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.
