Abstract

UNNES has moral responsibility in reducing the decline of green open space in Gunungpati District. Due to the development of Semarang city towards the periphery is by conducting tree planting movements and adding green open space in the campus area. Trees in green open spaces have an important role for environmental quality and human health, but these roles and values have not been widely known because they are considered not to provide direct economic benefits. Regarding this, the assessment of the economic value of trees, especially based on the function of water absorption is necessary. The purpose of this study was to estimate the economic value of trees based on the function of water absorption on the UNNES campuss. The economic value of trees based on the water absorption function is estimated through the calculation of the price of water infiltration by trees and the calculation of stand volume through field measurements of stand parameters, such as diameter, height, and number of trees, which collected from April to September 2018. The results showed that the total economic value of trees based on the function of water absorption on the campus is now around Rp. 49.937/ m2 /day.
