dc.description.abstractLichen have been widely used as bioindicator of air quality. The aims of this study were to know the relationship between certain lichen with traffic volume and influence of traffic volume to lichen diversity and accumulation of Pb and Cr in lichen thalus. There were 20 species from 6 families found from all sampling sites. The highest traffic volume was observed in Jl. Jend. Sudirman, Jl. Arifin Ahmad and Jl. Adi Sucipto respectively. Lichen diversity increased with greater volume of traffic, and was highest at Jl. Adi Sucipto (17 species), Jl. Arifin Ahmad (12 species) and Jl. Jend. Sudirman (11 species). Dirinaria picta was found in all sampling sites and has the highest presence percentage among the observed lichens. The highest accumulation of Pb (4.48±0.18 ppm ) and Cr (1.00 ±0.14 ppm) in D. picta thalus was found at Jl. Jend. Sudirman. The lowest accumulation of Pb (2.03±0.03 ppm) and Cr (0.61±0.13 ppm) in D. picta thalus was found at Jl. Adi. Sucipto. The analysis of Spearmans correlation showed the positive correlation between traffic volume and accumulation of Pb and Cr on lichen thalus at Jl. Jend. Sudirman and Jl. Arifin Ahmad, while negative correlation was shown at Jl. Adi Sucipto. Spearman’s correlation showed negative correlatiom for traffic volume and accumulation of Cr in lichen thalus in all sampling sites.en_US
