Ribbon of magnetite (Fe{sub 3}O{sub 4})/Polyvinyl Alcohol (PVA) nanoparticles have been successfully fabricated with various concentration of PVA synthesized by co-precipitation method. Particle size of nanoparticles Fe{sub 3}O{sub 4} sample and ribbon Fe{sub 3}O{sub 4}/PVA 25% sample is about 9.34 nm and 11.29 nm, respectively. The result of Vibrating Sample Magnetometer (VSM) showed that saturation magnetization value decreased from 76.99 emu/g to 15.01 emu/g and coercivity increased from 49.30 Oe to 158.35 Oe as increasing concentration of PVA. Atomic Force Microscopy (AFM) analysis showed that encapsulated PVA given decreasing agglomeration, controlled shape of nanoparticles Fe{sub 3}O{sub 4} more spherical and dispersed. Surface roughness decreased with increasing concentration of PVA.
