Abstract

The Clean water crisis still being problem that can't be resolved around trhe world, including in Indonesia. Indonesia having the biggest water source, it's the peat water. However, unfortunately we can't use peat water as a source of clean water because of the high concentrations of natural organic compounds and Fe, which makes the colour of peat water is brown and have a terrible smell. One of the ways to reduce high concentrations of organic compounds and Fe is the adsorption techniques. In this study, researchers made hydrogel utilizing Durian Rind waste. The result of FTIR analysis show that cellulose-based on durian rind has been successfully produced. the hydrogel that we made was able to expand (swelling ratio) of 857%. It means that the hydrogel is hydrophilic and capable of absorbing Fe2+ ions that pollute peat water. The measurement results of the degree of cross-linkage showed that the hydrogel could absorb Fe2+ ions was 25%. Thus, with hydrogel, it can be a great solution as a peat water purifier.
