Indoor air pollution in air-conditioned bus and non-air-conditioned bus

Abstract

The use of buses as mass transportation mode has become a popular option for the people because of the cheap price and flexibility. The bus comfort is one of the keys to improving the quality of transportation service. However, the bus capability to carry many people with various conditions has a potential risk of creating indoor pollution inside the bus. This study aims to examine the level of air pollution inside an air-conditioned bus and a non-air-conditioned bus with a biological agent's approach as the source of pollutants. The analysis conducted in this study is limited to microorganisms as one of the sources of indoor air pollution. Several media are placed in some part of the air-conditioned bus and non-air-conditioned bus. The study shows that there are fungi inside the buses that serve as contaminants and pathogen microbes that can cause air pollution.
