|dc.description.abstract||Alpha cellulose which was isolated from cellulose of fiber empty fruit bunch palm oil
was hidrolized with hydrochloric acid (2,5N) at 80oC to produce microcrystalline cellulose
(MCC). Microcrystalline cellulose is an important additional ingredient in the pharmaceutical,
food, cosmetics, and structural composites. In this study, MCC, alpha cellulose, and cellulose
were characterized and thereafter were compared. Characterizations were made using some
equipment such as x-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron
microscopy (SEM) and thermogravimetry analyzer (TGA). X-ray diffraction and infrared
spectroscopy were studied to determine crystallinity and molecular structure of MCC, where
scanning electron microscopy images were conducted for information about morfology of MCC.
Meanwhile, thermal resistance of MCC was determined using thermogravimetry analyzer
(TGA). From XRD and FTIR, the obtained results showed that the crystalline part was traced on
MCC, where the –OH and C-O groups tended to reduced as alpha cellulose has changed to MCC.
From SEM the image showed the reduction of particle size of MCC, while the thermal resistance
of MCC was found lower as compared with cellulose and alpha cellulose as well, which was
attributed to the lower molecular weight of MCC.||id
