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 subsid-ence 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. Subsid-ence 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.
