EVALUASI EMISI KENDARAAN BERMOTOR PADA JALAN TOL JAKARTA-CIKAMPEK MENGGUNAKAN MOBILE VERSI 6.2

Edit
ABSTRACT: In  general,  vehicle  emission  in  Jakarta  –  Cikampek  toll  road  increases  from  the  year  2003 to the year 2005, and its predicted to increase continuously. Regression analyses shown that vehicle volume  have  quadratic  regression  correlation  with  emission.  Emission  of  HC,  CO  and  NO x pollutant  have  calculated  by  MOBILE6.2  based  on  vehicle  type  and  used  fuel  type  including  its pressure. It  is  also based on  climate  factors like  air  temperature in area  wide,  altitude, and relative humidity.  Other  factors  that  also  determine  are  average  speed  and  fract ion  of  Vehicle  Miles Traveled (VMT).
 The objective of this research are to calculate quantity of HC, CO, and NOx that produced by  vehicle  volume  across  Jakarta  –  Cikampek  Toll  Road,  to  generate  relation  pattern  between traffic volume and emissions for every section in Jakarta - Cikampek Toll Road, and also predicted amount of emission will be happened in the year 2007. 
 Analysis conducted at every section of Jakarta – Cikampek Toll Road section consist of 13 (thirteen) sections, including Cikampek directio n and Jakarta direction. This is done because every section  have different characteristic that is including vehicle volume factor, vehicle type, and used fuel type. These methods have better R2 value where its compared with method without division of direction and section.
 Hydro  Carbon  (HC) pollutant, at both  Cikampek  and  Jakarta direction  of  year 2003  untill 2005  increases  and  it  prediction  increase  continuously.  HC  pollutant  increases  with  mean  value 14.4 % at Cikampek direction and increasing 12.3 % at  Jakarta direction with R2 mean value 0.964 at Cikampek direction and have R2 mean value 0.967 at Jakarta direction.
For  the  pollutant  of  CO  at  both  Cikampek  and  Jakarta  direction  of  year  2003  untill  2005 increases  and  its  predicted  increase  continuously,  with  mean  increase  9.3%  at  Cikampek  direction and have mean values 9.0 % increase at Jakarta direction. R2 of CO with vehicle number has mean value 0.911 at Cikampek direction and R2 mean 0.935 at Jakarta direction.
Pollutant  NOx  also  increases  for  both  Cikampek  direction  and  Jakarta  direction  of  year 2003  until  2005  experiencing  increase  and  it  predict  will  be  continuing  increase.  These  pollutants have  6.6  %  mean  increase  at  Cikampek  direction  and  6.0  %  at  Jakarta  direction.  R2  mean  value 0.865 at Cikampek direction and have R2  mean value 0.875 at Jakarta direction.
The  result  of  evaluation  MOBILE6.2  emission  factor  against  to  Minister  State  of Environment  Decree  No.141/2003  for  light  duty  gasoline  vehicle  type,  obtained  that  the  emission factor of carbon monoxide, hydrocarbon and nitrogen oxide pollutant, exceed determined threshold. The  light  duty  diesel  vehicles  type,  hydrocarbon  and  nitrogen  oxides  pollutant  below  emission threshold  persistence.  The  medium-duty  diesel  vehicles  and  heavy-duty  diesel  vehicles  type, hydrocarbon, carbon monoxide, and nitrogen oxide pollutant below emission threshold persistence.
