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

This research investigates the classification of durian leaf images using Convolutional Neural Network (CNN) algorithms, specifically focusing on the architectures AlexNet, InceptionNetV3, and MobileNet. The study begins with the collection of a dataset comprising 1604 images for training, 201 images for validation, and 201 images for testing. The dataset includes five classes of durian leaves: Bawor, Duri Hitam, Malica, Montong, and Musang King, chosen for their varied characteristics such as taste, texture, and aroma. Data preprocessing involved several steps to ensure the images were suitable for model training. These steps included data augmentation to increase variability, pixel normalization to standardize the images, and resizing to 150x150 pixels to match the input requirements of the CNN models. After preprocessing, the CNN models were implemented and trained using deep learning frameworks such as TensorFlow and PyTorch. Model performance was evaluated using a Confusion Matrix, which provided detailed insights into classification accuracy, precision, sensitivity, specificity, and F-score. The results indicated that InceptionNetV3 and AlexNet achieved near-perfect classification accuracy, with no misclassifications, demonstrating their robustness and precision in identifying durian leaf images. The training accuracy for both models rapidly approached 100% within the first few epochs and stabilized, while the loss values decreased sharply, indicating effective learning without overfitting. In contrast, MobileNet, while showing high accuracy and low loss during training, exhibited several misclassifications across all classes. The training accuracy of MobileNet also approached 100%, but the presence of misclassifications suggested that further tuning and improvements were necessary. Specifically, MobileNet's Confusion Matrix revealed errors in correctly identifying samples from each class, indicating potential areas for enhancement in the model's architecture or preprocessing techniques. In conclusion, InceptionNetV3 and AlexNet proved to be highly efficient and accurate architectures for classifying durian leaf images, making them suitable for practical applications. MobileNet, although performing well, requires further refinement to achieve the same level of accuracy and reliability. This study highlights the importance of selecting appropriate CNN architectures and the need for thorough preprocessing to optimize model performance in image classification tasks.

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.
