Abstract
Fast growing wood species has high availability potential in quantity, but has low quality in its application, so it requires modification treatment to improve the wood quality. Oil heat treatment (OHT) is a wood modification method using vegetable oil as the heating medium. The objective of this research was to investigate the influence of temperature during OHT on the mindi (Melia adezarach) and sengon (Falcataria moluccana) woods. The physico-mechanical properties such as the color changes (ΔL*, Δa*, Δb*, and ΔE), water content, material density, water absorption, mass changes, and compressive strength, were observed. OHT was conducted for 2 h at the treatment temperatures of 180 °C, 200 °C, 220 °C, and 240 °C. The results showed that the increase of temperature indicated an increase of the ΔL*, Δa*, Δb*, and ΔE values at a higher treatment temperature. The increase of temperature exhibited an increase of material density and a decrease of water content, water absorption, and mass changes of wood. The compressive strength of woods slightly increased at 180 °C but decreased as at more elevated temperature. Consequently, OHT of mindi and sengon at 180 °C is recommended to improve color and physical properties of wood and prevent a decrease in compressive strength.
