Abstract

Various wood producing tree species grows in large forest area of Indonesia. Wood could be used for various products such as furniture, crafts, building constructions and other products like charcoals. Utilization of products is also generaly associated with physical, chemical, anatomy and mechanics characteristic of wood. This research aims to determine chemical and extractive composition of five lesser-known wood species from West Kalimantan, namely kumpang, bengkulung, sawang, kempili and ubar wood, and their influences on charcoal properties produced from corresponding wood types. The chemical and extractive components of the five wood types were analyzed according to the Indonesian National Standard (SNI) method.
