Abstract
Fiber membranes of Polyvinyl Alcohol (PVA)/Shell extract of melinjo (SEM) have been successfully synthesized using electrospinning method. The synthesis begins by making a precursor solution between a mixture of SEM solution and PVA solution. The SEM solution was made at a concentration of 10% using an ethanol mixture with water while the PVA solution was made at a concentration of 20% with a water solvent. The precursor solution ware made by mixing PVA solutions and SEM solution at several mass ratio; 10:0, 10:1, 10:3, and 10:5, and then synthesized into fiber using electrospinning method. Characterization of digital microscope was used to see morphology and diameter of the fibers produced. Likewise, the wettability properties of fiber membrane was determined using contact angle meter. The results showed that as the weight fraction of SEM increased, diameter of fibers changes. Subsequently, the wettability properties of fiber membranes changed as the changing of weight fraction of SEM.
