Sistem Monitoring Stabilitas Bow Hand Atlet Dalam Latihan Panahan Menggunakan Accelerometer

Abstract

Stability of motion takes a crucial role in determining archery shot quality, requiring coaches and athletes to have an objective and real-time monitoring method to improve training performance. This system was developed using an MPU-6050 accelerometer mounted on the bow riser to measure hand-movement coordinates during the drawing phase. Sensor data are transmitted via the MQTT protocol and visualized on a dashboard in the form of line graphs. The study involved field trials in collaboration with archers from Universitas Sumatera Utara (USU), specifically in the standard bow and barebow divisions. The system is capable of recording time, accelerometer reading statistics, shot scores, and stability levels. Experimental results indicate that the variable most closely correlated with shot score is time, with a Pearson Correlation Coefficient of 0.2. Additionally, stability was found to be inversely related to amplitude, with a strong negative Pearson Correlation Coefficient of −0.95.
