Abstract

Pengenal emosi ialah suatu proses untuk mengidentifikasi emosi pada manusia. Di mana emosi dapat dikenali melalui kata-kata, intonasi suara, ekspresi wajah, serta bahasa tubuh. Pada penelitian ini penulis merancang sistem pengenal emosi dengan basis suara manusia menggunakan software matlab dengan ekstraksi ciri yang digunakan fast fourier transform yang merupakan proses ekstraksi ciri yang sederhana dengan mengubah sinyal dalam domain waktu diskrit menjadi domain waktu frekuensi. Pada penelitian ini berfokus pada empat kelas emosi: marah, netral, senang, serta sedih. Tahap pertama dimulai dari proses pengambilan data suara, pemotongan,  preprocessing, proses ekstraksi fast fourier transform dan dynamic time warping. Dari hasil tersebut diperoleh nilai akurasi tertinggi pada emosi sedih sebesar 100% dan nilai akurasi lainnya diperoleh rata-rata sebesar 66,67%. Kemudian dari keseluruhan nilai akurasi yang diperoleh untuk seluruh kelas emosi, rata-rata nilai akurasinya adalah 75%.

Abstract

This study presents the design and implementation of a low-cost aircraft orientation angle measurement system using the MPU6050 sensor and Arduino Uno microcontroller for educational applications in avionics. The system aims to simulate aircraft attitude angles—yaw, pitch, and roll—by integrating an inertial sensor module (MPU6050) with open-source hardware and software. The Arduino IDE was employed to acquire and process sensor data, while the Processing 3 environment was used to visualize the attitude motion in real time. The prototype was assembled and tested to evaluate its performance in detecting orientation changes across three axes. Experimental results demonstrate that the MPU6050-based system can accurately capture and display attitude variations without communication delay or signal error, providing a clear visualization of aircraft motion. The system’s simplicity, affordability, and open-source framework make it suitable for classroom demonstrations and laboratory exercises in avionics and control-system courses. Future improvements include the integration of Euler-angle computation and wireless communication to enhance mobility and data acquisition.
