Based on the results of the geotechnical investigation, it was concluded that the Bearing Capacity Value of the Shallow Foundation Permit from the qc Data was obtained at No. Test. S - 1, with a depth of 5 meters, the permitted bearing capacity (Qi) was 3.8 (Ton / m2) with a square foundation width B = 1 m and No. Test. S – 2, with a depth of 5 meters, the permissible bearing capacity (Qi) is 4.53 (Ton/m2) B = 1 m
