SIFAT FISIK DAN MEKANIK KAYU BENUANG (Octomeles sumatrana Miq) YANG DIDENSIFIKASI BERDASARKAN SUHU DAN WAKTU KEMPA
Abstract: Benuang (Octomeles
sumatrana Miq) wood less attractive to industrial carpentry, because of Benuang
wood has a low at strength level (strength class IV - V). Densification of wood
is one solution, which is the timber compaction process that aims to improve
the strength and durability of the wood. There are two factors for treatment in
this study that include temperature factors felts (1700C, 1800C and 1900C) and
Time Felts (50 minutes and 60 minutes). Samples made ??of from Benuang with
wood measuring 30 cm (L) x 8 cm (W) x 4 cm (H), then steamed in an autoclave
and hot pressed (hot press) with a target thickness of 30% and the pressure
felt by 60 kg/cm2. Then created a test sample for testing. The parameters
measured are physical properties (color and touch wood impression, moisture
content, density and dimensional changes) and mechanical properties (static
bending persistence / Modulus of Elasticity, strength of bending fracture /
Modulus of Rupture, and firmness press parallel fiber / Cruishing Maximum
Strength). The design that used in this study is a 3x2 factorial experimental
design in a completely randomized design (CRD) with 3 replications. Results
showed that the densification process on wood Benuang generally not been able
to increase the strength of the timber, that is still in the same class with
the timber control (strenght class IV-V). But partially strength there is still
best value that on the showed densification timber with temperature 1800C with
clamp time for 60 minutes, with decrease in water content of 43.12%, increase
in value density of 27,22%, dimensional change impairment of 7,57%, MOE
impairment of 71,61%, MOR values ??decrease by 61,93% and MCS impairment of
18,41%.
