      Abstract
      Sistem pemanenan pada tegakan jati menggunakan short wood system yaitu log diangkut keluar hutan dalam bentuk potongan log yang sudah bersih dari cabang dan ranting. Oleh karena itu, kegiatan pemotongan cabang (delimbing) perlu dilakukan dan menjadi kegiatan yang menentukan produktivitas kerja. Kegiatan delimbing harus dilakukan dari arah pangkal pohon sampai ke ujung pohon untuk alasan keselamatan. Namun, yang terjadi di lapangan sering kali delimbing dilakukan secara acak. Penelitian ini bertujuan membandingkan kinerja kegiatan delimbing yang dilakukan secara berurutan dengan delimbing yang dilakukan secara acak dengan pendekatan produktivitas kerja. Penelitian ini menggunakan video rekaman kegiatan delimbing dan menganalisisnya dengan metode time study. Produktivitas kerja diperoleh dengan mempertimbangkan faktor kelonggaran yang berkaitan dengan penggunaan tenaga manusia pada perhitungan waktu standar. Penelitian ini menunjukkan bahwa delimbing yang dilakukan secara berurutan memiliki produktivitas yang lebih besar yaitu sebesar 6,506 pohon/jam, sedangkan produktivitas kerja delimbing yang dilakukan secara acak diperoleh hasil sebesar 5,142 pohon/jam. Delimbing yang dilakukan secara acak mengakibatkan lamanya tambahan waktu kerja yang diperlukan untuk berjalan, karena arah berjalan seringkali melewati rute yang sama beberapa kali. Kata kunci: acak, berurutan, kelonggaran, pemanenan hutan, produktivitas kerja
       
      The harvesting system in teak stands utilized the short wood system, where logs are transported out of the forest as pieces that are already clean from branches and twigs. Therefore, branch cutting (delimbing) needs to be done and is an activity that determines work productivity. Delimbing activities must be carried out from the base of the tree to the end of the tree for safety reasons. However, what happens in the field is often delimbing done randomly. This study compares the performance of delimbing activities carried out sequentially with those carried out randomly with a work productivity approach. This research uses video recordings of delimbing activities and analyzes them using the time study method. Work productivity was obtained by considering the allowance factor related to the use of human labor in calculating standard time. This study shows that sequentially delimbing has a greater productivity of 6,506 trees/hour. While the productivity of delimbing work done randomly obtained a result of 5.142 trees/hour. Delimbing that is done randomly results in additional work time required for walking, as the walking direction often passes the same route several times. Keywords: allowance, forest harvesting, random, sequential, work productivity
