Pengaruh Selulosa Nanokristal dari Serat Buah Kelapa Sawit sebagai Pengisi dan Kalium Klorida sebagai Agen Pendispersi Terhadap Sifat Fisik Bioplastik Berbasis Pati Biji Alpukat (Persea americana)

This study aims to determine the effect of nanocrystalline cellulose and potassium chloride (KCl) bioplastics from avocado seed starch glycerol as plasticizer. In this study, nanocrystal obtained palm fruit fiber was hydrolyzed using sulfuric acid (H2SO4) at a concentration 50%. The used in extraction process. On producing bioplastic, casting method with addition filler 1%, 2%, 3%, 4% (%w), KCl dispersing agent 0%, 3% plasticizer by 30 (%w). Based on density test, optimum value 2% around 0.041 gram/cm3. best water absorption values were 57.1% 53.8% which 1% KCl. Scanning Electron Microscope test results showed uniformly distributed granules filling surface bioplastic. dispersion give good impact.
