Abstract

Sistem pendinginan yang buruk menjadi alasan permasalahan ini yang membuat ikan mudah membusuk dan manusia cenderung membeli ikan yang akhirnya tidak dimasak. Menjaga kualitas ikan dengan penerapan teknologi terbaru menjadi kunci dalam mengatasi permasalahan diatas. Penggunaan kulkas yang dimodifikasi pada sistem pendingin Refrigerated Sea Water (RSW) sangat efektif penggunaanya. Sistem tersebut juga mampu menjaga ikan-ikan tidak saling menempel dan lengket saat disatukan di dalam Portable coolbox sehingga kualitas ikan tetap terjaga. Modifikasi kulkas yang dilakukan yaitu dengan menambahkan kipas, air, dry ice, dan air laut di ruang evaporator pada kondensor serta pemanfaatan panas refrigran dari kompresor untuk superheating. Tujuan penelitian ini adalah mengidentifikasi pengaruh modifikasi kulkas dengan penambahan kipas, air, dry ice, dan air laut di ruang evaporator pada kondensor serta pemanfaatan panas refrigran dari kompresor untuk superheating pada sistem RSW. Metode penelitian dengan melakukan eksperimen dengan skala laboratorium. Variabel bebas yang dilakukan dengan menambahkan kipas, air, dry ice, dan air laut di evaporator pada kondensor serta pemanfaatan panas refrigran dari kompresor untuk superheating pada sistem RSW. Hasil penelitian menunjukan bahwa modifikasi kondensor dengan penambahan es kering sebagai subcooling dapat menurunkan suhu ruang portable coolbox sebesar 10,07 °C dan nilai suhu portable coolbox tertinggi pada kondensor tanpa modifikasi hanya mencapai 13,26 °C pada menit ke-180. COP tertinngi dengan penambahan es kering pada kondensor dimana pada menit ke-180 mencapai nilai 12,88, sedangkan COP terendah terjadi pada kondensor tanpa modifikasi hanya bernilai 6,63. Saat pengujian dilakukan selama 9 jam, suhu air laut pada portable coolbox dengan penambahan es kering pada kondensor dapat mencapai -2,09 °C, sedangkan COP relatif konstan. ====================================================================================================== The worst cooling system is the reason for this problem which makes it easy for fish to rot and humans tend to buy fish that ends up not being cooked. Maintaining the quality of fish by applying the latest technology is the key in overcoming the above problems. The use of a modified refrigerator in the Refrigerated Sea Water (RSW) cooling system is very effective in its use. This system is also able to keep the fish from sticking together and sticking together when put together in the portable coolbox so that the quality of the fish is maintained. The modification of the refrigerator is adding a fan, water, dry ice, and evaporator sea water to the condenser and utilizing refrigerant heat from the compressor for superheating. The purpose of this study was to identify the effect of refrigerator modification by adding fan, water, dry ice, and evaporator sea water to the condenser and the utilization of refrigerant heat from the compressor for superheating in the RSW system. The research method is experiments on a laboratory scale. The variable is adding fan, water, dry ice, and evaporator sea water to the condenser and the utilization of refrigerant heat from the compressor for superheating in the RSW system. The results showed that the modification of the condenser with the addition of dry ice as a subcooling can reduce the room temperature of the portable coolbox by 10,07 ° C and the highest value of the portable coolbox temperature in the condenser without modification was only 13,26 ° C in the 180th minute. The highest COP occurs with the addition of dry ice to the condenser where at the 180th minute it reaches a value of 12,88 , while the lowest COP occurs in the condenser without modification, which is only 6,63. When the test was carried out for 9 hours, the sea water temperature in the portable coolbox with the addition of dry ice to the condenser could reach -2,09 ° C, while the COP was relatively constant.
