Abstract

Bushing arms are critical automotive components that function as vibration dampers and load absorbers. The problem is that the bushing arm often fails due to several factors, including the use of inappropriate materials, poor road quality, lack of routine maintenance, and external factors such as extreme temperatures, exposure to corrosion, and excessive pressure. This study aims to optimize bushing arm design and material selection to improve durability and vibration-damping performance under acidic exposure conditions. Two rubber materials, Natural Rubber (NR) and Ethylene-Propylene Diene Monomer (EPDM), were evaluated for MPV-type vehicle bushing arms. Three design variations were developed and analyzed using hyperelastic Finite Element Analysis (FEA) to assess stress distribution, strain, deformation, and safety factor. The rubber specimens were fabricated by hot pressing at 180°C and 7 MPa, followed by immersion in 15% phosphoric acid at 65°C to evaluate chemical degradation. Mechanical characterization included tensile testing (ASTM D412), Shore hardness testing, and microstructural observation. The results showed that acid immersion reduced tensile strength by 20.44% for NR and 23.80% for EPDM, while elongation decreased by 38.3% and 17.43%, respectively. Hardness decreased by 19.2% for NR and 4.81% for EPDM. FEA results indicated that design C achieved the lowest deformation, reducing it by 51%, while design B reduced shear stress and von Mises stress by up to 70%. Based on the combined mechanical and simulation results, design B with NR material was selected as the preferred configuration.

Abstract

Research related to rubber seed conversion to oil and activated carbon as filter media requires further exploration. Therefore, the main objective of this study to investigate the rubber seed oil as alternative energy and rubber seed Shell Activated Carbon (RSSAC). Thermo-chemical method conducted with separation process between the kernel and the shell. The process used temperatures of 550 and 600°C. Biodiesel was produced by a blending process using a frequency of 20kHz, temperature of 60oC and 2h holding time. In addition, the side product was converted into activated carbon through carbonization and activation using KOH. Air filter fabricated using three layers, where the top and bottom layers being non-woven and RSSAC in the middle. It compacted using hot-press method at temperature of 150°C for 60 s to produce an air filter media thickness of 3–5mm. The results show that there are several high compound concentrations i.e. CH4, aldehydes, and ketonestone. Several gases evolve, such as CO2, CO, CH4, H2O, ketone aldehyde, and HC. Microstructure analysis using Scanning Electron Microscope (SEM) of RSSAC shows that element C significantly increase up to 80%, while O, K, and Ca decreased up to 72%, 66% and 90%, respectively. RSSAC has a large surface area of 175.95m2/g, and it will have high effectiveness in improving indoor air quality (IAQ). This is indicated by the result of IAQ analysis where the humidity, temperature, CO, CO2, TVOC, and PM10 were lower than the acceptable limit of 70%, 27oC, 1000ppm, 10ppm, 3 ppm, and 0.15 mg/m3, respectively.

Abstract

Congestion at toll roads has become a pervasive issue in contemporary times, predominantly manifesting at toll booths during the payment process. A noteworthy contributor to this congestion has been identified as the sluggish operational speed of boom gates. In response to this challenge, a modification strategy was implemented to enhance the operational efficiency of existing boom gates. The primary modification involved substituting the conventional electric motor with a more advanced Brushless DC (BLDC) motor boasting a power rating of 660 watts. Additionally, an innovative augmentation integrated a motorcycle disk brake system into the boom gate mechanism. Replacing the original electric motor's internal brake system with the disk brake system aimed to optimize the overall performance of the boom gate. The integration of the motorcycle disk brake system was further complemented by incorporating the push braking system (knoken braking system), serving as the actuator instead of the traditional motorcycle lever handle. This strategic substitution was instrumental in activating the disk brake function at the boom gate. During peak rush hours, the modified boom gate underwent rigorous testing at both the Ciawi and Kelapa Gading toll gates. Results from the trial activities unveiled a remarkable improvement in the boom gate's operational speed. Specifically, the opening speed demonstrated an impressive surge of 51 percent, catapulting from 548 ms to 265 ms. Similarly, the closing speed exhibited a commendable enhancement of 44 percent, elevating from 602 ms to 332 ms. Furthermore, the boom gate cycle per hour experienced a notable escalation, increasing by 25 percent from 356 to 449 cars per hour. These findings underscore the efficacy of the implemented modifications in ameliorating congestion issues at toll booths.

Abstract

Electro-deposition process to develop surface layer on the substrate material in Catalytic converter (CATCO) become interesting area due to that process was purposed to improve the physical properties of substrate material. Currently, precious metals such as Platinum (Pt), Palladium (Pd), and Rodium (Rd) were used due to excellent oxidation resistant but it limited and easily oxidized. Therefore, Nickel Oxide (NiO) catalyst used as electro-deposition material. NiO electro-deposition technique that called by EL was conducted by using NiO as cathode and FeCrAl as substrate and -Al2O3 as washcoat material. This technique was performed by  variation times of 15, 30, 45, 60 and 75 minutes, current density of 8 A/dm2. The results shows that Coating layer of NiO and  -Al2O3 has been developed on surface of FeCrAl substrate. The coating layer was increase the surface roughness which showed by surface morphology data that coated FeCrAl substrate has uneven surface and some particles has been embedded on that surface. The composition of raw material was consists of Fe for 74.13wt%,  Cr of 20.25 wt% and Al of 5.62 wt%.

