Pengaruh Doping Tembaga Terhadap Suseptibilitas Magnetik Dan Komposisi Serta Sifat Kristalinitas Pasir Alam Sungai Rokan Di Preparasi Dengan Metode Ball Milling

---

The effect of copper doping on magnetic susceptibility and composition and
crystallinity properties of Rokan River natural sand has been investigated. Before
going through the ball milling process, the natural sand has been processed using
an Iron Sand Separator (ISS) and Neodynium Iron Boron (NdFeb) magnets to
separate magnetic and non-magnetic particles, so the result is called an ISS
product. The ISS product was crushed through a ball milling process for 70
hours, and the result is called BM 1 product. Furthermore, BM 1 was divided into
3 parts and then doped with copper (Cu) with a concentration of 0; 5; and 10
grams using ball milling for 30 hours and are called BM 2A, BM 2B, and BM 2C
products, respectively. BM 2A, BM 2B, and BM 2C products were identified and
characterized using X-Ray Flourescence (XRF) and X-Ray Diffraction (XRD).
XRF identification results showed that the composition of copper elements
increased from 0.015% to 37.874%. Meanwhile, Fe elements decreased and other
elements such as Al, Si, P, K, Ti, V, Cr, Ca and Mn as well. The XRD test results
for BM 2A, BM 2B, and BM 2C products produced a hematite (Fe2O3) phase
with a hexagonal crystal structure. The crystalite size was calculated using the
Scherrer Equation where the average crystalite size decreased by 26,137 nm;
25,501 nm; and 25.270 nm.
Keywords: natural sand, ball milling, magnetic susceptibility, doping, X-Ray
Diffraction (XRD) and X-Ray fluorescence (XRF)
