Abstract

Abstract: Abstrak. This research identified the effect of additional polyethylene glycol (PEG) in bacterial cellulose made from pineapple peel waste. The produced pellicles were soaked in PEG solution with 0%, 1%, 2.5%, and 5%. Then, they were homogenised using an ultrasonic homogeniser for 15 minutes before dried using the freeze-drying method. The functional groups were observed using FTIR. The functional groups showed the presence of cellulose I and cellulose II at 439.08 cm −1, 2895.15 cm −1, 1963.53 cm −1 1633.71 cm −1, 1315.45 cm −1, 839.03 cm −1 wavenumbers. Additional PEG caused an increase of the C-H bond at 1963.53 cm −1 wave number.
