Penerapan Geostatistika Ordinary Kriging dalam Estimasi Harga Tanah (Studi Kasus: Kecamatan Samarinda Utara Kota Samarinda)

Abstract

The Ordinary kriging geostatistical method is an interpolation method that used spatial data. This method is generally used to estimate coal and mineral resources. However, over time this method is also used in estimating land prices. The purpose of this research is to determine the best model for a land price estimation in Sempaja Selatan Sub-District between spherical models, Exponential models, and Gaussian models, and the best semivariogram model displayed in the form of a contour map. Interpolated using the three models to get the predicted value and calculated RMSE to determine the performance of the model, which the spherical model is the best because it has the smallest RMSE value. In this method, a contour map of the estimation results of land prices in the Sempaja Selatan. The lowest land prices are found to be predominantly located in the northwest and north of Sempaja Selatan Sub-District. The lowest price of the land range from Rp. 279.000,00 to Rp. 900.000,00 per m2 and the highest price of land is predominantly located in the southern part of Sempaja Selatan Sub-District with prices ranging from Rp. 2.982.000,00 to Rp. 4.981.000,00 per m2 .
