The purpose of this research was to obtain probiotic soyghurt made with several strains of the Lactobacillus plantarum 1 combined with Lactobacillus bulgaricus and Streptococcus thermophilusas filler in chocolate praline. The study conducted by using a complete random design (CRD) with combination of four treatments and four replications. The treatment werePKM₀= S. thermophilus (3%) + L. bulgaricus (3%) +without L. plantarum 1, PKM₁=S. thermophilus (2%) + L. bulgaricus (2%) + L. plantarum 1 RN2-12112, PKM₂= S. thermophilus (2%) + L. bulgaricus (2%) + L. plantarum 1 RN2-53, PKM₃=S. thermophilus (2%) + L. bulgaricus (2%) + L. plantarum 1 RN1-23121. The data were analyzed by analysis of variance, and then analyzed by duncan new multiple range test (DNMRT) at α=5% level. The result showed that the combination of lactic acid bacteria (LAB) did not significantly affected on acidity (pH),total of LAB, water, ash, fat, protein, and carbohydrate content, butsignificantly affected on total lactic acid. Based upon observations, praline chocolate with treatment PKM₁ accordance with SNI standards and somewhat favored by the panelistwhich properties as follow: pH (3,88), amount of lactic acid (1,35%), amount of LAB (9,54 log CFU.ml^-1), water content (79,78%), ash (1,43%), fat (1,15%), protein (2,98%), carbohydrate (14,67%), less sweet, sour, and not bitter taste, brown, and yellowish white colour, a distinctive chocolate and slightly sour aroma, with somewhat thick texture.
