Sondir testing is a pressure test method carried out to analyze the bearing capacity of the soil and measure the depth of the hard or supporting soil layer which is usually called sondir soil. Boring Test is a soil test to determine the soil condition of each layer down to hard soil. The standard set in this test is SPT (Standard Penetration Test) with a value every interval of 2.0m. This standard refers to ASTM D.1586 with the hammer weight used being 63.5 kg with the hammer's free fall height being 76cm. Usually, the boring tool model used has an automatic hammer. The purpose of this paper is to calculate and compare the carrying capacity of a single pile using sondir data and based on the results above the ultimate bearing capacity (Q ult) using the Mayerhoff method, namely BH-1 (145.7 tons), BH-2 (145.7 tons) , Meanwhile using the Aoki De Alencer method, namely BH-1 (0.9279 tons), BH-2 (0.3307 tons). The land carrying capacity permit (Q permit) uses the Mayerhoff method, namely BH-1 (58.28 tons), BH-2 (58.28 tons). Meanwhile, using the Aoko De Alencer method, namely BH-1 (0.37116 tons), BH-2 (0.37116 tons). Based on the results of the calculation of the carrying capacity of the Mayerhoff method which is greater than the Aoki and De Alencer methods, the Mayerhoff method is more efficient than the Aoki de Alencer method.
