Wood quality of five year-old of cultivated Red Meranti (Shorea leprosula Miq.) was studied in order to assure its proper utilization. The evaluation was conducted based on fiber dimension and physical properties of wood. Fiber dimension was measured through maceration specimen, while green moisture content, wood density, and specific gravity were measured following the modification of BS 373.75. Result shows that quality of Red Meranti wood studied was similar to that of naturally grown, except for its fibers which were shorter and thinner than those of naturally grown. It was found that wood quality of each tree was homogenous and even. Result also shows that average values of fiber length, cell wall thickness, moisture content in green condition, wood density and SG are 968.12 µm, 2.72 µm, 104.57%, 0.81 g/cm3, and 0.50, respectively. The wood is categorized as strength class of III, therefore, this Shorea leprosula wood is potential as raw material for plywood and furniture manufacturing, as well as for the 3-rd class of structural and other purposes. The trees unfortunately have not produce the mature wood yet, and the wood produced is not suitable for the highest quality of pulp and paper manufacturing.

The effect of NaOH, succinic acid and their combination used as pretreatments on selected properties of densified wood samples of pisang putih (Mezzettia spp.), nyatoh (Palaquium spp.) and sepetir (Sindora spp.) has been studied. The properties of these samples were then compared with those of untreated wood (control) and densified wood samples without any pretreatment (HD wood). For alkali-pretreatment, after immersion in 10% NaOH (w/w) for 1, 2 and 3 h, the samples were immediately compressed; for acid-pretreatment, the sample was impregnated with 10% succinic acid (w/w) using a vacuum of −50 kPa for 30 min and a pressure of 7 bar for 2 h before pressing; while for the combination-pretreatment, the sample was initially immersed in 10% NaOH then impregnated with 10% succinic acid (w/w) and finally densified/compressed. Compression was applied in a radial direction and carried out in an open system using a hot press machine at 180 °C and 7 MPa specific pressure for 30 min with a 40% compression ratio. The results showed that densified wood with or without pretreatment had a higher specific gravity (SG) than the control, whereas sepetir wood showed the greatest increase in SG. The alkali- and combination-pretreatments resulted in a higher C-set value than in the control, HD and acid-pretreated samples. Acid-pretreatment resulted in the best improvement in dimensional stability compared to the other pretreatments. Increasing the immersion time in NaOH solution was proven to be able to increase dimensional stability both in alkali- and combination-pretreatments, although water absorption values varied.
