Lichen is known as bio-indicators for air quality monitoring. The purpose of this study is to identify the diversity of lichen and response as bioindicators of air pollution. The research was conducted in August until November 2016. The research location is on the campus of the State Islamic Institute Raden Intan Lampung and on the road Soekarno Hatta, Way Dadi, Sukarame, Bandar Lampung. This research is a descriptive study transect method. Based on the research conducted, Species found in the Campus Institut Agama Islam Negeri Raden Intan Lampung totaling 16 species from 8 Family Chrysotricaceae, Graphidaceae, Lecanoraceae, Megalosporaceae, Parmeliaceae, Physiceace, Trypethelidaceae, dan Rosellaceae. The total value of diversity index is 2,61. Then in a comparison study conducted on the Road Soekarno Hatta, Way Dadi, Sukarame, Bandar Lampung totaling 16 species from 5 families, Graphidaceae, Lecanoraceae, Physiceace, Trypethelidaceae, dan Rosellaceae. The total value of diversity index is 1,98. Lichen not only serves as an indicator of air pollutants but knowing the extent of pollution of air pollutants. The worse the air quality, the level of the lower Lichen diversity.
