Abstract

OLED display has the advantages of self-illumination, wide viewing angle, fast response, small size, small weight, flexibility. It is a huge breakthrough in the field of display technology, and enhances the visual enjoyment and on-the-spot experience of people. With the rapid development of science and technology, the combination of OLED and robot has attracted attention from most of the fields. In this paper, the working principle, advantages and main application fields of OLED devices are introduced, and a detection robot with OLED is designed. The detection robot can accurately control the speed of the motor and the angle of the steering gear within a distance of 1,000 meters, and receive the images from airborne cameras in real time.

Abstract

Ensuring handrails structural integrity and safety in industrial hopper systems is crucial for worker protection and operational efficiency. This study investigates handrail systems design, stress analysis, and safety factors using Finite Element Analysis (FEA) via SolidWorks. Observations of existing systems revealed deficiencies such as improper welding techniques and unstable mounting, which were addressed through an improved modular handrail design that incorporated standardized dimensions, full-welded joints, and clamped baseplates. The methodology included a comprehensive simulation of the static loads, stress distributions, and deformation patterns validated through physical load testing. Results demonstrated significant improvements, with a reduction in the maximum stress by 25% and deformation by 40%, yielding a safety factor of 1.85. The findings confirm compliance with the industrial safety standards and highlight the robustness of the proposed design. This research contributes to advancing workplace safety through a replicable framework that combines simulation and empirical validation, offering broader applicability to safety-critical industrial components.

Abstract

The global automotive industry demands a workforce that possesses not only technical skills but also the ability to communicate professionally in English. Unfortunately, many high school graduates still struggle to understand technical terms, express ideas professionally, and write work-related reports in English. This community service program aimed to improve the job readiness of students at SMA Chandra Buana through English language training based on the context of the automotive industry. The activity was carried out on January 31, 2025, involving 16 students from grades X and XI IPS. The training covered technical vocabulary introduction, vehicle manual reading, workplace communication simulations, technical report writing, and oral presentations. Evaluation using pre-tests and post-tests showed an improvement in technical English comprehension. In addition, students’ confidence in using English also increased significantly. This program makes a tangible contribution to preparing students for the global job market and emphasizes the importance of English learning based on industrial context at the secondary education level.

Abstract

Kebisingan yang dihasilkan oleh sistem roots blower dalam aplikasi industri sering kali mencapai tingkat tekanan suara tinggi (120–135 dB), yang dapat mengganggu kenyamanan dan berpotensi menyebabkan gangguan kesehatan. Permasalahan utama terletak pada keterbatasan performa silencer konvensional dalam meredam kebisingan, serta kurangnya pendekatan desain yang efisien dan ekonomis melalui simulasi numerik. Studi terdahulu menunjukkan bahwa pemanfaatan material berpori seperti Rockwool dan pendekatan berbasis Finite Element Method (FEM) dapat meningkatkan performa akustik silencer, namun sebagian besar aplikasi masih terbatas pada sektor otomotif dan HVAC. Penelitian ini bertujuan untuk menganalisis dan membandingkan performa akustik dua model silencer roots blower dengan model eksisting berbahan SUS 304 dan model usulan yang mengombinasikan SUS 304 dengan lapisan Rockwool, melalui simulasi numerik menggunakan perangkat lunak COMSOL Multiphysics versi 6. Metode penelitian meliputi perancangan geometri, penerapan properti material, pengaturan domain akustik, pembuatan mesh berbasis physics-controlled, dan simulasi dalam domain frekuensi menggunakan modul Pressure Acoustics dan Poroacoustics. Hasil simulasi menunjukkan bahwa model silencer usulan mampu mereduksi tingkat kebisingan secara signifikan, dengan penurunan Sound Pressure Level (SPL) dari 120 dB menjadi 80 dB di outlet, atau sekitar 40% lebih rendah dibandingkan model eksisting. Efektivitas ini disebabkan oleh kombinasi desain geometri yang lebih kompleks dan kemampuan absorpsi tinggi dari Rockwool. Simulasi juga memberikan visualisasi distribusi tekanan suara secara detail yang mendukung evaluasi performa desain. Kesimpulannya, pendekatan simulasi berbasis COMSOL Multiphysics efektif untuk mendukung pengembangan silencer dengan performa akustik yang lebih baik, efisien, dan aplikatif dalam lingkungan pendidikan vokasi serta industri lokal.

Abstract

This study utilizes SolidWorks software to thoroughly examine the structural layout and static load simulation of a temporary platform and ladder in an adsorbent chamber. SolidWorks, a computer-aided design (CAD) and computer-aided engineering (CAE) software, offers robust tools for 3D modeling, simulation, and analysis, making it ideal for this type of structural assessment. Finite element analysis (FEA), a simulation model within SolidWorks, is employed to determine stress distribution and safety factors. The results demonstrate the platform's maximum stress at 198.65 MPa, below the yield strength of ASTM A36 Steel, leading to a safety factor of 1.3. These findings validate the design's safety and reliability for industrial use.
