World Health Organization (WHO) telah menyatakan kondisi darurat global
terhadap kejadian pandemi Coronavirus Disease (Covid-19) yang menyerang
sistem pernapasan manusia sejak bulan maret 2020. Virus corona tergolong jenis
penyakit menular dan menyebar secara masif ke seluruh penjuru dunia.
Meningkatnya angka persebaran virus Covid-19 di Indonesia mengakibatkan
kebutuhan akan ruangan isolasi dan fasilitas kesehatan khusus Covid-19 juga
semakin meningkat. Ruang isolasi adalah ruang perawatan bagi pasien yang
mengidap penyakit menular seperti difteri, kolera, cacar air, tuberculosis, dan
penyakit menular lainnya baik yang disebabkan oleh virus maupun bakteri. Pada
sebuah ruang isolasi terdapat sistem tata udara yang berfungsi untuk mencegah
adanya perpindahan sumber infeksi ke area lainnya. Dalam merancang sistem tata
udara dibutuhkan perhitungan yang baik dan tepat mengikuti standar Kementerian
Kesahatan Republik Indonesia (KEMENKES RI) dan American Society of Heating
Refrigerating and Air Conditioning (ASHRAE). Metode perancangan yang
dilakukan berupa observasi kondisi ruang isolasi, pembuatan perangkat bantu
perancangan yang mudah dioperasikan, perhitungan beban pendinginan dengan
persamaan CLTDcorr, perhitungan rasio kelembaban, dan perancangan sistem
saluran (ducting) udara. Kondisi ruangan isolasi dirancang pada temperatur 24°C,
kelembaban RH 50%, intensitas penerangan 100-200 lux/m2
, indeks kebisingan
50dBA, perbedaan tekanan antar ruangan 15Pa, dan udara yang di suplai
menggunakan 100% udara bersih. Berdasarkan hasil perhitungan untuk ruang
isolasi bertekanan negatif berukuran 16m2 didapatkan kapasitas mesin
pendinginannya sebesar 33.750 Btu/h (maka pemilihan unit pendingin AC adalah
3,5 PK dengan kapasitas pendingin 34.000 Btu/h) dan jumlah udara suplai yang
dibutuhkan sebanyak 737 CFM

The World Health Organization (WHO) has declared a global emergency against the outbreak of the Coronavirus Disease (Covid-19) pandemic human respiratory system since March 2020. Corona virus is a type infectious disease and spread massively throughout the world. The increasing spread of the Covid-19 virus in Indonesia has resulted in the need for isolation rooms and special health facilities for Covid-19 as well more increasing. The isolation room is a treatment room for patients who infectious diseases such as diphtheria, cholera, smallpox, tuberculosis, and other infectious diseases both caused by viruses and bacteria. On an isolation room there is an air conditioning system that functions to prevent the transfer of the source of infection to another area. In designing the governance system For air, good and precise calculations are needed following Ministry standards Health of the Republic of Indonesia (KEMENKES RI) and the American Society of Heating Refrigerating and Air Conditioning (ASHRAE). The design method carried out in the form of observing the condition of the isolation room, making auxiliary devices design that is easy to operate, calculation of cooling load with CLTDcorr equation, humidity ratio calculation, and system design air ducts. The isolation room conditions are designed at a temperature of 24°C, humidity 50% RH, lighting intensity 100-200 lux/m2 , noise index 50dBA, 15Pa room pressure difference, and supplied air use 100% clean air. Based on the calculation results for space negative pressure insulation measuring 16m2 is obtained by the engine capacity the cooling is 33,750 Btu/h (then the selection of the AC cooling unit is 3.5 PK with a cooling capacity of 34,000 Btu/h) and the same amount of supply air 737 CFM is required
