Abstract

The anatomical characteristics of jelutung wood come from the forests of common plants region, village of Kelampangan, Sebangau district, Palangka Raya city, Central Kalimantan, Indonesia is observed on this study for the purpose of determining the final use of jelutung timber. The sticks are taken at every 1 cm interval from the pith, middle and near the skin on the three parts, the base and the end of which a diskis 5 cm thick. The sample is carried through a process of maseration to get the results of the fiber dimensions and growing trend from the growths to the skin. The length of fibers on an average of 0,53 mm with a trend toward rising.Vesel’s length at an average of 0,34 mm shows significant variation patterns in value range of 0,002-0,040 mm. The fibers’ average diameter at 11,29 μm has a fairly significant variation pattern in the range of 0,22- 3,37 μm and is the medium diameter wood category. The lumen diameter with a average of 8,15 μm and a relatively significant variation pattern of 0,17-1,77 μm. Thick cell walls with an average of 1,37 μm and significant pattern increases at 0,02-0,38 μm.
