Identify the types of wood is one part of a series of testing activities in the broad sense which was to determine the type of wood, measure the dimensions of the wood to get the volume and quality setting. From the producer side, the certainty of an important timber species that is in the process of production and marketing. Each type of wood has different properties and characteristics so that the processing also needs different treatment. As for consumers, it will be easier to select a suitable timber for its interests. To determine the types of wood, is not always done by checking the logs of wood in the shape (round timber), but can be done by examining a small piece of wood. In general, having regard to the nature of wood that is easily seen as the appearance of skin, color of wood terrace, fiber direction, presence or absence of latex, etc..
Determination of the types of wood in the form of processed easily done with the rough nature of the notice that is easily seen. For example, teak has a clear image circle grows. However, if the wood was observed in the form of finished goods, which the original physical properties can not be recognized anymore because it has been coated with paint, then the way that can be used to determine the type is to examine the nature of the anatomy or structure.
Basically there are two key properties of wood that can be used to identify the wood, the physical properties (properties of coarse or macroscopic) and structural properties (microscopic properties). Objectively speaking, the nature of the structure more reliable than the physical properties in identifying or determining the types of wood. But to get the results more reliable, better two properties are used together, because the physical properties will support the structure in determining the nature of jenis.Menurut Sunaryo (1997: 93) the physical properties of timber species can be known clearly through the five senses , either by sight, smell, touch, etc. without using tools Among them:
1. Color, generally used is the color of wood terrace,
2. Texture, appearance on the field of structural properties of latitude,
3. Fiber direction, the general direction of the wood-forming cells,
4. Images, whether seen in the field of radial and tangential
5. Weight, generally by using a specific gravity
6. Impression conjecture, namely the impression gained when touched wood,
7. Growth rings,
8. The smell,
