Test The Viability Of Lactid Acid Bacteria From Duck’s Intestine On Molasses Medium, Salt Water, And It’s Combination As A Probiotic Rudy Sutrisna1, Christina Nugroho Ekowati2, Fatmawati Putri3, 1Dosen Jurusan Peternakan Fakultas Pertanian, Universitas Lampung E-mail: ABSTRACT Purpose of this research is to know the viability isolate of Lactic Acid Bacteria (LAB) on molasses medium, physiological salt, and combination of two mediums on incubation time until 4 weeks. This research used a mixture of lactic acid bacteria isolates from the duck’s intestine (B4, B7, and B8). The three bacterial isolates were inoculated into the three media specifically salt water, salt water + molasses and molasses. The study was arranged by Randomized Block Design Completely (RAKL) of 3 x 4 factorial treatment pattern (A x B). Factor A is 3 types of treatment media namely media I (salt water), media II (salt water + molasses), and media III (molases). Factor B is time variation used in each treatment medium devided by 1 week, 2 weeks, 3 weeks and 4 weeks. Each treatment was repeated 2 times. This research uses pour plate method with calculation of colony count which will be counted with colony counter. The data in this research are analyzed descriptively. The results showed that molases were able to maintain LAB viability for up to 2 weeks with a population of 2,99 x 106 CFU / ml (6,48 log10 CFU/ ml). In physiological saline medium LAB viability is only up to 1 week with a population of 2,25 x 107 CFU / ml (7,35 log10 CFU / ml). In physiological salts + molasses viability LAB survived for up to 4 weeks with a population of 3,12 x 106CFU / ml (6,50 log10 CFU / ml).
