Solid Polymer Electrolyte (SPE) has been made by the solution casting method. SPE consists of PVA as host polymer mixed with chitosan (CS) biopolymer, NaClO4 as salt, and SiO2 synthesized from bagasse ash as a filler to increasethe ionic conductivity of the electrolyte system. Using chitosan biopolymer and SiO2 filler from bagasse ash to obtain environmentally friendly SPE, reduce waste problems, and lower production costs. The use of NaClO4 salt as a source of sodium ions and the addition of fillers is done so that the crystallinity of the polymer is reduced and high ionic conductivityis obtained. In this study, a thin SPE film was produced that was not easily torn. XRD test results showed a decreased crystallinity after the addition of NaClO4 salt and SiO2 filler. The FTIR spectra showed that NaClO4 binds to the polymer and SiO2 acts as a filler only. From the characterization results, it was concluded that the addition of NaClO4 and SiO2 salts as fillers could increase the ionic conductivity of the electrolyte system. The maximum ionic conductivity of 3.00×10-4 S cm-1 at room temperature is obtained from the ratio of PVA:CS:NaClO4 (3:2:4) and 5% SiO2.
