Abstract

Suboptimal design and body shape in freight transport vehicles can lead to increased aerodynamic drag. To address this issue, the use of wind deflectors is proposed as a solution to reduce aerodynamic resistance in cargo vans. The methodology employed in this research involves Computational Fluid Dynamics (CFD) simulations using the Ansys Fluent R2 2023 software. CFD simulations were conducted on the design of a cargo box vehicle with variations in Wind Deflector Models 1, 2, and 3, employing identical boundary condition parameters. The results of the CFD simulation for Wind Deflector Model 3 exhibited the lowest drag force at 1.1531116 Newton and a drag coefficient of 0.37031338. In conclusion, a comprehensive analysis of the CFD simulation results provides valuable insights into the intricate aerodynamic implications of Wind Deflector variations on cargo vans. Therefore, it is concluded that Wind Deflector Model 3 emerges as the optimal choice, showcasing superior aerodynamic characteristics.

Abstract

The wheel rim serves as a component designed to provide stability and necessary support for vehicle tires. The phenomenon of resonance occurring when the external vibration frequency approaches the natural frequency of the structure has the potential to increase vibration amplitude, which can lead to wheel rim damage. This study aims to investigate the shape patterns and natural frequencies of 17-inch aluminum alloy wheel rims, as well as to analyze the maximum total deformation that occurs. The finite element method is employed to simulate the vibration characteristic of 17-inch aluminum alloy wheel rims under various natural frequencies. Modifications to the wheel rim design are made by altering the spoke angle in variations of 5°, 10°, and 15°. The vibration characteristic data of the wheel rim was obtained through simulation using ANSYS software. The research findings indicate that the natural frequencies range from approximately 364.7 Hz to 723.21 Hz. Furthermore, the maximum total deformation values range from approximately 9.7 mm to 22.5 mm.

Abstract

TThe manual measurement of materials using pneumatic systems for inspections remains prevalent, posing challenges in meeting the demands and speed of modern production processes. To address this, there is a critical need for an automated inspection tool capable of generating a significant number of inspection inputs. This research objectives to design and implement an automatic thickness inspection system, employing pneumatic technology and inductive proximity sensors. The study adopts an experimental research design, systematically progressing through literature review, algorithm design, PLC programming, and comprehensive testing. The pneumatic system, known for its high response speed and durability, is capable of accurately measuring material thickness and sorting items with precision. The integration of inductive proximity sensors enhances the system's efficiency in detecting both metallic and non-metallic objects. The research findings reveal a system effectiveness of 95.8% in the initial test and 91.7% in the subsequent test. Notably, deviations in the Ø12 sensor are identified in detecting NG minus material. Despite this, the system's overall effectiveness surpasses the 90% threshold, meeting stringent standard criteria. The study concludes with insights into the identified deviations and underscores the system's effectiveness in meeting high-standard criteria. Recommendations for improvement include modifications to the stopper or proximity sensor position, sensor recalibration, continuous monitoring, and material path separation

Abstract

This research aims to analyze the effect of oxygen pressure on the oxy-acetylene welding process concerning the mechanical properties of weld joints on 5052 aluminum plates. The variations of oxygen pressure used were 30 kg/cm², 40 kg/cm², and 50 kg/cm², with the acetylene pressure kept constant for each sample. Hardness testing was conducted to evaluate the hardness distribution in the base metal, Heat Affected Zone (HAZ), fusion line, and weld metal. The results indicate that oxygen pressure significantly affects the hardness values in the weld area. At an oxygen pressure of 30 kg/cm², the hardness reached 65.7 HV. Increasing the oxygen pressure to 40 kg/cm² resulted in the highest hardness value of 98.9 HV, indicating optimal conditions for forming a denser microstructure. However, at an oxygen pressure of 50 kg/cm², the hardness decreased back to 65.7 HV, suggesting that excessively high oxygen pressure can negatively impact the solidification process. From this study, it can be concluded that an oxygen pressure of 40 kg/cm² is the optimal parameter for achieving the highest hardness in the weld area. This research emphasizes the importance of controlling welding parameters to attain the desired mechanical properties in aluminum 5052 weld joints.

Abstract

Permasalahan limbah plastik rumah tangga terus meningkat seir-ing bertambahnya konsumsi masyarakat terhadap produk berba-han plastik. Di Perumahan Riverahills Zona 2 RT 005–007 Ke-lurahan Meruyung, limbah plastik masih didominasi oleh aktivi-tas pembuangan tanpa proses pemanfaatan yang optimal. Kondisi tersebut menunjukkan masih rendahnya pengetahuan dan ket-erampilan generasi muda dalam mengolah limbah menjadi produk yang bernilai guna. Pengabdian Kepada Masyarakat (PKM) ini bertujuan meningkatkan kesadaran lingkungan dan keterampilan anggota Karang Taruna melalui edukasi serta pelatihan pembuatan paving block berbahan limbah plastik. Metode yang digunakan meliputi observasi awal, penyuluhan mengenai konsep 3R (Reduce, Reuse, Recycle), demonstrasi proses pembuatan paving block, praktik langsung, diskusi inter-aktif, dan evaluasi menggunakan kuesioner. Hasil kegiatan menunjukkan sekitar 90% peserta mengalami peningkatan pema-haman mengenai pengelolaan limbah plastik dan mampu mengi-kuti tahapan pembuatan paving block sesuai prosedur. Selain itu, kegiatan berhasil meningkatkan kepedulian peserta terhadap lingkungan serta membuka peluang pengembangan usaha ber-basis ekonomi sirkular. Program ini membuktikan bahwa pelati-han berbasis praktik mampu meningkatkan kapasitas masyarakat dalam pengelolaan limbah sekaligus mendukung upaya pelestari-an lingkungan.
