Abstract

Pengabdian Kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan keamanan dan kenyamanan para pemudik yang mengalami kendala pada kendaraan nya yang melewati daerah sekitar palur, Kabupaten Karanganyar pada lebaran tahun 2023. Bengkel siaga merupakan tempat pengecekan kendaraan yang mengalami masalah di jalan dan membantu masyarakat agar sampai di daerah asal dengan selamat. Konsep bengkel siaga ini juga berdampak positif pada mahasiswa untuk meningkatkan kemampuan bersosialisasi dan mengaplikasikan ilmu yang di dapat di kelas dengan terjun langsung ke lapangan. Perawatan pada sepeda motor yang baik akan memastikan keamanan dan kenyamanan saat berkendara di jalan sehingga akan berkurangnya resiko insiden yang tidak diinginkan. Namun, di saat mendekati lebaran banyak bengkel yang tidak melayani selama hari libur lebaran. Penelitian ini dilaksanakan melalui serangkaian kegiatan sosialisasi yang melibatkan masyarakat Desa Ngringo dan petugas siaga lebaran tahun 2023 di Kabupaten Karanganyar. Kegiatan ini mencakup penyuluhan tentang adanya bengkel siaga lebaran dan tempat istirahat bagi pemudik. Hasil dari Pengabdian Kepada Masyarakat ini membuktikkan pemudik yang mengalami kendala merasa terbantu dengan adanya bengkel siaga. Selain itu, kegiatan ini juga memberikan manfaat ekonomi bagi bengkel lokal karena meningkatnya permintaan sparepart yang dibutuhkan pemudik bagi kendaraannya. Penelitian ini memberikan kontribusi positif terhadap keselamatan pemudik yang melintas di daearah palur pada mudik lebaran tahun 2023. Dengan peningkatan ini, diharapkan dapat mengurangi kecelakaan berkendara dan meningkatkan keselamatan berkendara di daerah tersebut. Selain itu, kegiatan bengkel siaga ini dapat menjadi contoh bagi daerah lain agar pemudik merasa aman bila melewati daerah tersebut.

Abstract

This study presents a static stress analysis on the side stand of a matic motorcycle using Steel Alloy material, applying the finite element method and SolidWorks software. Motorcycles are a popular means of transportation, especially in rural areas where users often modify the side stand to support additional loads. The side stand is a critical component that allows the motorcycle to remain stable when parked. However, this component frequently encounters damage due to loads exceeding its initial design capacity. This research aims to evaluate the structural strength and safety factor of the side stand under a 2240 N load. Simulation results indicate that the maximum stress experienced remains below the yield strength of the Steel Alloy used. The obtained safety factor supports the material's application in side stand structures, provided that load limits are observed. This study is expected to contribute to the development of more load-resistant side stand designs, especially for rural usage needs.

Abstract

The racing cast wheel made of aluminum 6061-T6 is a critical component in motor vehicles, particularly in supporting performance, safety, and aesthetics. This study aims to analyze the mechanical performance of the wheel through Finite Element Analysis (FEA) simulation. The FEA simulation was conducted using Ansys 18.1 software with a load of 1500 N, covering both static and dynamic loading conditions. The material tested is Aluminum Alloy 6061-T6, with material properties derived from tensile testing. The simulation results indicate that maximum stress occurs in critical areas, such as bolt holes and the intersection of spokes with the wheel rim, with a maximum stress value of 46.027 MPa. This stress level remains below the material's yield strength (276 MPa), demonstrating that the design is safe from plastic deformation. The total deformation observed is 0.053 mm, which is negligible and does not affect the wheel's functionality. A safety factor exceeding 2.5 confirms that the wheel can withstand more extreme loads. Based on these findings, design optimizations such as adding fillets and surface treatments are recommended to enhance the wheel's reliability. This research provides valuable insights for the development of stronger, lighter, and more durable wheels, particularly suited to the diverse road conditions found in Indonesia.

Abstract

Car wheels are critical components responsible for bearing vehicle loads and ensuring stability during driving. This study aims to analyze the strength of car wheels using the Finite Element Method (FEM) with Solidworks 2020 software. The analyzed parameters include von mises stress, equivalent strain, displacement, and safety factor. Simulation results show a maximum stress of 1.978 × 10⁵ N/m² and a maximum strain of 2.449 × 10⁻⁶, within the safe limits of aluminum alloy material. A maximum displacement of 5.687 × 10⁻⁴ mm indicates sufficient structural stiffness of the wheel. The minimum factor of safety, 1.087 × 10³, suggests a high tolerance against failure. This study confirms that the wheel design is safe, efficient, and meets safety standards. The finite element method effectively identifies critical areas and optimizes the design before production. Validation through physical testing is recommended to ensure alignment with real-world conditions.

Abstract

This study aims to analyse the effect of external loading on the distribution of plastic strain in API 5L X80 steel pipes using the Finite Element Method. External loading was modelled through an indentation process using a spherical indenter with diameter variations of 75 mm, 100 mm, and 125 mm, and indentation depths of 2 mm, 3 mm, and 4 mm. The simulation was conducted under zero internal pressure conditions to evaluate the plastic strain distribution formed after loading. The results show that increasing the indentation depth significantly increases the maximum plastic strain value and expands the deformation area on the pipe wall. Conversely, increasing the indenter diameter tends to reduce the maximum plastic strain value but broadens the affected area of strain distribution. The maximum strain concentration is located at the dent’s flank rather than the root, which is caused by the load distribution from the spherical indenter toward the transition area. These findings highlight the importance of dent geometry parameters in predicting the plastic strain response of pipes, providing valuable insights for assessing the structural integrity of pipelines in oil and gas industry applications

Abstract

Bottlenecks are a major cause of productivity decline in manufacturing systems. In the PDAM metal box industry at PT. MNO, the production process frequently encounters constraints that reduce output. This study employed discrete event simulation using ProModel software. The research stages included field observation, process time data collection, data distribution analysis with Stat::Fit, and model validation through Chi-Square and Mann-Whitney tests. The simulation revealed a significant bottleneck in the assembly workstation, with utilization reaching 93.64%, while production output was limited to 22 units during a 7-hour working shift. In contrast, the finishing station experienced idle time. An improvement scenario involving the addition of one workstation and one operator in the assembly and finishing processes is recommended to reduce production flow imbalances. This study confirms the effectiveness of discrete event simulation as an analytical tool for production system optimization and highlights opportunities for further development through digital twin integration and metaheuristic optimization

Abstract

This study aims to examine the relationship and comparison of motor performance based on different fuel injector angles in a fuel injection system, and to identify the optimal injector angle for improved engine performance. Fuel injection is a control technology that regulates the air–fuel mixture entering the combustion chamber with speed, precision, and proportional balance. An experimental method was employed using a 2020 motorcycle with a 108 cc engine. The tests conducted included torque, power, and exhaust emission measurements. Torque and power were measured using a dynamometer, while exhaust emissions were analyzed with a gas analyzer. The study compared injector mounting angles of 60°, 70°, and 80°. Results showed that torque increased significantly from low engine speeds (around 3000 rpm) and peaked between 3500–3750 rpm before gradually declining. Among the tested angles, the 80° injector position produced the highest torque across most speed ranges, reaching approximately 15 Nm at 3500 rpm. The 70° angle yielded moderate performance, while the 60° angle demonstrated the lowest torque, especially at medium to high speeds. Overall, the study found that increasing the injector angle enhances torque and power output, with average increases of 6.1% in power and 6.4% in torque.
