This research successfully fabricated scaffolds with hydroxyapatite (HA) from limestone and with HA coating using the gas foaming method. HA coating uses the addition of cinnamon oil in HA from limestone and impacts the scaffold’s antibacterial properties. Scaffold fabrication uses the gas foaming method with a drying time of 30 minutes and 0.9 grams of HA. The fabricated scaffold is then characterized using an X-ray diffractometer (XRD), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscopy (SEM). Then, the antibacterial analysis of scaffolds using the diffusion method. Scaffolds from HA coating have smaller crystal sizes, fewer agglomerations, smaller particle sizes, and a more even distribution and size of pores. Scaffolds with HA coating have higher porosity than scaffolds with HA only. HA coating shows that adding cinnamon oil as an antibacterial agent can inhibit strong bacteria for S. aureus bacteria with an inhibition zone size of 11 mm. © 2024, Hanyang University.