Abstract

Abstract: The braking system is a critical component in vehicles, ensuring effective and safe deceleration. Disc brakes, commonly used in automotive applications, generate significant heat during operation, which if not managed properly, can lead to serious problems such as brake fading and component failure. This study reviews various methodologies and findings from previous research on thermal management in disc brakes using Finite Element Analysis (FEA) and other experimental methods. Key findings include the effectiveness of improved ventilation designs, the impact of cooling fins, and the role of composite materials in enhancing heat dissipation. The study also examines the influence of geometric design variations and operating conditions on thermal performance. The results highlight that advanced materials like ceramics, cross-ventilated rotors, and active cooling fins significantly improve thermal efficiency and reduce overheating risks. Furthermore, mathematical modeling techniques such as Response Surface Methodology (RSM) and Distance Weighted Least Squares (DWLS) fitting models provide valuable insights for optimizing disc brake systems. The review underscores the importance of comprehensive thermal management strategies to ensure the safety and reliability of braking systems under various operational conditions. Future research should focus on addressing the limitations of current FEA models and developing more efficient materials and rotor designs.   Keywords: Braking System, Thermal Management, Finite Element Analysis

Abstract

ABSTRAK Kecelakaan lalu lintas di Indonesia masih didominasi oleh faktor kesalahan manusia (human error), yang berkontribusi pada lebih dari 70% dari total kejadian kecelakaan. Pasal 90 Undang-Undang Nomor 22 Tahun 2009 tentang Lalu Lintas dan Angkutan Jalan (UU LLAJ), yang dijabarkan lebih lanjut melalui Peraturan Pemerintah Nomor 27, 28, dan 29 Tahun 2015, mewajibkan pemasangan perangkat pembatas kecepatan dan sistem monitoring kelelahan pengemudi pada kendaraan angkutan penumpang dan barang. Namun, implementasi teknologi monitoring yang efektif dan terjangkau di lapangan masih terbatas. Program pengabdian kepada masyarakat (PkM) ini bertujuan mengimplementasikan dan menguji coba purwarupa SLIFA Connect — sistem pemantau perilaku pengemudi berbasis kecerdasan buatan (AI) dan Internet of Things (IoT) dengan deteksi multivariabel (indikasi mengantuk, penggunaan handphone, merokok, dan rem mendadak) — pada armada transportasi mitra industri. Kegiatan dilaksanakan melalui fabrikasi 20 unit purwarupa, uji laboratorium (Electromagnetic Compatibility/EMC dan Power Quality Monitoring/PQM), serta uji lapangan pada 10 unit armada truk dan bus milik PT Anugerah Sarana Dinamika (ASD), hasil kolaborasi dengan Universitas Mercu Buana. Hasil menunjukkan seluruh purwarupa lolos uji emisi elektromagnetik dan mampu mendeteksi serta mengirimkan notifikasi pelanggaran (event) secara real-time ke server slifa.io, meliputi penggunaan ponsel, indikasi mengantuk melalui analisis frekuensi menguap, aktivitas merokok, dan pengereman mendadak. Implementasi SLIFA Connect terbukti memberikan solusi monitoring yang objektif, real-time, dan terdokumentasi bagi manajemen armada mitra, sehingga diharapkan dapat mendukung penurunan risiko kecelakaan sekaligus kepatuhan terhadap regulasi keselamatan transportasi jalan. Kata Kunci: Sistem Monitoring Pengemudi, Kecerdasan Buatan, Internet of Things, Keselamatan Transportasi, Pengabdian Masyarakat.  ABSTRACT Traffic accidents in Indonesia are still dominated by human error factors, which contribute to more than 70% of total accidents. Article 90 of Traffic Law No. 22/2009, further elaborated through Government Regulations No. 27, 28, and 29 of 2015, mandates the installation of speed-limiting devices and driver fatigue monitoring systems on passenger and freight vehicles. However, effective and affordable field implementation of such technology remains limited. This community service program aims to implement and field-test the SLIFA Connect prototype — an AI- and Internet of Things (IoT)-based driver behavior monitoring system with multivariable detection (drowsiness, mobile phone use, smoking, and sudden braking) — on the fleet of an industry partner. Activities were conducted through the fabrication of 20 prototype units, laboratory testing (Electromagnetic Compatibility/EMC and Power Quality Monitoring/PQM), and field trials on 10 truck and bus units belonging to PT Anugerah Sarana Dinamika (ASD), in collaboration with Universitas Mercu Buana. Results show that all prototypes passed electromagnetic emission testing and successfully detected and transmitted real-time violation notifications to the slifa.io server, including mobile phone use, drowsiness indication through yawning frequency analysis, smoking activity, and sudden braking. The SLIFA Connect implementation provides an objective, real-time, and well-documented monitoring solution for partner fleet management, supporting both accident-risk reduction and compliance with road transport safety regulations. Keywords: Driver Monitoring System, Artificial Intelligence, Internet of Things, Transportation Safety, Community Service.
