<![CDATA[This research aims to develop a continuous metal detection system for food to prevent metal contamination in food consumed by the public and to determine the performance of a Programmable Logic Controller (PLC) system for controlling a metal detector conveyor. The method employed involves designing a PLC system that integrates a pulse induction metal detector, photosensor, and conveyor system. Functional testing is conducted on each component, followed by an overall performance test of the equipment. The functional testing results indicate that the components used can work properly and normally. The subsequent test is a performance test, which shows that out of 50 food samples tested, including meatballs, spring rolls, lumpia, cenil, and other traditional snacks, the device successfully detected metal in 25 of the food samples.]]>
