Abstract

Bumpers are critical structures in passenger vehicles, designed to absorb low-speed impact energy. This study examines the effect of profile combinations (C-Hat and Double-Hat Section) and materials (Steel Bare/E.G.-H.F.80Y 100T, CFRP T700S, Aluminium 2024-T86) on MPV bumper reinforcement beam performance under UN ECE R.42 standards. Finite Element Method (FEM) simulations using ANSYS Explicit Dynamic with longitudinal impact tests (4 km/h) and side tests (2.5 km/h) were conducted to evaluate deformation, stress, and energy absorption. Results revealed that C-Hat Section with Aluminium 2024-T86 delivered optimal performance: von Mises stress 194.40 MPa, deformation 1.2057 mm, and energy absorption 160.31 J at 4 mm thickness. The Weighted Sum Model (WSM) analysis confirmed this combination as the best choice (score 1.773). The proposed design meets safety criteria while maintaining weight efficiency for MPV applications.

Abstract

Peningkatan volume lalu lintas pada ruas Jalan Raya Serpong, Kota Tangerang Selatan, tidak diimbangi dengan pengelolaan fasilitas putar balik (U-Turn) yang optimal, sehingga menyebabkan penurunan kinerja jalan dan efisiensi lalu lintas. Penelitian ini bertujuan untuk menganalisis pengaruh fasilitas U-Turn terhadap kinerja lalu lintas serta menentukan alternatif penanganan yang paling efektif. Metode yang digunakan adalah pendekatan kuantitatif deskriptif dengan analisis kinerja jalan mengacu pada Pedoman Kapasitas Jalan Indonesia (PKJI 2023) dan evaluasi U-Turn menggunakan teori antrean Jay dan Barry. Selain itu, dilakukan simulasi mikroskopik menggunakan perangkat lunak PTV Vissim untuk memodelkan kondisi eksisting dan menguji skenario perbaikan. Data primer diperoleh melalui survei lapangan yang mencakup volume lalu lintas, kecepatan kendaraan, waktu tempuh, panjang antrean, serta karakteristik geometrik jalan. Hasil penelitian menunjukkan derajat kejenuhan sebesar 0,52 dengan tingkat pelayanan (Level of Service/LOS) kategori E, yang mencerminkan kondisi lalu lintas tidak stabil dengan kecepatan rendah dan kepadatan tinggi. Panjang antrean maksimum mencapai 174 meter, dengan rasio tingkat pelayanan lebih dari 1 pada beberapa titik U-Turn, yang mengindikasikan kondisi jenuh dan gangguan lalu lintas yang signifikan. Hasil simulasi menunjukkan bahwa kombinasi pelebaran jalan, penutupan salah satu U-Turn, serta redesain fasilitas memberikan hasil paling optimal, dengan penurunan waktu tempuh sebesar 13,44% dan peningkatan kecepatan hingga 15,51%. Dengan demikian, keberadaan dan desain fasilitas U-Turn berpengaruh signifikan terhadap kinerja lalu lintas. Direkomendasikan penerapan rekayasa lalu lintas terpadu sesuai pedoman teknis guna meningkatkan efisiensi, mengurangi kemacetan, dan meningkatkan keselamatan pengguna jalan.

Abstract

Rear-end collisions between passenger vehicles and heavy trucks frequently result in high fatality rates due to underride events, in which the smaller vehicle slides beneath the truck. This underscores the need for improved passive safety systems, particularly the Rear Underrun Protection Device (RUPD), which serves to absorb impact energy. However, many existing RUPD designs only meet minimum regulatory requirements without optimizing energy absorption performance. This study aims to analyze and compare the influence of varying material types and structural configurations of the energy absorption box on the RUPD’s energy absorption capability. The evaluation focuses on deformation, stress distribution, and absorbed energy under impact loading conditions. The methodology involves three-dimensional modeling using SolidWorks and finite element method (FEM) simulations in Ansys. Materials including ASTM A36 steel, AISI 1020 steel, and Aluminum 2024 are combined with honeycomb structural variations. Simulations are conducted in accordance with UN ECE R.58 standards. Furthermore, the Simple Additive Weighting (SAW) method is applied to determine the optimal design. The results indicate that both material selection and structural configuration significantly affect energy absorption performance, with the honeycomb structure using filler with Aluminum 2024 demonstrating superior capability. This study contributes to the development of more effective RUPD designs aimed at enhancing road safety.

Abstract

Occupational Safety and Health (OHS) is a crucial aspect in fuel distribution operations, especially for Tanker Crews (AMT) as the frontline. This study aims to analyze the level of AMT awareness of OHS, identify inhibiting factors, and develop and measure the effectiveness of e-booklet media as a means of increasing OHS awareness in the Pertamina Fuel Terminal Boyolali environment. The research method used is mixed methods, with a quantitative approach through pre-test and post-test and a qualitative approach through interviews and observations. The research sample of 79 AMT was selected using a purposive sampling technique. The results showed that the level of AMT OHS awareness increased significantly after the e-booklet was provided. Internal factors such as knowledge and attitudes, as well as external factors such as supervision and the work environment, also influenced the level of awareness. The e-booklet media proved effective as a practical, interactive, and easily accessible educational medium, thus recommended as a means of continuous OHS training. This research contributes to the development of digital media-based occupational safety strategies in the hazardous materials transportation sector.

Abstract

The Purbalingga–Pemalang road has become a site of frequent traffic accidents due to its steep slopes, sharp curves, and lack of adequate road safety infrastructure. This study aims to assess the level of traffic accident risk using the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method, with the goal of identifying high-risk segments and dominant contributing factors. Primary data were collected through field inspections and hazard identification surveys, while secondary data were obtained from police accident reports over the past three years. Analysis focused on road conditions, safety facilities, and environmental factors. Results indicate that Segment 4 is the most hazardous, accounting for nearly 47% of accidents involving minor injuries and one fatality. Key risk factors include damaged pavement, poor visibility due to overgrown vegetation, lack of guardrails, and malfunctioning traffic signals. The risk assessment classified several segments as having moderate to high risk levels. These findings underline the urgent need for road surface repairs, improved traffic signage, vegetation management to enhance visibility, and stricter law enforcement. The study highlights the importance of integrating hazard-based risk assessment methods in transport planning and infrastructure maintenance. By addressing these critical issues, it is expected that traffic accidents on this road can be significantly reduced, thus improving overall road safety for all users.

Abstract

As a mass transportation system infrastructure, level crossings impact road users, including skidding, roaddamage, and accidents. Based on data from KAI DAOP 4 Semarang, there were 12 accidents at level crossingsin 2023, while in 2024, the number increased to 26, indicating a rise in accident rates. One accident that wentviral on social media occurred in Semarang in 2023, involving a low-bed trailer that got stuck at a levelcrossing. The objective of this study is to analyze and evaluate level crossings, assess their compliance withregulations, and provide recommendations for improvements. This research employs the triangulation method,utilizing data obtained from geometric surveys and an inventory of crossing equipment. The study focuses onlevel-crossing locations JPL 6 Madukoro and JPL 5 Kaligawe in Semarang City. The findings indicate that theexisting conditions do not fully comply with regulatory requirements in terms of facilities and geometricspecifications. Specifically, the Madukoro crossing is constructed at a higher elevation than the surroundingtopography, creating a hump with a height of 86 cm above the road surface and a grade of 12.8%. Thiscondition increases the risk of long vehicles, such as low-bed trailers, getting stuck, potentially leading tosevere accidents. Therefore, it is recommended that regulations concerning level crossings be reviewed andrevised.
