PENGARUH PENAMBAHAN ACIDIFIER EKSTRAK ASAM KANDIS PADA AIR MINUM TERHADAP pH, TOTAL MIKROBA DAN BAKTERI DI SEKUM AYAM KAMPUNG
The purpose of this study was to to determine the effect of adding kandis acid extract acidifier to drinking water on the pH value, total microbes and bacteria (Lactic Acid Bacteria (LAB) and Escherchia colli (E-colli)) in the caecum of kampung chickens. This research was carried out for 2 months in the Poultry Cage, Animal Husbandry Study Program, Department of Animal Technology and Industry, Faculty of Agriculture, Sriwijaya University and 1 month in the Microbiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University. This research used 48 kampung chickens aged 4-4.5 months. The research design used was a Completely Randomized Design (CRD) with 4 treatments and 6 replications consisting of P0 (Control), P1 (kandis acid solution with pH 2.4), P2 (kandis acid solution with pH 3.4), and P3 (Candis acid solution with pH 4.4). The variables observed included pH value, Total Microbes, Total Lactic Acid Bacteria (LAB) and Total Escherchia colli (E-colli) Bacteria. The data was analyzed using ANOVA and if it showed significant differences, it was continued with the Duncan test. The results obtained include the average pH value ranging from 5.34-6.42, total microbes ranging from 6.92-7.83 Log CFU/g, total lactic acid bacteria ranging from 6.78-7.78 Log CFU/g and the total average of E-Colli bacteria in the cecum of kampung chickens ranged from 0.92-3.85 Log CFU/g. The results of this study show that giving kandis acid extract acidifier to drinking water with a pH range of 2.4 - 4.4 has a significant effect (P0.05) on total microbes and total lactic acid bacteria. Giving kandis acid extract with a pH of 3.4 to drinking water showed that the best extract was able to reduce the pH value and total E-Colli bacteria in the caecum of kampung chickens.
