Abstract

Corn stalk (Zea mays L.) can be used as an alternative material in the manufacture of particleboards. However,particleboards made from corn stalks has inferior mechanical properties which could not meet the Japanese standard(JIS A 5908: 2003). Such performance can be improved by adding other material which possesses high strength value,such as bamboo sembilang (Dendrocalamus giganteus Munro). This study examined properties of cornstalkparticleboard which was added into bamboo sembilang fibers in various compositions. Urea formaldehyde and phenolformaldehyde were used as binding agent with 10% adhesive content. Composition of fiber mixtures between corn stalkand sembilang bamboo were set in 100 : 0; 75 : 25; 50 : 50; and 25 : 75. The targetted density of particleboardwas set at 0.80 g/cm3. Mechanical properties of the produced particleboards were evaluated according to JIS A5908:2003 standard. Results showed that particleboard produced using composition of 25% corn stalk and 75%sembilang bamboo bonded with phenol formaldehyde had better mechanical properties than those of the other mixtureraw materials and adhesives. Additional high strength of lignocellulose material such as bamboo is one alternative toenhance mechanical properties of cornstalk particleboard.

Abstract

Commercial biodiesel of oil palm is controversial as the palm oil is classified as food oil and palm plantation utilizesfertile land. One potential type of vegetable oil as biodiesel raw material is kemiri sunan (Reutealis trisperma(Blanco) Airy Shaw) oil. This research aimed to prepare a heterogeneous solid catalyst in the form of an impregnatedSiO2by CaO catalyst (CaO/SiO2), to study the effect of the esterification stage on free fatty acid (FFA) content ofoil, and to test the activity of the CaO/SiO2catalyst during the trans-esterification stage for biodiesel formation. CaO/SiO2catalysts were prepared by sol-gel method made from natural materials (egg shells and rice husk). The FFAcontent of kemiri sunan oil was determined through various esterification stages namely 1; 1.5; and 2 hours in thepresence of H2SO4catalyst. While the trans-esterification stage was carried out under reaction temperature of 60°C,oil to methanol ratio of 1:9, reaction time of 2 hours and CaO/SiO2catalyst content of 3%. The results showed thatthe esterification stage for 1; 1.5; and 2 hours reduced the FFA content from 12.5% (without esterification) to 0.65%;0.58%; and 0.54% respectivaly. Biodiesel made from kemiri sunan oil which was synthesized with the addition ofCaO/SiO2catalyst at optimal conditions of trans-esterification stage fulfilled SNI 7182-2015: Biodiesel based ondensity, viscocity, moisture content, iodine number, and cetane number.

Abstract

Dry wood termites attack is one of the problems that cause huge losses in timber construction. One way to solve thisproblem is by preserving wood, with synthetic chemicals or natural ingredients. The purpose of this preliminary researchwas to determine the effect of ironwood powder extract as a natural wood preservative. Preservation methods conductedwere cold immersion at normal temperature (± 25°C) and hot immersion at 80°C. Variations in the concentrationare 5%, 10%, 15%, and 20%. Variation of immersion time are 1, 2, and 3 days for the cold immersion and 0.5; 1;2; 3 hours for the hot immersion. Results show that mortality data and the degree of attack of dry wood termites. Theresults showed that the mortality of the dry wood termites increased 4−6%. However, no difference was found on thedegree of attacks between preserved and control wood.

Abstract

Wood constructions are mostly fastened by metal screw or metal fastener, then corrosion resistance is an importantfactor. Wood natural durability against fungus and its relation to basic density are two other factors affecting woodquality for construction. This paper studies wood natural durability against fungus and metal corrosion in relation todensity of five Riau wood species. Wood samples were tested against fungus using the Kolle-flask method and wooddensity was measured based on DIN-2135-1975 standard. Result shows that Diospyros korthalsiana wood wascategorized as non-resistant (class IV), Tetramerista glabra wood was classified as moderately resistant (class III),while Shorea teysmanniana, Palaquium burckii, and Aglaia argentea woods are grouped into resistant wood(class II). In all wood species, weight lost of heartwood is lower than that of sapwood, but in the same durabilitygroup (moderately resistant). In general, there is a relationship between density and weight loss. The higher the wooddensity is the lower the weight loss. The average of weight loss of metal screwed wood is higher than wood withoutscrews. The highest weight loss was recorded from Palaquium burckii wood which was screwed and exposed toPolyporus sp., while, the highest screw weight loss was recorded from Shorea teysmanniana wood exposed toPycnoporus sanguineus. Rustic enamel was highly recorded from Tetramerista glabra wood, which was exposedinto Tyromyces palustris. Eight species of fungus are moderate and two species are low in capability of decayingwood. The highest decaying ability in corroding metal screws is found in P. sanguineus. The weight of rustic enamelfound in the metal screw caused by four fungus activity of (Chaetomium globosum, P. sanguineus, S. communeand T. palustris) was relatively similar.

Abstract

Bamboo is a very potential raw material for composite products. However, its susceptibility to moisture and organismsattack limits its utilization. This study examines the resistance of andong bamboo (Gigantochloa pseudoarundinacea(Steud.) Widjaja) particleboard against subterranean (Coptotermes curvignathus Holmgren) and dry-wood(Cryptotermes cynocephalus Light) termites attack. Particleboard with dimension of 35 cm x 35 cm x 1.5cm were manufactured from bamboo waste and it was glued with varying Phenol Formaldehyde (PF) content of 8%,10% and 12%. Specimens were tested according to the Indonesian standard (SNI 7207-2014). Results show thatvariation of PF content influence significantly into the weight loss of particleboard due to subterranean termite anddry-wood termite attacks. The differences of PF content also significantly influenced mortality of subterranean and drywood termites. Particleboard with 12% PF content had the lowest weight losses for subterranean termite (4.34%) anddry-wood termite (0.48%). Termite mortality was escalated with the increased PF content in particleboard. Bambooparticleboard with 12% PF content possessed highest termite mortalities of 71.5% and 76% for subterranean anddry-wood termites, respectively.

Abstract

Various wood producing tree species grows in large forest area of Indonesia. Wood could be used for variousproducts such as furniture, crafts, building constructions and other products like charcoals. Utilization of productsis also generaly associated with physical, chemical, anatomy and mechanics characteristic of wood. This research aimsto determine chemical and extractive composition of five lesser-known wood species from West Kalimantan, namelykumpang, bengkulung, sawang, kempili and ubar wood, and their influences on charcoal properties produced fromcorresponding wood types. The chemical and extractive components of the five wood types were analyzed accordingto the Indonesian National Standard (SNI) method. Each wood species was heated into charcoal through pyrolysismethod with a temperature of 500°C for 4 hours. Results show that the cellulose, pentosan, lignin of these five woodspecies are 51.53−61.16%; 13.93−17.67%; and 26.55−38.46% respectively. The solubility in cold water, hotwater, NaOH 1% and alcohol-benzene are ranged from 0.632−2.640%; 3.28−8.41%; 10.41−19.01%; and3.38−4.3% respectively. Water, ash and silica contents from these woods are respectively ranged from 7.97−9.97%;0.32−2.14%; and 0.21−0.68%. The charcoal products were obtained from five wood types generally have fulfilled theIndonesian National Standard (SNI) requirements with the value of water, ash, volatile matter and carbon contentsare ranged from 0.01−0.69%; 0.59−5.40; 13.95−26.15%; and 73.05−84% respectively. The best quality ofcharcoal was obtained from kumpang wood charcoal.
