Temperature and Mass Variations in the Utilization of Water Hyatong with and without Processing as an Adsorbent for Textile Dyes (Yellow) Y FG R

Every human activity produces liquid waste or solid waste or gas, small-scale waste does not cause problems but large-scale waste that will cause problems that can disrupt environmental balance, including liquid waste that can disrupt aquatic ecosystems both in rivers and at sea. The purpose of this study is to obtain the optimum conditions for absorption capacity against the influence of temperature and concentration as well as the absorption capacity of processed water hyacinth plants. Because in industries such as the woven fabric industry in the city of Palembang, it produces liquid waste in the form of residual water from soaking textile dyes which are sometimes discharged directly into residents’ waters or also discharged into rivers which ultimately has a negative impact on the surrounding environment which makes water that functions as the main source of daily life can be problematic because the water may have been contaminated by waste, therefore the purpose of this study can at least reduce water pollution in residents’ waters and even river water. The data collected comes from the dye analysis method based on the theory developed by Yassir (2011). The purpose of this study is to use textile dye Y FG R (yellow) and the testing will be carried out every 0, 1 and 7 hours for a maximum time with an HCL concentration of 0.5 with each sample of water hyacinth 2, 3, 4 grams as an absorbent material with the addition of temperature variables of 40 oC and 50 oC so as to obtain the results.
