ANALISIS KEBUTUHAN RUANG TERBUKA HIJAU DALAM MENGENDALIKAN TINGKAT PENCEMARAN GAS BUANG KENDARAAN BERMOTOR

Abstract

The vehicle gas emission pollution at the city is the latent problem. The negative impact is very seriously. Regulation system must be created as a tool to avoid the victim more. Reduction vehicle flow, spatial transportation corridor arrangement and green belt quota regulation do to solve the air pollution problem. The objective of the research is to explore the relationship between pollutant as the dependent variable (Yn) and vehicle flow (X1), space of road corridor (X2) and green belt quota (X3) as the independent variable . The method using is to collect data of Yn, X1, X2 and X3 at the Yogyakarta city. The pollutants indicator are CO, Pb, TSP, SO2 and NO2. By multiple linear regression analyze can be show about the relationship between the variables. The result showing that by pollutant indicators CO (Yco) and Pb (YPb) there are significance correlation grade 96,8% for CO indicator, and 95% for Pb indicator. There is no significance correlation by using TSP, SO2 and NO2 indicator. The result can be formulated: Yco = 11.569 + 5,772 X1 – 11,854 X2 - 19,959 X3 YPb = 0,892 + 0,0000881 X1 – 0,0008603 X2 – 0,002764 X3 Using the regression formula, by using average value of X1 and X2 the CO pollution grade can be reduced under threshold pollution value if the percentage of the green belt more then 6,36%. Pollution of Pb can be eliminated if the the percentage of the green belt more than 16,95%
