Pemanfaatan Limbah Udang (Kitosan) Sebagai Koagulan Alami Dalam Penurunan Parameter Air Gambut

Abstract

Rantau Karya Village is a coastal area of Tanjung Jabung Timur with a shallow peat depth of 1-2 meters and a medium depth of 3-4 meters that has peat water as a source of community life water and has potential marine resources such as shrimp. Shrimp waste that is not utilized by the community, as absorbance material in peat water treatment. This research conducted an experiment utilizing shrimp waste which, was transformed into chitosan as a natural coagulant in the process of peat water treatment. The method used is an experimental method and laboratory scale. The purpose of this study is to utilize shrimp waste into chitosan as a natural coagulant in reducing peat water parameter values and determining the optimum dose of chitosan in reducing peat water concentration. The results showed that chitosan shrimp waste could be used as a natural coagulant in the process of peat water treatment by raising the pH parameter values in peat water, reducing the color, iron, manganese, organic substances. The optimum dose obtained was a pH parameter of 400 mg / l with a percentage increase of 75%, color 100 mg / l with a decrease of 49.52%, iron 500 mg / l percentage of 85.44%, manganese 100 mg / l 49.52% and organic matter 100 mg / l percentage 73.49%.
