The development of energy storage devices encourage sustainability of research on basic materials of supercapacitor technology. SrTiO3 is oxide metal called as titanate alkali metal ATiO3 (A = Ba, Sr, Ca). This material shows an excellent dielectric constant, thus expected to be a potential as raw material of supercapacitor. In this work, boron was used as a dopant on SrTiO3 system. Synthesis SrTi1-xBxO3 was carried out using solid-state reaction method followed by sintering process in various molar ratio. By introducing boron, it was expected to modify its local structure and enhance the electrical properties. The microstructure of SrTi1-xBxO3 compound was identified by X-ray Diffraction with Cu-Ka. Based on XRD data analysis, a single phase of SrTi1-xBxO3 material was confirmed with a slight change in lattice parameters. Furthermore, SEM-EDX was used to observe the morphology and elemental composition of SrTi1-xBxO3. For investigating the electrical conductivity, I-V meter measurement was applied by inducing various temperature. Higher boron fraction in the compound raised the electrical conductivity, thus it will be performed as supercapacitor material.
