Development of a Web-Based Application “Sistem Evaluasi Kinerja Ruas Jalan Perkotaan (Si-EJA)”
Section: Articles Keywords: road performance, traffic congestion, PKJI, web-based application, HTML, PHP, urban transportation, traffic evaluation, road information system The rapid growth of vehicle numbers, unmatched by the expansion of road infrastructure capacity, has become a major cause of traffic congestion in urban areas. This condition not only disrupts mobility but also leads to energy waste, economic losses, and reduced transportation system efficiency. Evaluating road segment performance is a strategic step to assess the level of service and to formulate appropriate traffic management policies. However, conventional evaluation methods—relying on manual surveys and complex calculations—are often inefficient and prone to error. This study proposes the design of a web-based application for calculating urban road performance using PHP and HTML, which automates calculations based on PKJI standards. The application enables users to input traffic data and instantly obtain performance analysis results in real time, making it a reliable decision support tool. The implementation of web technology also promotes data transparency, processing efficiency, and cross-device accessibility, positioning it as an adaptive solution to modern urban transportation challenges.

Analysis of Fluctuations in Consumption and Power Input of Transjakarta Electric Bus Battery Flow
Section: Articles Keywords: electric bus , State of Charge , Transjakarta , battery charging , energy efficiency The increasing use of electric vehicles as a sustainable transportation solution also encourages their integration into public transportation systems, such as those implemented by PT Transportasi Jakarta. One important aspect of electric bus operations is the efficiency of power consumption and the effectiveness of battery charging. This study aims to analyze the percentage decline in State of Charge (SoC), energy efficiency (kWh/km), and battery charging characteristics of the Zhongtong Medium Low Entry electric bus operating on Transjakarta routes under two operational conditions: without passengers and with passengers. The method used involved direct observation and field data recording over four testing periods, covering energy consumption, distance traveled, and charging capacity, with tests conducted under both operational conditions. The results show that the presence of passengers causes an average SoC decrease of 17% compared to the condition without passengers, and an increase in energy consumption of 43%, from 0.27 kWh/km to 0.70 kWh/km. The incoming electrical power during charging exhibited greater variation under the passenger-loaded condition; however, the average difference was only about 2%, indicating a relatively small impact on the battery charging process. These findings confirm that the additional passenger load significantly affects energy consumption efficiency and SoC levels of electric vehicles but has minimal influence on charging power. This study provides important contributions to energy management and the development of battery charging infrastructure for electric buses to support more efficient and sustainable operations.

Measurement of Situation Awarness Level in Public Transportation Drivers with QUASA Method
Section: Articles Keywords: situational awareness, driver alertness, QUASA, transportation safety, public transportation Situational awareness of public transport drivers has an important role in transportation safety. Measurement of the level of alertness of Perum DAMRI drivers is proposed using the QUASA (Quantitative Analysis of Situational Awareness) method. The method used was descriptive quantitative and qualitative with a sample of 86 respondents from a total population of 627 drivers. Data were collected through documentation (accident data and driver data), and questionnaires (driver alertness test data), analyzed using awareness calibration, Signal Detection Theory (SDT), and sensitivity and bias calculations. The results showed that the driver's actual accuracy value was 61.9%, lower than the perceived accuracy which reached 82.1%. The driver's alertness level only reached 65.4%, which is still below the safe limit. Sensitivity analysis shows that drivers are able to distinguish between signals and noise, but with a level of accuracy that still needs to be improved. The bias calculation results show that drivers tend to have difficulties in dealing with ambiguous stimuli. Emphasizing the importance of increasing driver vigilance through training, stricter.

The Analysis and Recommendations for High-Risk Accident Areas on the Gempol-Pasuruan Toll Road
Section: Articles Keywords: accident-prone areas, toll road, road safety Gempol Pasuruan Toll Road is a series of Trans Java toll roads. The large number of vehicles crossing this toll road is accompanied by an increase in the number of accidents that occur. Based on data for 2021-2023, a total of 28 accidents occurred with details of minor injuries 15 people, serious injuries 30 people, and deaths 16 people. Analysis of accident-prone areas is carried out to find out and identify safety problems that exist on toll road sections. This is done using the Equivalent Accident Number (EAN) method and using the Upper Control Limit (BKA) and Upper Control Limit (UCL) values. From the results of the analysis carried out, KM 786+600 is an accident-prone area on the Gempol Pasuruan Toll Road. The installation of strobe lights, rumble strips, and installation of traffic signs and Variable Massage Signs (VMS) are expected to reduce the number of accidents that occur on the Gempol-Pasuruan Toll Road, especially at accident-prone areas, namely KM 786+600.

Analysis Of The Risk Of Traffic Accidents For Electric Bike Users
Section: Articles Keywords: Electric Bicycle, Traffic Accident, Risk, Safety Electric bicycles are becoming an increasingly popular mode of transportation due to their practicality and environmental friendliness. The increasing use of electric bicycles is accompanied by the risk of traffic accidents that cannot be ignored. Analysis of factors that influence accidents and evaluating the level of risk for electric bicycle users is the main objective. Descriptive analysis method with a qualitative approach is used based on accident data involving electric bicycles. The factors analyzed include road conditions, driver behavior, and awareness of traffic safety. Road conditions with uneven surfaces (63%) and lack of lighting (60%) are possible risks of accidents due to poor road infrastructure. The behavior of not wearing a helmet (65%) and not obeying traffic rules (58%) are major risks of accidents. The main causes of accidents are driver error (50%), road conditions (30%), and vehicle technicalities (25%). Awareness of the importance of using personal protective equipment such as helmets by drivers is still relatively low. The risk of accidents can be minimized by increasing awareness of driving safety, tightening the use of electric bicycles, improving road infrastructure, and encouraging users to maintain their vehicles regularly. Infrastructure improvements and safety campaigns are needed to reduce the risk of accidents involving electric bicycles in the future.

Analysis of Service and Satisfaction of Special Bicycle Lanes on Urban Roads
Section: Articles Keywords: BLOS, Infrastructure, IPA, Cyclist Comfort, Bicycle Lanes Bicycle lanes in Yogyakarta City have problems including uneven road surfaces, non-standard lane widths, and faded road markings. Minimal traffic signs and the placement of electric poles in bicycle lanes increase the potential for disruption to cyclists' comfort and safety. Analysis of service and satisfaction of bicycle lanes on urban roads on Jalan Patehan Lor and Jalan Nagan Kulon in Yogyakarta City is proposed using the Bicycle Level of Service (BLOS) and Importance Performance Analysis (IPA) methods. The service analysis on both roads obtained a BLOS E value, which means that the lanes do not meet the comfort standards for basic experienced cyclists. The satisfaction analysis found that lane width and road surface conditions are among the top priorities for improvement. The improvement strategies that need to be carried out are that the width of the lane and uneven road surface need to be repaired immediately, including widening the bicycle lane, repairing the road surface, painting the markings, and adding bicycle lane signs, speed limits, and cyclist priority signs.
