The study of preparation and characterization of microcrystalline cellulose from the Lembang / narrowleaf cattail (Typha angustifolia L.) has been carried out. Alkalinization was done to remove lignin and hemicellulose compounds. The bleaching process was done by adding 4 M HCl at 65 oC for 3 hours and then sonicated for 10 minutes. The cellulose yield obtained was 32.2%. The Fourier Transform Infrared (FTIR) spectra indicated the appearance of some specific functional groups (O-H, -C-H, =C-H and C-O, and C-O-C). Scanning Electron Microscope (SEM) showed that the structure of cellulose is a long crystalline with a diameter of 3.1 µm. Thermogravimetric analysis (TGA) showed decomposition at higher temperatures of 349.13, 366.66 and 353.24 oC for cellulose after hydrolysis, cellulose before hydrolysis, and TaL powder. Crystalline index and crystalline size of microcrystalline cellulose analyzed by X-Ray Diffraction (XRD) were 71.1% and 2.4 nm, respectively.
