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 investigates the impact of coolant types (water coolant, cutting oil, and air blow) and rotational speeds on machining outcomes for stainless steel SUS 304 using insert tools on CNC lathe machines. Conducted at PT. WIDJAYA TEKNIK ENGINEERING, a manufacturing company, the research employs experimental methods alongside literature review and field observations. Results reveal significant effects of rotational speed on coolant efficacy, influencing production metrics such as dimensional accuracy, machining time, and surface finish quality. Notably, cutting oil demonstrates superior performance over air blow coolant at specific speeds. These findings provide valuable insights for optimizing coolant selection and machining parameters, thereby enhancing production efficiency and product quality in machining processes. Highlights: Experimental Study: Investigating coolant types and rotational speed on machining outcomes. Optimizing Production: Enhancing efficiency and quality through coolant and speed optimization.

Abstract

HHO merupakan energi alternatif berbentuk gas yang dapat digunakan sebagai bahan bakar campuran motor bakar, gas HHO dapat dihasilkan dengan proses elektrolisis air. Penggunaan gas HHO sebagai bahan bakar campuran sangat jarang dilakukan bagi para pengguna kendaraan bermotor, penelitian ini dilakukan pada mesin sepedah motor tipe motor bakar bensin 110 cc. bahan bakar percobaan yang digunakan adalah bahan bakar Oktan 90 dan Oktan 92, pada bahan bakar oktan 90 pada putaran mesin 5500 RPM dengan campuran variasi gas sebesar 50 ml/min menghasilkan daya sebesar 5,24 HP. penambahan gas sebesar 100 ml/min pada putaran mesin yang sama terjadi peningkatan menghasilkan daya sebesar 5,48 HP. Sedangkan pada bahan bakar oktan 92 pada putaran mesin 5500 RPM dengan campuran variasi gas sebesar 50 ml/min menghasilkan daya sebesar 3,66 HP. penambahan gas sebesar 100 ml/min pada putaran mesin yang sama terjadi peningkatan menghasilkan daya sebesar 5,12 HP semakin besar tenaga yang dihasilkan pada mesin semakin irit kosumsi bahan bakar, gas HHO sebagai campuran dapat menaikkan tenaga mesin dan menghemat bahan bakar namun pada putaran variasi gas terdapat penurunan tenaga, produksi gas yang kurang maksimal dapat mempengaruhi penurunan mesin,

Abstract

This community service programme aimed to enhance the competencies of vocational high school students in East Java through Computer-Aided Design (CAD) training for Appropriate Technology (AT). Held on 13 June 2025 at the Mechanical Engineering Study Programme, Universitas Muhammadiyah Sidoarjo (Umsida), the activity was part of the Institutional Community Service Grant initiative. A total of 20 students from four partner schools participated, with each school sending five representatives. The training focused on developing students’ technical skills in designing AT products using CAD software and simulating basic fluid mechanics relevant to product development. Expert instructors, certified by the National Professional Certification Board (BNSP), delivered hands-on sessions to ensure strong practical learning outcomes. The results showed significant improvements in students’ technical abilities in CAD-based product design, a better understanding of engineering concepts, and greater readiness to apply these skills in industry-related contexts. This programme represents a strategic effort to bridge the gap between vocational school graduates’ competencies and industry demands, while also fostering innovation and the potential for technology-based entrepreneurship.

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.
