Abstract

Currently, the availability of red meranti, kulim and mersawa wood is commonly used as raw material for “jalur” constructionin Kuansing Regency, Riau Province, are increasingly scarce, while the need is getting higher. Accordingly, it is necessary to choosealternative wood types that have similar strength and durable properties compatible with red meranti, kulim and mersawa wood tomeet specifications for the “jalur” construction. This paper studies the effectiveness of preservative treatment by infusion techniqueand bandage use against dry wood termite. Balam (Macaranga conifera Muell. Agr.) was chosen as alternative wood for makingthe path because currently this wood is abundant but not much used for making pathways. The results of field observations indicatedry-wood termites attacke the path stored on land, so it is necessary to preserve the path so that they are not attacked by wooddestroying organisms, particularly the dry-wood termites. Preservation treatments on standing trees using complex boron compoundsby infusion and bandage techniques were examined to increase the durability class of balam wood. Testing of dry-wood termiteattack was carried out according to the SNI 7207-2014 method. The data were processed using a completely randomized factorialdesign. The analysis results showed that the preservation by infusion and bandage techniques was significantly different in terms ofweight reduction and mortality of termites. Observation on the degree of attack visually on the control and infusion technique was40 (hold) lower than the bandage technique 70 (moderate). The highest mortality in infusion technique was 90.67% compared tocontrol 86.08%, and the bandage was 61.75%. Preservation using the infusion technique showed a higher boron content comparedwith the bandage technique.

Abstract

Timber utilization is mostly affected by wood chemical composition and its natural durability in certain condition. This paper studies chemical composition and under shade natural durability of eight wood species originated from Banten and West Java Provinces. Chemical composition was tested based on Norman and Jenkins’ methods, SNI 140492-1989 and SNI 14-1032-1989 and the wood natural durability test was conducted outdoor under the shade. Result shows that in general wood chemical composition of eight wood species tested is approximately in average of those in broad leaf trees. Among the wood samples studied, the highest holocellulose content was recorded from baros wood (Michelia champaca L.) which was about 75.64% and the lowest holocellulose content was recorded from pasang taritih wood (Lithocarpus elegans Blume Hatus ex Supadmo) which was about 60.19%. In term of lignin content, the highest percentage was recorded from pasang taritih wood, which was about 35.14% and it is comparable with those of ki hiyang (Albizia procera (Roxb.) Benth.) wood, which was about 25.35%. The greatest extractive content was recorded from tarisi wood (Albizia lebbeck (L) Benth), which was about 7.9%, while extractive content nemely tangkalang wood (Litsea roxburghii Hassk) falled into 1.54%. Under the shade durability test showed pasang taritih wood performed second class durability (class II), while the other seven wood species of tarisi, ki hiyang, hanja, cerei, tangkalang, baros, and kapinango were extremly non durable (class V).

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.
