| Summary: | The human need for wood is increasing, but the amount of wood supply is
decreasing. In addition, the number of the agricultural products is directly
proportional to the abundance of waste. It is one of the problems in the
agricultural production activities that required attention. The processing and the
utilization of the agricultural waste are expected to be able to solve these issues,
such as the creation of artificial board products, i.e. particleboards. Generally
particleboards use synthetic adhesives that are less environmentally friendly and
renewable, making it necessary to find other alternatives to solve this problem,
namely the chitosan-based adhesives that are derived from crab shell waste.
The main material of this research is corncob waste and natural adhesive
from crab shell. The factor used is the adhesive concentration of 10%, 20%, and
30% and the compression temperature of 160oC and 180oC. This particleboard
manufacturing refers to the process of particleboard manufacturing standards. The
testing products include physical properties (moisture content, density, thickness
swelling, and water absorption) and mechanical properties ( internal bonding,
modulus of rupture, and modulus of elasticity) based on the Japanese Industrial
Standard for particle boards (JIS A 5908 Type-8).
The best properties of particle boards from corncob waste were obtained
from the treatment of 10% adhesive concentration and the temperature of 180oC,
where only the value of the moisture content, density, and internal bonding meet
the standards of JIS A 5908 Type-8, with a value of water content of 10,97%,
density of 0,876 g/cm2, the thickness swelling of 91,249%, water absorption of
161,022%, internal bonding of 2,827 kg/cm2, modulus of rupture of 39,328
kgf/cm2, and modulus of elasticity of 9203,470 kgf/cm2. |
