The Effect of Chitosan Addition on Characteristics of Biodegradable Plastic from Waste of Nata de Coco using Inversion Phase

Abstract

Exploration of biodegradable plastic material will solve pollution problem. The side product of nata de coco is potential to be proceed as biodegradable plastic due to its cellulose content, up to 42.57%. This research meant to learned the effect of chitosan addition for the making of biodegradable plastic from waste of nata de coco. The inversion phase was used in this study to produce bioplastics then several physical tests, FTIR, and biodegradability examination conducted to evaluate its mechanical properties. This study used complete randomized design combined with factorial design. The bioplastic product was manufactured using cellulose of nata de coco in three variation, 2.00; 2.50; 3.00 gram combined with 3 variation of chitosan, 2.50; 3.00; 3.50 gram. Statistical analysis of all quantitative data was conducted by using Multiple analysis of variance (MANOVA) (p<0.05) using the SPSS-25 program. Based on the result of the research, the value of mechanical properties there is an optimal tensile strength of bioplastics was 4,22 Mpa and elongation was 3,28%. An optimal water resistance value of bioplastics was 70,93%. FTIR result indicate that synthesized bioplastics have a wavelength value similar to the constituent raw material and biodegradability result obtained 80 - 100 %.
