Abstract
Tulisan ini membahas efektivitas penggunaan data berdasarkan estimasi Jackknife-kriging menggunakan simulasi pelenyapan sampel data pada satu kawasan vein tambang emas. Estimasi berdasarkan sepuluh, dua puluh, tiga puluh dan empat puluh persen pelenyapan data awal menggunakan leave one out. Kualitas perhitung dinilai berdasarkan beberapa ralat dan homogenitas distribusi merujuk kepada koefisien variasi. Berdasarkan perhitungan didapat bahwa, estimasi mengacu sepuluh dan dua puluh persen pelenyapan data masih cukup efektif digunakan. Kata kunci: Sampel data, emas vein, kriging Jackknife, pelenyapan data, ralat This paper discusses the effectiveness of data based on Jackknife-kriging estimation using simulation of gold data sampling in vein region. The estimations based on ten, twenty, thirty and forty percent of leave-oneout of initial loosing data. The quality judged by some errors and also the homogeneity of the distribution refers to the coefficient of variation. Based on the calculations, it is found that the estimation referring to ten and twenty percent of data elimination are still quite effective. Keywords: Data sample, gold-vein, Jackknife kriging, losing data, error
