This was an experimental study on the antibiotic activity of Zingiber officinale (Ginger) and Curcuma longa (Turmeric) rhizomes was performed using ethanolic extraction. Different concentrations were prepared by diluting extract with DMSO to provide a 25%, 50%, 75%, and 100% concentration. It was then tested against staphylococcus aureus using the disk diffusion method. The study showed that Zingiber officinale (Ginger) and Curcuma longa (turmeric) rhizomes crude extract expressed no inhibitory potential on staphylococcus aureus due to the absence of "clearing" around the disks impregnated with the crude rhizome extracts. The findings suggested that the absence of zone of inhibition did not qualify the phytochemical compounds present in Zingiber officinale (Ginger) and Curcuma longa (Turmeric) rhizomes as an effective antibiotic agent to S. aureus. The researchers recommended that samples should be blended very finely to maximize surface are, sue different solvent in extracting the active ingredient, increase the volume of extract that is pregnated on the disc, use other part of the plants such as leaves or flowers, and test the extract on other organisms.
