This study uses a completely randomized design factorial 3X 5 (3 <br />X 5 treatment of bacterial isolates pH) with three replications. The first factor <br />consisted of pH 4, pH 5, pH 6, pH 7, pH 8, and the second factor that isolates B2, B7, <br />B8, whereas the parameters consists of a clear zone. The amount of production is <br />determined by the size of the diameter of antibacterial inhibition zone against <br />Salmonella sp. Differences in the production of antibacterial determined based on the <br />results of analysis of variance. The treatment significantly further test BNT at 5% <br />level. The results showed that the effect of media pH test based on the potential for the <br />production of antibacterial effect. The diameter of the largest clear zone produced by <br />B7 isolates at pH 6 was 17.2 mm, 17.1 mm B8 and B2 at pH 7 at 16.7 mm. The <br />smallest diameter of the clear zone produced by B8 at pH 4 was 15.1 mm, B2 at pH 6 <br />there is a clear zone of 12.7 mm and isolate B7 at pH 5 of 11.5 mm <br /> <br />Keywords: Antibacterial, Lactic Acid Bacteria, pH, Salmonella sp, Clear zone</p>}, number={3}, journal={Jurnal Penelitian Pertanian Terapan}, author={Sutrisna, Rudy and Ekowati, Christina Nugroho and Sinaga, Edelina Sinaga}, year={2017}, month={Jul.} }
