Air quality monitoring is very important to provide public information about the impacts of air pollution on health, especially in health centers. Particulate less than 2.5 micrometer (PM 2.5 ) is the main parameter of air pollution. This research aims to measure indoor and outdoor PM 2.5 at a women and children’s hospital in West Jakarta. The method for collecting data of PM 2.5 was with a low-cost sensor (LCS), which also collected temperature and humidity data. The LCS was collocated with two ambient air quality monitoring stations (AQMS) as the references. Field measurements at hospital were conducted for three months. The data are statistically analyzed with the openair model. The results show that LCS and AQMS followed a similar trend. Outdoor PM 2.5 concentration is always higher than indoor. Peak hourly outdoor concentrations usually occur around midnight (24:00–03:00). The indoor peak concentrations are between 06:00–12:00. The indoor PM 2.5 tend to be stable, while the outdoor varies throughout the day. The ratio of PM 2.5 concentration (24-hour) indoor to outdoor is 0.8. In conclusion, the relation between indoor and outdoor air pollution is still not comprehensive due to temperature and humidity factors. All indoor and outdoor PM 2.5 are above WHO Air Quality Guideline.
