| dc.description.abstract | Tremendous increase in the number of vehicle in Binjai City for the last 3 years, as a consequences of
demanding transportation, potentially increase emission load especially on-road transportation
sector, and cause various environmental and health problems. In this study, CO and NOx emission
load estimation carried out using road length approach, emission factor and number of vehicles, four
years emission also calculated, considering the Binjai City medium term development plan (RPJMD)
2021-2026, emission load mapping using ArcGis Software and emission reduction resulting in ASI
(avoid-shift and improve) implementation as synchronizing to the national general energy plan
(REUN), for instance, shifting to mass transportation and the use of the electric motorbikes. The
estimated emission load of CO during weekday and weekend are 1.917,52 – 312.756,54 g/hour and
1.882,53 – 239.543,86 g/hour while NOx accounted in weekday and weekend are 177,75 – 47.809,39
g /hour and 181,29 – 3.863,63 g/hour. Based on the projected results with vehicle growth of 17%, CO
emission loads on weekdays and weekends are 3.590,03 – 585.551,25 g/hour and 3.524,52 –
537.970,33 g/hour while for NOx it is 332,78 – 89.510,04 g/hour and 339,42 – 69.017,08 g/hour. The
mapping results show that the highest CO and NOx emission loads are on primary arterial roads,
namely Jalan T.A Hamzah and Jalan Soekarno Hatta. The application of the specified scenario in the
form of shifting to mass transportation can reduce CO emissions by 22-24%, but fails to reduce NOx
emissions. While the scenario of switching to electric motorcycles is able to reduce the emission load
for both CO and NOx by 5% and 1%. | en_US |
