Improvement Desain pada Sistem Pedal Mesin Press Hidrolik untuk Meningkatkan Keamanan dalam Operasional

Ananda Raka Surya M — 2025-06-30

The hydraulic press machine is one of the essential tools in the manufacturing industry, particularly in the automotive sector, to accelerate and simplify the process of forming and assembling metal components with high precision. However, operating the machine using buttons presents several challenges, such as unresponsiveness, operator fatigue, and the risk of workplace accidents. This study aims to improve the efficiency and safety of hydraulic press machine operations by replacing the button system with a pedal system. This research uses a quantitative descriptive approach with literature review and experimental methods in the design process. The research stages include data collection through literature review, component Benchmarking to compile the Bill of Material (BOM), and machine design development using Assembly chart and Operation Process Chart (OPC). The results show that replacing buttons with pedals improves the machine's responsiveness and operator comfort. The ergonomic pedal design allows operators to control the machine more accurately and steadily, making the production process more efficient and consistent. Furthermore, the updated machine design with an enclosed structure enhances protection for internal components and extends the machine’s lifespan. In conclusion, the innovation of replacing the button system with a pedal system in hydraulic press machines successfully improves operator safety.

Analisis Quality Function Deployment (Qfd) Untuk Pengembangan Sistem Electro Pneumatic Berbasis Programmable Logic Controller (Plc) Pada Mesin Semi Otomatis Tester Coding Battery

Chandra Aditya Luhur Wicaksono — 2025-06-30

This research aims to develop a semi-automatic battery voltage testing machine using electro-pneumatic technology controlled by a Programmable Logic Controller (PLC) at PT VARTA Microbattery Indonesia. This machine is designed to enhance the efficiency and accuracy of testing lithium round cell 2/3 AA batteries, which were previously tested manually. The machine development utilizes the Quality Function Deployment (QFD) method, which identifies user needs through interviews and questionnaires, then translates them into technical characteristics within the system. The analysis using the House of Quality (HoQ) showed that the main priorities are testing accuracy, speed, ease of operation, and safety. This system integrates electro-pneumatic components, sensors, and PLC to control the machine's movements, ensuring a more efficient and consistent production process. The results indicate that the implementation of this semi-automatic machine can reduce the testing cycle time and improve battery production productivity.

Habib Aufarizag — 2025-06-30

This study aims to design an optimized 5-Axis Robotic Arm system for Quality Control (QC) applications utilizing infrared sensor technology. The research process involved a comprehensive literature review to explore the latest developments in robotic systems and automation technologies. Benchmarking similar products was conducted to identify strengths and weaknesses as a foundation for innovation. The preparation of the Bill of Material (BoM), Operation Process Chart (OPC), and Assembly Chart (AC) was essential for systematic production planning. The final design was developed using Inventor 2024 software to ensure precision and component compatibility. The results demonstrate that the selection of aluminum materials, servo motors with a lifting capacity of up to 10 kg, Arduino Uno R3, and Pixy Cam significantly enhanced the system’s flexibility, durability, and efficiency. Structural modifications improved the mechanical stability and operational lifespan of the robotic arm. This system is expected to serve as an effective solution to improve the accuracy and speed of Quality Control processes in modern industrial environments.

This research aims to optimize the design of a 6-axis robotic Arm for spray painting processes in the automotive industry. The main problem identified is the complexity of the structure and the presence of non-functional components, which complicate the manufacturing process. Through benchmarking methods, analysis of the Bill of Materials (BoM), creation of an Operation Process Chart (OPC), and Assembly Chart (AC), the design was simplified without reducing its core functionality. Design development was carried out using Autodesk Inventor software to create a more efficient 3D model. An evaluation was conducted on the new design, including a Cost of Goods Manufactured (HPP) analysis to ensure cost efficiency. The research results show that eliminating non-functional parts improves production speed, reduces costs, and maintains the robotic Arm's balance and safety. Thus, the developed robotic Arm is simpler, more effective, and more economical to support increased industrial productivity.

Shelters act as an important transition space for street children to get protection, coaching, and psychosocial reinforcement. The room's design in the halfway house can affect children's behavior, ranging from emotional aspects to social behavior. This article presents a literature review of various recent studies related to the relationship between spatial design and the behavior of street children in the context of shelters in Indonesia. The study stages are carried out systematically using scientific sources from 2019-2024. The review results found that design elements such as layout, natural lighting, ventilation, color selection, and space flexibility significantly impacted comfort, security, and children's participation in social activities. This study emphasizes the importance of a behavior-based design approach to create spaces that are not only functional but also support the holistic recovery and growth of street children.

Wind power generation systems, wind speed has a significant impact on generator performance. Variations in wind speed can affect the reliability, efficiency, and output power of the system. The purpose of this study is to examine the relationship between changes in wind speed and generator performance, including energy conversion efficiency, output current, and output voltage. The study methodology includes actual measurements on a wind turbine-based generation system. The findings show that while higher wind speeds tend to increase generator output power, generator performance decreases drastically at low wind speeds, which can impact the reliability of electricity supply.
