| Summary: | ABSTRACT
The decrease of indoor air quality in building utilizing central air condition could be caused by odour, water vapor, heat and CO2 gas. Besides, it can also decreased due to the decreasing of oxygen content, infiltration of outdoor air and emission from office activities. Improper maintenance could cause central air conditioning system becomes the source of various microorganisms. All these conditions could be dangerous to health. WHO defines Sick Building Syndrome (SBS) as combination of groups of mucous, skin and general symptoms in which each group may only be represented by one symptom.
An observational study was conducted by using cross sectional method on subjects 70 workers in 4 room of PT. PLN (Persero) Unit Bisnis Distribusi Jawa Tengah dan Yogyakarta to find out the possible case of SBS. The parameters of indoor air quality were based on measuring chemical factors (CO, CO2,O2,03 and dust), physical factors (temperature and humidity) and biological factors (microorganism content). The symptoms of SBS were detected by quesionare based on subjective complaint. Data were analyse by using chi square test, Odds Ratio and coefisien contingency.
Indoor air quality measurements shown that chemical factors comply with Threshold Limit Value (TLV), 2 rooms with temperature less than comfort zone, 3 rooms with relative humidity above 70 % and 2 rooms with microorganism of 663 and 644 cfu/m3 more than average. The microorganisms consist of fungi and yeast, Coliform, Staphylococcus and Penicillium. Chi-square test indicated significant different of SBS incident between the respondents working in the comfort zone and in the uncomf ort zone, also on respondents working in room containing microorganism above and less than average ( 498.75 cfu/m3) with the value of X2 = 9.517 at p 0.05.
