Indonesia, as a tropical country, possesses substantial potential for the development and utilization of essential oils, particularly those derived from lemongrass (Cymbopogon citratus) and clove flowers (Syzygium aromaticum).

In contrast, clove essential oil is predominantly composed of eugenol, a compound recognized for its strong antibacterial and antioxidant properties. This study aimed to evaluate the effect of clove essential oil addition on the antibacterial and antioxidant activities of lemongrass essential oil.
