Abstract
Pada bulan Maret 2020 WHO menetapkan penyakit Covid-19 sebagai pandemi global. Hal tersebur dikarenakan penyebaran penyakit Covid-19 berlangsung sangat cepat. Pada bulan Maret 2020 jumlah kasus infeksi Covid-19 meningkat tajam dan telah
menyebar ke 187 negara di dunia. Adanya pandemi Covid-19 memberikan dampak buruk terhadap berbagai sektor, salah satunya sektor industri kapal pesiar. Ada 13 kapal pesiar
yang melaporkan adanya infeksi Covid-19 pada kru dan penumpangnya. Penumpang atau kru kapal yang terinfeksi Covid-19 diharuskan untuk melakukan karantina di kapal pesiar tersebut. Namun proses karantina yang dilakukan di kapal pesiar tersebut masih belum memenuhi standar kesehatan yang berlaku baik dalam hal ruang isolasinya maupun sistem ventilasinya. Standar kesehatan yang belum terpenuhi menyebabkan penularan Covid-19 di kapal pesiar menjadi tinggi. Penelitian ini bertujuan untuk melakukan studi
komputasional menggunakan CFD untuk analisa ruang isolasi Covid-19 di atas kapal yang terdiri dari analisa karakteristik dan kinerja aliran udara pada sistem ventilasi serta analisa pengaturan udara yang optimal untuk menciptakan sirkulasi udara terbaik di ruang isolasi Covid-19. Pada penelitian ini akan digunakan metode simulasi
menggunakan CFD, dimana hasil yang didapat berupa karakteristik dan kinerja aliran udara di ruang isolasi Covid-19. Karakteristik dan kinerja aliran udara di pengaruhi oleh letak dari suplai diffuser. Diffuser yang ditempatkan jauh dari posisi pasien akan menyebabkan distribusi aliran udara kurang merata. Selain itu diffuser yang diposisikan dekat dengan sekat ruang isolasi cenderung mengalami turbulensi karena udara yang keluar dari diffuser langsung mengarah ke sekat tersebut dan dapat terjadi aliran udara turbulen. Sedangkan untuk variasi dari exhaust masih belum memberikan perbedaan yang signifikan terhadap distribusi udara di ruang isolasi. Dari variasi posisi suplai diffuser yang telah dilakukan, maka desain terbaik dari beberapa variasi desain yaitu desain dengan jumlah diffuser sebanyak dua unit. Pada desain tersebut memiliki satu titik aliran udara turbulen dan distribusi udaranya juga sudah merata, selain itu desain tersebut juga memiliki kecepatan udara rata-rata 0,022 m/s, perbedaan tekanan sebesar -19 Pa, kelembapan relative 60%, serta suhu 23,5 C.
========================================================================================================================
In March 2020 WHO declared Covid-19 a global pandemic. This is due to the rapid spread of the Covid-19 disease. In March 2020 the number of cases of Covid-19 infection increased sharply and has spread to 187 countries in the world. The Covid-19 pandemic has had a negative impact on various sectors, one of which is the cruise ship industry. There are 13 cruise ships that have reported Covid-19 infections on their crew and passengers. Passengers or ship crews infected with Covid-19 are required to quarantine on the cruise ship. However, the quarantine process carried out on the cruise
ship still does not meet the applicable health standards, both in terms of the isolation room and the ventilation system. Health standards that have not been met have caused
the transmission of Covid-19 on cruise ships to be high. This study aims to conduct a computational study using CFD for the analysis of the Covid-19 isolation room on board
which consists of analyzing the characteristics and performance of airflow in the ventilation system and analyzing the optimal air regulation to create the best air
circulation in the Covid-19 isolation room. In this study, a simulation method using CFD will be used, where the results obtained are in the form of characteristics and performance
of air flow in the Covid-19 isolation room. Airflow characteristics and performance are affected by the location of the diffuser supply. Diffusers that are placed far from the patient's position will cause an uneven distribution of airflow. In addition, a diffuser that is positioned close to the isolation room bulkhead tends to experience turbulence because the air coming out of the diffuser goes directly to the bulkhead and turbulent air flow can occur. As for the variation of exhaust, it still does not provide a significant difference to the distribution of air in the isolation room. From the variation of the diffuser supply
position that has been carried out, the best design from several design variations is the design with two diffuser units. This design has one point of turbulent air flow and the air distribution is even, besides that the design also has an average air velocity of 0.022 m/s, a pressure difference of -19 Pa, a relative humidity of 60%, and a temperature of 23.5 C.
