Arboretum as one example of ecosystems that have the diversity of flora
and fauna requires good management, so as to provide benefits to the
surrounding environment. Biological diversity (biodiversity) that exist in the
Arboretum area is quite high. This is because the Arboretum has many species
which are usually brought in from outside, then planted and maintained as a
collection of plants for various purposes of academic activities, in addition to
local species that live naturally in the Arboretum.
Limited funds arboretum management and level of understanding about the
functions and benefits of some of the arboretum, arboretum resulted in the
existence of a very minimalist. This issue will greatly affect the existence of the
arboretum in the future.
The purpose of this study are aware of the economic value of the existing
flora and fauna in the Dipterocarpaceae arboretum and get the benefits of
environmental services for the around arboretum.
Economic valuation of the timber is done by using the market price
approach. To obtain economic value of wood made a simple calculation that the
total timber volume multiplied by price per unit of wood. While the economic
value of air services is divided into two parts namely the absorption of carbon
dioxide by the market price method and coolness by using surrogate price
method.
Value of economic in Unilak dipterocarp arboretum of Rp.
15,538,672,849.13 consisting of timber economic value of Rp. 385,843,912.00
and the coolness of the economic value of Rp. 15,137,500,000.00 and carbon
uptake value of Rp. 15,078,937.13. The economic value of benefits in the form
of services (intangible) greater (97.52%) than the value in the form of objects
(tangible) (2.48%).
