Abstract

This research aims to develop an effective and reliable work safety protection system based on Arduino Uno. The system is designed to detect hazards in the workplace, such as suspicious movements that may cause accidents for industrial workers. Arduino Uno is used as the brain of the system, and sensors connected to the microcontroller serve as input devices that detect actions not in accordance with safety procedures. When the sensors detect a hazard, Arduino Uno will activate an alarm and automatically take the necessary control actions. This research involves programming the Arduino Uno, selecting the appropriate sensors, hardware integration, and thorough system testing. The developed system is expected to enhance workplace safety and provide better protection for workers. System testing is conducted using a simulated work environment that depicts different hazard scenarios. The test results show that the Arduino Uno-based work safety protection system functions as expected. The installed sensors accurately detect hazards such as excessive temperature, fire, toxic gases, excessive vibrations, and unwanted movements in the work area. Arduino Uno receives signals from these sensors and quickly responds by activating alarms and taking appropriate protective actions. Interpretation of the test results indicates that the developed system can effectively help identify potential hazards and provide the necessary protection for workers in the manufacturing industry

Abstract

Resistance spot welding (RSW) menjadi salah satu pilar utama dalam manufaktur otomotif, khususnya dalam perakitan badan kendaraan. Studi ini menyelidiki kinerja dan efisiensi dari sistem prototipe resistance spot welding yang baru dirancang untuk perakitan badan kendaraan. Metodologi penelitian melibatkan pengujian dan evaluasi yang ketat untuk mengukur efektivitas sistem dalam hal kualitas las, dan kekuatan. Berbagai parameter seperti arus pengelasan, waktu, dan gaya elektroda secara sistematis diperiksa untuk mengoptimalkan proses pengelasan. Selain itu, analisis komparatif dilakukan antara sistem RSW prototipe dan metode pengelasan konvensional untuk menilai superioritasnya dalam hal kinerja dan efektivitas biaya. Temuan ini memberikan wawasan berharga tentang kelayakan dan potensi keuntungan mengadopsi teknologi RSW prototipe dalam manufaktur otomotif, membuka jalan bagi peningkatan produktivitas dan kualitas dalam proses perakitan badan kendaraan.

Abstract

penggunaan stainless steel sebagai bahan peralatan pangan. Stainless steel dipilih karena kelebihannya, seperti ketahanan terhadap korosi, tidak bereaksi dengan makanan, dan mudah dibersihkan. Pemilihan material yang tepat ini sangat penting karena dapat memengaruhi kualitas dan keamanan produk pangan, yang pada akhirnya berdampak pada kesehatan konsumen dan keberlanjutan industri pangan. Lokasi dampak treatment mencakup rumah tangga atau skala domestik, serta potensi penerapannya dalam skala yang lebih besar di industri pangan. Dampak penggunaan stainless steel pada peralatan pangan terutama terkait dengan peningkatan standar kebersihan dan keamanan dalam pengolahan makanan di rumah tangga. Ini juga berkontribusi pada peningkatan kualitas hidup masyarakat secara keseluruhan dengan memastikan produk pangan yang lebih aman dan berkualitas. Secara keseluruhan, PKM ini bertujuan untuk memperkuat pemahaman dan penerapan teknologi tepat guna yang mendukung keamanan pangan, menjaga kualitas produk, serta mempromosikan lingkungan yang lebih sehat dan berkelanjutan melalui penggunaan material yang tepat.

Abstract

To ensure the quality of welded joints in the hull area, welding testing is very important and must be carried out. But unfortunately, currently the quality testing process of welded joints was still limited to penetrant tests and lime tests. The purpose of this study was to obtain a portable welding testing machine that was able to obtain fairly accurate test results on hull welding defects using a vacuum system. The research method is experimental by involving data collection through field experiments, testing is carried out with the resulting weld defect research subjects and the length of testing time on 1G and 3G position welding. The results of the study by compared tests among Welded Vacuum Testing (WVT) machines, Magnetic Particle tests (MP), and Penetrant Tests (PT). The three experiments detected leaking weld defects, spark sparks, pinholes, overlaps, and undercuts. For test results with machines made, welding defects that were successfully detected were leaks in the 1G position welding workpiece and undercut in the 3G position welding workpiece. Air bubbles at a vacuum pressure of 0.2 bar are detected, meaning that there is a defect in the welded joint. This tool can be used in bilge testing.

Abstract

This study aims to analyze the types and causes of welding defects that occur during Shielded Metal Arc Welding (SMAW) using different electrodes in the 2G position on ST 37 steel. The research was conducted by students of the Diploma III Industrial Agro-Manufacturing Engineering Study Program at Politeknik ATI Makassar using both qualitative and quantitative approaches. A total of 10 welded samples were visually examined and tested using the liquid penetrant method to detect surface defects. The analysis employed the Fault Tree Analysis (FTA) method with a deductive approach to identify the top events representing major defect types, trace their root causes through the fault tree structure using AND and OR logic gates, and analyze the relationships among contributing factors. The results revealed five dominant defect types—spatter, stop-start, surface undercut, root concavity, and blow hole—which accounted for 61.7% of all detected defects. These defects were primarily caused by technical factors, including unstable arc control, improper welding angles and travel speeds, and poor cleanliness of electrodes and materials. Other defects, including root undercut, cold lap, excessive penetration, pin hole, and porosity, also affected weld quality. Based on the FTA findings, corrective actions were recommended, including operator retraining, proper parameter adjustment, equipment maintenance, and enhanced supervision to improve overall weld quality.
