The laboratory is a place for scientific research and testing that requires an efficient and accurate tool lending system to ensure the availability of equipment. Conventional systems that are still based on manual recording have various weaknesses, such as being prone to errors, difficulty in tracking loan status, and lack of transparency. Based on the results of the questionnaire survey, it was found that the JGU Electronics and Robotics Lab still uses paper forms in the process of borrowing laboratory equipment. To overcome these problems, this study developed an RFID-based tool lending system that is integrated with the web to improve efficiency and accuracy. This system utilizes an RFID Reader (Mifare RC522 RFID Module) and RFID Tag as input, with data processing carried out using the NodeMCU ESP8266. The processed data is sent to the server and displayed via the website as output. In addition, the system is also equipped with a buzzer as an indicator of the success of the loan. The research methods include field surveys, literature studies, system requirements analysis, and performance testing based on Quality of Service (QoS) parameters. The test results show that the RFID Reader is able to read RFID Tags within a distance of 1-4 cm with an average delay time of 1.96 seconds and a successful response. The system also successfully sent data to the server via HTTP request with a response code of 200. QoS testing based on the TIPHON standard showed an average throughput value of 26.75 Kbps, a delay of 72.503 ms, a jitter of 72.629 ms, and a packet loss of 0.57%. This study proves that an RFID-based system can improve efficiency and accuracy in borrowing laboratory equipment. However, there are still challenges in optimizing QoS. Therefore, further research is needed to improve system performance, especially in terms of data transmission speed and integration with a broader laboratory management system.
