Abstract

During each day of harvest, wasted banana stems are obtained in large quantities. These stems are composed mainly of 74.37% cellulose which is a very important raw material. This study aims to isolate cellulose from banana stems using liquefaction, delignification and bleaching processes with a microwave  at power variations of 450, 600 and 800 W.  The results showed that the highest cellulose content of 86.43% was obtained at 800 W for 14 minutes. Meanwhile, the fourier-transform infrared spectroscopy (FTIR) analysis result did not show a peak at wavenumber 1519 cm-1 which is the specific peak for lignin but showed a peak for cellulose at wavenumber 898 cm-1. Furthermore, XRD analysis of crystallinity showed a typical diffraction peak of cellulose at 22.5o with a degree of crystallinity of 56.8% while, morphological analysis with SEM showed that the sizes of the cellulose fibers produced varied, ranging from 5 to hundreds of micrometers and visible fibrillary fibers
