Detail Cantuman

The highest of microorganisms suspended in the air were bacteria with a
percentage of 80.8%. If the intensity of bacterial exposure occurs in large
quantities, it will accumulate in the respiratory tract which has the potential to
trigger allergic reactions and respiratory infections. Given the problems and
impacts caused by air microorganisms on public health, it is necessary to monitor
the distribution of air bacteria. The purpose of this study was to determine the
relationship between temperature and humidity with the number of bacteria in the
Manggarai station area. Type of research is correlation. The sampling location is
Manggarai Station, East Jakarta, Indonesia. The 10 sampling points in this study
include the station hall, motorbike parking, prayer rooms, train platform 1-2, train
platform 2-3, train platform 3-4, and train platform 5, toilet, and underpass. The
results of this study included the highest number of bacteria found in the station
hall 331 colonies, the highest percentage of bacterial morphology is monobacilli
was 78%, the distribution of gram positive was more than gram negative with spore
bacteria being more dominant than non spore. The correlation coefficient between
temperature and number of bacterial colonies (0.134) and humidity with number
of bacterial colonies (0.380) showed weak positive correlation, while the
correlation coefficient for light intensity with the number of bacterial colonies -
0.140 (very weak negative)
