ABSTRAK

Hasil tangkap laut sangatlah penting untuk kebutuhan pangan. Salah satunya adalah ikan. Untuk memastikan ikan yang dapat di konsumsi adalah ikan yang harus segar. Ikan segar ini menentukan segi kualitas ikan. Kualitas ikan sangat berpengaruh dengan harga jual. Oleh karena itu agar kualitas ikan baik maka perlu mendapatkan penangan yang baik berupa pendinginan. Kesalahan dalam penanganan akan berakibat pada penghasilan nelayan tradisional. Salah satu inovasi untuk mengatasi permasalahan tersebut adalah penggabungan es basah dan nitrogen cair untuk media pendingin. Selain itu cold storage di modifikasi pada bagian dinding dimana tempat gas nitrogen cair menyelimuti dinding. Penelitian ini bertujuan untuk mengetahui Seberapa efektif penggunaan nitrogen cair dan system yang di rancang serta biaya operasionalnya. Dalam penelitian ini didapatkan jumlah es basah yang lebih sedikit yaitu 39 ton es dan 144 kg Nitrogen cair selama 8 hari pelayaran untuk 15 ton ikan. Biaya operasionalnya juga jauh lebih hemat yaitu Rp. 3.300.000 daripada menggunakan Es basah yaitu Rp 5.670.0000


ABSTRACT

Sea product is very important to food demand.for example is fish. To ensure the fish can be consumed it must be fresh. Fresh fish determine the quality aspect of the fish. The quality of the fish is very influent the selling price. Therefore in order to better the quality of the fish it is necessary to get a good cooling treatment. Errors in treatment will result in earnings of traditional fisherman. The innovation to overcome these problems is merging wet ice and liquid nitrogen for cooling media. Besides that the cold storage should be modify on the wall where liquid nitrogen blanketing walls in void space. This study aimed to determine how effective the use of liquid nitrogen and a system designed and operational costs.In this study obtained amount less wet ice which is 3.9 tons of ice and 144 kg of liquid nitrogen for 8 days of sail to 15 tons of fish. The cost is also much more efficient operation of Rp. 3300000 instead of using wet ice Rp 5.670.0000
