Abstract: PT. X Company is a fishing boat manufacturing company that manufactures boats, speed boats, and sampan types using an order production process. The stages in making a ship include wood selection, determining the size of the vessel and cutting, wood smoothing, ship assembly, unification with glue between wood, and finishing, including smoothing the ship's body and painting. The vessels produced are, on average, 5 - 7.5 meters in size and weigh 500 kg - 2.5 tons with a completion time of 1 month and three months worked on by six workers still using traditional methods. Many workers currently complain of fatigue caused by the length of the shipbuilding process, and the temperature of the production work environment reaches 34o due to the weather. The study was conducted based on problem factors, including physical work environment factors, equipment/machine factors, workload factors, and organizational factors, with the aim of the study to provide suggestions for improving the work system by using the Macroergonomic Analysis and Design approach to increase worker productivity. Workers feel healthier and more comfortable in doing their jobs. The results obtained from the SPSS 23 calculation show that the work environment, equipment and machines, workload, and significant organization have a simultaneous effect because F count (0.00) < F table (0.05 on the work system. The measure of the worker's pulse to reduce fatigue obtained CVL = 37.32%, average rest energy consumption = 2.97 kcal/minute, and an additional 16 minutes of rest time was received at 12.00-13.19, so the total was 79 minutes. Work productivity in measuring and cutting wood produced 16 pieces of ship components per day, so there was an increase in work productivity of 2 pieces of ship components per day.
