Analisis Kadar Padatan Tersuspensi Total (TSS) Dan Logam Krom Total (Cr) Pada Limbah Tekstil Di Dinas Lingkungan Hidup Sukoharjo

Abstract

Textile waste is one of the most common liquid wastes and has the potential to pollute the environment. This is due to the high level of water pollution and the degree of water contamination indicating the presence of TSS solids which increase the density of waste and textile waste water also contains very complex pollutants such as metal Chrome (Cr). Based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Quality standards for wastewater for businesses and / or activities of the textile industry for total suspended solids (TSS) parameters of 50mg / L and for total chromium (Cr) metal parameters of 1.0 mg / L To overcome this problem, it is necessary to analyze TSS levels and total chromium metal whether it is in accordance with the textile industry wastewater quality standards. Analysis of TSS levels can be done using gravimetric methods and analysis of total chromium metal levels using the AAS instrument. From the analysis, it was found that the total TSS and chromium metal levels in the waste were still below the standard threshold for wastewater quality, namely 20 mg / L for TSS levels and total chromium metal at 0.112 mg / L.
