Research on rubber wood (Hevea brasiliensis) treatment to enhance dimensional stability of wood after Potassium Silicate (K2SiO3) treatment. Experimental research on treating Rubber wood with Potassium Silicate (K2SiO3) with different concentration levels and treatment times. Then check the expansion of Rubber wood (Hevea brasiliensis) along the grain directions. The results show that concentration and treatment time are two factors that directly affect the reduction of expansion (swelling) of Rubber wood, which causes the wood to have a significant improvement in physical properties. The optimal result is achieved based on the established correlation equation. Rubber wood with a potassium silicate (K₂SiO₃) concentration parameter of X₁ = 1.414 (N = 27.07%) and a treatment time of X₂ = 0.348 (T = 3.348 hours): the tangential wood expansion rate is 2.9547%, the non-treatment sample is 6.4813%, the radial wood expansion rate is 1.0632%, the non-treatment sample is 4.1366%, and the longitudinal wood expansion rate is 0.0417%, and the non-treatment sample is 0.6793%. These results indicate that reducing wood expansion in the fiber directions significantly increases the dimensional stability of Rubberwood.
