Abstract

During the current pandemic, a means of transportation is needed to support the evacuation of patients through waterways; therefore, PT PAL Indonesia (Persero) has carried out a project called the Hospital Auxiliry Ship. Based on this, to increase productivity in the construction of new ships, a good production process is needed to produce quality ships. The research aims to find out the production system, especially the construction of ship blocks used as objects and waste in the process using the lean six sigma method and the proposed approach to improvement Failure Mode Effect and Analysis (FMEA). The research results with lean six sigma obtained a six sigma value of 3.073 sigma. They obtained the value of Process Activity Mapping (PAM) with the highest percentage of 67.82% in operating activities. The analysis of the causes of wastage using FMEA obtained several factors: block material that is not up to standard, lack of machine maintenance, inadequate surrounding environment, and less skilled operators. Proposed improvements to the defect wastage resulted in improved material inspection, conducting operator training, scheduling machine maintenance, and regularly reworking the defective block construction.
