Abstract

Bamboo is one of non-timber forest products that has been utilized for various purposes. One of its utilizations, as building materials, is in terms of shape and strips. However, with the rapid advancement of gluing technology, bamboo can be used as a raw material for plywood core substitution as veneer. The purpose of this research is to produce a machine strips of bamboo slats with thick uniform size that can be set suit. Before introduced to the stripper machine, bamboo stems must first be cut or thinned into the desired size. The symmetrical bamboo slats are then fed into the thinning machine using a bamboo carrier U-shaped device made of iron that leads to roll clamp. At the last roll, a steel blade is in place to divide and thin the bamboo slats. The upper roll clamp serves to clamp and press the bamboo slats. Rendement the average results of the cleavage 1 (one) sized bamboo rod 8 mm thick, 1.5 cm wide and 30 cm long with a volume of 216 cm3 based on the size of the bamboo strips obtained material thickness of 1 mm by 31.5 cm3 (7 strips) or about 14, 58%,, bamboo strip thickness of 1.5 mm by 74.25 cm3 (11 strips) or about 34.375%, and a thickness of 2 mm bamboo strips as 117 cm3 (13 strips) or approximately 54.17%.Keywords:  bamboo, strip, thinning, machines, knife, motors

Abstract

The total area of oil palm plantations in 2019 is 14.2 million hectares. Every 25 years, there is always oil palm plantations replanting that produced oil palm trunks. The potential of oil palm trunks used as raw material for laminated lumber is about 52.5% of the total of oil palm biomass. Oil palm trunks have a very low density, so that it needs special processing before it could be applied as building material or other uses. The purpose of this study is to analyze the physical and mechanical properties of laminated lumber from oil palm trunks at the end position based on the number of layers. The method used in this research was the utilization of oil palm trunks lamination using PVAc (polyvinyl acetate) adhesive with variations of 1, 2, 3, and 4 layers. The results showed that oil palm trunks could be used as raw material for laminated lumber. The characteristics of laminated lumber made from 1, 2, 3, and 4 layers range between: moisture content (12.16–13.6) %, density (1.281–0.331) g/cm3, MoR (65.46–116.54) kg/cm2, and compressive strength parallel to its fibers (43.31–114,66) kg/cm2. The physical properties of the oil palm trunks laminated lumber with the increasing number of layers tends to increase the density and reduce the moisture content, rather than oil palm trunks laminated lumber with a smaller number of layers. The increasing number of oil palm trunks layers lamination increase the value of laminated lumber mechanical properties.
