Chitosan is one of the natural polymers that can be used as material for nanofiber. Nanofiber made from chitosan alone could not produce a good nanofiber characteristic. Chitosan has to be mixed with other synthetic polymers such as polyvinyl alcohol (PVA). This research is carried out to study the characteristics of nanofiber made from swimming crab shell chitosan (DD of 89.06%)-PVA composite using electrospinning method. The chitosan-polyvinyl alcohol (chitosan-PVA) ratios were 1:9, 2:8, 3:7, and 4:6 (v/v). The parameters observed were the characteristics of chitosan (degree of deacetylation, moisture, ash, N total, viscosity, and functional group analysis using FTIR), and nanofiber characteristics (viscosity, morphological structure using scanning electron microscopy-SEM, and functional group analysis using FTIR). The results revealed that the structure of nanofibers produced still showed several beads. Addition of chitosan in the solution produced more beads in the nanofiber. The higher amount of PVA in the solution increased the viscosity of the solution of chitosan-PVA. FTIR data demonstrated a good intermolecular interaction between PVA and chitosan possibly due to hydrogen bonds.
