Abstract

The information about the behavior of the material is indispensable as the decision on
construction material to produce a design that is strength, economical and have a serviceability limit
state requirements. In the construction that using natural materials such as timber, loading position
to the fiber of wood greatly influence the behavior of the material. In granting the compressive force,
the material receives a compressive force parallel to the fiber will have different behavior with
material that receives the compressive force perpendicular fiber of wood. In this research, testing of
compressive strength have been done on Swietenia Mahagoni. The standard test used is the standard
ASTM D143-2002: Standard Test Methods for Small Clear Specimens of Timber: Annual Book of
ASTM standard 4:10 Vol. The test results showed that the average compressive strength parallel and
perpendicular fibers each fiber is 26.76 MPa and 12.37 MPa, so as it can be concluded that the
comparison of the compressive strength of parallel fibers and perpendicular fiber is 1: 0.46 or
compressive forces of perpendicular fibers on the mahogany approximately half of the compressive
strength parallel to the fiber. This can be taken into consideration in the design process on timber
construction.
