Abstract

Microbial resistance has become a threat that causes thousands of deaths yearly; therefore, efforts are required to address this problem. One of the promising methods used to inhibit bacterial growth is photocatalyst technology. In this research, CaTiO3 compounds was synthesized using the molten salt method and tested for antibacterial activity in both UV-unexposed and UV-exposed conditions on Staphylococcus aureus bacteria. The diffractogram showed that the CaTiO3 compound was successfully synthesized without impurities that indicated by the characteristic peaks at 2θ (o) = 23.29; 33.18; 47.52; 59.33; 69.48; 79.17. The micrograph results showed that the CaTiO3 compound had a regular polyhedral shape and was agglomerated with particle sizes in the 0.2941 ± 0.0144 µm range. The UV-Vis DRS spectra showed that the CaTiO3 compound had a bandgap energy of 3.48 eV (315 nm). In the antibacterial activity test results under UV irradiation, the growth of Staphylococcus aureus decreased by 3.95, 0.91, and 1.45 CFU/mL.
