This study aims to analyse the bearing capacity of soil at the construction project site of Loa Raya Village Office, Tenggarong Seberang Subdistrict, Kutai Kartanegara Regency, using the Dutch Cone Penetrometer Test method. Tests were conducted at two locations to measure the value of cone resistance (CR) and skin friction at various depths. The test results showed that hard soil layers were only found at depths of more than 20 metres, with CR values above 150 kg/cm². Based on soil bearing capacity analysis using the Schmertmann method for pile and bore pile foundations, and the Sanglerat method for shallow foundations, it was concluded that pile foundations are the best option with an allowable bearing capacity of 150 tonnes. Another alternative is the bore pile foundation with an allowable bearing capacity of 133 tonnes, while the shallow foundation is only suitable for light structures. This research provides recommendations for the foundation that best suits the soil conditions in the field to ensure the stability and safety of building construction
