Abstract

The sasirangan fabric home industry produces wastewater through the hot and cold dyeing process. It is necessary to know the coloring process and wastewater parameter values to design good wastewater treatment. The purpose of the study was to compare the wastewater parameter values including pH, NH3-N, BOD5, COD, TSS, Oil/Fat, Color, Phenol, Temperature, H2S and Crom Total from Sasirangan Home Industry Wastewater at Hot and Cold Dyeing. This type of research is comparative research with static group comparison design. The sample is a portion of wastewater from home industries from in the province of South Kalimantan Indonesia, namely Banjarmasin City, Banjarbaru City, and Banjar Regency. The sampling technique used accidental sampling with a total of 20 samples consisting of 10 samples of the hot dyeing process and 10 samples of the cold dyeing process. Parameters that do not meet the standards in the hot dyeing process are pH, BOD5, COD, TSS, color, and phenol, while in the cold dyeing process are BOD5, COD, TSS, and color. Statistically, there is a significant difference in the parameter values of pH, TSS, color, phenol, and temperature in sasirangan cloth home industry wastewater between the two processes. The results of the research can be used for planning wastewater treatment for the Sasirangan home industry.

Abstract

Water is the main need of living things in the world. Water determines the sustainability of living things. Humans, animals, and plants depend on water for their survival. Therefore, water should always meet the standards that have been set. Wastewater from the home-based sasirangan industry has distinctive characteristics in the form of the color of wastewater that has not been managed properly. The purpose of this study was to determine the ability of alum to reduce the color of home-based sasirangan industry wastewater. The type of research is a true experiment, with the population being all home-based sasirangan industry wastewater in Atun Sasirangan Cempaka. The sample is part of the wastewater. The wastewater was put into 25 containers for 5 treatments of alum addition with concentrations of 40%, 80%, 160%, 240%, and 320%.  Each treatment was repeated 5 times. The results showed that the average value of wastewater color after treatment ranged from 140.5 to 179.2 Pt-Co. The lowest average value was in the treatment of adding alum with a concentration of 160%. It is concluded that alum is able to reduce the color of home-based sasirangan industry wastewater. It is recommended that the handling of wastewater color problems in the sasirangan fabric home industry use alum as a coagulant in the treatment method.
