    Abstract

    Achatina fullica’s shells are solid waste which can be used as raw material which is cultivated to chitin and chitosan. The aim of this experiment is to get optimum condition of cultivation Achatina fullica’s shells to chitin and chitosan on condition’s variation of demineralization and deacetylation. Synthesis of adsorbent by crosslink and microencapsulation modification produce modified chitosan CTS, PEI-EPI-EGDE-CTS, microcapsules PSF-PEI-EPI-EGDE-CTS and PSF-EGDE-CTS had been done. The microcapsules were prepared through three step i.e. the formation of gel beads (CTS), crosslinked CTS with EGDE (EGDE-CTS) and microencapsulation EGDE-CTS with Polysulfone (PSF-EGDE-CTS). Characterization of product using FTIR and SEM. PSF-EGDE-CTS used for adsorption of Procion Red MX 8B dye. Adsorption of Procion Red MX 8B dye by modified chitosan was done by variation of pH and contact time in order to determine optimum condition of adsorption. Variation of concentration was done to determine isotherm adsorption type that occurred during the adsorption process. The types of the adsorption isotherm were analyzed by Langmuir and Freundlich isotherm. Adsorption and desorption of Procion Red MX 8B dye by PSF-EGDE-CTS were measured in the optimum condition. The results showed that optimum condition for chitin isolation from Achatina fullica shells for demineralization process could be obtain in the concentration of HCl of 1.25 M and the optimum of time of demineralization is 6 hours with water content, ash content and percentage of yield were 0.995 ± 0.007 %; 14.925 ± 0.106 % and 15.940 %. Optimum condition of deacetylation could be obtain in the concentration of NaOH of 30 % with degree of deacetylation, molecular weight and degree of polymerization values of chitosan were 84.67 %; 2,086 g/mol and 13. The yield of Microcapsules PSF-EGDE-CTS was 94,792 wt %. The optimum condition of Procion Red MX 8B dye adsorption by CTS at pH 7 and contact time at 42 hours. The adsorption capacity of CTS was 56,220 mg/g. The type of Procion Red MX 8B dye adsorption by CTS, EGDE-CTS and PSF-EGDE-CTS that occured was chemical adsorption.
