Abstract

Penelitian mengenai perancangan sistem pengukuran detak jantung berhasil dilakukan. Pengukuran detak jantung mandiri dapat membantu dalam menjaga kesehatan. Fotopletismogram atau PPG merupakan metode yang mampu memberi kemudahan dalam pengukuran detak jantung. Sensor PPG Easy Pulse Plugin adalah salah satu sensor PPG dengan modul pengondisi sinyal. Sensor PPG dihubungkan dengan Arduino untuk membaca sinyal dan memberikan perintah pengiriman secara nirkabel ke Android smartphone melalui Bluetooth. Aplikasi pada Android akan menampilkan sinyal dan hasil pengukuran detak jantung. Hasil pengukuran akan disimpan pada penyimpanan internal Android. Perhitungan detak jantung dilakukan berdasarkan interval waktu antar puncak pada sinyal PPG. Algoritma penentuan puncak sinyal PPG asli dapat dilakukan dengan memberikan kombinasi antara threshold dan batas interval pada sinyal PPG. Threshold terbaik adalah 2,13 V dan batas interval terbaik adalah 0,45 detik. Nilai kombinasi ini memberikan error rendah, yaitu 4,26%. Nilai sensitivitas, prediktif positif sekaligus.

Abstract

Accurate monitoring of mouse behavior in the Elevated Plus Maze (EPM) is essential for anxiety-related biomedical research, yet manual observation is time-consuming, subjective, and prone to human error. This study proposes an optimized automated tracking framework that integrates YOLOv8 detection with tracking methods including an adaptive Kalman Filter and DeepSORT, and compares them with conventional trackers such as CSRT and GOTURN. System performance was evaluated using Intersection over Union (IoU), Center Location Error (CLE), and Frames Per Second (FPS), with the Weighted Scoring Method (WSM) used for overall performance comparison. Experimental results show that the proposed YOLOv8 with adaptive Kalman filtering (frame interval = 5) provides the best balance between accuracy and computational efficiency. The approach achieved an IoU of 0.89 and CLE of 2.34 while increasing processing speed from 10.44 FPS to 22.55 FPS, representing an improvement of approximately 116% compared with the baseline configuration. Despite a slight increase in failure rates, the framework maintained stable real-time tracking performance under laboratory conditions. These results demonstrate that the proposed system improves both tracking efficiency and robustness, offering a reliable automated solution for high-throughput behavioral monitoring. The framework is particularly suitable for laboratory automation environments, supporting more objective behavioral assessment and improved data integrity in preclinical biomedical research.
