Modification of Fast-Growing Wood into Magnetic Wood with Impregnation Method Using Fe3O4 Nanoparticles

Fast-growing wood is rarely used by the community because of its low quality. This study aimed to modify sengon (Falcataria moluccana) and jabon (Anthocephalus cadamba) into magnetic so they have new functions. In this study, modification process was performed impregnating five-level concentrations Fe3O4 nanoparticles dissolved in two different dispersants, namely water a mixture furfuryl alcohol water. The impregnation initiated vacuum -0.5 bar, followed pressure 1 bar for 120 min. addition solution significantly increased physical properties wood. presence also proven Fe-O groups observed from FTIR spectrum analysis. field strength as concentration level increased. Based on results research, best treatment obtained with 7.5%. Keywords: wood, impregnation, nanoparticles, nano
