dc.description.abstractIndonesia has abundant natural sand and there are natural magnetic minerals, one of which is iron sand. Where one of the purposes of this iron sand is to purify water that is contaminated by dyes. To increase its ability to degrade the dye, it is doped with nickel using the ball milling method. The effect of nickel doping on the value of magnetic susceptibility and elemental composition of iron oxide nanoparticles of natural Logas sand has been studied. Iron oxide particles were separated from nonferrous particles in the sand samples using Iron Sand Separator (ISS) and Neodymium Iron Boron (NdFeB) magnets. The NdFeB product was milled using the ball milling method for 3 stages. Each stage of the product is processed with NdFeB magnets to separate ferrous and non-ferrous oxide particles. The final product of ball milling is divided into 5 parts, then each part is doped with Ni (Nickel) as a function of weight concentration using ball milling for 20 hours where the composition (Fe2O3)100-xNix where x= 0%; 5%; 10%; 15%; and 20%. Magnetic susceptibility was calculated based on the value of the magnetic induction of the solenoid (B0) and the total magnetic induction of the solenoid (BT) using the Pasco PS-2162 magnetic probe as a function of the electric current of 100 mA; 200mA; 400mA; 600mA; and 800mA. The results showed that the magnetic susceptibility increased with increasing Nickel Nickel concentration. The highest magnetic susceptibility value was found in the sample (Fe2O3)0.8Ni0.2 of 4743.94 x 10-5. The results of element identification using X-Ray Fluorescence (XRF) confirmed the presence of magnetic elements such as Al, Ti, Mn, Fe, and Ni and nonmagnetic elements such as Si, P, Ca, Cr, Zn, Ag, and Pb. The research results have the potential to be applied as element identification or composition test on the sample (Fe2O3)100-xNix.en_US
