Abstract
Solid Polymer Electrolyte (SPE) telah dibuat dengan metode solution casting. SPE yang terdiri dari polimer host PVA dicampur dengan biopolimer kitosan (CS), NaClO4 sebagai garam, serta SiO2 yang disintesis dari abu ampas tebu sebagai filler untuk meningkatkan konduktivitas ion dari sistem elektrolit. Penggunaan biopolimer kitosan dan filler SiO2 dari abu ampas tebu untuk mendapatkan SPE yang ramah lingkungan, mengurangi permasalahan limbah, dan biaya produksi yang lebih murah. Penggunaan garam NaClO4 sebagai sumber ion natrium dan penambahan filler dilakukan agar kristalinitas polimer berkurang dan diperoleh konduktivitas ion yang tinggi. Pada penelitian ini, dihasilkan film SPE yang tipis dan tidak mudah robek. Hasil uji XRD menunjukkan kristalinitas yang menurun setelah penambahan garam NaClO4 dan filler SiO2. Spektra FTIR menunjukkan NaClO4 berikatan dengan polimer dan SiO2 bertindak sebagai filler saja. Dari hasil karakterisasi disimpulkan penambahan garam NaClO4 dan SiO2 sebagai filler dapat meningkatkan konduktivitas ion dari sistem elektrolit. Konduktivitas ion maksimum sebesar 3,00 × 10-4 S cm-1 pada suhu ruang yang diperoleh dari rasio PVA:CS:NaClO4 (3:2:4) dan SiO2 sebanyak 5%.

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 increase the 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 conductivity is 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.
