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...

One indicator of sustainable forest management is the minimum impact of residual stand damage caused by timber harvesting activities. This paper examines stand damage due to timber harvesting on hilly tropical forest, Central Kalimantan. The study was carried out using samples plot of 200 m × 100 m ...

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 ...

Various sawmilling industries of high, medium and small enterprises operate in Indonesia. During log conversion into sawn timber, wood waste occurs in the form of left over cut and sawdust. Small cut waste is lignocellulose material which is potentially used for bioethanol production. This paper...

Currently, Ganoderma lucidum, Pleurotus ostreatus, and P. sajor-caju are prospective fungi for decomposition of pulp and paper industry's waste. This paper studies the possible utilization of rotting fungi spent compost for decomposition of mangium sludge. Initially, the fungi were cultivated for...

Jabon (Anthocephalus cadamba Miq.) has been widely planted by communities as an alternative of building and furniture materials. However, there are two inferior jabon wood proferties i.e. low strength (Class IV) and less durable (Class V). Jabon-Bamboo Laminated Board (JBLB) is one posible product...
