Abstract
Dari 100% energi pembakaran, hanya 30% yang menjadi energi mekanik, sedangkan 40-60% terbuang sebagai panas. Gas buang panas adalah energi yang dilepaskan ke lingkungan dari proses pembakaran. Gas ini dapat dimanfaatkan sebagai sumber energi alternatif untuk meningkatkan efisiensi dan mengurangi konsumsi bahan bakar. Pemanfaatan energi gas buang bergantung pada suhu dan tekanan gas, mulai dari suhu rendah (100°C), sedang (350°C), hingga tinggi (600°C). Dalam industri maritim, panas sisa gas buang dari mesin diesel, turbin, atau generator sering diolah kembali, seperti untuk memanaskan ruangan pada kapal penumpang.Pada penilitian ini menggunakan software HAP 4.9 untuk mengetahui beban pemanasan,Aspen hysys untuk mengetahui performa dan daya heat exhanger yang digunakan.Dalam simulasi perencanaan saluran udara menggunakan software fluid flow untuk mengetahui ducting yang efisien untuk mentransmisikan udara menuju setiap ruangan.Berdasarkan hasil simulasi pada software Aspen Hysys menunjukan bahwa heat exchanger yang dirancang bisa menukar kalor fresh air dari suhu -5°C menjadi 25°C dengan dimensi heat exchanger yaitu diameter shell 740 mm dengan 160 pipa dengan ketebalan 50 mm pada setiap pipa.Sedangkan pada sisi tube memiliki outlet diameter 20 mm dan inlet diameter 16 mm dengan ketebalan pipa 2 mm,panjang sisi tube 6 m.Berdasarkan hasil simulasi pada software Fluid flow menunjukkan bahwa pada setiap sistem ducting memiliki ukuran ducting yang berbeda untuk mempertahankan pressure dan suhu udara pada ducting.Pada sistem saluran udara deck 5F main duct memiliki diameter 400 mm dengan velocity udara 5 m/s.Pada branch duct sisi tengah memiliki diameter 305 mm dengan diameter branch menuju setiap ruangan yaitu 139 mm dan 132 mm dengan pressure drop 0,7 Pa dan suhu udara 23,6°C.Pada sisi atas memiliki diameter branch duct 390 mm dengan diameter branch menuju setiap ruangan 138 mm dengan pressure drop 0,7 dan suhu udara 23,43°C.Pada sisi bawah memiliki diameter branch 176 mm dengan diameter setiap ruangan 90 mm dan pressure drop 1,94 Pa dan suhu udara 23,48°C.Pada deck 6F memiliki diameter main duct yaitu 395 mm dengan branch pada masing-masing sisi atas,tengah dan bawah yaitu 177 mm,370 mm,dan 186 mm.Pada sisi tengah diameter branch setiap ruangan memiliki diameter 139 mm,pada sisi atas dan bawah memiliki branch duct pada setiap ruangan yaitu 90 mm.Pada deck 7F memiliki diameter main duct 257 mm,pada sisi atas,tengah,dan bawah masing-masing memiliki diameter 160 mm,203 mm,dan 160 mm.Pada zona tengah setiap ruangan memiliki diameter branch duct sebesar 53 mm,sedangkan pada zona atas dan bawah pada setiap ruangan memiliki diameter branch duct yang sama yaitu 57 mm.

From 100% combustion energy, only 30% becomes mechanical energy, while 40-60% is wasted as heat. Flue gas heat is the energy released to the environment from the combustion process. This gas can be utilized as an alternative energy source to improve efficiency and reduce fuel consumption. The utilization of flue gas energy depends on the temperature and pressure of the gas, ranging from low (100°C), medium (350°C), to high (600°C) temperatures. In the maritime industry, the residual heat of exhaust gases from diesel engines, turbines, or generators is often reprocessed, such as to heat rooms on passenger ships.In this research using HAP 4.9 software to determine the heating load, Aspen hysys to determine the performance and power of the heat exhanger used.In the simulation of air duct planning using fluid flow software to determine efficient ducting to transmit air to each room. Based on the simulation results in the Aspen Hysys software, it shows that the heat exchanger designed can exchange fresh water heat from a temperature of -5 ° C to 25 ° C with heat exchanger dimensions, namely a shell diameter of 740 mm with 160 pipes with a thickness of 50 mm on each pipe. While on the tube side has an outlet diameter of 20 mm and an inlet diameter of 16 mm with a pipe thickness of 2 mm, the length of the tube side is 6 m. Based on the simulation results in Fluid flow software shows that each ducting system has a different ducting size to maintain air pressure and temperature in the ducting. On deck 5F main duct air duct system has a diameter of 400 mm with an air velocity of 5 m / s. On the middle side branch duct has a diameter of 305 mm with a branch diameter to each room that is 139 mm and 132 mm with a pressure drop of 0.7 Pa and an air temperature of 23.6 ° C. On the top side has a branch duct diameter of 390 mm with a branch diameter to each room 138 mm with a pressure drop of 0.7 and an air temperature of 23.43 ° C. On the lower side has a branch diameter of 176 mm with a diameter of each room of 90 mm and a pressure drop of 1.94 Pa and an air temperature of 23.48 ° C. On the lower side has a branch diameter of 176 mm with a diameter of each room of 90 mm and a pressure drop of 1.94 Pa and an air temperature of 23.48 ° C.On deck 6F has a main duct diameter of 395 mm with branches on each side of the top, middle and bottom of 177 mm, 370 mm, and 186 mm.On the middle side of the branch diameter of each room has a diameter of 139 mm, on the top and bottom sides have a branch duct in each room that is 90 mm. On deck 7F has a main duct diameter of 257 mm, on the upper, middle, and lower sides each has a diameter of 160 mm, 203 mm, and 160 mm. In the middle zone of each room has a branch duct diameter of 53 mm, while in the upper and lower zones in each room has the same branch duct diameter of 57 mm.
