SIFAT FISIK DAN MEKANIK BATANG KELAPA SAWIT (Elaeis guineensis Jacq) BERDASARKAN PADA POSISI KETINGGIAN BATANG
Abstract: The research aims to
determine the physical properties (moisture content, density and dimensional
stability) and mechanical properties (modulus of elasticity, modulus of
rupture, and modulus of crush stiffness) of Elaeis guineensis Jacq based on the
position the trunk). The design used in the study was a completely randomized
design (CRD) with 3 replications and the factor is the position of the stem
height (low, middle, and top) of oil palm (Elaeis guineesis Jacq). The results
showed that height position have significant value to moisture content, MOR and
MCS, but did not significantly affect the value of density, dimensional
stability and MOE. The moisture content value was range from 38,49 % - 101,07 %,
and the density value was range from 0,46 gr/cm3 – 0,62 gr/cm3, meanwhile the
dimensional stability value was range from 11,54 % - 19,84 %. The modulus of
elasticity value was range from 4456,77 gr/cm2 – 10062,40 gr/cm2, and modulus
of rupture value was range from 108,20 gr/cm2 – 354,47 gr/cm2, meanwhile the
modulus of crush stiffness value was range from 16,56 gr/cm2 – 69,96 gr/cm2.
The research concluded that oil palm trunk in the low position have physical
and mechanical properties better than in the middle and top, and enroll in
class V of strongness and suitable for use as raw material for particle board
or other composite products.
