Abstract

Kapal ikan tipe Purse Seine 30 GT milik Dinas Kelautan dan Perikanan Pemda Situbondo dilengkapi dengan sistem pendingin udara untuk mendinginkan ruang palka ikan, dimana tiap dinding ruang palka diisolasi dengan sterofoam. Bahan isolasi tersebut digunakan karena dari segi ekonomis harganya murah tetapi dinilai masih kurang optimal jika dilihat dari total biaya keseluruhan. Dalam Tugas Akhir ini mengoptimasikan ruang palka desain lama diganti dengan alternatif desain baru pada bagian isolasi pendinginnya dengan menggunakan bahan isolasi polyurethane. Dipilih tiga variasi tebal isolasi yaitu 4 cm ( desain A), 8 cm ( desain B), dan 12 cm (desain C). Variasi tersebut digunakan sebagai data untuk menghitung beban pendingin, kemudian dilakukan pemilihan peralatan sistem pendingin. Dari data isolasi dan peralatan sistem pendingin dilakukan perhitungan ekonomis dengan metode Life Cycle Cost yang meliputi biaya investasi, biaya operasional (biaya energi, biaya perawatan dan perbaikan, biaya penggantian) dan nilai harga bekas peralatan (saivage value). Dari hasil perhitungan tiap-tiap desain alteratif diperoleh hasil yang paling optimal berdasarkan nilai Life Cycle Cost-nya adalah desain B dengan keuntungan sebesar 22,98% dari desain lama

The 30 GT Purse Seine type fishing vessel belonging to the Maritime and Fisheries Service of the Situbondo Regional Government is equipped with an air conditioning system to cool the fish hold space, where each wall of the hold room is insulated with styrofoam. This insulating material is used because from an economic perspective it is cheap but is still considered less than optimal when viewed from the total cost. In this final project, optimizing the old design hatch space is replaced with a new design alternative for the cooling insulation section using polyurethane insulation material. Three variations of insulation thickness were chosen, namely 4 cm (design A), 8 cm (design B), and 12 cm (design C). These variations are used as data to calculate the cooling load, then the cooling system equipment is selected. From the insulation and cooling system equipment data, economic calculations are carried out using the Life Cycle Cost method which includes investment costs, operational costs (energy costs, maintenance and repair costs, replacement costs) and the used price of the equipment (saivage value). From the calculation results of each alternative design, the most optimal result based on the Life Cycle Cost value is design B with a profit of 22.98% from the old design.
