Abstract

Pengeringan adalah proses pemindahan atau pengeluaran kandungan air bahan hingga mencapai kandungan air. Permasalahan beban kerja nelayan 2 kali yaitu saat menagkap ikan dilaut kemudian dibawa kedarat dan melakukan proses pengeringan, serta lamanya proses pengeringan ikan saat di darat sehingga penjualan ikan tidak bisa mendistribusikan secara langsung. Sehingga dengan desain system pengering ikan yang langsung ditempatkan dikapal dengan memanfaatkan gas buang mesin induk dari kapal ikan yang bertujuan untuk menguragi beban kerja nelayan pasca penangkapan dan mengeringkan ikan didarat. Pengering ikan dikapal ini dirancang di kapal perikanan 30 GT dengan waktu pengeringan selama 3 jam untuk kapasitas 27 kg dan dikeringkan dari Kadar air 80% menjadi menjadi 30% sehingga Beban pengering didapatkan 1833,15 watt. Dalam perancangan dirancang pula heat exchanger untuk memanaskan udara dari 35 oC menjadi 50 oC dengan Dimensi heat exchanger berdasarkan perhitungan didapatkan panjang = 0,5 m, lebar shell = 30 cm, dengan tube outside diameter = 20 mm, inside diameter = 19 mm. Serta analisa perhitungan back pressure yang telah dilakukan maka yaitu maximum backkpresuure yang diijinkan mesin yaitu286.2 Pa sedangkan backpressure yang terjadi setelah terpasangnya heat exchanger yaitu 59,08 Pa. Secara analisa ekonomi, ikan yang langsung dikeringkan di kapal akan mendapatkan laba yg tinggi Apabila pada 1 kali trip didapatkan viii total teri basah sebanyak 1000 kg total laba per bulannya Rp 86.108.000,-. ================================================================================================ Drying is the process of moving or spending a water content of the material until it reaches the water content. Problems workload 2 times when the fishermen catch fish in the sea and taken on board and drying process, as well as long time of the fish drying process while on the ground so the sale of the fish can not distribute directly. So the fish dryer system design directly placed onboard of vessel with utilizing exhaust gas from a fishing boat that aims to reduces the workload of fishermen after catching and drying fish on land. Ship fish dryer is designed in a fishing vessel 30 GT with drying time for 3 hours to 27 kg capacity and be dryed from 80% to 30% water containt thus obtained Expenses 1833.15 watt dryer. In a well designed to heat air from 35 oC to 50 oC, heat exchanger design with dimensions of heat exchangers based on the calculation, length = 0.5 m, width = 30 cm shell, the outside tube diameter = 20 mm, inside diameter = 19 mm. As well as an analysis of back pressure calculations that have been done so that maximum backkpresuure allowable backpressure engine yaitu286.2 Pa whereas that occurred after the installation of a heat exchanger which is 59.08 Pa. In economic analysis, the fish are immediately dried on the ship will make a profit of eminence If at one time trip obtained a total of 1000 kg of wet anchovy total earnings per month Rp 86.108.000, -
