Formaldehyde emission and physical-mechanical properties of particleboard bonded with urea formaldehyde (UF) could have negative effects on human health, specially when used in a room with limited ventilation. To reduce formaldehyde emission, an adsorbent can be added into adhesive mixture. This...

Petroleum consumption is increasing, while the supply is continuously depleted. Currently, the alternative biofuel such as bioethanol, biodiesel and bio-oil have been developing from various natural sources, including forest product's waste. This paper studies the characteristic of bio-oil made of...

Anatomical properties is necessary for wood species identification. This paper observes anatomical properties of six wood species originated from Papua. Wood species studied include: ketapang (Terminalia complanata K. Schum.); pala hutan (Gymnacranthera paniculata (A.DC.) Warb.); bipa (Pterygota...

White-rot fungus, Basidiomycetes is an unique group of microbes among the major decomposers of plant polymers or biomass. Their existences are under pressure due to Indonesian tropical forests degradation caused by forest fires, excessive exploitation, land conversion and biopiracy. Based on...

Timber harvesting in forest plantations of PT Korintiga Hutani was undertaken using lenght limitation of 4.10 m and minimum diameter of 10 cm. These limitations have created numerous trunk wastes in the field. Harvesting efficiency improvement is being considered by converting the wastes into wood...

Forest harvest is the first activity to undertake in extracting logs from the forest site. The amount of wood wastes generated during logging operation can be used for measuring the value of exploitation factor (FE). The greater FE indicates more efficient of wood utilization. Indonesian government ...

Information regarding physical properties of bamboo is essential for interpreting its dimensional stability, while drying properties are needed as a basis in determining the optimum drying temperature. This research was aimed to investigate the effect of bamboo species and position at the culm on...

There are about 4,000 timber producing trees grow naturally in Indonesia, which comprise of commercially and lesser known wood species. Wood chemical component analysis is one indicator for timber utilization. This paper studies the chemical components of five lesser-known wood species originated...

All kinds of ligno-cellulose fiber stuffs are technically suitable for hardboard manufacture. In Indonesia, currently the available conventional ligno-cellulose fibers (esp. tropical natural-forest woods) become scarce and depleted. Meanwhile, domestic fiberboard-production is lower than its...

Rattan utilization is mainly determined by its physical and mechanical characteristics of density and tensile strength, where the higher the physical and mechanical properties, the better quality of the cane. In South East Asia region including Indonesia, two of eight genera, Calamus and...
