Sažetak
Skidding in peat swamp plantation forest requires high skill and alertness, particularly in
relation to peat damage, which includes subsidence as such a damage. The objective of this
research is to analyze the effect of skidding operator’s skill on productivity, skidding cost and
subsidence in peat swamp plantation forest. The method of this research comprised the skidding
operation conducted by two different skidding operators with different working experience,
followed by measuring the average productivity and skidding cost, measuring the elevation of
water table at various points in the peat soil, in the location of logging compartment for 3 years,
namely from 2018–2020 (measured every month), and measuring the effect of working skill
of the two skidding operators on productivity and cost of skidding and the occurring subsidence
rate. Research results show that the average skidding productivity of operator A was
higher than that of operator B due to longer working experience of operator A, which was more
than 5 years. This high average productivity caused low production cost, namely IDR 28,022 m-3
or EUR 1.653 m-3. Wood volume, skidding distance and operators’ skidding skill affect the
average skidding cycle time and cycle time affects the average skidding productivity. Subsidence
in 2018 was higher than that in 2019 and 2020, namely 2.8 cm year-1. Wood skidding
performed by skidding operators with higher skill can increase skidding productivity and
suppress skidding cost.
