Abstract

 In recent years, the increasing amount of plastic waste in many cities in developing countries, including Kupang City, has become a serious environmental problem. The use of plastic waste as a pavement material is one solution to deal with the problem of plastic waste. One type of plastic that can be used as an asphalt mixture modification material is Low Density Polyethylene (LDPE). This research aims to determine the use of LDPE plastic waste modified with AC-WC (Asphalt Concrete-Wearing Course). Five variations of AC-WC mixture were made based on LDPE plastic waste content of 6, 7, 8, 9, 10% based on optimum bitumen content (OBC). Marshall test method was used to determine the OBC and to evaluate the marshall characteristics of LDPE modified AC-WC. The OBC of conventional AC-WC was found to be 5.23% by weight of total aggregate while the ptimum plastic modified bitumen content (OPMBC) of LDPE modified AC-WC was 7.45% by weight of OBC. AC-WC modified with 7.45% LDPE waste had 47.98% higher OPMBC compared to conventional AC-WC

Abstract

Penelitian ini berfokus pada analisis faktor-faktor yang memengaruhi penurunan kinerja lalu lintas di sepanjang Ruas Jalan Timor Raya, khususnya di sekitar Wisata Kuliner Pantai Kelapa Lima. Aktivitas samping jalan, seperti pejalan kaki, parkir kendaraan, dan keluar-masuknya kendaraan, berdampak negatif terhadap kapasitas dan kecepatan lalu lintas, menyebabkan tundaan di ruas jalan tersebut. Metode penelitian melibatkan survei volume lalu lintas, survei hambatan samping, dan survei kecepatan selama empat hari. Hasil analisis data mengindikasikan kapasitas jalan sebesar 1823 Skr/jam dengan volume puncak mencapai 1702 Skr/jam, dan derajat kejenuhan sebesar 0,89. Kendaraan berhenti/parkir di badan jalan diidentifikasi sebagai faktor utama penyebab tundaan lalu lintas. Solusi perbaikan kinerja ruas jalan melibatkan kebijakan larangan parkir di badan jalan, yang diestimasi dapat meningkatkan tingkat pelayanan dari kategori E (arus tidak stabil) menjadi Dj sebesar 0,93, menunjukkan peningkatan signifikan.

Abstract

The massive increase in the number of vehicles has placed a huge burden on urban transport infrastructure. This has created an urgent need for effective strategies to address traffic congestion. In Kupang City, U-turn facilities in the median of major roads such as Piet A. Tallo Street, have become a cause of congestion due to the delays that occur when vehicles make a U-turn. Approaching vehicles are often forced to slow down to allow the U-turning vehicles to merge. In an effort to respond to the growing demands of traffic flow, this study aims to investigate the impact of U-turn facilities on road medians and provide recommendations that can improve the efficiency and smoothness of traffic on urban roads. Using VISSIM software, the simulation of the planned improvement scenario of closing U1, U2 and U3 and diverting them to U4 and improving the geometry of U4 with outer widening was carried out. The results showed that the delay only reached 15.46 seconds/vehicle with level of service C from the previous existing conditions which reached 65.15 seconds/vehicle with level of service F

Abstract

Polyethylene Terephthalate (PET) is a widespread thermoplastic polyester material used daily, especially in producing beverage bottles. Due to its popularity, PET waste is easily available in large quantities from various sources. Previous research shows that PET waste in asphalt mixtures has positive effects, namely increasing the elasticity of asphalt mixtures at high temperatures and improving the stability and stiffness of asphalt mixtures. This research used the Marshall testing method in two phases: Phase I for conventional AC design and Phase II for AC design modified with PET. The results showed that the optimum asphalt content obtained was 6.80%, while the optimum PET content was 4%. At these levels, the AC-BC mixture achieved the best balance between stability, yield, and density and met all the requirements of Bina Marga Specification 2018 Revision 2.
