Research has been carried out on the characterization of the physical and biodegradable properties of areca nut nanofiber composites with a polymer matrix with the aim of understanding the physical factors that affect the mechanical strength and biodegradability of the composite material. The method of making nanocellulose from betel nut is fiber refining, bleaching, and delignification which are then homogenized. The composite was made by dry mixing method between nanocellulose and polymer. The tests carried out are in the form of physical properties tests (tensile strength, strain, modulus of elasticity, and biodegradation tests) and tests of electrical properties (conductivity). The characterizations used are PSA (Particle Size Analyzer), FTIR (Fourier Transform Infrared), and transparency test. The results obtained in the form of the highest tensile strength, strain, and modulus of elasticity were 11.23 MPa, 52.17%, and 21.252 MPa. The average value of biodegradation is 4.0008033%/day. The highest conductivity value is 3.2 x 10-4 S/cm. The results of PSA characterization showed that the nanofibers had a particle diameter of 79-187 nm. FTIR characterization shows that there are C=O functional groups and C-O on the plastic film is a hydrophilic group which indicates that the plastic film can be degraded.
