This research analyzes how to interpolate the beneficial content of laterite nickel mining in production at PT. Raihan Catur Putra. The data used in the research are 51 coordinates of the mining business license of PT. Raihan Catur Putra, Morowali regency in 2018. To answer this question, the first thing that needs to be done is to determine the threshold value. Second, coded data based on threshold values. Third, calculate the experimental semivariogram values. After that, calculate the theoretical semivariogram values and then choose the best model of the theoretical semivariogram based on the smallest MSE value. The last step, interpolation the content of laterite nickel based on the best model and plot of the predicted area. The result showed the best model is spherical with an MSE value of 0.5055551. One of the profitable laterite nickel mines in production at PT. Raihan Catur Putra is at 2.962945; 122.1932 with an opportunity value of 0.99. In the interpolation plot, the favorable area has an orange degradation whose distribution conditions are almost comprehensive. [ABSTRACT FROM AUTHOR] |
