Abstract

Nosocomial infection as an infection high morbidity and mortality rates in the world is an infection that is multifactorial in nature. Airborne microbial are the main exogenous source of this infection.

Disinfection technology using ultraviolet is growing rapidly and getting a lot of progress along with the increasing need for the cleaning/sterilization process both in hospitals and offices. The purpose of this study was to prove the effectiveness of the disinfection device using the ultra violet radiation method in reducing the number of airborne microbial on indoors. The number of airborne microbial was counted in the room that was examined using an air sampler, carried our before and after disinfection using disinfection tools. The microbes that grew were counted using a colony counter and the dominant microbes were identified using an automatic Vitek 2^® Compact with a specific card based on Gram stain. A total of 36 disinfection tools were examined in several indoors hospitals and offices in Jakarta. The decrease in the number of airborne microbial range from 26.04 - 96.30% with an average reduction of 58.57%. There were 7 species of microbes in the room before being disinfected, while 3 species of microbes were found in the room after being disinfected. The dominant microbes found in the room before and after disinfection were Staphylococcus epidermidis, Bacillus sp dan Aspergillus sp. To increase the disinfecting power of disinfection tools, it is necessary to pay attention to the dose of ultra violet by considering the area of the room, the light intensity used, the distance of the light source to the microbes, the length of time of exposure and the type of microbe itself.
