Abstract
In the current studyIt has been successfully fabricated and magnetically characterized Fe3O4 composite with polyvinyl alcohol (PVA) matrix. Fe3O4 is obtained from the iron sands of East Lombok.Morphology and elements East Lombok iron sand analysis results from Scanning Electron Microscope Energy Dispersion X-Ray (SEM-EDX) shows that iron sand tends to be spherical and the elements contained in it are Fe (ferum), O (oxygen), Ti (titanium), Al (aluminum), Si (silica), Mg (magnesium), and V (vanadium) and the average diameter of the Particle Size Analyzer (PSA) analysis was 165.76 m. Characterization includes remanent magnetization value (Mr), coercivity (Hc) and maximum energy product value (BH)max.In this study, Fe3O4 was mixed with a PVA matrix with a percentage variation of 70%: 30%; 60% : 40%; 50% : 50% of the total mass of 10 grams. Based on the data obtained from this research, the addition ofFe3O4 causes an increase in the density, remanent magnetization, coercivity, maximum energy product. However, the resulting compressive strength is directly proportional to the concentration of the matrix added.
