Abstract

Traffic performance refers to the evaluation of the service quality of a road segment relative to the traffic flow through it. Road traffic performance assessment is measured by the degree of saturation and travel speed. Road capacity (C) is the ability of a road section to accommodate traffic flow in a certain time unit. Road capacity is influenced by the type of side obstacles and the frequency of occurrence. This research was conducted on Jalan Jenderal Ahmad Yani Campus A, Muhammadiyah University of Palembang to calculate road capacity (C) and traffic performance on Jalan Jenderal Ahmad Yani.  Data analysis was carried out using the 2023 Indonesian Road Capacity Guide where road capacity and degree of saturation are road traffic performance parameters so that the value of the level of service is known. Based on the results of research and analysis that has been carried out located on Jalan Jenderal Ahmad Yani, Palembang, the road capacity (C) is 2,924 PCU/hour and the free flow speed (VB) value is 49.59 Km/hour, while the road traffic performance and level of service on the Jalan Simpang 4 Jakabaring-Jalan Jenderal Ahmad Yani section is 0.81 and is classified as category D (Flow is close to stable, speed can still be controlled, traffic volume is approaching capacity), while from the direction of Jalan Jenderal Ahmad Yani -Intersection 4 Jakabaring obtained a service level of 0.94 and was classified as category E (Unstable flow and sometimes stopping, traffic volume approaching capacity, low speed and changing).

Abstract

This research focuses on the development of polymer mortar using epoxy as a binder, fly ash as an additive, and nanosilica as nano-filler. The study investigates the effect of nanosilica variations on the mechanical properties of polymer mortar, specifically density and compressive strength. The research used nanosilica content variations of 0%, 1%, 2%, 3%, 4%, and 5% of the mold volume. Material composition consists of 45% sand, 17.5% epoxy, 17.5% hardener, 20% fly ash, and varying nanosilica percentages. Test results show that increasing nanosilica content decreases the density of polymer mortar from approximately 1880 kg/m³ (0% nanosilica) to 1730 kg/m³ (5% nanosilica). Meanwhile, compressive strength increases up to 2% nanosilica content with an optimum value of 60.31 MPa (an 87.3% increase compared to mortar without nanosilica), then decreases with further addition of nanosilica. The findings suggest that 2% nanosilica represents the optimum content for enhancing the mechanical performance of epoxy-based polymer mortar.

Abstract

Traffic conflicts frequently occur at intersections. Unsignalized intersections are more prone to traffic conflicts than signalized intersections. Intersection performance is a key factor in determining the most appropriate measures to optimize intersection functionality. One unsignalized intersection in Palembang that frequently experiences traffic congestion is the section of Dr. M. Isa Street and Letda Abdul Rozak Street. This study aims to analyze intersection performance using the 2023 PKJI and VISSIM software to help simulate the most effective traffic engineering measures to reduce congestion. Analysis of data using the 2023 PKJI method yielded a queue probability of 39.36% –77.84%, a degree of saturation of 0.99, and an intersection delay of 18.58 seconds per vehicle. Based on the intersection performance analysis, a poor service level was identified. A highly effective traffic engineering alternative to address the poor intersection performance involves implementing a right-turn ban for vehicles on Dr. M. Isa Road (Toward Veteran) and Letda Abdul Rozak Road. The intersection performance analysis yielded a queue probability of 11.36%–25.40%, a degree of saturation of 0.51, and an intersection delay of 10.09 seconds/vehicle. The VISSIM simulation yielded a queue length of 0 meters and a maximum vehicle delay of 11.14 seconds/vehicle. With the implementation of the traffic engineering alternative prohibiting right turns, the intersection experienced an improvement in service level due to a reduction in queue length and vehicle delay.

Abstract

Keselamatan lalu lintas pada tahap konstruksi jalan tol merupakan isu penting karena adanya peningkatan risiko kecelakaan akibat perubahan geometri jalan, mobilisasi kendaraan proyek, serta pengaturan lalu lintas sementara yang mengganggu arus normal. Penelitian ini dilakukan pada proyek jalan tol Bayung Lencir–Tempino (Seksi 1 dan 2), dengan fokus pada titik pertemuan antara akses proyek dan jalan eksisting, khususnya di tikungan Harmoko. Metode penelitian menggabungkan analisis frekuensi kecelakaan, tingkat keparahan (severity), pemetaan spasial hotspot, serta pendekatan work zone untuk mengidentifikasi daerah rawan kecelakaan. Data teknis rencana jalan (RTA), karakteristik lalu lintas, dan variabel akses proyek dianalisis untuk memprediksi risiko. Model regresi Poisson dan Negative Binomial digunakan untuk memodelkan data kecelakaan berbentuk count data, dengan NB lebih unggul dalam menangani overdispersion. Hasil penelitian menunjukkan bahwa risiko kecelakaan meningkat pada zona dengan perubahan akses tidak terkontrol, mobilisasi alat berat, serta transisi geometri jalan. Mitigasi yang diusulkan meliputi penempatan rambu lalu lintas sesuai kondisi, penggunaan water barrier dan flag man, serta pengaturan kecepatan pada zona kritis. Evaluasi selama enam bulan menunjukkan hasil positif dengan tercapainya zero accident tanpa korban jiwa maupun luka. Penelitian ini menegaskan efektivitas metode work zone dalam mengidentifikasi risiko dan merancang mitigasi berbasis zona, sehingga dapat menjadi acuan dalam perencanaan keselamatan proyek jalan tol di Indonesia

Abstract

Urban flooding is a recurrent hydrometeorological disaster in Palembang, primarily caused by high-intensity rainfall, limited drainage capacity, and rapid urbanization. The spatio-temporal patterns identified in this study indicate a tendency for recurrent flood events to occur in the same locations, providing a basis for determining priority zones for urban flood vulnerability assessment and mitigation planning. This study analyzes 13 flood events recorded between 2024 and 2026 using data obtained from the Disaster Information System (SITABA) managed by the Ministry of Public Works of the Republic of Indonesia. The analyzed data include geographic coordinates, occurrence dates, flood causes, inundation depths, and impacts on infrastructure. Spatial analysis reveals that flood-prone areas are concentrated in the districts of Ilir Timur I, Ilir Timur II, Ilir Barat I, Seberang Ulu I, and Kemuning, which are characterized by extensive impervious surfaces and inadequate drainage systems. Temporal analysis indicates an increasing frequency of flood events, with inundation depths ranging from 10 to 80 cm. The primary causes of flooding were identified as high-intensity rainfall exceeding drainage system capacity, compounded by backwater effects from the Musi River. These findings provide important insights for urban flood mitigation planning, drainage system rehabilitation, and the development of more resilient urban water management strategies in Palembang City.
