This research was aimed to determine the effect of Pediococcus pentosaceus isolated from dadih, West Sumatra on water content, pH value, total bacteria colonies of aerobes, total lactic acid bacteria colonies, shelf life, foam power, skin irritation, and viscosity. This research uses 2,000 ml of PE goat milk (Peranakan Etawah) obtained from Sathersun Air Dingin Padang farm. Materials needed for this study include probiotics of 120 ml where 1 ml of Pediococcus pentosaceus has a dose of 2.4x109 CFU/mL, KOH of 60 g, stearic acid as much as 140 g, 180 ml aquadest, 200 ml virgin coconut oil (VCO). The research method using randomized block design (RBD) consisted of 4 treatments with 5 groups as replicates where a formula of soap consists of: 100 ml goat milk, probiotics Pediococcus pentosaceus according to treatment (A = 0 ml, B = 1 ml, C = 2 ml, D = 3 ml). The results showed that the addition of Pediococcus pentosaceus to the probiotic liquid soap was significantly different (P<0.01) lowered the water content, pH value, the total colonies of aerobic bacteria, increased the total lactic acid bacteria colonies, and shelf life, but gave no significant different effect (P>0.05) to foam power, skin irritation, and viscosity. The conclusion of the study showed that the best addition of Pediococcus pentosaceus in treatment of 3 mL with a dose of 2.4 x 109 CFU/ mL was able to lower water content by 75.56%, pH to 6.11, total colonies of aerobic bacteria - 16.40 x 103 CFU/ mL, total lactic acid bacteria colonies - 8.52 x 109 CFU/ mL, foam power 2.36, skin irritation 0.05, viscosity 0.82 , and increasing shelf life for 32 days is the best in producing goat milk liquid soap.
