N2 - Cellulose produced from bacteria is a biopolymer that having high strength, purity and permeability so that it can be applied in various fields. The study aims to observe the morphology and structure of BC after being treated by a chemical reagent. The study was conducted using a BC pellicle that was produced from an extract of pineapple peel waste after being fermented for 10 days by Acetobacter xylinum. BC pellicle was treated by a chemical reagent solution (BmimCl, H2O2, and NaOH) by a concentration of 5%. BC pellicle was immersed in chemical reagent at 80 °C for 2 hours then dried in an oven for 6 hours at 70°C. The morphology observation was conducted under the Scanning Electron Microscope, and the structure was analysed using XRD apparatus. The results indicate that diffractogram of BC film after chemical pretreatment, the crystal size of BC film reduce from 10.01 nm (without treatment) to 3.67 nm, 3.62 nm, and 3.68 nm for pretreatment fo NaOH, H2O2, and BmimCl, respectively. The highest crystallinity of BC film was obtained by pretreatment using H2O2 with a crystallinity of 76.83%. The morphology of BC film indicated that pretreatment using NaOH, H2O2, and BmimCl cause peel of BC nanofiber so that the surface of BC film looks rougher and more porous.
