The bored pile foundation serves to carry and hold the load that works on it, namely the upper construction load to the hard soil layer without excessive subsidence. The amount of carrying capacity of a pile foundation can also be known from the loading test testing. This study is to calculate and compare the bearing capacity of bored piles from Standard Penetration Test (SPT) data using the Reese and Wright method and calculate the capacity of bored piles from the loading test results with the Davisson method, Mazurkiewich method and Chin method. The results of the calculation of the carrying capacity of the foundation there are differences in values both seen from the use of methods and differences in points reviewed. The bearing capacity of a single bored pile foundation from the Standard Penetration Test point (BH-3A P.1) at a depth of 52 meters with the method used by Reese and Wright is cohesive at 2972.55 tons and non-cohesive at 1987.84. The bearing capacity of a single bored pile foundation from the Standard Penetration Test (BH-4A P.2) point at a depth of 49 meters with the method used by Reese and Wright is cohesive at 3085.87 tons and non-cohesive at 1954.12 tons. The ultimate carrying capacity is based on the results of the loading test carrying capacity at point P1 with a depth of 52 meters using the Davisson method of 1755 tons, the Mazurkiewich method of 1630 tons, the Chin method of 16799 tons. . The ultimate carrying capacity is based on the results of the loading test carrying capacity at point P2 with a depth of 49 meters using the Davisson method of 1910 tons, the Mazurkiewich method of 1908 tons, the Chin method of 2915 tons. The efficiency using the simple method is 0.530, the Converse Laberre method is 0.655, the Los Angeles method is 0.800, the Seiler–keeney method is 0.800.
