The purpose of analyzing the number of airborne germs with the incidence of Covid 19 cases at KKP Semarang. This study is an observational study by measuring the physical quality of the air in the research location and taking air samples to calculate the number of germs in the air in the room. The results of this study that the number of airborne germs is influenced by factors such as temperature, humidity, and lighting. The use of ventilation systems (using air conditioning or fans) will also affect the development of microorganisms in the room. Efforts have been made to control the development of airborne germs in the room, including the placement of a humidifier, maintenance of air conditioners/fans, and the obligation to use PPE (masks) in the room to minimize the transmission of Covid 19 during activities.
