A gas sensor is a renewed interest of research which has been developed to make a device that can be detected the harmful gases and applied in the several fields of industries. In this paper, we report the modified of gas sensor based thick film ceramic LaFeO3/Fe2O3 by added calcium and zinc co-doping prepared by screen-printed technique. In this work, yarosite mineral was utilized as Fe2O3 precursor. It aims to take the advantages of abundance natural resources in Indonesia to save a cost in gas sensor fabrication. Then, x-ray diffraction (XRD), scanning electron microscopy (SEM) and electrical properties characterization were applied to the calcium and zinc co-doped LaFeO3/Fe2O3-based thick film ceramics. It is obtained that the crystal structures were cubic with crystallite size at about 51.19 nm and 48.17 nm. SEM images informed that calcium and zinc co-doped caused the larger pores of LaF eO3/F e2O3. It indicates that the gas sensors shows a response to the ethanol gases. Lastly, calcium and zinc co-doped can be a potential candidate to enhance the highly performance of gas sensors. Moreover, yarosite mineral also can be used to develop the future perspectives of ethanol gas sensors. © 2021. All Rights Reserved.
