Abstract

In the technology industry, metal raw materials such as steel and aluminum have an important role in the production process, as so far there is no metal that cannot be joined by welding. Metal Inert Gas (MIG) welding method is a gas arc welding that uses a welding wire as well as an electrode. In the Metal Inert Gas (MIG) welding process, the heat from this welding process is generated by a welding arc formed between the wire electrode and the workpiece. The purpose of this study was to determine the tensile strength of the welding results in the connection process with Metal Inert Gas (MIG) against aluminum (Al) 5083 series 6 mm thick, the welding was carried out with various current strength treatments, namely 120 A, 130 A, 140 A. and Argon gas discharge 5 lt/minute, 10 lt/minute, 15 lt/minute in each welding process. This research is useful to know and understand about the analysis of the welding process on aluminum 5083 with a thickness of 6 mm with Metal Inert Gas (MIG) welding process using vertical (3 grove) welding techniques. The method used in this study is the analytical method, which is a method for testing by adding different treatments of current and discharge variations of Argon gas during the welding process of the specimen, so that different welding strengths will be obtained in each specimen.

Abstract

The implementation of an automatic lathe, utilizing hydraulic drive and PLC programming, stands as a significant advancement in industrial engineering aimed at augmenting productivity while circumventing additional labor requirements. Through meticulous research, it was discerned that the predominant issue plaguing the production process was the occurrence of stoppages due to irregular or unstable dimensions in the output, particularly concerning the Item Bush K0JA Left. Employing methodologies such as SIPOC analysis and the 4M framework revealed that the root cause primarily stemmed from machine-related factors, exacerbated by fluctuations in the installation, resulting in misalignments and subsequent dimension inaccuracies. Addressing this, a targeted intervention involving the addition of locking bolts to the material fixture mitigated the stoppage occurrences significantly, with the operator rectifying positioning irregularities on average 1200 minutes per month. This intervention not only enhanced operational efficiency but also yielded tangible cost savings, amounting to Rp 578,000 monthly or Rp 6,936,000 annually, attributed to the prevention of production downtime. The implications of this study underscore the importance of proactive measures in streamlining manufacturing processes, thereby optimizing resource utilization and economic viability. Further research avenues could delve into the optimization of maintenance protocols for automated machinery and the exploration of advanced sensor technologies to preemptively detect dimensional inconsistencies, thus bolstering overall production resilience and efficacy. Highlight: Advanced machinery integration boosts manufacturing efficiency. Root cause analysis reveals process optimization insights. Cost savings demonstrate practical impact of production enhancements. Keywoard: Automatic lathe, Industrial engineering, Productivity enhancement, Dimensional accuracy, Cost savings

Abstract

This study presents the design and structural verification of a compact meatball-forming machine that integrates an Arduino Uno–based operator protection system. A redesigned 500×500×1011 mm frame made of 20×20×1.5 mm hollow steel was modeled in SolidWorks 2024 and evaluated using finite element analysis (von Mises stress, displacement, strain, and safety factor) under an applied load representing a 30 kg operating condition. To reduce assembly complexity, two alternative concepts were assessed using Design for Assembly (DFA), and the most efficient configuration was selected for detailed development. The safety subsystem employs an HC-SR04 ultrasonic sensor facing the operator zone; when the detected distance falls below 10 cm, the controller triggers a warning indicator and enables protective control actions. The final concept achieved higher DFA efficiency (18%) than the initial concept (16%) while reducing material use and overall footprint. Structural simulations indicate a peak von Mises stress of 163.6 MPa, below the 250 MPa yield strength of ASTM A36 steel, a maximum displacement of 1.002 mm, and a minimum safety factor of 1.528, confirming adequate stiffness and margin against yielding. The proposed design combines adjustable forming via an iris mechanism with servo-driven cutting to improve process consistency while embedding real-time proximity sensing to enhance occupational safety.

Abstract

General Background: Aerodynamic characteristics play an important role in vehicle performance because air resistance directly affects fuel consumption and maximum speed. Specific Background: Winglet bumpers and rear spoilers are commonly applied aerodynamic devices intended to regulate airflow around vehicles and reduce drag. Knowledge Gap: Although aerodynamic devices have been widely studied, limited experimental evidence directly compares the combined application of bumper winglets and rear spoilers on MPV-type vehicles under controlled wind tunnel conditions. Aims: This study aims to analyze the effect of bumper winglets, rear spoilers, and their combination on air drag acting on an MPV model. Results: Experimental testing was conducted in a wind tunnel using wind speed variations of 7 m/s, 8.5 m/s, and 10 m/s under four configurations: without modification, winglet bumper, rear spoiler, and combined modification. The results show that all aerodynamic modifications reduced drag force and drag coefficient compared with the unmodified model. The combined configuration produced the best result, achieving the largest drag coefficient reduction of 38% at 8.5 m/s. Novelty: This study directly compares individual and combined aerodynamic modifications on an MPV prototype using controlled wind tunnel testing. Implications: The findings indicate that the combined use of bumper winglets and rear spoilers offers a practical aerodynamic strategy for reducing drag and improving high-speed vehicle efficiency. Keywords: Aerodynamics, Drag Coefficient, Winglet Bumper, Rear Spoiler, Wind Tunnel Key Findings Highlights The combined configuration generated the lowest measured air resistance. The largest reduction was recorded at 8.5 m/s. Airflow became more stable with smaller wake formation behind the vehicle.
