Densification or compression is one of many efforts could be employed to improve or modify wood quality. Through simple densification process applied i.e. 50% of compression level, and 20 MPa of pressure at 150 ⁰C it was shown that physical and mechanical properties of 5 year-old of fast growing teak could be improved well. Compared to those of the control wood, the properties of densified wood are much better. Its moisture content is 50.82% reduced; while the others are increased vary. Wood density is increased up to 67.92%, specific gravity increased 82.22%, MOE increased 62%, MOR increased 72%, compression strength parallel to the grain increased 77%, and wood hardness increased 107% (the highest). The densified of teak wood produced is classified to the strength class of II. The paired sample T-test result between control- and treated wood shows that all properties studied are different from each other at confidence interval of 95%.
