Abstract

Indonesia merupakan salah satu negara penghasil tangkapan ikan terbesar di Asia Tenggara sehingga sektor perikanan memegang peran penting dalam perekonomian nasional. Hasil tangkapan melimpah nalayan sering kali tak berharga jika ikan yang ditangkap busuk sebelum sampai tempat pelelangan ikan. Maka dari itu dibutuhkan sistem pendingin dalam kapal nelayan. Kebanyakan para nelayan memanfaatkan produk es basah sebagai media pendingin. Cara lain yang dapat digunakan dengan menggabungkan antara es basah dan dry ice dengan media portable coolbox. Penambahan dry ice ini dapat memperlama masa mencair es basah, tetapi hanya mampu memperrtahankan dalam waktu singkat. Untuk menjaga pendinginan ikan lebih lama lagi perlu ada penerapan teknologi sistem pendingin terbaru yaitu dapat dikombinasikan dengan Sistem pendingin Refrigerated Sea Water (RSW). Dengan kombinasi sistem RSW dan CSW (Chilled Sea Water) yaitu es basah dan dry ice pada media Portale Coolbox. Metode penelitian dengan melakukan eksperimen dengan skala laboratorium. Variabel bebas yang dilakukan dengan kombinasi perbandingan media pendingin es basah dan es kering pada sistem RSW. Hasil penelitian menunjukan tempertur terendah yang mampu dicapai setiap perbandingan RSW-CSW (es basah dan es kering) dalam waktu 180 menit masing – masing adalah perbandingan 4:0 sebesar 9,7 oC, dengan menggunakan wadah alumunium kombinasi 3:1 sebesar 4,1 oC, 2:2 sebesar -1,5 oC, 1:3 sebesar -0,76 oC. dan dengan dibungkus ice gel kombinasi 3:1 sebesar 2,25 oC, 2:2 sebesar 1,01 oC dan 1:3 sebesar 2,03 oC. Kombinasi es basah dan es kering 2:2 dengan wadah alumunium mencapai temperature terendah sebesar -1,5 oC dalam waktu 180 menit.

Indonesia is one of the largest fish catching countries in Southeast Asia, so the fisheries sector plays an important role in the national economy. The catch of abundant vegetable is often worthless if the caught fish are rotten before they reach the fish auction. Therefore a cooling system is needed in fishing boats. Most fishermen use wet ice products as a cooling medium. Another way that can be used is to combine wet ice and dry ice with portable coolbox media. The addition of dry ice can prolong the melting period of wet ice, but only lasts a short time. To keep fish cooling even longer, it is necessary to apply the latest cooling system technology, which can be combined with the Refrigerated Sea Water (RSW) cooling system. With a combination of RSW and CSW (Chilled Sea Water) systems, namely ice cubes and dry ice on the Portable Coolbox media. The research method is by conducting experiments on a laboratory scale. The independent variables were carried out by using a combination of wet ice and dry ice cooling media in the RSW system. The results showed that the lowest temperature that can be achieved for each RSW-CSW ratio (wet ice and dry ice) in 180 minutes each is a 4: 0 ratio of 9,7 oC, using a 3: 1 combination aluminum container of 4,1 oC, 2: 2 at -1.5 oC, 1: 3 at -0,76 oC. and wrapped in ice gel combination 3: 1 at 2,25 oC, 2: 2 at 1,01 oC and 1: 3 at 2,03 oC. The combination of wet ice and dry ice 2: 2 with an aluminum container reaches the lowest temperature of -1.5 oC in 180 minutes.
