Abstract

Startfruit (Averrhoa bilimbi L.) is one the kind of plant that is widely used as a traditional herbal medicineto overcome various diseases i.e. diabetes mellitus, cough, rheumatism, thrush, diabetes, toothache, acne, etc. The secondary metabolites of the starfruit leaves contain flavonoids and tannins, whereby these activecompounds can be used as an antibacterial. This study aimed to determine the inhibiting power of starfruit leaf ethanol extract against Staphylococcus epidermidis at concentrations of 25%, 50%, 75%, and 100%. The research was conducted at the  AKAFARMA Laboratory and the Chemistry Laboratory , Faculty of Teacher Training and Education, Syiah Kuala University from June to July 2020. The research method was laboratory experimental using the disk diffusion method. The population of starfruit leaves was obtained from Lhokseumawe  using a purposive sampling technique. Ethanol extract of starfruit leaves with concentrations of 25%, 50%, 75%, and 100%. The diameter of the inhibition zone of the ethanol extract  from the starfruit leaves at  concentrations of 100%, 75%, 50%, and 25% were 15 mm, 12 mm, 11 mm and 10 mm, respectively. It can be concluded that  ethanol extract of starfruit leaves can inhibit the growth  of  Staphylococcus  epidermidis  with  a  maximum inhibitory concentration  of  100%,  which is classified  as a strong category.
