Indonesia as a maritime country and islands, boats are the only option for people to travel outside the region in order to meet daily needs and usually ships operating from morning to evening with the average shipping time 2-3 hours each way in which ships are generally small so that the engine and the passenger seemed to be in the same room and produce damage to the ear drums. The objectives of this study are knowing noise level and choose proper material for absorbing or dampening noise level. This research using under the provisions of the above then performed experiments to create a Diesel engine casing made from plywood to the outside while the inside is used Polyurethane (PU) and Styrofoam successful minimize noise due to the Diesel engine operation.
