Escherichia coli bacteria can cause urinary tract infections, diarrhea, gastroenteritis, pneumonia, septicemia, and meningitis. The purpose of this study was to determine the diameter of the inhibition zone of amoxicillin and tetracycline antibiotics in inhibiting Escherichia coli bacteria. Experimental research method with antibacterial activity test using paper disc diffusion method. The results showed that amoxicillin and tetracycline antibiotics had inhibition zone diameters of 18.4 mm and 35.76 mm, respectively, with strong and very strong categories. The conclusion of this study is that tetracycline antibiotics are better at inhibiting the growth of Escherichia coli bacteria than amoxicillin.
