Monitoring air quality systems is important to understand the status of air quality for public health and environment protection. This paper describes the monitoring program for particulate matter pollution that was implemented in 17 urban sites in Indonesia covering Java, Sumatera, Kalimantan, Sulawesi, Maluku and Papua islands. Samples of APM were collected once a week, using a Gent stacked filter unit sampler in two size fractions of < 2.5 µm (fine) and 2.5 to 10 µm (coarse). Nuclear analythical techniques (NATs) such as Instrumental neutron activation analysis (INAA), Particle Induced X-ray Emission (PIXE), X-ray fluoresence (XRF), and X-ray absorption near-edge structure (XANES) have been used in quantification of environmental pollutant. The results showed the annual concentration of PM2.5 in 7 urban sites monitored from Java island exceeded the Indonesian annual air quality standards (15 ug.m-3) and higher compare to other sites. Several elemental composition of PM2.5 have been utilized for source apportionment and identified i.e., road dust, industry, vehicles, biomass burning etc. The national programs of air quality improvement have been resulted in several findings such as lead pollution sources in specific areas in Banten province, heavy metal pollution in east Java, forest fires event in Borneo and Sumatera, and unleaded gasoline program effectiveness. This research also provide a database of air quality in Indonesia, that could be utilized as scientific based reference for government regulation and policy for proper action and strategy to improve the air quality.
