Abstract

Bacterial infection of Escherichia coli (E. coli) as the cause of gastrointestinal disorders in humans has increased their prevalence. Treatment using natural ingredients can be a choice of therapy because of the minimal side effects. One of the rare plants believed by the community as an antibacterial is stinking vin’e known as the ‘leaf fart’. The purpose of this research is for knowing the activity of the ethanol extract of Paederia foetida L can affect the growth of E.coli. The serial diffusion disc method is being used as the antibacterial activity test. The concentration of this extract are 10%, 20%, 40%, 80%, 100% with positive control (ciprofloxacin) and negative control (aqua dest). The inhibition zone diameter characterized the effect of Extract on bacterial growth were 6.16 mm of the concentration 10%, 6.667 mm of the concentration 20%, 7.10 mm of the concentration 40 %, 7.78 mm of the concentration 80%, and 10.03 mm of the concentration 100%. As for the negative control has no effect. The study stated that the higher concentration of antibacterial agent used, the greater the inhibition zone formed. Based on the result of the analysis of the data by using the One-Way ANOVA Test showed a probability value (p) = 0.000 or value (p) < 0.05, that H0 is rejected and H1 is accepted. The conclusion is that the Extract of stinking vin’e has an antibacterial effect on the growth of E.coli. Keywords: Antibacterial, E.coli, Extract of Sembukan leaf
