Analisis Kadar Total Suspended Solid (TSS) pada Air Limbah Domestik secara Gravimetri

Abstrak

Water plays a crucial role in human life and is used in various activities; however, pollution from domestic, industrial, and agricultural waste can degrade its quality. Domestic waste, which originates from bathroom, kitchen, and laundry discharges, generally contains organic pollutants, bacteria, viruses, detergents, and high nutrients that can lead to eutrophication and an increase in Total Suspended Solids (TSS). TSS consists of suspended solids such as sludge, fine sand, and microorganisms that increase turbidity, hinder light penetration, and disrupt aquatic biota. Analysis of three samples of domestic wastewater showed TSS levels of 29.050–29.075 mg/L, 22.080–23.260 mg/L, and 28.570–28.650 mg/L, which still meet the quality standards according to the Minister of Environment and Forestry Regulation No. P.68/Menlhk-Setjen/2016. The percentage of Relative Percent Deviation (RPD) for all samples also complies with SNI 6989.3:2019 (≤15%).
