Model Semivariogram dalam Menaksir Sebaran Kadar Ni Menggunakan Metode Ordinary Kriging (Studi Kasus Endapan Nikel Laterit di PT Vale Indonesia Tbk)

Abstract: Geostatistik merupakan suatu metode dalam ilmu statistika yang digunakan dalam distribusi keruangan. Geostatistik memuat  korelasi antar sampel data yang di dalamnya terdapat variabel teregionalisasi yang disebut kriging. Kriging mampu memberikan taksiran yang sangat baik dengan meminimalkan variansi kesalahan melalui korelasi antar sampel titik bor. Identifikasi model dalam semivariogram diperoleh model terpilih yaitu model eksponensial untuk lapisan limonit, model spherikal untuk lapisan saprolit, dan model … Show more
