Defect analysis to improve quality of traditional shipbuilding processes in West Aceh District, Indonesia.

Traditional ships are currently experiencing a significant demand in proportion to the increasing number of fishermen using traditional boats in West Aceh District, Indonesia. However, shipbuilders experienced many obstacles during the manufacturing process, therefore the quality of the ships produced was not in accordance with the standards or the demand of the ship owners. Imperfections in the form of defects on the ship are often found when the ship has been completed. The purpose of this study is to solve the problem of defects that occur in the traditional shipbuilding process in Aceh Barat District, Indonesia. Solving these problems is expected to improve the quality of the ships produced. The initial identification process using Failure Mode and Effect Analysis (FMEA) will be carried out to determine potential defects that can affect the quality of the ship. Defects that pose a high risk to the quality of the ship were resolved using a Logic Tree Analysis (LTA) in order to obtain recommendations for improvements. Based from the results, four risks of damage have been identified that affect the quality of the traditional ships produced, namely; the selection of the quality of raw materials, imperfect wooden joints, easily corroded steel bolts, and poor installation of additional equipment. There are several actions that can be used, among others; replacement of damaged components, reconnection, hot dipped galvanized bolt replacement, and repair the installation of additional equipment.
