THE ABILITY OF TREE IN ABSORBING CARBON DIOXIDE EMISSIONS IN THE CAMPUS OF UNIVERSITAS NEGERI SEMARANG

Abstract

The existence of carbon dioxide (CO₂) in the atmosphere and global temperatures continues to increase. Plants, especially trees, are known as the main regulators of global climate and have played an important role in climate change mitigation. The purpose of this research is to identify the pattern of tree distribution and analyze the absorption of trees against carbon dioxide emissions on the UNNES campus. The research was conducted at the UNNES campus, with mapping units in 8 Faculties and one Postgraduate Campus. Qualitative research was applied in this study with a phenomenological approach. The focus of the study was on tree distribution patterns and tree absorption capacity of carbon dioxide. The results showed that the distribution pattern clustered on the western side of the campus, while the existence of trees on the eastern side of the campus was not as much. Distribution data in faculties and work units showed that the dominant tree distribution was in the Rectorate area with 54 species of trees totaling 4534 trees. Absorption of trees per faculty showed that the largest absorption capacity of trees was in the type of trembles tree, mango, and mahogany that were often found in the Faculty of Sport Sciences with emission absorption of 42% or 2,646,253.41 kg/year. There were many academic activities on the UNNES campus and were supported by electronic equipment.
