Internet of Things-based Analysis of Factory Production Machine Damage Detection System Model Using Case-Based Reasoning Method

Computers are very important in industrial processes because they play a role in the life cycle of the product systems that companies manufacture. Damage to production equipment often occurs due to lack of detailed periodic maintenance, making it difficult for operators and technicians to maintain production machines. Because it still uses a manual approach, the repair time is long and accurate at a high cost. Case-Based Reasoning (CBR), a problem solving technique based on previous experience and applied in the present, is one of the computer science disciplines commonly used by humans to help and facilitate work. CBR is used to find solutions by utilizing or analyzing case data collected previously. In this study to solve the problem by using the CBR method. Case representation, case indexing, case retrieval, case adaptation, and case maintenance are the five goals of CBR in knowledge formation. The process of finding and measuring cases with the greatest closeness is known as case retrieval. The purpose of this research is to create a way to automatically detect system failures on machines, so that if a malfunction occurs with a CBR-based system, it will be easier to detect early, repair faster, and be more accurate. The results of the research using the CBR method are that the accuracy of the system used is 90%, in accordance with the results of testing the tools produced, and effective for managing production machine repairs. While the test error is twenty times with the highest result of 33.33% and the lowest 0% according to the level of accuracy of the sensor on the object. The purpose of this research is to provide analysis for companies to detect damage to production machines for operators and management to follow up on existing damage. Recommendations from the research are used to improve production machines for companies that need a comprehensive repair treatment from the existing system to a system that has computer-based reasoning for cost efficiency and economics of repairing machine tools.
