In the present study, a novel solid biopolymer electrolyte (SBE) system is introduced by doping citric acid into alginate polymer. A sample of the alginate-citric acid SBE system was prepared via a solution casting technique. Using electrical impedance spectroscopy (EIS), the electrolytes of alginate-citric acid analyzed from 5 Hz to 1 MHz achieved the highest conductivity at 20 wt.% of 5.49 × 10 -7 S cm -1 . The temperature dependence of various citric acid amounts obeyed the Arrhenius rule with R 2~1 , where all SBE systems were thermally activated with increasing temperature. The dielectric studies of the alginate-citric acid SBE system showed non-Debye behavior based on data measured using complex permittivity (ε*) and complex electrical modulus (M*) at selected temperature, where no single relation was found in the new biopolymer electrolyte system. AbstractKarakterisasi Sifat-Sifat Listrik pada Alginat Berbasis Elektrolit Biopolimer Padat Baru yang Dimasukkan dengan Asam Sitrat. Di dalam studi kali ini, suatu sistem elektrolit biopolimer padat (SBE) baru telah diperkenalkan dengan mendoping asam sitrat ke dalam polimer alginat. Sampel sistem SBE alginat-asam sitrat dibuat melalui teknik pengecoran larutan. Dengan menggunakan Spektroskopi Impedansi Listrik (Electrical Impedance Spectroscopy (EIS)), elektrolit-elektrolit alginat-asam sitrat telah dianalisis dari 5 Hz sampai 1 MHz mencapai nilai konduktivitas tertinggi pada 20% berat sebesar 5,49 x 10-7 S cm-1. Ketergantungan temperatur berbagai komposisi asam sitrat terbukti mentaati aturan Arrhenius dengan R2~1 di mana semua sistem SBE diaktifkan secara termal ketika menaikkan temperatur. Studi-studi dielektrik tentang sistem SBE alginat-asam sitrat menunjukkan suatu perilaku non-debye berdasarkan pada data yang diukur dengan menggunakan permitivitas kompleks (ε*) dan modulus listrik kompleks (M*) pada temperatur yang dipilih di mana tidak ditemukan adanya hubungan tunggal di dalam sistem elektrolit biopolimer baru.
