Abstract

The portable laser engraving system developed in this study integrates an APM32F103 microcontroller, external flash memory (25Q128JV), and an FSC-BT986 Bluetooth module with an Android-based engraver application. The system is designed to address limitations of bulky and costly commercial engravers by offering a compact, low-cost, and wireless alternative for educational laboratories and small-scale manufacturing. Mechanical and electronic subsystems were designed and fabricated using a knockdown frame structure and 3D-printed components. Performance evaluation included functionality testing, wireless communication stability, motion accuracy, and engraving capability on wood, MDF, acrylic, and synthetic leather. The results show stable Bluetooth communication within an effective range of 8 m, an average motion accuracy error of 0.82%, and engraving depths ranging from 0.28–0.45 mm depending on material and laser parameters. The proposed configuration demonstrates technical advantages in wireless stability, portability, and ease of use compared to conventional wired microcontroller-based laser engravers.

Abstract

Rejosari Village, Pakis, Magelang is a center for blacksmithing enterprises, where the majority of residents earn their livelihoods in the blacksmith industry, both as employers and workers. The products produced in the blacksmithing process include hoes, sickles, grass sickles, machetes, knives, spoons, forks, plates. The production process is still carried out manually using simple equipment and has not yet implemented good manufacturing practices. There are still potential workplace hazards, and the understanding and application of OSH aspects remain far from disciplined. The potential hazards found as high heat, respiratory problems. These hazards are exacerbated by work behaviors that have not properly applied OSH standards. Through the implementation of community service activities on management and application, an improvement in understanding of OSH standards has been achieved among both employers and workers. Consequently, work quality and productivity will automatically increase in line with compliance with work behavior based on OSH standards.

Abstract

This study aims to design and develop a prototype of a fire suppression system for electric bus bateery compartments to mitigate the risk of thermal runway, shich can lead to catastrophic battery fires. The desin integrates an Arduino uno base controller eith themal and MQ-2 smoke sensors, connected to a fire suppression installation utilizing dry powder as the extinguishing agent. Testing results demonstrate that the system operates responsively and systematically the cooling fa activates 40℃ for thermal management, while the emergency fire suppression via a solenoid valve triggers automatically when the temperature reaches 60℃ or smoke density hits 200 ppm. The primary advantage of this prototype lies in its multi layered protection, combining proactive battery temperature conditioning with an automated fire extinguishing mechanism. This system significantly enhances the operational safety standards for electric vehicles by providing a reliable defense against battery relates hazards.
