters used in this analysis are Total Suspended Solid (TSS) levels. ). The method used was the DR 3900 spectrophotometer. From the research results it was found that in sample code 53/LC/01/23 the TSS level was 38 mg/L, in sample code 54/LC/01/23 the TSS level was 21 mg/L, in code sample 55/LC/01/23 the TSS level was 64.3 mg/L, in sample code 56/LC/01/23 the TSS level was 50.7 mg/L and in sample code 58/LC/01/23 the TSS level is 10 mg/L. In accordance with the regulation of the Minister of Environment of the Republic of Indonesia No. 5 of 2014 concerning waste water quality standards, there were 4 samples that met the wastewater quality standards and there was one sample that did not meet the wastewater quality standards, namely sample code 55/LC/01/23.
