Felling and bucking of rosewood (Darbergia latifolia) related to harvesting productivity in Indonesia

Forest in Java generally is managed by a state-owned company named Perhutani. The most species planted by Perhutani is teak, but in one district in Central Java, Indonesia was planted by rosewood (Dalbergia latifolia) or sonokeling (the vernacular name). We researched harvesting rosewood's productivity in the Pati District of Central Java, Indonesia. The research objectives were to determine the felling and bucking of harvesting productivity and identify the working element of felling and bucking. Also, it analyzed the relationship between the diameter of tree felled related to working time, and the relationship between the amount of lumber in bucking in each log related to bucking time. The result showed that the harvesting productivity of rosewood on average was 2.90 m3/hour. This harvesting productivity was higher than in other locations in Java. In other locations in Java, harvesting productivity was 2.1 m3/hour. We found that an increase in tree diameter felled will increase the felling time, and the amount of lumber in bucking each tree will crease the bucking time. There were six working elements of effective work for felling and five effective working elements for bucking activities. Ineffective time of working element more than 20 % they occurred in bucking activity. The personal delay of the chainsaw operator caused it. This ineffective time can be reduced in order to increase productivity.
