“…The negative impacts of using heavy equipment logging operations are increasing bulk density, reducing total pore space and infiltration rate, reducing soil permeability and water holding capacity, changes in soil structure, and needing a long time IOP Publishing doi:10.1088/1755-1315/1315/1/012050 2 to be recovered [11,12,13,14]. The level of soil density is affected by the number of passes by the tractor, ground pressure of heavy equipment, tire pressure on the ground, groundwater content, and the tractor's speed [15,16,17]. Soil compaction reduces the growth of natural regeneration and indirectly affects the forest's biomass [18,19,20].…”

Logging operations in natural forests generally use bulldozers. Bulldozers skid logs from the stump site to the landing site. The bulldozer maneuvers in the felling area cause skid trails and soil compaction. Soil compaction is one of the negative impacts of logging operations. The research aim is to analyze the level of soil compaction in various bulldozer skidding intensities after logging operations. The research occurred at a natural forest area in Siberut West Sumatera, Indonesia. The results of the study showed that there was a relationship between skidding intensity and the level of soil bulk density. The more a bulldozer moves at the same skid trail, the higher the soil bulk density. The range of soil bulk density is from 0.82 g cm−3 to 1.31 g cm−3. The bulk density increases markedly after the bulldozer’s first, second, and third passes. After the fourth pass, the bulk density is relatively constant. The porosity of the soil decreases with the increase of the bulk density. On skid trails where the soil is very compact, seeds that fall on skid trails will have difficulty growing well. Requires planting on primary skid trails. Soil damage in the form of soil compaction by bulldozers needs serious attention in the Reduce Impact Logging technique.
