Abstract

The accommodation room on the ship is used as a resting place for the crew and as a storage place for goods on the ship so insulation is needed in each room to withstand the heat propagation on the ship. One type of insulation material on a ship is mineral wool which is made from polyurethane. Polyurethane is a plastic foam that is a mixture of polyol and isocynate and one of the ingredients is polymer which can be obtained from natural materials that contain lots of cellulose such as bagasse and sawdust. the addition of sawdust and bagasse that can be done is 40% of the total volume of the mixture. Then it is carried out to get the thermal conductivity value of each mixture of sawdust, bagasse, and polyurethane with various dosing ratios on the sawdust, to further calculate the cooling load. The test results show the best conductivity value is the mixing of wood powder 0.2 gr which is 2.65 w / mk which can withstand the rate of heat up to 311.59 KW.

Abstract

The quality of freshness of fish caught by traditional fishermen must be maintained, one way is by adding coolbox insulation so that it can insulate heat on fishing boats. So far, fishermen use sterofoam as a temperature barrier to maintain the freshness of the fish. The use of sterofoam can pollute the environment. In this research, water hyacinth composite fiber and coconut fiber are used to manufacture coolbox insulation to replace sterofoam as a coolbox insulation material on fishing boats. Water hyacinth powder and dry coconut fibers are mixed into polyurethane with a mass percentage of 40% and 50% which will be compared with pure polyurethare, testing is then carried out to obtain the lowest temperature time and temperature data. The test results show that the percentage of 60% polyurethane and 40% of water hyacinth powder and coconut fiber has an insulation power closer to pure polyurethane with a resistance time of 690 minutes with the lowest temperature of -3 ° C.
