Abstract

The rapid growth of motorized vehicles in Palembang City has significantly impacted traffic congestion, particularly at the U-Turn facility in front of Dr. Mohammad Hoesin General Hospital (RSMH) on Jendral Sudirman Street. This study aims to analyze the performance of the U-Turn at this location through field surveys and secondary data analysis. Primary data include traffic volume, vehicle speed, queue length, and side friction, while secondary data were obtained from relevant institutions. The analysis results show that the degree of saturation (DS) reached 1.32 for the RSMH direction and 1.27 for the LIA direction, both exceeding the PKJI 2023 recommended limit (DS ≤ 1.0). The level of service (LOS) was classified as F, with the lowest average speed of12.11 km/h and a queue length of up to 78 meters during the Monday morning peak hour. The main factors contributing to the performance decline include high vehicle volumes, side friction from illegal parking and drop-off activities, and limited median width. These findings highlight the need for traffic management interventions such as controlling side friction, widening the median, or implementing signalized U-Turns to improve traffic flow efficiency.Keywords: traffic performance, U-Turn, degree of saturation, queue length, level of service

Abstract

This study aims to analyze the effect of using coconut fiber ash as a filler on the stability and density of AC-WC type asphalt mixtures using SIR 20 rubber asphalt. The abundant and underutilized coconut fiber waste encourages this research as an innovation for alternative filler materials in road pavement mixtures. The method used is a laboratory experiment with variations in coconut fiber ash content of 0%, 4%, 6%, 8%, and 10% of the total filler. Each variation was tested using the Marshall method to assess stability, flow, VIM, VMA, VFA, and Marshall Quotient (MQ). The results show that the addition of coconut fiber ash influences the improvement of the mixture's stability and density. The optimum variation was obtained at a certain filler content that provided the best balance between high stability, appropriate flow, and VIM and VFA values within the Bina Marga specifications. Therefore, coconut fiber ash has the potential to be used as an environmentally friendly and economical alternative filler in road pavement construction. Keywords: Coconut fiber ash, AC-WC, filler, stability, density, Marshall.

Abstract

The increasing population and vehicle ownership in Palembang City, particularly in the Government Office area along Jalan Merdeka, have caused significant parking shortages. This situation forces many vehicles, both from employees and visitors, to use on-street parking, which disrupts traffic flow. This study aims to analyze parking characteristics, including volume, accumulation, duration, turnover rate, parking index, current parking demand, and projections for the next five years, as well as to identify effective parking arrangement alternatives. The research method involved a five-day field survey on weekdays at three main locations, measuring existing parking capacity, recording vehicle entries and exits, and analyzing parking characteristics based on the Technical Guidelines for Parking Facility Management (Directorate General of Land Transportation, 1996). The results indicate that the existing parking capacity does not meet the standard Space Unit for Parking (SRP), with an average parking index exceeding 100% for both two-wheeled and four-wheeled vehicles. This condition highlights the urgent need for additional or optimized parking spaces. Recommended solutions include developing centralized parking facilities, implementing multi-story or mechanical parking systems, and applying scheduled parking management to improve efficiency and reduce congestion. Keywords : Parking, Capacity, Parking Index, On-Street Parking
