Analysis of Co Concentration Inside and Outside Minibus at Mangkang Bus Station Semarang

Abstract

ABSTARCT This research uses Mangkang Bus Station as the object of examination. The station is closely related to people-related activities. The CO contents found at the location, based on sampling result from minibus, shows threatening impact due to pollution. The impact does not only apply to the commuters, but also to the passengers as well as the people living nearby the researched location. Object to be used for this research is CO concentration. Sample collection is performed outside and inside the minibus at the parking lot of Mangkang Bus Station to get data on CO concentration. Sample collection stage will be performed seven days in three times, morning, afternoon, and noon. The data used for the analysis are obtained by primary data collection. The research uses a statistically quantitative analysis. Result showed that the content of the concentration on the bus that observed during the study period was 13.086 mg/m3 in the morning, 13.518 mg/m3 during daytime and night time concentrations of CO reached 14.213 mg/m3, so concentration of CO is below than standard. Content of concentration outside the monitored bus during the study period was 17.606 mg/m3 in the morning, 117.202 mg/m3 during daytime and night time concentrations of CO reached 17.488 mg/m3. Such conditions can affect the health of humans in the vicinity and also interfere with breathing. The number of vehicles affects the content of CO produced both inside and outside the bus. The more number of buses around the site, the higher the CO content is in that location, Mangkang Bus Station. Keyword : CO Concentration, Inside, Outside, Minibus, Mangkang Bus Station
