<![CDATA[A study has been conducted on influences of various chitosan concentrationas coating and storage time to Vitamin C concentration of green grape (Vitis vinifera L.) by dipping method. This study aims to de-termine the difference of chitosan concentration to physical characteristics, weight loss and vitamin C concen-tration of green grape. Chitosan coating was conducted on 50 grams of green grape by dipping method at var-ious concentration of chitosan that is 0%, 0,5%, 1%, 1,5% and 2% (w / v), kept on variation of one, four and seven day storage time. Determination of vitamin C concentration of green grape was done by UV-Vis spec-trophotometer measured at 256 nm wavelength with regression equation y = 0,0344 x + 0,101 and r = 0,998. Based on statistical test showed that chitosan concentration of 1% (w / v) with 4 days storage time is the most optimum because the chitosan layer is able to close all green grape pores, so the process of anaerobic and CO2 respiration can be inhibited by chitosan solution.]]>

<![CDATA[The synthesis chitosan linked by methylene bridge-Schiff base of 4,4-diaminodiphenyl ether-vanillin (modified chitosan adsorbent) has been studied. The aims of this research were modification of chitosan with Schiff base of 4,4-diaminodiphenyl ether-vanillin and formaldehyde and its application as antibacterial agent after used as an adsorbent of Zn(II) ion. Characterization of modified chitosan adsorbent was conducted using FTIR spectroscopy. Process of adsorption were conducted at 0.15 g of modified chitosan adsorbent reacted by concentration of Zn(II) ion solution (pH 6, 150 mg/L, 50 mL), contact time at 150 min. and at room temperature (280C). Modified chitosan adsorbent after reacted by Zn(II) ion solution as antibacterial agent with paper disk method. The result showed that chitosan can be modified with Schiff base of 4,4-diaminodiphenyl ether-vanillin and formaldehyde to form chitosan linked methylene bridge and Schiff base of 4,4-diaminodiphenyl ether-vanillin. Antibacterial of chitosan and modified chitosan adsorbent were higher than modified chitosan adsorbent after reacted by Zn(II) ion. Keywords : modified chitosan, antibacterial agent]]>

Modified cellulose used as adsorbent for Cu(II) ion in aqueous solution. The aims of research were modification cellulose with 3-chloropropyltrimethoxysilane and 2-mercaptobenzhotiazole (MBT), characterization of the modified cellulose with FTIR, SEM and XRD and adsorption study between cellulose-MBT adsorbent with Cu(II) ion in aqueous solution. The adsorbent of cellulose-MBT was synthesized by reflux process. Adsorption study between cellulose-MBT adsorbent with Cu(II) ion was investigated based on influence of pH solution, interaction time and initial concentration of Cu(II) ion. The result showed that activated cellulose can be modified with MBT to become cellulose-MBT adsorbent. The functional group of –C=N appeared at wavenumber 1658 cm-1 attributed to functional group of -C=N- is Schiff base of MBT. Presence functional group of S-H at cellulose-MBT adsorbent was not detected. The surface morphology of cellulose-MBT adsorbent after being interacted with Cu(II) ion was different before being interacted with Cu(II) ion. The diffractogram of cellulose-MBT adsorbent has similarity with cellulose-MBT adsorbent-Cu(II) ion. The optimum adsorption of Cu(II) ion was observed at pH 7.0 and 150 min of interaction time. Percentage of Cu(II) ion was absorbed by cellulose-MBT adsorbent tended to be constant after Cu(II) ion concentration 100 ppm.]]>
