PEMBUATAN MODEL SEDERHANA PENGARUH GAS CO2, SO2 DAN NO2 TERHADAP TINGKAT KEASAMAN AIR HUJAN

Abstract

Simple model has been created using effect of CO 2, SO and NO on the level of rain water 2 2 acidity (pH). Measurement of gases (CO 2, SO and NO2) are conducted using continuous 2 monitoring program. CO is measured by Picarro G1301 analyzer with CRDS method, NO2 2 is measured by TS42-TL analyzer with Chemiluminescence method, while SO gas is 2 measured with TS43i-TLE analyzer with UV Fluorescence method.Three kinds of gas make 7 different scenario models. The amount of the influence of CO , SO and NO is calculated, 2 2 2 then acidy result from calcutation compared with its observation. Pearson correlation value is used as an indicator of an appropriate selection of model scenarios. The results show that acidity level of rainwater in GAW Bukit Kototabang Station in April 2009 was influenced by a mixture of CO and NO gases, in May 2009 was affected by CO alone, in June 2009 was 2 2 2 influenced by a mixture of CO and SO gas.The Data of acidity level of rain water in April, 2 2 May and June 2009 compared with this model confirmed that air condition in environment around of Bukit Kototabang GAW Station still cleanness.
