Abstract

Research has been carried out on the synthesis and characterization of Mg - Chitosan complex ions from shrimp shells using crosslink method. Chitosan isolation was made in four stages, namely deproteination, demineralization, depigmentation and deacetylation. The maximum degree of deacetylation (DD) of chitosan is 89%. Based on XRD and FTIR data, chitosan obtained is in the form of amorphous and there are typical wave number of chitosan, namely 3444.91 cm-1 and 1658.4 cm-1 associated to O-H, N-H dan C=O.

Abstract

A research about Asaron oil purification produced over Stahl distillation has been done. This research was conducted by distillation of Genoak’s roots, rhizomes and leaves whilst the purification was carried out through reduced pressure distillation. A yellowish oil was yield respectively 1,83 gram from the roots and rhizomes and 1,26 gram from leaves which then was revealed as 90,49% pure of asaron confirmed using GC-MS, 1H-NMR and FT-IR analysis.
