Abstract

The presence of arsenic metal in water naturally due to its mobility causes the nature of water to become toxic and become a problem in the world. The purpose of this study was to determine the maximum adsorption capacity through the isotherm model and the rate of adsorption kinetics in the use of chitosan and coffee grounds as adsorbent in reducing the concentration of arsenic in industrial wastewater. The research method was carried out using experiments in the laboratory followed by quantitative data analysis to determine the isotherm model and adsorption kinetics. shows that the adsorption isotherm follows the Langmuir isotherm model with a correlation coefficient of 0.9972 with a maximum adsorption capacity of 2.063 mg.g-1 which indicates that chemical adsorption occurs in a mono layer with a homogeneous distribution of adsorption sites with constant adsorption energy and interactions between negligible metal arsenic (adsorbate) molecules. The study of arsenic adsorption kinetics using chitosan-activated carbon coffee grounds followed the Weber-Morris model/intra-particle diffusion with a correlation coefficient of 0.9920 with a diffusion rate of 76.512 g.mg-1.hour-1 which indicates that intra-particle diffusion is a rate step. limiting factor in the overall biosorption process. Keywords: Isotherm, Kinetics, Adsorption, Chitosan, Coffee Grounds

Abstract

Waste is still a serious problem in Indonesia. How to manage waste in the community environment refers to the end of pipe method (final approach). Waste management with the end of pipe method can be replaced in a new way, namely by managing waste earlier. Eco enzyme or eco enzyme in Indonesian is a solution of complex organic substances produced from the fermentation process of organic waste, sugars, and water. Waste processing with the Eco enzyme method uses the fermentation method (Bernadin, Desmintari, and Yuhanijaya 2017). This eco enzyme is made with the basic ingredients of kitchen waste which includes fruit and vegetable skins and then mixed with brown sugar (mollase) and water in a ratio of 3: 1: 10. In this study, there were five Eco Enzyme variables with different compositions, namely by using banana peel components, dragon fruit peels, potatoes, corn, and carrots. The results showed that the fermentation of eco enzyme solutions made from banana peels, dragon fruit peels, potatoes, corn, and carrots had acidic properties with a pH of 3.5, TDS 1460, and a moisture content of 93%. Visually, the resulting solution is brownish in color, the smell smells freshly typical of fermented aromas, and is produced by mama enzymes in eco enzymes, as well as the absence of contamination such as insects or other animals. Keywords: Waste, Eco Enzyme, Fermentation
