Prediction and Modelling of Total Suspended Particulate Generation on Ultisol and Andisol Soil

Total suspended particulates (TSP) are small airborne particles such as dust, fume and smoke with diameters less than 100 micrometers. They are emitted from various sources including power stations, construction activities, incineration and vehicles. Research objective were to analyze the correlation between Total Suspended Particulate (TSP) and wind speed, soil moisture content, and the percentage of land cover on Ultisol and Andisol then modelling of TSP generation prediction. TSP samples were collected by the gravimetric method (SNI19-7119.3-2005). TSP generation correlated positively with wind speed and correlated negatively with soil moisture content and the percentage of land cover. Effect of wind speed on the TSP generation Ultisol was 86.2 % and Andisol was 46.1%. Effect of soil moisture content on the TSP generation Ultisol was 64.8 % and Andisol was 71.5%. Effect of the land cover percentage on TSP generation Ultisol was 84.4 % and Andisol was 92.9%. The TSP generation model for Ultisol was TSP = 22.36 u 4.10 – (-243.26) Ɵ-0.46, with R2 = 0.9692. The TSP generation model for Andisol was TSP = 57.54 u 6.08 – (1.42*109) Ɵ-4.63, with R2 = 0.9578.
