Abstract:
In 2016, the total area of oil palm plantation in Riau Province was 2,430,508 hectares.
The treatment of oil palm waste from replanting activities via burning and decomposing
may increases the amount carbon emission in the atmosphere which would cause global
warming. This research aims to determine environment-friendly oil palm plantation
management strategies, in particular oil palm trunks waste utilization as alternative staple
source of making plywood core and carbon sequestration. This research took place at PT.
Asia Forestama Raya’s (PT. AFR) factory in Pekanbaru, Riau Province. The data of this
research was taken from 25 years-old replanted Tandum plantation owned by PT.
Perkebunan Nusantara V Ltd. (state-owned) in Riau Province. Ninety one oil palm trunks
were used for plywood core making test material. Based on technical aspect assessment
(mechanical/physics), only 4 mm (three ply) plywood that passed all of the tests: adhesion
shear strength, bonding strength, delamination, and moisture content. Oil palm tree has
223.68 kg C/trunk carbon biomass on average, or 28.63 ton C/ha. Carbon sink on core
plywood was 53.68 kgC/trunk or 6.87 tonC/ha. Carbon dioxide stock -196.82
kgCO2/trunk, or -25.19 tonCO2/ha. The result of this research shows that oil palm trunks
waste which was the biggest waste of replanting activities, could be used as an alternative
timber/base source for plywood core that fulfills technical and also environmental aspects
as carbon sequestration.
