In addition to peer-reviewed original research papers, the Editorial Board welcomes original research reports, state-of-the-art reviews, and communications in the broadly defined field of recent engineering science and technology. <strong>RiESTech</strong> covers topics contributing to a better understanding of Engineering Science and Technology, and their applications. <strong>RiESTech</strong> is concerned with scientific research on Industrial and Manufacturing Engineering, Mechanical Engineering, Material Science and Nanotechnology, Chemical Engineering, and Bioengineering, Electrical and Electronic Engineering.</p> <p><strong>The scope of RiESTech includes a wide spectrum of subjects namely</strong></p> <p><strong>Industrial and manufacturing engineering </strong>(Manufacturing Processes, Manufacturing Technologies, Design and Assembly, Supply Chain and Operations, Human Factors and Ergonomics, Robotics and Automation, Measurement and Quality Control)</p> <p><strong>Mechanical engineering </strong>(Solid Mechanics and Structural Analysis, Thermal and Fluid Systems, Sustainability and Environmental Performance, Control and Automation, Robotics and Mechatronics, Machine Design)</p> <p><strong>Material science and nanotechnology </strong>(Advanced Materials Science and Metallurgy, Nanostructured Materials, Nanotechnology Applications, Nanophysics and Nanoelectronics, Computational and Molecular Nanotechnology, Advanced Fabrication Techniques, Ceramic and Inorganic Materials; Electronic-Magnetic Materials, Materials Characterization, Polymers and Nanocomposites)</p> <p><strong>Chemical engineering, and bioengineering </strong>(Thermodynamics, separating processes, transport phenomena, catalysts, reaction engineering, polymers and colloids, biotechnology, process design and simulation and control)</p> <p><strong>Electrical and electronic engineering </strong>(Communication Technologies, Signal Processing, Power and Energy Systems, Control Systems, Electronics and Semiconductor Technologies, Computer and AI Applications, Electrical Machines and Apparatus)</p> MBI en-US Recent in Engineering Science and Technology 2985-8321 https://mbi-journals.com/index.php/riestech/article/view/118 <p>The use of low-cost sensors controlled by open-source microcontrollers (Arduino, ESP32) is investigated in this study not only to measure electrical, thermal, and magnetic values ​​but also to investigate intrinsic material properties such as thermal conductivity and magnetic strength. Four sensors are used in this study such as SS49E, MAX6675, ACS712, and HMC5883L. Their performance is evaluated in monitoring a carbon rod subjected to 29.9 V DC current and the measurement results are displayed on a 20x4 I2C LCD and stored in CSV format on an SD Card. The MAX6675 thermocouple sensor shows the most stable and reliable results for surface temperature measurement, which is supported by reference multimeter readings. However, the use of multiple sensors simultaneously reveals interference issues, indicating the need for electrical isolation or signal multiplexing in future designs. This study contributes to the advancement of affordable open-source instrumentation as a viable alternative to commercial measurement tools, emphasizing the shift from raw signal acquisition to meaningful property computation.</p> Nazhmi Fadhila Filia Solagratia Takasumiang Hanandira Wistikhirana Yudha Dewangga Rafi Pradaya Andareska Agus Edy Pramono Iman Setiyadi Copyright (c) 2026 Recent in Engineering Science and Technology 2026-04-25 2026-04-25 4 2 59 72 10.59511/riestech.v4i2.118 https://mbi-journals.com/index.php/riestech/article/view/126 <p><span class="fontstyle0">This study investigates the application of structural reliability methods in risk-based inspections (RBIs) for subsea crude oil pipelines. Given the increasing reliance on submarine pipeline infrastructure in offshore oil and gas operations, maintaining its integrity is critical to operational safety and environmental protection. This study uses inspection data from smart pigging operations carried out in 2020 and 2024 on 28.7 km of 12-inch underwater pipes. Using API RP 581 (2020) and First-Order Second-Moment (FOSM) structural reliability theory, this study quantitatively assesses the probability of failure (PoF) and the consequence of failure (CoF). Results showed active internal corrosion, with pitting corrosion identified as the dominant degradation mechanism. Risk projections from 2024 to 2030 reveal unacceptable levels of risk in 2030 if mitigation strategies are not implemented. Based on the financial impact and business risk thresholds, a tailored inspection and maintenance strategy is proposed. These findings support the optimization of inspection intervals and highlight the importance of corrosion control measures such as routine pigging and inhibitor injections.</span></p> Muhammad Iqbal Johny Wahyuadi Soedarsono Gusti Verhan Pratama Copyright (c) 2026 Recent in Engineering Science and Technology 2026-04-28 2026-04-28 4 2 73 86 10.59511/riestech.v4i2.126
