The Correlation Study of Temperature, Humidity, Lighting and the Quantity of Ambient Air Microorganisms
Background: Air is one of sources of microorganisms, whereas the dust on the air may contain a number of microorganisms. The quantity and the growth of microorganisms are influenced by physical condition of the room such as temperature, humidity, and lighting. This study aimed to determine the correlation between temperature, humidity, and lighting with the quantity of microorganisms in ambient air in the ward of “x” clinic in 2016. Method: The study design was analytic survey with across sectional design. The total samples were six rooms. Data were collected with direct measurements. Data were utilized to figure out the correlation between dependent variable and independent variables using one tailed approach. Result: There was a significant correlation between temperature and quantity of microorganism, the higher of the temperature the higher quantity of microorganism (r = 0,809, p = 0,026). There was also a significant correlation between lighting and quantity of microorganism, the lower of lighting the higher the quantity of microorganism (r = −0,765, p = 0,038). On the other hand, there was no significant correlation between humidity and quantity of microorganisms (p = 0,609). Conclusion: Room temperature were needed to be adjusted to standard condition periodically. Natural lighting from sunshine was necessary to control the growth of microorganisms.
