Abstract

Activated charcoal from biomass can be used for various applications because its high porosity. One of the utilizationfor activated charcoal as catalyst raw material from empty palm oil bunches. This study aimed to determine thecharacteristics of activated charcoal with nickel (Ni) impregnation as catalyst raw material in the upgrading bio-oil.Activated charcoal used 10%, 15%, and 20% H3PO4was immersed for 24 hours, and calcinated at temperatureof 750°C with steam activation time for 60 minutes. The optimum of the manufacturing of activated charcoal withwith 10% H3PO4, then impregnated with nickel in various concentration: 1%, 2%, and 3%. Results showed thecharacteristic of nickel impregnated activated charcoal were as follows: iodine absorbance capacity 554–756 mg/g,methylene blue absorbance capacity 38–90 mg/g, surfaces area 96–218 m2/g and pore diameter of 8.48–16.21micron meter.

Abstract

Waste of sengon wood could be used as an alternative material in the manufacture of particleboards. However,particleboards made from sengon has seome inferior physical and mechanical properties, which did not meet the Japanesestandard (JIS A 5908: 2003). The aim of this research is to improve the physical and mechanical properties ofsengon particleboard using sorghum bagasse in various raw material composition using citric acid adhesives. Citric acidwas used as a binding agent with 20% adhesive content based on the weight of the air-dried particle. Compositionof fiber mixtures between sengon and bagasse sorghum were set in 100:0, 75:25, 50:50, and 25:75 wt.%. Thetargetted density of particleboard was set at 0.80 g/cm3. The hot-pressing conditions of particleboard manufacturingwere 200°C for 10 min. The physical and mechanical properties of the particleboards were evaluated according toJIS A 5908: 2003 standard. The results showed that the density, moisture content, thickness swelling, modulus ofelasticity, modulus of rupture and internal bond met the requirements of the JIS A 5908-2003 standard. Thus, theadditional of bagasse sorghum becomes an alternative way to enhance the physical and mechanical properties of sengonparticleboard. The addition 75% bagasse sorghum had better moisture content, water absorption, thickness swelling,modulus of elasticity, and modulus of rupture of particleboard.

Abstract

Chemical components of polyphenols extraction products from mahogany wood (Swietenia macrophylla) andcopolymerized with resorcinol and formaldehyde in alkaline condition, resulting in a resin that can be used as an adhesive.This paper presents the use of tannin from mahogany bark extract copolymer as laminated wood adhesives. Researchmethods include adhesive formulations, testing of the physical-chemical properties of adhesives, manufacture and qualitytesting of the laminated products, and data analysis. The treatments imposed in this study were adhesive formulations,wood species used as raw materials, and types of products made. The results show that the copolymerized tannin extractfrom mahogany bark could be used as an adhesive in making laminated wood beams (glulam) and laminated boardsof the three wood species i.e. tusam (Pinus merkusii), jabon (Anthocephalus cadamba), and sengon (Falcatariamoluccana). The bonding quality and mechanical properties of both types of laminated products were comparable withthose of similar products glued with the imported exterior adhesive with low formaldehyde emission, and classified as F** or F *** with the adhesive ratio of T:R:F = (1:0.025:0.1)%, and T:K:F = (1:0.03:0.1)%.

Abstract

Bamboo has been recoqnized as wood substitute materials by convertting them into engineered bamboo products. Toincrease bamboo utilization efficiency, the waste generated from bamboo processing can be used further as raw materialsfor particleboard manufacture. Besides to get relatively thick and strong material, the bamboo particleboard can beused as a core layer for sandwich panel. The objective of this research was to determine characteristics of sandwichpanel with particleboard as the core layer. There were four types of particleboard used as the core layer of sandwichpanel i.e bamboo particleboard with density of 0.45 g/cm3(A1) and 0.55 g/cm3(A2), and the mixture of bamboojabon particleboards with density of 0.45 g/cm3(A3) and 0.55 g/cm3(A4). There were three types of outer layerof sandwich panel i.e. bamboo strips (B1), jabon plywood (B2), and mahoni plywood (B3). Sandwich panels wereproduced using urea formaldehyde adhesive. The results showed that bamboo-jabon particleboard used as core layerproduced stronger sandwich panels than those using only bamboo particleboards. Bamboo strips as the outer layerproduced stronger sandwich panels than those of using mahoni and jabon plywood. All sandwich panels produced inthis research conform to both the Indonesian Standard and the Japanese Standard requirements for particleboard withveneer overlay.

Abstract

At present, logging activities have implemented Reduced Impact Logging (RIL) technology, but logging waste stilloccurs on average 17%. The logging waste has not been utilized because of the alleged high cost of production due toimproper wood harvesting method. This study aims to obtain data and information on productivity and skidding costsof wood harvesting waste in mountainous natural forest areas. The results showed that the cost of producing woodharvesting waste with the tree-length logging method at ± 2 hm skid distance was Rp 35,693/m3, but when usingthe conventional method is Rp 349,125/m3. The tree-length logging method can not only remove the main wood butalso free from branched wood waste (BBC) and trunk above the branch (BAC) till to landing site but also but it canincrease the efficiency of wood utilization. However, the application of the tree-length logging method resulted in adecrease in logging productivity of 16.47% and skidding of 14.41% at an average skid distance of 3 hm. The averageproductivity of logging in the conventional method is 62.514 m3/hour while the tree length logging method is 52.289m3/hour. The average productivity of skidding tree-length logging method is 17.301 m3/hour but the conventionalmethod is 18.249 m3/hour. For the tree length logging method to be implemented in the field, it is necessary to makechanges in the tariffs for felling and skidding wages following the reduced level of work productivity.

Abstract

This study examined the effect of tree age, trunk position, veneer thickness, and composition of panel core of oilpalm wood on mindi plywood production. Oil palm logs of 1.3 m length were cut from two sources of trees with differentages, i.e. 25 and 32 years old. Four logs were collected from the bottom toward the top of each tree in which ten trees fromrespective age classes were selected randomly and cut into logs. Logs from each age class were peeled in spindleless rotarymachine respectively into two thickness of veneer, i.e. 2.5 and 3.4 mm. Dried veneers (MC 10%) were assembled intotwo kinds of panel, i.e. 3 and 5 plies, where the face and back layer were made using 1.2 mm veneer of mindi (Meliaazedarach) wood. Results showed that trunks from the 32 year old tree have higher green and dry veneer recoveriesthan those of the 25 year old tree. Moisture content and density of the 25 year old panels core are lower than thosemade from the 32 year old veneer. Bonding strength of panels made from the 32 year old core veneer is higher than thatmade from the 25 year old veneer. The 3 layer panels have higher bond strength than those of the 5 layer panel. Panelsmade from 2.5 mm core veneers have lower bonding strength than those made from 3.4 mm veneers.
