SIFAT FISIK DAN MEKANIK PAPAN SERAT BATANG PISANG KEPOK (Musa paradisiaca. L) PADA BERBAGAI SUHU DAN WAKTU KEMPA
Abstract: This research aims
to identify the optimal pressing temperatures and time of a fibre board made from
kepok banana stem. The target of density for this fibre board is 0.6 gr/cm3).
The board was made by dividing the fibre into three different parts with the
same weight (weight ration 1:1:1).After that, each fibre was applied adhesive
mixtures by a means of spraying the mixture evenlywith a hand sprayer. Having
evenly mixed, the fibre was put into a 30 cm × 30 cm × 1 cm moldby an
intersecting perpendicular. The physical and mechanical properties were
examined basedon JIS (Japanese Industrial Standard) A 5906-2003. In this
research, the variables ofobservation involved physical properties (density,
water content, thickness swelling, and waterabsorption) and mechanical
properties (MOE, MOR, bonding strength, grasp screw strength).The results
revealed that the averagevalue of physical properties were stated as follows:
the board density was between 0.5618-0.6268 gr/cm3, the water content was
between 9.1438%-10.2041 %, the water absorption was between 148.5961% -
120.5571%, the thickness swellingwas between 15.5167%-23.9611%. Meanwhile, the
average value of mechanical propertieswere recorded as follows: MOE was between
10553.3831 kg/cm2-15199.4095 kg/cm2, MOR was between 208.2067 kg/cm2-270.0940
kg/cm2, bonding strength was between 0.5012 kg/cm2- 1.0790 kg/cm2, grasp screw
strength was between 30.9408 kg - 43.3176 kg. The fibre board with temperature
1800C and 10 minutes of prssing time constituted as the optimal treatment toproduce
a fibre board which met the standard of JIS A 5905-2003 type 5,15,25, and 30.
