Jayapura city, located in eastern Indonesia, is the center of the most populous settlement in Papua Province. Jayapura City is an area with a fairly fast economic growth rate. Constructing civil buildings needs special handling, especially in foundation design. To design a foundation, information on the quality of the soil that is able to support the load is needed so that the foundation can rest well on it. Therefore, a preliminary study is needed, namely geotechnical investigations can be carried out by direct investigation methods in the field (in situ test), one of which is the CPT (Cone Penetratinon Test). From the calculation of the soil bearing capacity obtained from the CPT method, it is used as a zoning map using ArcGis 10.3 software. Based on the distribution of CPT data in the city of Jayapura which was processed using ArcGIS 10.3, the results of the depth of soil density with a qc value of 20 kg / cm2 were obtained at a depth of 0.6 meters to 16 meters, the results of the depth of soil density with a qc value of 40 kg / cm2 were obtained in a depth of 1.6 meters to 18 meters, and the results of the depth of soil density with a qc value of 120 kg / cm2 are obtained at a depth of 2.9 meters to 20 meters.
