The assessment of wood utilization rate at UD. Karya Lomba Shipyard, Aceh Besar, Indonesia

Abstract

This research aims to analyze the wood utilization rate at the manufacture of the vessel’s frames in UD. Karya Lomba shipyard, Lamteh Village, Peukan Bada subdistrict, Aceh Besar. The study was carried out in March to April 2018 by observing several parameters such as type of wood used, the process of vessel frames making and the utilization level of wood including initial wood volume, the volume of wood used and the volume of unused wood. The descriptive method was done by comparing the volume of wood used with the early wood volume and the volume of unused wood with wood scratch. Vessel’s frames from two under construction vessels were used as the study object by the length of 7.10 m, 13 frames and made from Jackfruit wood (Artocarpus heterophyllus). Then the length of the vessel II with 15.50 m, 35 frames and made from Laban wood (Vitex pubesceus). The results showed that the wood utilization rate for frames manufacturing on the ship I reached 38% and 60% of the vessel II reached 60% respectively.
