Pengaruh Dimensi Cacat Kayu Terhadap Penurunan Kekuatan Struktur Gading Gading Kapal
This research was conducted in August 2020. The specimens were made at
the Port and Ship Laboratory of the Department of Fisheries Resources
Utilization, Faculty of Fisheries and Marine Affairs, Riau University. Then the
specimen testing was carried out at the Materials Testing Laboratory of the
Department of Mechanical Engineering, Bengkalis State Polytechnic. The purpose
of this study was to determine the effect of variations in the diameter of wood
defects on the addition of wood strength. This method is an experimental method
by making specimens from wood specimens without lamination and with
laminates with knots on the wood surface. Bending test using Gotech Testing
Machines INC model GT-7001-LC 30.
For the compression test parallel to the grain for non-deformed leban wood
that is not coated with fiberglass, it has the highest value at maximum load with a
value of 1393.42 N on the 1st test specimen, deformation with a value of 4.56mm
on the 1st test specimen, and stress with a value of 1086.86 Mpa. on the 1st test
specimen. For the compression test parallel to the grain for non-deformed leban
wood covered with fiberglass, it had the highest value at maximum load with a
value of 1749.65 N in the 2nd test specimen, deformation with a value of 6.63mm
on the 4th test specimen, and stress with a value of 696.28 Mpa on the 2nd test
specimen. For compression testing parallel to the grain for defective leban wood
not covered with fiberglass, it has the highest value at maximum load with a value
of 752.91 N on the 4th test specimen, deformation with a value of 3.55mm at the
4th test specimen, and the stress with a value of 587.26 Mpa on the 4th test
specimen. For the compression test parallel to the fibers for deformed leban wood
covered with fiberglass, the highest value was at maximum load with a value of
1003.73 N on the 4th test specimen, deformation with a value of 6.51 mm on the
3rd test specimen, and stress with a value of 399.44 Mpa on the specimen. 4th
test. So it can be concluded that the higher the maximum load value in the
compression test parallel to the fiber, the higher the stress value will be and if the
lower the maximum load is given, the higher the deformation value will be.
