East Kalimantan has seen an increase in mechanized harvesting methods in recent years. Timber production activities in Surya Hutani Jaya Industrial Plantation Forest, Sebulu District have implemented a mechanical harvesting system, including tree felling activities. In the harvesting system by mechanical means, the presence of felling waste is inseparable. Therefore, the volume of felling waste from stumps, stems, and tree tops was calculated. From the stump waste with an area of 0.25 ha in the research plot, 50 samples were taken with a volume produced of 0.0427 m3 or 0.1707 m3 ha−1. In stem waste, 10 samples were taken with a total volume produced of 0.0453 m3 or 0.1811 m3 ha−1. From the tree top waste, 50 samples were taken with a total volume produced of 0.0374 m3 or 0.1496 m3 ha−1. Waste stump, stem, and tree top waste amounted to 0.5014 m3 ha−1 or 0.45%. The results of this study used the Komatsu PC130F-7, the lowest remaining stump height was 1.7 cm and the highest was 12.6 cm. Meanwhile, the mean stump height is only 5.44 cm. From research, it is known that this company has been able to carry out logging efficiently because the waste produced has a relatively small value. The advantage of harvesting trees with a Komatsu PC 130F-7 equipped with a shearing head is the minimum amount of wood debris that accumulates in the field.
