Traffic congestion is a common issue in developing metropolitan areas, impacting both economically and socially. Long vehicle queues result in delays for many vehicles, which increases travel time and contributes to deteriorating air quality due to emissions from motor vehicles at intersections. One of the influencing factors is the non-optimization of intersections due to delays. Previous studies commonly use the Highway Capacity Manual Indonesia, 2023, to analyze intersection optimization. However, this study will utilize PTV Vissim software. In planning the intersection, some factors must be considered, such as capacity, density, speed, and type. An average daily traffic survey and a road geometric survey will be conducted in the field survey. The analysis will be performed using PTV Vissim software to optimize the 3 (Three) Talang Buluh intersection in Banyuasin Regency by examining the impact of vehicle queue length and evaluating policies for improving traffic management. According to the analysis results, the data from the First Scenario shows that the maximum vehicle queue length reaches 124.02 meters, with an average delay of 18.75 seconds from the Palembang direction. In the second scenario, installing traffic signal control devices increased the queue length to 287.95 meters from the Betung direction, with the most extended delay reaching 129.52 seconds. The third scenario, which involved geometric changes at the intersection, successfully reduced the vehicle queue length to just 47.70 meters from the Palembang City direction. Additionally, the most extended delay recorded was only 11.59 seconds, demonstrating the effectiveness of this approach, though it is costly and unsuitable for short-term use. Overall, Scenario 1 can serve as a short-term solution for intersection optimization. However, if road widening improvements are feasible, Scenario 3 is the optimal solution for enhancing traffic efficiency and effectiveness, significantly reducing vehicle queues and delays. This is crucial for implementing long-term traffic management strategies at the Talang Buluh Intersection in Banyuasin Regency.

Many recent studies have used plastic waste as an ingredient in conventional asphalt mixtures. However, they did not notice that the addition of plastics can reduce the permeability of asphalt mixtures, which means that porous asphalt is a better plastic trash that will be added to a specific type of asphalt mixture. Despite having a low marshall value, porous asphalt provides a benefit in terms of permeability. Low-density polyethylene (LDPE), a form of plastic trash employed in this study, boosted the Marshall stability mark. This study changed porous asphalt by adding LDPE plastic for usage on the field, then tested for marshall stability and permeability. A porous asphalt mixture should be created as a result of this study's findings with the highest percentage of plastic content without reducing its permeability classification, considering the percentage of plastic used. It is equally essential, and evaluating the wheel tracking machine will help gather more information about its resistance to deformation. The permeability test of porous asphalt with the addition of plastic at 0%, 5%, 10%, 15%, and 20%, respectively, produced findings that were 0.2002 cm/s, 0.1507 cm/s, 0.1131 cm/s, and 0.0897 cm/s. The results of the Marshall stability check on porous asphalt with the percentage of added plastic starting from 0, 5, 10, 15, and 20 percent show values of 571.52 kilograms, 716.9067 kilograms, 731.9467 kilograms, 817.1733 kilograms, and 912 .4267 kilograms. In the wheel tracking machine test, it works well for dynamic stability values at a plastic percentage of 20%, or 7159.091 passes/mm.ABSTRAKBanyak penelitian telah menggunakan limbah plastik sebagai bahan campuran aspal konvensional beberapa tahun terakhir. Namun, mereka tidak memperhatikan bahwa plastik dapat mengecilkan permeabilitas campuran aspal, yang berarti aspal berpori adalah jenis campuran aspal yang lebih baik untuk dicampur dengan sampah plastik. Meskipun aspal berpori memiliki nilai marshall yang rendah, namun aspal jenis ini memiliki keunggulan pada permeabilitasnya. Dalam penelitian ini limbah plastik yang digunakan adalah jenis LDPE (low density polyethylene), yang mana terbukti memberikan peningkatan terhadap nilai stabilitas marshall. Penelitian ini mengubah aspal berpori dengan menambahkan plastik LDPE agar dapat digunakan di lapangan, kemudian dilakukan pengujian stabilitas marshall dan permeabilitas, Hasil penelitian ini diharapkan akan menghasilkan campuran aspal berpori dengan persentase kadar plastik tertinggi tanpa mengurangi klasifikasi permeabilitasnya dengan memperhitungkan persentase plastik yang digunakan. Hal yang tidak kalah penting, dibutuhkan data tambahan tentang ketahanan deformasinya melalui pengujian whell tracking machine. Dari hasil pengujian yang dilakukan, Dengan persentase penambahan plastik pada 0, 5, 10, 15, dan 20 berturut-turut, permeabilitas aspal berpori mencapai 0,2002 cm/s, 0,1640 cm/s, 0,1507 cm/s, dan 0,1131 cm/s, dan 0,0897 cm/s. Hasil dari pemeriksaan stabilitas Marshall pada aspal berpori dengan besaran persentase penambahan plastik mulai dari 0, 5, 10, 15, dan 20 persen menunjukkan nilai 571,52 kilogram, 716,9067 kilogram, 731,9467 kilogram, 817,1733 kilogram, dan 912,4267 kilogram. Untuk nilai stabilitas dinamis pada pengujian whell tracking machine memberikan hasil yang baik pada persentase plastik 20% yaitu sebesar 7159,091 lintasan/mm.
