Nilai Ekonomi Arboretum Sylva Universitas Tanjungpura Pontianak (Economic Value of the Sylva Arboretum of the Tanjungpura University Pontianak)

Sylva Untan Arboretum has high biodiversity. However, these values and benefits are not yet known by many parties, hence the existence of the Sylva Untan Arboretum could be changed. The purpose of this study was to determine the economic value of the Sylva Untan Arboretum. The study was conducted using a survey method. Primary data was collected through observation and interviews, while secondary data was collected from various literature. The economic value was calculated using three methods, namely the market price method, substitution cost method, and contingency method. The data were analyzed using an analysis of total economic value. The results showed that the economic value of Sylva Untan Arboretum was IDR 15.346.872.680 per year. Economic value in the form of service benefits (intangible) was higher than the tangible value. The measurement of the economic value of Sylva Untan Arboretum can be done using other approaches and methods that are more holistic as a comparison of existing economic values especially for several values, such as biomass value, water absorption, and land rent. The measurement of the economic value of the Sylva Untan Arboretum needs to be developed to make a positive contribution to the people living around it, as well as decision making in land use.Keywords: arboretum, benefit, ecosystem, economic valuatio
