Morphology and Crystallinity Study of Sago Starch-Based Degradable Plastic with Chitosan and Calcium Carbonate as Additives
To reduce the consumption of synthetic polymers, researchers have studied the use of carbohydrates, lipids, proteins and composites to generate biodegradable plastic. In this study, degradable plastic from sago starch modified with prepolymer polyurethane synthesized from diphenylmethylene dii...

| description | To reduce the consumption of synthetic polymers, researchers have studied the
use of carbohydrates, lipids, proteins and composites to generate biodegradable plastic. In
this study, degradable plastic from sago starch modified with prepolymer polyurethane
synthesized from diphenylmethylene diisocyanates and polyol with the addition of chitosan
as additive and polypropylene or polyethylene as matrix was produced. The research method
conducted were consisting of several stages, preparation of thermoplastic starch, blending
thermoplastic starch with polypropylene or polyethylene, synthesis of degradable plastic and
irradiation process. Thermoplastic starch was characterized using Scanning Electron
Microscopy-Energy Dispersive X-Ray (SEM-EDX) and X-Ray Diffraction (XRD). SEM-EDX to study surface morphology, meanwhile XRD to determine the crystallinity of
thermoplastic starch. The SEM analysis of 5000x magnification showed the presence of
many material elements in the thermoplastic starch matrix that are visible on the entire
surface of the plastic. The results of EDX analysis revealed the presence of chemical
elements such as carbon, oxygen, magnesium, calcium, titanium, palladium, gold, and
carbon dioxide. These elements came from the thermoplastic starch made from sago which
contains magnesium (iron), calcium and the main additive CaCO3. From the XRD analysis
results, it can be shown that thermoplastic starch was amorphous and crystalline. XRD
analysis of thermoplastic starch has a low crystallinity value at 26.85140
