Pengaruh Komposisi Kitosan Terhadap Sifat Fisis Dan Biodegradable Film Komposit Nanoserat Pinang Dengan Castor Oil Sebagai Plasticizer

Research has been carried out on the effect of chitosan composition physical and biodegradable properties areca nut nanofiber composite films with castor oil as a plasticizer. Samples were made using solution casting method. The variations used 0 g, 0.56 0.7 0.84 1.4 g one sample starch variation chitosan. samples tested thickness test, FTIR test FESEM test. Mechanical tests include tensile strength, elongation, elasticity, biodegradation tests. characterized Particle Size Analyzer (PSA) to determine size nanofibers, Field Emission Scanning Electron Microscope (FESEM) morphology Fourier Transform Infrared (FTIR) functional groups. PSA results showed that nanofibers had diameter (79-187) nm. characterization obtained shape hollow plastic surface. indicate presence C=O group C-O is hydrophilic which indicates capable being degraded. best strength in without value 20.04 MPa, elongation 138.56%, elasticity 198.66 MPa addition starch, average 0.25 mm. higher chitosan, thickness, plastics increase, while decreases
