Abstract

Increased production of Indonesia catch fish accompanied by increased coolbox using to maintain freshness of fish. The efforts to maintain freshness of fish during this time is use a coolbox made from styrofoam which is not environmental friendly. Therefore, it is need to make cool box with environment friendly material and also effective for fish preservation . In this research, coolbox is modified with insulation based on Sengon wood sawdust (Paraserianthes falcataria (L.) Nielsen) and rice straw. Using the sawdust of sengon wood and dried straw pieces , experiments conducted to get the best composition of insulation, insulation variated with 2 different adhesives, PVAc and polyurethane .The results of the density test and thermal conductivity test, also in terms of preparation of various insulation variations, show that insulation with 66% sawdust of sengon wood; 28% straw; and 6% polyurethane adhesive is the best insulation to be used in coolbox, with thermal conductivity of 0.54 W / mK and density of 0.38 gr / cm3. The experiment in coolbox is done for 24 hours with 48 times data retrieval. Used ice cubes with a mass of 2.0 kilograms and 400 grams tuna fish. The experimental results show the minimum temperature that can be achieved coolbox is -0.1 ° C below the surface of  ice .In fish body, the lowest temperature that can be achieved is 3, 2 ° C. While in the coolbox room, the lowest temperature is 19.4 ° C. The results also show coolbox with sengon sawdust and rice straw  insulation able to preserving fish for 15 hours, with weight ratio between fish and ice is 1: 5.
