KAJIAN KUALITAS UDARA KOTA SAMARINDA DITINJAU DARI ASPEK AKTIVITAS KENDARAAN BERMOTOR
ABSTRACT: Declining air
quality and increasing number of vehicles at Samarinda City indicating that
there is strong relationship between both. Research was done to understand
current air pollution level in Samarida as ISPU Criteria and relationship air
pollutant level with number of vehicles activities. Research was done by
counting number of vehicles and collecting air samples at five crowded traffic
intersection. Air samples tested in laboratory for ISPU specified air pollutant
level, which are CO, NO 2 , SO2, O3 and dust (PM 10). Analysis of correlation
was conducted to understand relationship between numbers of vehicles and air
pollutant level. Average level of air pollutant and their ISPU value were CO
2803ug/m 3 (28.03; Good), NO 2 47.9ug/m 3 (-; Good), SO 2 53.0ug/m 3 (33.12;
Good), O 3 31.3ug/m 3 (13.04; Good) and Dust 36.1ug/m 3 (36.1; Good). There was
positive correlation between numbers of vehicles and air pollutant level with
coefficient >0.9. Therefore, limit numbers of vehicles before limit air
pollutant level passed could be predicted. Prediction of limit numbers of
vehicles based on CO level were 31217 units, NO 2 level were 54186 units, SO 2
level were127692 units, O 3 level were 48672 units and dust level were 26371 units.
Levels of CO, NO 2 , SO 2 , O 3 and dust (PM 10) at Samarinda City still comply
PP No. 41 year 1999 with Good as ISPU criteria average. Increase in number of
vehicle will increase air pollutant levels too.
