Modification Charcoal Eceng Gondok (EichorniaCrassipes) Toward Chitosan-Epichlorohydrin and its Solubility Test

Abstract

.The research has been conducted entitled "Modification of EcengGondok (EichorniaCrassipes) to Chitosan-Epichlorohydrin". The aim of this research is to determine the solubility test of water hyacinth composite on chitosan-epichlorohydrin. This research begins with sample preparation covering the manufacture of eceng gondok and charcoal activation and testing the quality of activated charcoal of Eceng Gondok. After that, it is continued by making the composite through the initial stages of chitosan charcoal production and chitosan modified chitosan test and chitosan-epichlorohydrin modified chitosan test. The result of the research shows that 3 standard of active charcoal quality test fulfill SNI requirement except fly content. And chitosan charcoal solubility test showed that the solubility level of charcoal: the lowest chitosan was found on charcoal ratio: chitosan 5:7. While chitosan-epichlorohydrin-modified chitosan test showed that the lowest solubility rate occurred at a concentration of 1% epichlorohydrin.
