Testing the Antibacterial Activity of Tabasco Pepper Leaf Ethanol Extract Grown in Coastal Area on Staphylococcus aureus and Escherichia coli

Abstract

Tabasco pepper(Capsicum frutescens) leafis one of traditional medicines that people believe is able to treat various diseases.In this study, the antibacterial activity of the ethanol extract of tabasco pepper(Capsicum frutescens) leaf was tested against Staphylococcus aureus and Escherichia coli using agar diffusion method.This study is an experimental study using a population variation of gram-positive and gram-negative bacteria. Variations in extract concentrations used were 5%, 10%, 20%, and 30% concentrations as well as positive control (Ciprofloxacin) and negative control (DMSO 10%). The test results showed that the ethanol extract of tabasco pepper(Capsicum frutescens) leaf gave antibacterial activity at a concentration of 20% and 30% against Staphylococcus aureus and Escherichia coli with resistance diameters of 6 mm and 9.4 mm, respectively. The activity equivalence value of tabasco pepper(Capsicum frutescens) leaf ethanol extract against Ciprofloxacin was 22.6 mm - 19.5 mm for Staphylococcus aureus and 20.4 mm - 22.3 mm for Escherichia coli.
