    Abstract

    THE INHIBITION CHITOSAN/Ag COMPOSITE WITH SiO2 LAYER ON THE COTTON FOR BACTERIAL ACTIVITY OF Escherichia coli DESWITA ARIATIANTI Department of Chemistry, Faculty of Mathematic and Sciences Sebelas Maret University ABSTRACT The study of additional antibacterial characteristic chitosan/Ag composite with SiO2 on the cotton was has been conducted. The purpose of this research had studied the time of adsorpsion Ag metal by chitosan, the influence of SiO2 layer and chitosan/Ag composite on the cotton, and inhibition of chitosan/Ag composite with the SiO2 on the cotton before and after laundering for the growth activity of E.coli. Adsorption of the Ag metal by chitosan was conducted with variation of the shaker time. SiO2 layer and chitosan/Ag composite on the cotton could be analyzed from XRD, SEM and stiffness tester. The inhibition of chitosan/Ag composite with SiO2 on the cotton before and after the laundering for the growth activity of E.coli with shake flash method and turbidimetry. The results showed that longer time of adsorption so more Ag metal adsorped by chitosan. The optimum time of adsorption was at five hours (to at 5 hours). SiO2 layer made cotton not stiff and chitosan/Ag composite on the cotton made cotton stiff. The optimum consentration of chitosan/Ag composite was 0.1 % (b/v) as bacterial agent before and after laundering. And inhibition of chitosan/Ag composit with SiO2 before laundering was higher than after laundering for the growth activity of E.coli. Key word : SiO2, cotton, chitosan/Ag, inhibition, E.coli
