Industry 4.0 is a digitalization trend that can provide a competitive advantage to companies. A way to get in the digitalization process is through process automation and data connectivity applied within a company. PT SKI, a subcontract manufacturing company that processes metal products according to customer request, seeks to implement process automation. This is seen as an alternative solution to address the quality fluctuations resulting from human error in the plating process. Plating is a metal coating process aimed at increasing corrosion resistance on metal and enhancing the aesthetic value of workpieces. Currently, PT SKI’s plating process relies on human labour to move workpieces and calculate processing time for each bath. To understand the existing process conditions and identify potential improvement, the engineering design method was reworked to adjust when designing this automation system. This method follows stages that imitate the development of prototyping while evaluating the fulfillment of each requirement. The stages are defining the problem, generating alternative concepets, evaluating and selecting concept, detailing the design, testing, and evaluating performance. The designed automation system will consist of PLC-based hoist and cranes, with HMI to facilitate monitoring during implementation. The resulting system design is divided into two modes: automated and manual. The manual system can be used by operators when there is a need to repeat a specific process or when the automated process cannot be executed. Meanwhile, the automated system can serve as a reference for the company to help reduce on-site operators and increase productivity by minimizing manual work processes. The HMI also facilitates operators in monitoring the ongoing production process and provides the capability to intervene in the automated process.
