Abstract

The choice of transportation mode is a crucial aspect of student mobility, especially in higher education environments with high levels of activity. Students tend to select transportation modes based on cost, travel time, convenience, accessibility, and safety. However, the high use of private vehicles among students has led to increased traffic congestion and road accidents, as seen in Bengkulu City. On the other hand, the suboptimal quality of public transportation services has contributed to the low interest of students in using public transport. This study aims to analyze the factors influencing the transportation mode choice of Universitas Bengkulu students and to evaluate the effectiveness of public transportation services. The method used is binary logistic regression analysis combined with stated preference to understand mode preferences based on cost and travel time comparisons. The resulting mode choice model indicates that students prefer private vehicles unless public transportation offers more competitive costs and travel times. The study results reveal that travel cost and time are the most influential factors in mode selection. If public transportation becomes more affordable or offers shorter travel times, students are more likely to switch to it. The study concludes that improving the quality of public transportation services, particularly in terms of cost efficiency and punctuality, can increase student interest in using public transport, thereby supporting a more sustainable transportation system.

Abstract

Aircraft Classification Rating-Pavement Classification Rating (ACR-PCR) is a system to determine the PCR value of runway pavement strength and recommended for runway maintenance issued by International Civil Aviation Organization (ICAO) based on ICAO Advisory Circular (AC) 150/5335-5D of 2022, as a replacement for the Aircraft Classification Number - Pavement Classification Number (ACN-PCN) system that has been used since 1980. The implementation of the ACR-PCR Method is determining the strength value of runway pavement can be used as a reference in holding the load of aircraft that have a lower or the same ACR value. The ACR-PCR system was published in order to plan a more rational pavement structure strength by analyzing the response of the pavement structure to the weight of aircraft movement on the runway. The calculation was carried out using the modulus of elasticity of each layer on the runway pavement structure with a more specific type of material. Sultan Mahmud Badaruddin (SMB) II Airport is one of the airports in Indonesia that is currently in the process of transitioning using the ACN-PCN system to ACR-PCR system for runway strength reporting. Base on data of aircraft movement at SMB II airport management in 2024 and calculated by using FAARFIELD 2.1 software, PCR value for the critical runway strength of SMB II Airport was 890 F/C/X/T with a critical aircraft is Boeing B747-400.
