Description
Summary:The increasing of population directly affected to the increasing timber demand nationaly. Optimum timber utilization is requires to solve those problem. Teakwood obtained from thinning is a huge potency which is need to be research from its properties including fiber dimension, physicals and mechanicals to obtain a proper processing. This study used completely randomized design with two factors including tree ages (12, 15, 20 and 25 years) and radial position (near pith and near bark). The samples of fiber dimensions evaluated according TAPPI Standard 1957 and physicals mechanicals were evaluated according to British Standard Method 373 1957. Teak obtained from KPH Kendal thinning had similar fiber dimensions, physical and mechanical properties. The value of fiber dimensions including fiber length, fiber diameter, lumen diameter and fiber wall thickness were 0.91-1.39mm, 23.11-26.5μm, 10.83-13.46μm and 5.45-7.18μm, respectively. Physical value including moisture content (MC) on wet and dry condition were 21.99-43.63% and 14.85-17.44%. Specific gravity of wood in wet, air-dry and oven-dry condition were 0.46-0.56
