Diarrhea is an increase frequency and decrease consistency of fecal when compared with the bowel condition of normal individuals. The high incidence of acute and chronic diarrhea encourages researchers to keep trying to find new antidiarrheal drugs, especially from plants. The leaves of Moringa (Moringa oleifera Lam) contain tannins which are polyphenolic compounds and has benefits as anantidiarrheal.This study aims to determine the activity of the ethanol extract of moringa leaves as an antidiarrheal by looking at intestinal motility. The extraction process was carried out by maceration method using ethanol 70%..The result research is the average value of the treatment ratio is smaller than the negative control group. The average value of the ratio of the group was given by ethanol extract of moringa leaves at a dose of 9.1 mg / 20 g body weight was 0.664; ethanol extract of moringa leaves at dose of 18.2 mg / 20 g body weight was 0.434 and ethanol extract of moringa leaves at dose of 36.4 mg / 20 g body weight was 0.389. From this value, it is known that the ethanol extract of Moringa leaves has an antidiarrheal effect by inhibiting intestinal motility. The effect of the ethanol extract of Moringa leaves in inhibiting intestinal motility is best at a dose of 36.4 mg / 20 g body weight with an average value ratio of 0.389.
