The methods of research is experimentally with using randomized block design (RBD) with 5 treatments and 4 replications. The data were analyzed statistically with using analysis of variance and followed by Duncan’s New Multiple Range Test at level α = 5%. The parameters measured were increase of seedling height, increase of the number of midrib, increase of circle stem, seedling root volume, root crown ratio and dry weight of plants. The results of the research showing that all treatment of formulations Bacillus sp. were tested has non significant effect on all parameters of observation. Formulations of Bacillus sp. with coconut water is the best formulation in increasing of palm oil seedling height and the tendency towards in increase of number of the midrib and plant dry weight.
