Wood as a construction material is currently increasingly limited. One alternative material as a substitute for construction wood is laminated bamboo. Laminated bamboo is a product made from several bamboo slats or bamboo slats that are glued together with the fiber direction parallel to the board with several requirements, among others, must have dimensions of length, width, and thickness that can be converted into boards or blocks. The type of bamboo that will be used in this research is petung bamboo (Dendrocalamus asper). Petung bamboo was chosen because it has a diameter that can reach 20 cm with a wall thickness of 1-3 cm, making it suitable for use as laminated bamboo. The purpose of this study was to determine the effect of blade arrangement on the physical and mechanical properties of petung bamboo laminated boards. The method used in this study is an experimental method with a non-factorial completely randomized design experiment with two treatments and three replications. Based on the results of the study, the arrangement of the laminated board blades did not significantly affect all tests of the physical and mechanical properties of the petung bamboo laminated board. All tests of physical and mechanical properties have complied with JPIC standard No. 1152 2007 except in the MoE test does not meet the standard. Based on the strength class of the laminated board, the bamboo petung laminated board is classified as strong class III which can be used as a protected heavy construction material.

Currently, need for wood as a raw material for making boards has increased, which has reduced the availability of forest resources. To overcome this problem, industrial waste or other lignocellulosic materials are used to make particle board with the aim of efficient use of wood. Particle board has advantages, namely the use of raw materials can be either wood or non-wood waste. Therefore, particle board processing can overcome the problem of handling wood waste which has not been optimally carried out. This research aimed to analyze the physical properties of particle board made from bamboo and sugar palm waste. This study used an experimental method with a completely randomized design (CRD) with one factor (adhesive content), namely 10%, 12%, and 14%. The results of this study showed that physical properties of bamboo particle board at adhesive content of 10%, 12%, and 14% ranged from, respectively: water content (10.26%, 9.96%, dan 9.79%); density (0.69 gr/cm3, 0.68 gr/cm3, dan 0.71 gr/cm3); thickness swelling (21.57%, 20.07%, dan 19.23%). While the palm sugar particle board with adhesive content of 10%, 12%, and 14% respectively: water content (11.29%, 10.91%, dan 10.22%); density (0.70 gr/cm3, 0.69 gr/cm3, dan 0.71 gr/cm3); thickness swelling (26.00%, 22.90%, dan 22.85%). From the physical properties of the two types of particle board, the water content and density of particle board fulfilled JIS A-2003 standard, while thickness swelling did not fulfilled JIS A-2003 standard. Based on the value of moisture content and density, the use of bamboo particle board and palm sugar is suitable for interior materials.

The most potential biomass to be developed with a high lignocellulose content is wood. Calorific value estimation based on the results of biomass analysis such as the proximate test can be used as an alternative to predict the calorific value accurately, quickly, and economically. Therefore, in this study, it is important to measure the calorific value simply using the proximate method with an analytical approach to the chemical content of the raw material. This study used three species of wood consisting of jabon (Anthocephalus cadamba Miq), ulin (Eusideroxylon zwageri), and api- api (Apicennia sp.). This study's chemical components that eximined in this study consist of extractive, holoselulose, and lignin content. The proximate analysis consists of volatile matter content, ash content, fixed carbon, and calorific value. The results show that ulin wood has the highest calorific value (20.13 MJ/kg), then api-api wood and last jabon wood. The high amount of calorific value is contributed by the high value of lignin, extractive, and fixed carbon.

Research on improving the quality of rajumas wood (Duabanga moluccana) through heat treatment aims to determine the effect of heat treatment on the physical and mechanical properties of rajumas wood. This study used an experimental method with an experimental design in the form of a non-factorial complete randomized design, namely the temperature factor with the treatment of three temperature variations of 140oC, 160oC, 180oC and three replications. Heat treatment carried out in this study caused changes in the three parameters of the physical properties of rajumas wood tested, namely moisture content, density, and dimensional stability. Changes in the physical properties of wood occurred in all three variations of treatment temperature (140oC, 160oC, 180oC). Heat treatment results showed a positive response that can improve the physical properties of rajumas wood. Heat treatment showed an increase in MoE and MoR wood mechanics properties as the treatment temperature increased. The use of 160oC heating temperature gives the highest MoE and MoR improvement results and the use of higher heating temperatures will reduce wood mechanics. Heat treatment method can be an effective method in improving wood properties.

Nowdays, there is growing interested in development of afrika wood utilization. Afrika wood is one fast growing species from plantation forest. The objective of this research was to evaluated of characterization of afrika fiber for pulp and paper production. Anatomical properties of afrika wood were also investigated. Determination of characterization of fiber dimension was conducted based on Tappi (1989). The resulted showed that afrika wood have type of porous namely soliter and radial multiple porous. The parenchyma and ray characters were paratracheal parenchyma confluent and multiseriate types. For fiber characteristic obtained by fiber length, fiber diameter, lumen diameter, and cell wall thickness were 935.33 µm, 28.52 µm, 21.29 µm, and 3.62 µm respectively. The derived value of afrika fibers obtained by runkel ratio, felting power, muhlsteph ratio, coefficient of rigidity, flexibility ratio, and fiber length were 0.43, 35.02, 20.51, 0.12, 0.76, and 935.33 µm respectively. Based on the derived value of afrika fibers, it qualifies as Grade II material for pulp and paper production. Afrika wood can be used as raw material for pulp and paper production.
