Abstract
In the near future, wood demand will be fulfilled by local fast growing woods from community forest. Among those, samama (Anthocephalus macrophyllus) is an endemic wood in Celebes and Moluccas. This species has been cultivated throughout Indonesia and usually harvested at age of less than 10 years. This research was conducted to examine the quality of samama wood at 8 and 10 years old. Each age group was represented by three healthy trees. Samples were made from 1 cm segmentation from pith to bark. Modified exponential curve was used to determine the transition of juvenile and mature wood in which maturity limit was achieved when growth parameter had reached the asymptote line. The quality parameters were specific gravity, moisture content, fiber length, fiber wall thickness and microfibril angle. The result showed that the first 6–8 segmentations from the pith were still juvenile, while the subsequent segments were mature wood. The 8 years old had 33.3–38.9 % of juvenile portion, while it was only 30.4–34.8 % in the 10 years old. This finding will be important in considering a proper technology for samama wood processing.
