Implementation of a Microcontroller-Based Cup Availability Monitoring System for the Automated Milk Pasteurization Production Process at MSME Luru Barokah. This research aims to design, build, and implement a microcontroller-based monitoring system to automate this process. The methodology includes observation, interviews, literature review, and documentation, with system development following the Research and Development (R&D) model encompassing analysis, design, development, evaluation, and implementation phases. The developed prototype utilizes an Arduino Uno R3 and an HC-SR04 ultrasonic sensor to continuously detect cup distance, using a calibrated threshold of 16 cm. The system also features a buzzer for audible alerts and red and green LEDs as visual indicators of cup availability status. Implementation results demonstrate 100% detection accuracy and a rapid response time of under one second, effectively assisting operators by eliminating the need for manual checks. This implementation is expected to enhance operational efficiency, minimize the risk of human error, and support the smooth operation and sustainability of milk pasteurization production at UMKM Luru Barokah
