Abstract

Power generation is an industry that is essential to sustain daily life and competes with generator set distributors. The product service system of distributors must be improved to survive the competition. This research aims to develop tools for benchmarking the product service system of generator set distributors. Benchmarking identifies gaps between a product and other competitors’ products. In this work, a product service system board is used to visualize the current product service system of a generator set distributor. A PPIAF framework and a SERVQUAL framework are adapted to assess product performance and service quality, respectively. AHP is used as weighting method. The survey results provide ideas for improving the current product service system of generator set distributors. Further studies must use detailed measure weighting methods and implement the product service system board to assess service quality.

Abstract

In today's industrial landscape, companies must enhance operational efficiency, productivity, and sustainability while integrating traditional Lean manufacturing principles with Industry 4.0 technologies like IoT, AI, and data analytics. Despite the potential benefits, there is a significant gap in understanding and implementing Lean 4.0. The Lean 4.0 Workshop aims to provide a comprehensive and practical understanding of how Lean principles can be integrated with Industry 4.0 technologies to enhance industrial performance and sustainability. The event, held at Pusat Industri Digital (PIDI) 4.0, attracted representatives from many notable companies. This paper focuses on the benefits this event provides to the community. The workshop presentations disseminate ongoing research as well as theoretical and practical concepts in various areas of Lean 4.0. The exhibition of industrial tools and processes allows participants to become more familiar with advanced technologies and their practical applications. Considering the event's performance, the Lean 4.0 workshop was a success, with over 80 participants showing great interest and actively participating, along with effective and efficient knowledge sharing. Based on the satisfaction survey, 42.9% of respondents were very satisfied with the workshop, and 64.3% found it met their expectations, though not to the fullest extent.

Abstract

PT. XYZ is a company that produces electrical components, they make a product based on an engineer to order (ETO). PT. XYZ find the changeover time in the testing process is very high and still follow the time in the old factory. The focus of this research is to reduce changeover time and standardize the process. In this research, Single Minute Exchange of Dies (SMED) is a method that used in order to reduce the changeover time. Started by observing the entire changeover process from the process after the panel is tested on Post F to loading a new panel for testing on Post F. Suggested improvement proposals that can be made immediately will be implemented directly in the process. For the internal process, the improvement activities carried out are to make the activities run parallel. Then, for external activities, the improvement activities carried out are to make the activities run in parallel and change the work procedures at Post F. Through 5S implementation will improve the speed changeover process. Through this improvement it can reduce the change over time by 54% and increase the number of panels that can be tested to 6 panels per work shift.  PT. XYZ merupakan perusahaan yang memproduksi komponen listrik, mereka membuat produk berdasarkan Engineer-To-Order (ETO). PT. XYZ menemukan waktu pergantian pada proses pengujian sangat tinggi dan masih mengikuti waktu di pabrik lama. Fokus penelitian ini adalah untuk mengurangi waktu pergantian dan menstandardisasi proses. Dalam penelitian ini, Single Minute Exchange of Dies (SMED) merupakan metode yang digunakan untuk mengurangi waktu pergantian. Dimulai dengan mengamati seluruh proses pergantian dari proses setelah panel diuji pada Post F hingga mencari panel baru untuk pengujian pada Pos F. Usulan perbaikan yang dapat segera dibuat akan diimplementasikan langsung dalam proses. Untuk proses internal, kegiatan perbaikan yang dilakukan adalah membuat kegiatan berjalan sejajar. Kemudian , untuk kegiatan eksternal, kegiatan perbaikan yang dilakukan adalah membuat kegiatan berjalan paralel dan berputar prosedur kerja di Pos F. Melalui penerapan 5S akan meningkatkan kecepatan proses pergantian . Melalui perbaikan ini dapat mengurangi waktu pergantian sebesar 54% dan meningkat jumlah panel yang dapat diuji menjadi 6 panel per shift kerja .

Abstract

Road accidents remained a significant global concern, causing loss of life and economic damage. To mitigate this issue, the automotive industry has increasingly invested in Advanced Driver Assistance Systems to enhance vehicle safety. This research presented a Driver Assistance Collision Warning System that incorporated kinematics and perception algorithms to improve collision prevention. The system utilized a LIDAR sensor to capture real-time data regarding the distance to the vehicle in front of it. This data was integrated with an Arduino microcontroller to compute the relative speed and time of collision. Upon detecting a collision risk, the system triggered a warning mechanism, which included an audible alert provided by a buzzer and a visual warning displayed on the head-up display. The system integrated kinematics algorithms, which processed sensor-read values to generate real-time decisions utilizing a specific threshold time to collision, and perception algorithms relied on Fuzzy Logic to handle uncertainty and improve accuracy. Validation was conducted through integration, system, and acceptance testing, demonstrating reliable synchronization of algorithms and accurate operation in real-world environments. The results showed that the system achieved a collision risk detection accuracy of ±5 cm within five different environmental factors. These findings confirmed the system's potential as a reliable solution for real-world collision prevention.
