Salmonella paratyphi A causes enteric fever, which is paratyphic fever which attacks the intestines and is acute. Apple cider vinegar contains acetic acid, apple cider vinegar contains organic acids, namely acetic acid and amino acids, flavonoids, polyphenols, pectins and it's also rich of vitamins and minerals. The acetic acid content of apple cider vinegar acts as an antimicrobial. The objective of the research was to determine the concentration of apple cider vinegar which was effective in
... hibiting the growth of Salmonella paratyphi A bacteria. The type of research used was true experiment using posttest only control group design. The results obtained are apple vinegar can inhibit the growth of Salmonella paratyphi A bacteria with the result that the inhibition zone diameter at a concentration of 15% is 8,8 mm, 20% is 11,22 mm, 25% is 11,92 mm, and 30% is 13,05 mm, whereas in the positive control group it was obtained 29,95 mm and the negative control group was 0 mm or no inhibition zone is formed. The different test using Kruskal Wallis resulted in a value of sig (p) < (0.05) so it indicated that there were differences in the inhibition zone for the growth of Salmonella paratyphi A bacteria against various concentrations of apple cider vinegar. It was concluded that there was an antibacterial activity of apple cider vinegar against the growth of Salmonella paratyphi A bacteria and the effective concentration that could inhibit the growth of Salmonella paratyphi A bacteria was at 30% concentration.
