KORELASI ANTARA RUANG TERBUKA HIJAU DENGAN KONSENTRASI KARBON DIOKSIDA (CO2) DAN OKSIGEN (O2) DI KAMPUS UNIVERSITAS EFARINA PEMATANGSIANTAR

Abstract

Green Open Space (RTH) is an elongated area/lane and/or clustered, whose use is more open, where plants grow, both those that grow naturally and those that are intentionally planted. The provision of green open space in a city is at least 30%. Green open space on the Efarina University campus is included in private green open space. The results of the ANOVA regression correlation analysis between green open space (X) and CO2(Y1) on the Efarina University campus yielded sig. 0.034 <0.05 with a 95% confidence level, and the results of the ANOVA regression correlation analysis between RTH and O2 yielded sig values. 0.003 < 0.05 with a 95% confidence level. The results of the analysis show that there is a correlation between green open space with CO2 and green open space with O2. The total area of ​​green open space that must be added on the Efarina University campus for the next 5 years, namely in 2023 is 1.9 hectares. Increasing the number of trees to reduce CO2 concentrations can be done by selecting tree species first. Species that are able to absorb CO2 and can be used as green open space planning for the next year. Tree species that can be used for planning green open space for the next 5 years at the Efarina University campus are sono trees, trembesi trees and Bungur trees.
