Mahakam river in East Kalimantan has transportation cases that are rarely found in other provinces in Indonesia. The river flow is not only used to serve the public interest but is also used for mining business, one of the most dominant is coal mining through barges. This activity has an impact on the health of the community and the surrounding environment, due to a large amount of dust in the ambient air on the coal transportation route in the river. The purpose of the research was to determine the ambient dust content of the Mahakam river flow crossed by coal transportation and the factors that influenced it. The research method is descriptive which describes the ambient dust content along the Mahakam river which is traversed by barges with purposive sampling measurements. Measurements were taken in the morning at 06.00 – 08.00 and 16.00 – 19.00 WITA because at that time many coal barges were passing. The results showed that the dust content of the river flow that was crossed by barges was 424.8 g/m3 – 58.7 g/m3 for the period from 18.00 – 00.00 and 372.8 ug/m3 – 193 ug/m3 for the period 00.00 – 06.00 WITA.
