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%
Keywords: greenbelt, CO, Pb,
