Abstract

Attendance is an important part of collecting attendance data at an event. The data serves as a tool for evaluation, accountability, and event development. SMK Muhammadiyah 3 Dolopo, a vocational high school in Madiun Regency, East Java, is one of the educational institutions that requires a good attendance system. The school aims to excel in the field of technology and information. To achieve this goal, improving the quality of learning and service to students, including in terms of absenteeism, is needed. Currently, SMK Muhammadiyah 3 Dolopo still uses a manual attendance system which has several disadvantages, such as time-consuming, error-prone, easy to fake, difficult to archive, and less flexible. The use of attendance system can be done quickly and accurately, anywhere and anytime. The use of the Attendance Information System is an effective solution in monitoring and managing student attendance accurately and efficiently. Research shows that this system helps maximize learning time by ensuring timely student attendance. The results showed that the adoption of this technology has the potential to improve the overall quality and effectiveness of learning

Abstract

In an effort to enhance the efficiency and accuracy of dam monitoring, there is a need for more advanced systems compared to the manual methods still widely used. This study aims to design and develop a prototype system for monitoring water levels and controlling dam gates that can be operated automatically and in real-time. The methods used include ultrasonic sensors and water level float switches connected to an ESP-8266 microcontroller, as well as DC motors and relays to operate the dam gates. The data collected by the sensors is transmitted via the internet for remote monitoring. The results of the study show that the developed system can monitor water levels with 96% accuracy and 4% error, and provides a quick response to changes in water conditions. This system can also send real-time notifications through a web application, helping to reduce human workload and increase community preparedness around the dam area for potential flooding.
