dc.description.abstractThe magnetic susceptibility and morphological properties of iron oxide nanoparticles of natural sand from Logas Village, Kuantan Singingi Regency, Riau Province prepared using ball milling method has been studied. First, the ascollected sand was processed using an iron sand separator (ISS) and followed by NdFeB magnet in order to separate between iron and non iron oxide particles. The product of NdFeB was milled using ball milling for 3 stages and the final result was called the BM3 product. The BM3 product was divided into 5 parts with the same amount of weight and each of them was doped using copper with a concentration of 0 wt.%, 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.% then labelled as BM4A, BM4B, BM4C, BM4D and BM4E, respectively. The BM4A, BM4B and BM4C products were selected to be characterized using Scanning Electron Microscope (SEM). Magnetic susceptibility values of the samples were determined based on magnetic induction (B0) and total magnetic induction (Bt) of a solenoid measured using a PASCO type probe. The results of SEM analysis show that the particle size decreases from 78 , 71 dan 67 with increasing copper concentration from 0 wt.%, 5 wt.% dan 10 wt.%, respectively. The results showed that the susceptibility decreases with increasing doping concentration. The maximum and minimum magnetic susceptibility were for sample 0 wt.%, 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.% and respectively 4395,76382 x 10-5, 4323,22646 x 10-5, 4265,19658 x 10-5, 4207,16669 x 10-5 dan 4134,62933 x 10-5.en_US
