Abstract

Ambient air as one of an environmental medium require a protection toward pollutant substances that interfere with human health. As an environmental medium, ambient air accommodate oxygen gas, carbon dioxide gas, oxide sulphur, oxide nitrogen, methane, ozone and hydrocarbon produced by human activities as well as from nature. The existence of these gases in the ambient air near at detennined standard wiil not endanger the human being and environment but if the existence of these gases exceed the standard, then will be very harmful to the sustainability of human life and its environment. From CO2 absorption measurement results for 17 plant types that are taken in the experiment, it is obtained that Angsana plant (pterocarpus Indica) has better C02 absorption ability compared with other types. The selection of the Angsana plant (pterocarpus Indica) as a prediction model of green area zone is based on the ability endures toward environmental factor. Model construction of functional relationship between the rate of CO2 absorption and light intensity is an exponential function with the value of R2 (detennination coefficient) of 0.906. Mathematical expression of this model is S = bo exp (b,I), where S : the rate of C02 absorption per leaf width. bo and b1 : empirical constants I : light intensity exp : cardinal number of logarithm natural, i.e. e. Base on measurement of the Angsana absorption rate which intercepts with the light in a range between 50 Wand 150 W, it is obtained that the coefficient of light intensity required on C02 absorption per both width and time units is 0.0048; and Summation constant is 0.2278. Width function respect to the rate of absorption using expression as follows: A=a S = JO.2278exp(O.0048I)dA A=b A=a s' = JO.2278exp(O.0048I)dA A=b Base on the character system, constructed conservation model is expressed as follows: y = bx =d 2.729 exp(O.1719 CO) = S' = J JO.2278exp(O.00481)dxdy y=ax=c
