Abstract

Efficient and reliable public transportation systems, particularly bus services, played a crucial role in regional mobility and economic development. However, maintenance challenges impacted service quality, as seen in PT. SPS – Solo’s Scania fleet. Traditional reactive maintenance methods proved insufficient, leading to increased operational costs and unexpected failures. This study applied Reliability-Centered Maintenance (RCM) to optimize maintenance policies, identifying critical components and establishing effective strategies. Failure Mode and Effect Analysis (FMEA) revealed the brake chamber as the most critical component, followed by the stabilizer and tie rod/slack adjuster. Maintenance interval analysis recommended Time-Directed (TD) intervals from 26,090 km to 35,084 km and Condition-Directed (CD) intervals from 25,900 km to 70,168 km, based on component degradation patterns. Cost analysis highlighted air bellows as the highest-cost component (Rp. 2,350,000), while brake chambers had the lowest cost (Rp. 150,000). The study demonstrated that RCM improved fleet reliability and reduced maintenance costs. Implementing structured maintenance schedules, training programs, and condition monitoring systems was recommended. These findings provided a foundation for enhancing longdistance bus operations and could be adapted for other transportation sectors to achieve cost-efficient and reliable fleet management.

Abstract

The condensation process of smoke in charcoal-burning systems generates high temperatures that pose a critical thermal risk to PVC piping, which has a melting point of 85 °C. This study presents the design and implementation of a distributed temperature sensing system using dual-channel Type-K thermocouples controlled by an Arduino Uno microcontroller. The system is equipped with fault-tolerant logging and real-time monitoring features, utilizing the MAX6675 thermocouple amplifier module for digital signal acquisition. Two sensors are strategically placed along the smoke conduit to capture temperature differentials between primary and secondary zones. Experimental testing was conducted over six consecutive days with data acquisition sessions at noon and midnight. The highest recorded temperature from the primary sensor reached 83.75 °C, while the secondary sensor recorded significantly lower values, indicating a thermal gradient of 23.8 °C between inlet and outlet. Comparative calibration using an umbrella-type analog thermometer revealed a minimal deviation of 0.41 °C, confirming the system’s accuracy. Two sets of error profiling showed variations in measurement consistency, with average error rates of 13.79% and 5.93% across a 30 °C–80 °C reference range. Voltage stability was maintained throughout all test scenarios, with a constant 5 V input and 4.4 V output. The system successfully demonstrated its ability to perform dual-point thermal detection with resilient performance under fluctuating combustion conditions. This sensor-integrated platform is well-suited for thermal protection and early intervention in biomass-based liquid smoke condensation systems, particularly in small-scale applications using low-melting-point materials such as PVC.

Abstract

Brake fade due to excessive heat remains a leading cause of vehicular accidents, particularly among heavy-duty and public transportation vehicles. This issue is exacerbated by the limitations of conventional brake monitoring systems that lack real-time response capabilities. To address this challenge, this study develops a Smart Brake Thermal Management system based on Internet of Things (IoT) technology, designed to detect and deliver multi-modal alerts in response to potential brake overheating. The system integrates precision thermocouple sensors, an ESP32 microcontroller, an OLED display, and cloud-based notifications via Telegram. Using a Research and Development (R&D) methodology, the system was validated through six controlled road tests under standardized conditions. Results indicate high temperature measurement accuracy at 98.07% and 98.62% for dual sensor configurations, with system response times of less than two seconds. The warning mechanism effectively delivered synchronized notifications via visual indicators, audible alerts, and instant messaging. This system demonstrated a strong ability to identify the risk of brake fade before critical failure occurred, enhancing vehicular safety significantly. Its modular design and cost-effective implementation also make it suitable for large-scale retrofitting in existing vehicle fleets. The primary contributions of this research include the integration of multi-modal warning systems, real-time thermal monitoring through cloud connectivity, and a predictive approach to brake temperature management that improves proactive safety interventions.

Abstract

The increasing demand for reliable motorcycle braking systems requires accurate performance evaluation under controlled conditions, where a brake testing device plays an important role and its structural integrity becomes a key factor in ensuring safe and stable operation. The design and structural evaluation of a motorcycle disc brake testing device are conducted using the Finite Element Method (FEM), focusing on the main components including the frame, load actuator, and load holder under static loading conditions. The structure is constructed using ASTM A36 steel to provide adequate strength and stiffness, while mechanical components such as the electric motor, brake disc, and shaft are simplified as equivalent loads to reduce computational complexity without compromising realistic working conditions. The simulation results show that the maximum von Mises stresses on the frame, load actuator, and load holder are 42.92 MPa, 56.02 MPa, and 68.18 MPa, respectively, which are below the material yield strength of 250 MPa, with maximum displacements within acceptable limits and safety factors greater than 3, indicating that the structure is safe and reliable for operation.

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.
