UTILIZATION OF BAGASSE AND SAWDUST AS BIO-BASED INSULATION ON THE WALLS OF THE SHIP’S ACCOMMODATION CEILINGTristiandinda Permata, D. Hikmawati, Aurista Miftahatul Ilmah and Jailani
Bagasse has been widely used as an addition of insulation material, it is caused that bagasse contains a lot of lignocellulose which can be processed into artificial boards, in addition to bagasse material which is widely used as an alternative material supporting the artificial board is sawdust so that if the bagasse waste and sawdust used as insulation material, its ability will be maximal as an alternative to making insulation. heat insulation materials are useful in reducing the rate of heat transfer, so the conductivity of these materials must be low. One of the places that use heat insulation is the shipâs accommodation room. One of the shipâs accommodation spaces is one of the parts is the ceiling (the top and bottom of the shipâs accommodation room) is used as a resting place for the crew and as a storage area for goods on board the ship. The process of making insulation materials with the addition of baggase waste and sawdust waste by 40% of the total volume of the mixture consisting of polyurethane. Then the test is carried out to get the thermal conductivity value from each mixture of sawdust, bagasse, and polyurethane with various dosing ratios on wood powders, the cooling load calculation is then performed. The test results show the best conductivity value is the mixing of wood powder 0.2 g which is 2.65 W/mK which can withstand the rate of heat up to 311.22 KW.
