Abstract

This study aims to determine the absorption of water detergent waste using water spinach (ipomoea aquatica). This experimental study used a randomized block design. Water samples were planted with water plants according to the research design. Detergent concentrations were observed using the MBAS (Methylene Blue Active Substance) method. The results showed that water spinach was able to reduce the detergent concentration and improve the concentration of water quality parameters (DO, BOD, and COD). After the treatment of water kangkong, the ability to absorb detergent was seen with a decrease in detergent levels until day 28 of 54.17%. The highest detergent absorption on days 7 and 14.

Highlights

Detergent is a synthetic cleaning agent that is used by industry and households
Chemical Oxygen Demand (COD) is the amount of oxygen in ppm or mg/l needed under special conditions to chemically decompose organic matter, (Devi Ramayanti, 2019)
The COD value in the water sample on the first day was quite high, namely 40.7 mg/l, which was above the class II water quality standard

Summary

Introduction

Detergent is a synthetic cleaning agent that is used by industry and households. Detergents contain petrochemical ingredients or other synthetic surfactants. The advantage of detergent is that it has good washing power and is not affected by water hardness. Hard water is water that contains mineral ions such as Ca, Fe, Mg, and Mn. The weakness of detergents is that they contain active substances that are difficult to degrade by microorganisms. The active substances contained in detergents are surfactants, builders, pH, buffers, and other addictive substances (Yangzin, 2008). The largest composition of detergents is surfactants, namely 15% to 40% (Yangxin, 2008). The surfactants in detergents consist of anionic, cationic, and nonionic surfactants. A good surfactant for cleaning is anionic surfactant.
