Jabon (Anthocephalus cadamba) is a fast-growing wood species that widely utilized for light construction and other purposes in Indonesia. The objectives of the current study were to determine effects monoethylene glycol (MEG) SiO2 nanoparticles (nano SiO2) impregnation treatment on dimensional stability density jabon identify characteristics impregnated wood. Wood samples immersed water (as untreated), MEG, 0.5% MEGSiO2, then by applying 0.5 bar vacuum 60 min, 2.5 pressure 120 min. results showed with MEG Nano had significant effect Polymers can fill cell walls indicated increasing weight percentgain, antiswelling efficiency, bulking effect, density, decreasing uptake value. morphology using SEM MEGSiO2 polymers cover part pitsin vessel wall jabon. This finding was reinforced EDX showing silicon content increased due addition nano. XRD diffraction pattern degree crystallinity samples. Overall, led most improvement 5-year-old this study.
