Abstract

Currently, 2 (two) infrastructure projects are under construction on the Jakarta – Cikampek Toll Road, they are the Light Rail Transit (LRT) and the Jakarta – Bandung Fast Train. The construction of the project is indicated to be one of the causes of congestion on the road segment. The provision of bus lane (LKAU) on toll roads is one part of the policy package. LKAU which should be used by buses is actually widely used by non-bus vehicles, this certainly affects the performance of roads. To describe the changes in the performance of these roads, it can be measured by conducting traffic simulations. One of the software to perform microscopic simulation is Vissim. Where one of the processes that must be carried out in the software is calibration and validation. This research was conducted to obtain a calibration model that is able to describe the condition of the driver's behavior in the field. The calibration process is carried out by trial and error on parameters including Following Behavior, Lane change behavior, and Lateral behavior. The results showed that the parameter adjustment in the tailing (following), the settings were made by changing the CC0 (standstill distance) value from 1.5 m to 0.50 m, changing the CC1 (headway time) value from 0.9 to 0.5 seconds, changing the the value of CC2 (following variation) from 4 m to 7.5 m and changing observed vehicles movement,lateral namely changing the “desired position at free flow” from the middle of lane to any.

Abstract

The United Nations Environment Program (UNEP) released that 70% of deaths in the Asia Pacific occurred due to poor air quality, including 6.5 million people died in Indonesia. The Indonesian government is committed to achieving net-zero emissions (NZE) by 2030. Responding to this case has made some people think of the best alternative by adding additives to fuel to reduce exhaust emissions released by vehicles. This research was conducted on a Mitsubishi L300 vehicle with diesel fuel. The research method used is an experiment with data collection based on a mixture of 0%, 0.5%, 1%, 2%, and 3% additives. The results of the exhaust emission testing carried out have an effect on the addition of a mixture of additives with diesel. the most significant decrease occurred in the mixture of 3% additives with an average of 25.47% compared to the results of exhaust gas emissions testing on pure diesel (0%). ABSTRAK United Nation Environment Programme (UNEP) merilis 70% kasus kematian di asia pasifik terjadi akibat kualitas udara yang buruk termasuk 6,5 juta orang meninggal di Indonesia. Pemerintah Indonesia berkomitmen untuk mencapai net-zero emission (NZE) pada tahun 2030. Menanggapi kasus tersebut membuat sebagian orang memikirkan alternatif terbaik dengan melakukan penambahan zat aditif pada bahan bakar guna mengurangi emisi gas buang yang dikeluarkan oleh kendaraan. Penelitian ini dilakukan pada kendaraan Mitsubishi L300 dengan bahan bakar solar. Metode penelitian yang digunakan berupa eksperimen dengan pengambilan data berdasarkan campuran variabel zat aditif 0%, 0,5%, 1%, 2%, dan 3%. Hasil pengujian emisi gas buang yang dilakukan terdapat pengaruh pada penambahan campuran zat aditif dengan solar. Penurunan paling signifikan terjadi pada campuran zat aditif 3% dengan rata-rata 25,47% dibanding dengan hasil pengujian emisi gas buang pada solar murni (0%).
