Abstract

Abstract In the city of Makassar, Polyalthea Longifolia plant is used as one of the plants absorbing CO2. Towering form, leaves lush and green despite the dry season it is interesting to be used as an ornamental plant roadside. CO2 is one of the greenhouse gases, and it is the main element of the photosynthesis process, that is the reason we use plants as a tool to reduce air pollution. The beauty of Polyalthea Logifolia plant as an ornamental plant roadside and as an absorber CO2 are the main reasons to put it along the highway, but we observed the ability of leaf in absorbing CO2 was only less than 1 %.
