Air quality and comfort level assessment: A case of Faculty of Geography, Universitas Gadjah Mada, Indonesia

The aim of this research is to better understand the conditions of air quality, thermal, and audial comfort level in the Faculty of Geography. The measurement of ambient air quality conducted to determine the level of CO (Carbon monoxide) from motors vehicle. Thermal comfort measurement data obtained by measuring parameters of microclimate i.e. temperature, and air humidity, whereas the audible comfort uses noises-parameters. Sample points used to building in the Faculty of Geography. This measurement conducted on 3 days-working hours consecutively from 8 AM until 4 PM during the student orientation week. The result showed that the condition of air quality within the study area based on CO measurement is classified as good air-quality because it fulfills the level standard on all points of measurement. Thermal comfort conditions based on the Thermal Heat Index (HTI) belongs to a less comfortable level and the medium-comfort. The condition of audial comfort strongly affected by the activity on those specific days and also must be considered with the source of noise disturbances from the road (vehicle engine). Therefore, during working days observation there are several sample points that exceed the standard level of noise-standard-quality
