Online published on 13 November, 2019. Abstract The naming of pollutants in the form of particles refers to their physical characteristics or relative size. Dustfall describes large particles that can settle (fall) because it is influenced by its gravitational force. TSP or dust are smaller particles that can float in the air and follow the movement of the wind. PM10 or PM2, 5 are very small particles (equivalent diameter of 10 microns and 2.5 microns) that can enter the human respiratory tract. The existence of these particles is interrelated because they originate from the same source, which is a solid which is mechanically destroyed. Because it comes from the same source and process, the presence of one type of particle under natural conditions will also be followed by the presence of other particles. This makes it possible to estimate the existence of other particles by measuring one of the selected types of particles. This study aims to obtain an estimation model of PM10 and TSP levels through the measurement of dustfall concentration. Dustfall, TSP and PM10 measurements were carried out simultaneously at one coal haul roadside location for 24 hours divided per hour in each measurement set, air temperature humidity measurement, and observation of coal transport volume were also carried out in each measurement set. The results of the study show that; air temperatures ranged from 26–35OC and air humidity ranged from 42–76%, dustfall levels ranged from 676.95–4, 041.14 tons/km2. Month, TSP levels ranged from 153.2–9457.8 μg/m3 and levels PM10 ranges from 145.0–7, 603.4 μg/m3. The particulate matter in the air has a positive correlation with air temperature and has a negative correlation with air humidity. The model of TSP relationship with PM10 was TSP = 0.077 + 1.251 (PM10), the relationship between dustfall and TSP was dustfall = 935, 702 + 305, 333 (TSP), the relationship between dustfall and PM10 was dustfall = 938, 719 + 393, 762 (PM10). It was concluded that there was a relationship between dustfall with the levels of TSP and PM10 individually, and the estimation model PM10 and TSP by the dustfall was a dustfall filled with 60% by TSP and PM10 and TSP filled with 77.8% PM10.
