Abstract

Pressure vessels are critical components in the energy industry, used to store and process high-pressure fluids. The structural reliability of these vessels plays a pivotal role in ensuring operational safety and system efficiency. This study aims to analyze the design and reliability of pressure vessels using both numerical and experimental approaches to optimize performance and enhance safety factors. The numerical method was conducted through Finite Element Analysis (FEA) using ANSYS software to evaluate stress distribution, stress concentration, and potential failure modes under various operational load scenarios. Meanwhile, the experimental method involved hydrostatic pressure testing, strain measurements using strain gauges, and displacement analysis to validate the numerical simulation results. Data were collected from simulations and laboratory experiments, then analyzed quantitatively by comparing key parameters such as stress distribution, deformation patterns, and safety factors against industry standards. The results indicate that combining numerical and experimental approaches improves the accuracy of pressure vessel behavior predictions, enables more efficient design optimization, and enhances structural reliability. In conclusion, the methods applied in this study can serve as a reference for developing safer, more efficient pressure vessel designs that comply with industrial standards, thereby supporting improved safety and operational efficiency in the energy sector.

Abstract

When producing a perfect product, design process namely 2D modeling and 3D drawing, are closely related. The purpose of this study is to design a 3D model of a gun mastering machine product as a fan drive using CAD applications. The method of this study is decision data on API production (analytical product inspection). Measurement of sterling machine degradation using CPK (deviation) received results of -0.97, -0.22, 0.86, 0.11, 0.11 between zero and what indicates this specification. On average, the results of the stirling fluid fluorescent agent measurement are red numbers indicating that the survey dimensions are absent, especially from the basic dimensions of point 4, with samples 2, 3, and 5 exceeding the specified tolerance limits.

Abstract

Transformator merupakan komponen penting dalam sistem kelistrikan, namun proses pembuatan transformator secara manual masih memiliki keterbatasan dari sisi efisiensi dan akurasi jumlah lilitan. Penelitian ini merancang dan membangun mesin penggulung lilitan kawat transformator otomatis berbasis Arduino Uno dengan kontrol motor stepper melalui driver L298N, serta antarmuka LCD 16x2 untuk menampilkan jumlah lilitan. Sistem ini dilengkapi push button sebagai penentu jumlah lilitan dan potensiometer untuk mengatur kecepatan putaran motor. Hasil pengujian menunjukkan bahwa mesin ini mampu bekerja dengan tingkat presisi tinggi, dengan selisih jumlah lilitan hanya 1–3 lilitan pada setiap pengulangan dan perbedaan kecepatan motor stepper sebesar 2–3 RPM. Dengan demikian, mesin ini dapat meningkatkan efisiensi produksi transformator serta mengurangi potensi kesalahan manual. Penelitian selanjutnya disarankan untuk menambahkan mekanisme penggerak kawat otomatis agar distribusi lilitan lebih merata.

Abstract

One of the activities in the supply chain system in the motorcycle industry is the process of sending components or spare parts from vendors to motorcycle assembly plants. Delivery of spare parts using the respective vendor's fleet. Along with the increase in market demand, demand for components from vendors has also increased. This has an impact on increasing the number and frequency of fleets entering the factory area; besides that, there is also an increase in transportation costs from Vendors. This study aims to improve efficiency in the number, frequency, and cost of fleet transportation by using the VRP (Vehicle Routing Problem) approach. To get optimal results, the PSO (Particle Swarm Optimization) method was used by utilizing the MATLAB 2020 software. This research involved 40 vendors, logistics partners, and motorcycle assembly factories. The results of this study showed better results, namely, before the research was carried out, the number of fleets was 40 units, and the delivery frequency was 40 times, with a total shipping cost of IDR 2,769,330. Meanwhile, after conducting research using the PSO optimization method, it was obtained that the number of delivery frequency fleets was 8 times with a total shipping cost of IDR 2,679,113.

Abstract

Global climate change driven by greenhouse gas (GHG) emissions, particularly carbon dioxide (COâ‚‚), has become the greatest challenge of this century. At the same time, the accumulation of plastic waste has emerged as a massive environmental crisis. This paper examines the potential utilization of plastic waste into paving blocks as a carbon mitigation strategy and a waste management solution. This approach not only reduces the volume of plastic waste in the environment but also has the potential to lower the carbon footprint of conventional construction material production and contribute to the circular economy. The analysis involves a comparison of the carbon footprint between plastic-based and conventional paving blocks, as well as an estimation of the carbon mitigation potential at various scales of implementation. The findings indicate that material substitution and the incorporation of plastic into durable products offer significant contributions to emission reduction and foster sustainable development.
