KUALITAS MIKROBIOLOGIS UDARA DI SALAH SATU PUSAT PERBELANJAAN DI JAKARTA SELATAN

The airborne bacteria and fungi in parking building, playground and food court in Blok M Square,
South Jakarta, were assessed in order to investigate air quality in one of the shopping center in
Jakarta. The air sample was passed through plate count agar and potato dextrose agar using a
single-stage multi-orifice Sampler SKC Biostage Standard. Results showed that average microbial
concen-trations were 200.17, 101.17, 55, 33 CFU bacteria per m3
, and 109.54, 37.69, 27.09 CFU
fungi per m3
of air volume in the parking building, the children playground and the food court,
respectively. The most dominating bacteria had characteristicsresembleairborne Bacillus subtilis,
while the most dominating fungi wereidentified as Cryptococcus sp., Aspergillus spp., Penicillium
sp. and Candida sp. The microbial concentrations were different significantly (α=0,05) inall the
three areas. In addition, there were strong relationship and significant influence between the
concentrations of bacteria and fungi to temperature, humidity and light intensity in in all the three
areas based on Pearson correlation analysis. For today, there is no air quality standard
specifically for shopping center, so the data were compared tocommon standards for indoor air
quality. The concentration of bacteria and fungi met the standard regulated by TheMinistry of
Health Republic of IndonesiaNo.1405/MENKES/SK/ XI/2002 about Environmental Requirements
for Office and Industrial., i.e <700 CFU/m3
, and acceptable according to World Health
Organization (WHO) with 500 CFU/m3 as a normal condition. In any case, it is advisable to be
aware ofthe spread of airborne bacteria and fungi in shopping centersthat are potentially
pathogenic.
