Abstract
Attarasa Litsea cubeba (Lour.) Press. is a traditional plant that is widely used as an antidiarrheal, a cure for skin diseases and antiseptics. This plant contains compounds from tannins, flavonoids, alkaloids and glycosides. The purpose of this study was to determine the antibacterial activity and concentration of what is the antibacterial activity of ethanol extract attarasa Litsea cubeba (Lour.) Press. can inhibit the bacteria Staphylococcus aureus and Escherichia coli.
Search for the fruits of Litsea cubeba (Lour.) Press. with the maceration method using 70% ethanol solvent, extract concentrations used are 50%, 25% and 12.5% and testing for antibacterial activity with bacteria Staphylococcus aureus and Escherichia coli using a diffusion method to measure the diameter of the inhibition area.
The results showed that antibacterial activity test on attarasa extract on Staphylococcus aureus bacteria at a concentration of 50% had inhibition of 15.4 ± .07mm, 25% inhibition of 14.8 ± .70 mm, and 12.5% of inhibition 15 , 4 ± .80mm and in Escherichia coli bacteria with a concentration of 50% inhibition of 13.1 ± .61mm, 25% inhibition 13.4 ± .57mm and 12.5% inhibition 12.3 ± .75mm .
In this study it was concluded that the activity and concentration test showed that the ethanol extract of attarasa fruit had antibacterial activity against the bacteria Staphylococcus aureus and Escherichia coli and that most effectively killed the staphylococcus aureus bacteria at a concentration of 50 mg / ml with a diameter of 15.4 mg/ml .
