Skill of Skidding Equipment Operator in Relation to Productivity, Skidding Cost and Subsidence in Peat Swamp Forest Plantation

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