The global economic crisis that hit the world turned out to cause a decline in exports. Therefore, in need of creative industries in raw materials production process and marketing. One of the creative efforts is the selection of wood raw materials for the industry is by using environmentally friendly wood species because it can reduce global warming. Still, the selling value of products in the export market is very high. The study design used a complete randomised design with an advanced Tukey test based on one factor, which is the types of wood that are Sengon, Waru Gunung, and Johar wood. The parameters observed are specific gravity, wood colour, adhesive strength, and formaldehyde emissions. The results showed that are Sengon, Waru Gunung, and Johar wood have different specific gravity, wood colour, and formaldehyde emissions. The average density of Sengon wood is 0.236, Waru Gunung wood is 0.570, and Johar wood is 0.654. The adhesive strength of Sengon wood 41.948 kg/cm2, Waru Gunung wood is 45.555 kg/cm2, and Johar wood 54.040 kg/cm2. Besides, the formaldehyde emissions for Sengon wood is 0.575 ppm (0.575 x10-3 ug/ml), Waru Gunung wood 0.462 ppm, and Johar wood 0.473 ppm. The higher the wood specific gravity, it will result in the wood colour and lower formaldehyde emissions. Wood with medium to high density (Waru Gunung and Johar) acknowledged as the environmentally friendly woods, and it can be used as raw material for creative industries.
