Porang starch bioplastic (Amorphophallus oncophyllus Prain) and chitosan with sorbitol plasticizer were made by heating the solution on a hotplate at 80℃, and drying in an oven at 60℃. Results Characteristics of porang starch bioplastic obtained thickness 0.144-0.212 mm, water absorption 58.33%-87.75%, density 1.256-2.942 g/cm3, highest tensile strength 2.567 Mpa, highest elongation 52.499%, biodegradation in the first week 32.85%-39.21%. SEM characterization of bioplastics showed that the surface was uneven and no cracks formed. The FTIR spectrum showed no change in the wave number of the spectrum of porang starch, chitosan, and sorbitol with OH, CO, and NH functional groups. This shows that the resulting bioplastic only interacts physically. [ABSTRACT FROM AUTHOR] |
