Abstract

Virus Corona (Covid-19) menjadi perhatian khusus karena penyebarannya yang cepat ke seluruh dunia dan menyebabkan okupansi rumah sakit menjadi sangat tinggi. Sehingga perlu dilakukan pemodelan pada ruang isolasi pasien Covid-19 untuk menginvestugasi aliran udara serta keefekitfan aerosol sanitizer yang menggunakan AC untuk melindungi para tenaga medis dan meminimalisir persebaran virus Covid-19. Dengan menggunakan Solidworks, dilakukan pemodelan pada masing-masing ruang isolasi pasien (9144 mm x 6096 mm x 3658 mm) berupa Pintu (1234 mm x 1066 mm), exhaust vent (1800 mm x 300 mm), AC vent (1000 mm x 1000 mm). Kasur (1219 mm x 1828 mm x 2134 mm) dimodelkan dan divariasikan pada 6 ruangan, dimana Ruang 1-3 masing-masing berisi 2 kasur, 3 kasur, dan 6 kasur tanpa mesin sanitasi. Sedangkan Ruang 4-6 masing-masing berisi 2 kasur, 3 kasur, dan 6 kasur dengan mesin sanitasi (1524 mm x 1328 mm x 1219 mm). Kemudian untuk simulasi Ansys, Meshing secara tetrahedral dan hexahedral dilakukan serta kondisi batas dimasukkan. Untuk kondisi inlet AC, temperaturnya seragam sebesar 24 oC dengan kecepatan sebesar 3,91 m/s. Sedangkan kondisi mesin inlet sanitasi, temperaturnya seragam di 30 oC dengan kecepatan inlet sebesar 1,5 m/s. Setelah dilakukan simulasi pada Ansys, didapatkan bahwa ruangan dengan varian 6 kasur dengan mesin sanitasi, memiliki nilai turbulen energi kinetik terbesar, dengan nilai 2,19 m2/s2 .Turbulensi energi kinetik yang tinggi di ruang isolasi membuat persebaran campuran udara sanitasi dan AC menjadi rata ke segala penjuru ruangan, sehingga semakin tinggi nilainya maka akan semakin bagus.

Coronavirus disease (Covid-19) became an attention because the virus spread rapidly all over the world. Hospital occupancy became high due to high case each day. Hence, modeling and simulation in the Covid-19 isolation room needed to investigate the airflow inside the room and the effectivity of aerosol from sanitizing machine with Air Conditioner to protect doctor, nurse, and minimizing the virus spread. Solidworks was used for room design, the patient room (9144 mm x 6096 mm x 3658) is modelled with Door (1234 mm x 1066 mm), exhaust vent (1800 mm x 300 mm), AC vent (1000 mm x 1000 mm) in each room. Beds (1219 mm x 1828 mm x 2134 mm) were the variations and modelled at 6 rooms in total. Room 1-3 contained 2, 3, and 6 beds respectively without sanitizing machine. Room 4-6 contained 2, 3, and 6 beds with sanitizing machine (1524 mm x 1328 mm x 1219 mm). Tetrahedral and hexahedral meshing were needed and after that inserting inlet condition as the boundary condition. Boundary condition of AC: Uniform temperature at 24 oC, velocity 3.91 m/s. Inlet condition for sanitizing machine: Uniform temperature at 30 oC, velocity 1.5 m/s. It was known that the room with configuration of 6 beds with sanitizing machine has the biggest turbulence kinetic energy, with the value of 2.19 m2/s2. When the turbulency value was high, the flow of mixing air from AC and aerosol spread to all of the room, so the isolation room is fully sanitized so the room free of virus and flatten the curve.
