Spectral radiation of tree leaves in Bogor Agricultural University campus

Abstract

Every anthropogenic activities that use fossil fuels will produce pollutants such as greenhouse gases. CO2 with other greenhouse gases increase urban air temperatures through the greenhouse effect. The aims of this study are to measure spectral radiation of several species of trees leaves in Bogor Agricultural University Campus and determine types of trees that are effective in absorbing CO2. Data was statistically analyzed based on the order of spectral radiation value. Meanwhile, grouping the ability of species to absorb CO2 was done based on normal curve distribution. Spectral radiation value is inversely proportional to the ability of plants to absorb CO2. The tree species classified as having a high ability to absorb CO2 is Tamrindus indica, Adenanthera pavoniana, Samanea saman, and Ceiba pentandra whereas the species classified as low capacity in absorbing CO2 is Annona murricata, Pterocarpus indicus, Acacia mangium, and Canangium odoratum, the rest classified as having moderate capability.
