There are many methods that have been used in design of pile foundation, from most simple one up to modem one based on new Soil Mechanic technology. But it is still got that the calculated bearing capacity of pile based on those methods will be different compared with field loading test result. So, it is logic if it was needed a relative simple model that has enough accuracy in prediction of safe pile bearing capacity. in intending to get the Realibility Index of ce ucuk pile bearing capacity because of axial compression load in rerucadk pile foundation design system based on cone penetrometer test data on Pontianak soft soil, it has been done research to twenty-three point of seven location in Pontianak City. From the cone penetrometer test and loading test data have been arkadated and interpreted pile bearing capacity of each data by Schmerbnann & Nottingham Method and Elastic-Plastic Line Method. Analysis has been done to the model or formula that has been used by comparing two of bearing capacity to find influence error factor such as influence of model error (NJ), influence of test error (NJ) and influence of natural soil variation (Ni. Then analysis of single cerucuk pile foundation realibility was done by involving bearing capacity and load uncertainty by using Load Resistance Faktor Design Method. From analysis that has been done, it was found out that for ceruauk pile foundation design can be used the Realibility Index =3.72 with probability offailure =10 , and for practical necessity of cent auk pile foundation design, recommended this formula 0.5 Rm < 1.2 Dn + 1.65 Lm, Where was got from model II Scmertmann & Nottinham Method.
