| dc.description.abstract | Bacterial cellulose is be used as membrane filtration. This research was conducted to produce bacterial cellulose by using various concentrations of watermelon rind in the fermentation medium (30%, 40%, 50%, 60%, and 70%). The bacterial cellulose were produced then characterized for their morphology, functional groups, and selectivity analysis. Our result showed that the surface of the bacterial cellulose membrane and formed interwoven structure of microfibrils cellulose. The Cross-sectional observations of cellulose membrane showed many layers of bacterial cellulose with irregular pore and the layer had their own interbond. The FTIR spectra showed that the membrane has functional groups of C-H, O-H, C-O, C-O-C, and Pyranose which acted as specific functional groups of bacterial cellulose. These findings indicated that bacterial cellulose membrane of 70% watermelon rind concentration had the optimum selectivity value in 72.43% rejection. | en_US |
