Anatomi Kayu Palele (Castanopsis javanica) Wood Anatomy of Palele (Castanopsis javanica)

As an effort  to overcome scarcity of raw material for wood processing industries, utilization of wood from various lesser known species should be conducted. Wide prospects of utilization will be opened when complete data of species and their properties are available.The aims of this research is to get microscopic features concerning to the wood anatomical structure of Palele (Castanopsis javanica) at the vertical and radial directions. Observation of wood anatomical structures in accordance to International Association of Wood Anatomist standard; includes diameter, height and amount of vessel; also height, width and amount of wood rays; percentage of vessels, percentage of rays, axial parenchyma and percentage of fiber, fiber diameter, fiber lumina, and fiber wall thickness.In this research it is found that wood vessels are oval to round, solitary vessels in radial arrangement, vessels consist of rare tylosis, wood diffuse porous,  alternate pits with simple plate perforation.  Wood rays is uniseriate heterogeneous, two types of axial parenchyma, i.e. : apotracheal scalariform and paratracheal with narrow short bands and wavy.  Fiber quality includes in category class II. This wood has medium to long size fiber with thin walled and wide of lumina. It is predicted that wood fiber of Palele can be used as raw material for paper with smooth surface and medium strength

Serat Eksentrik pada Kulit Kayu Marobamban Eccentric Fiber In The Bark Of Marobamban

Type and dimension of cell, especially fiber and tracheid, generally is used as a standard of utilization and quality of product. Beside type and the presence of fiber, up to now unusual fiber dimension in the bark of Marobamban (Helicia spp.), is not yet discovered. Traditionally, this swamp species is planted merely for protecting land from erosion, but the other part of the trunk like bark and its fibers are not yet utilized. The aim of this research is to know the anatomical structure of Marobamban bark and the presence of unusual fiber dimension as well as the fiber class quality. This research was conducted in Wood Anatomy and Identification Laboratory Forestry Faculty, Mulawarman University for one month. IAWA (International Association of Wood Anatomist) is used as observation and analysis standard. The result shows that outer bark with grey white coloured has thorny fiber along the surface and hooks to each other. Fiber length is classified as short category with big diameter. Fiber lumina and wall thickness are classified to moderate and very thick walled respectively. Fiber quality is classified to the third class
