The International Journal of Mechanical Engineering Science and Technology (IJOMEST) is a peer-reviewed, open-access scientific journal published by the Asosiasi Diseminasi Rekayasa dan Inovasi Teknologi (ADRIT), Indonesia. The journal serves as a platform for researchers, academics, engineers, and practitioners to share original contributions in the field of mechanical engineering and related disciplines. All manuscripts are published in English and issued three times per year, in January, May, and September. IJOMEST welcomes original research articles, review articles, and technical papers that advance knowledge in mechanical engineering and smart technology. The scope of the journal covers, but is not limited to, the following areas: • Manufacturing Engineering: machining processes, CNC technology, additive manufacturing, precision engineering, and production systems • Materials Engineering: mechanical properties of materials, composite materials, material characterization, heat treatment, and failure analysis • Energy Systems and Thermal Engineering: heat transfer, thermodynamics, renewable energy, solar energy, biomass energy, drying technology, and energy efficiency • Fluid Mechanics and Hydraulics: computational fluid dynamics (CFD), flow analysis, hydraulic systems, and pneumatic systems • Design and Structural Engineering: machine design, stress analysis, finite element analysis (FEA), structural integrity, and fatigue • Mechatronics and Automation: robotics, control systems, sensors and actuators, and industrial automation • Smart Technology and Industry 4.0: Internet of Things (IoT) in manufacturing, artificial intelligence applications in engineering, digital twin technology, and smart manufacturing • Maintenance and Reliability Engineering: condition monitoring, predictive maintenance, vibration analysis, and failure mode analysis • Environmental and Sustainable Engineering: green manufacturing, lifecycle assessment, emission reduction, and sustainable energy systems
