Delivering defective products to customers is a consequence of the rapid production model implemented by most fast moving consumer goods companies. PT. Paragon Technology and Innovation, which is a local company engaged in the cosmetics sector, is also experiencing this problem. One of the types of defective products found in the TUP-06 container line at the Jatake 2 factory owned by PT. Paragon Technology and Innovation is a secondary packaging mismatch with the planned product packaging schedule. This discrepancy raises customer complaints, so there is a risk of lowering the brand value of the product portfolio of PT. Paragon Technology and Innovation. The inspection system designed aims to prevent this risk by separating defective products from the packaging line, so they are not distributed to customers. The control sub-system is one component of the designed system that controls all activities that involve interaction with the cartoning machine such as the acquisition of iteration signals to detect the packaging speed of the machine and trigger the cartoning machine refusal mechanism to separate defective products from the packaging line. The method used in the design of the inspection system is capstone design, which is a system design that is rooted in user needs. User requirements that must be met specifically by the control sub-system are reading iterations of packaging movement and triggering repellents on cartoning machines with a duration of less than 400 ms, as well as providing light indicators with an intensity range of 65 cd to 230 cd and sound with an intensity of more than 70 dB. The first two specifications are derived from the maximum packaging speed of the cartoning machine, which is 75 products per second. The other two specifications are derived from a comparative study of the condition of the Jatake 2 plant and several standard recommendation documents for the use of indicators as a warning tool. To realize these specifications, the control sub-system is divided into three separate parts, namely the control unit, signal acquisition, and trigger rejection. The control unit part serves to communicate the rhythm of the cartoning machine to the iv processing unit. The implementation of the control unit is the Arduino NANO microcontroller. The selection of these devices has taken into account the frequency of the microcontroller and the load of instructions that must be executed in a relatively short time. The study has been carried out by making a test code script and breaking it down to the smallest instruction unit in assembly language. The signal acquisition section functions to condition the signal from the electrical system of the cartoning machine to match the specifications of the control unit. The implementation of the signal acquisition part is a voltage divider circuit. The selection of the circuit concept has taken into account the durability and response speed of the device. The selection study was conducted by comparing the datasheets of several available device options. The repellent trigger part functions to control the repellent installed on the cartoning machine. The implementation of the reject trigger section is a 5 VDC relay device. The selection of these components has taken into account the modularity and speed of device response. The selection study was conducted by comparing the datasheets of several available device options. The test results show that the time required by the control sub-system in conveying the rhythm of the cartoning machine to the processing unit for each iteration is on average 36.4 ms and the time required by the control sub-system to follow up the inspection results varies with a range of approx. 40 ms to 61 ms. The built-in indicator can light up with a light intensity of about 117 cd and a sound intensity of about 90 dB. This project has a significant contribution to the science of design which involves the analysis of the selection of computing units because it offers a method of assessing the computational performance requirements of computing loads and the science of industrial-scale device design because it uses the basics of calculating industrial operating conditions in its implementation..
