This research aimed to evaluate the durability of Samama (Anthocephalus macrophyllus) wood treated with boron preservatives, citric acid (CA), and heating against termites. Wood samples were impregnated firstly 5% solutions, such as boric acid, borax + combination at 1:1 (w/w). The second impregnation used CA. impregnations conducted in a pressure tank 7 kg/cm2 for 4 hours. After impregnation, heat 80°C or 160°C. All control exposed decay fungi, drywood termites subterranean based on SNI...

Teak is a famous commercial timber; however, many community forests produce low-quality teak from young trees. This research aimed to investigate the effect of heat treatment on dimensional stability and colour wood. Wood samples were pre-dried using fan or in an oven at 40°C. The treatments conducted three temperatures (120, 150, 180°C) for two durations (2 6 h). Water absorption, stability, tests then performed. results showed that density wood slightly decreased after treatment. However,...

Sengon, jabon, and acacia are fast-growing tropical wood species that important for several industries in Indonesia. The purpose of this research was to evaluate the surface roughness wettability some heat-treated, Indonesian species. Surface evaluated using mean arithmetic deviation profile (Ra), whereas determined by measuring contact angle method. subjected heat treatment at 120, 150, or 180°C 2 6 h a small kiln unit. modification reduced moisture content, density, increased properties...

Boron compound had many advantages as wood preservative, but it was prone to leaching. Improving boron preservation required extend the service life of fast growing and low durability red jabon (Antochephalus macrophyllus) hardwood. This study aimed evaluate dimensional stability, color change modified by double impregnation with methyl methacrylate (MMA) heat treatment. Impregnation I used boric acid or borax, II MMA, while treatment temperatures 90 °C 180 for 4 hours. The leachability,...

Relatively little information is available regarding the correlation between wood and veneer quality, especially for Samama wood, an endemic species in eastern Indonesia. This study addresses quality of 8 years old its effect on quality. was determined by evaluating specific gravity, moisture content, fiber dimensions, microfibril angle from pith toward bark. Meanwhile, assessed examining thickness lathe check characteristics. Geometry factor model constructed to elaborate quantities Results...

This study was conducted to analyze the application of boron compounds, methyl methacrylate (MMA), and heat treatment (HT) on changes in density, moisture content, flexural properties samama (Anthocephalus macrophyllus) wood. Samama wood impregnated with borax (BX) boric acid (BA) using a pressure method at 5 atm for 4 h. Afterwards, MMA same duration. Finally, given HT 90 °C 180 °C. The results indicate that there weight gain 93.4% BA monomer Consequently, wood's density increased by 82.3%....

Red jabon wood is a potential fast-growing species for veneer, furniture, and many other products, but its durability very low.
