Abstract

AC (Air Conditioner) is an air conditioning system that is used anywhere, one of them on the train. Air conditioning is also a major factor in the comfort level of train passengers. However, train air conditioning currently can only be controlled manually from the driver's cabin so that the number of passengers does not affect the air conditioning temperature. What's more, the air conditioner absorbs 30% of the total power in the train. Therefore, this research was compiled with the aim of being able to calculate the number of passengers through the concept of people counting using the You Only Look Once (YOLO) method for the train's temperature control system. This research was built using 1 object class, namely person and the YOLOv5 algorithm, where this method is an object detection method with a high degree of accuracy. This research was designed using the Python programming language with the Google Colaboratory platform and MQTT for the data storage protocol for passenger detection results. The dataset used is passengers in the train as many as 1300 images. The training and validation results model obtained a 99.63% mAP, 95% precision, 100% recall, 97.5% F1 score, and 79.96% average IoU. Then, the model was tested and obtained 99.35% mAP, 95% precision, 99% recall, and 97% F1 score. This research resulted in a fairly good system performance in detecting and counting passengers on trains.

Abstract

PT. Neora Infrastructure Indonesia is an industrial company engaged in telecommunications and/or telephone transmission network construction services, collaborating with Fiberstar. This necessitates the company to constantly require competent human resources. However, the company must compete with others to acquire competent personnel. Nevertheless, the employee selection process at PT. Neora Infrastructure Indonesia is still manual and takes 2 - 4 weeks, making it difficult for the company to compete in acquiring competent personnel. Therefore, it was decided to develop a decision support system to assist the company in efficiently and effectively selecting employees. The decision support system for employee selection uses the ROC and CPI methods. The ROC method is used to determine the criteria weight values, while the CPI method is used for ranking all alternatives. Quantitative method is the research method used, and several types of UML diagrams including Activity diagram, Class diagram, and Use case diagram are utilized for system design. The RAD method is employed for system development. With the establishment of the decision support system for employee selection using the ROC and CPI methods, it is expected that the company can compete with others in obtaining competent human resources and that the employee selection process becomes efficient and effective
