Abstract

Sapi merupakan salah satu jenis hewan ternak yang populer di Indonesia. Mereka biasanya digunakan sebagai sumber protein, seperti susu dan daging, namun beberapa petani juga menggunakannya untuk produksi bulu dan kulit. Jumlah ternak meningkat secara signifikan setiap tahunnya. Untuk memperoleh ternak yang berkualitas, pengembangan ternak harus memperhatikan peraturan perundang-undangan, nutrisi yang tepat, dan memperhatikan kesehatan ternak. Salah satu tantangan dalam menjaga kualitas ternak adalah adanya penyakit yang menyerang ternak. Kurangnya pengetahuan peternak mengenai penyakit ternak menjadi kendala bagi mereka. Pada penelitian ini dikembangkan sistem pakar dengan metode Dempster-Shafer untuk mendiagnosis penyakit pada sapi di peternakan Aek Gareder. Tujuan penelitian ini adalah menerapkan metode Dempster-Shafer, membangun sistem pakar yang memudahkan diagnosis penyakit sapi bagi peternak, dan mengevaluasi validitas dan efektivitas sistem pakar. Hasil penelitian menunjukkan tingkat akurasi diagnosis sistem pakar mencapai 95%. Dengan hadirnya sistem pakar ini diharapkan dapat meningkatkan pengetahuan peternak, memudahkan diagnosis penyakit ternak, dan memberikan kontribusi positif terhadap pemeliharaan ternak secara keseluruhan.

Abstract

Music has been an inseparable part of human life since ancient times. One form of music that is often studied is monophonic music, which consists of a single note played at a time. In the digital era, melody transcription has become an important aspect of music processing, allowing sound to be converted into musical notation. This study focuses on melody transcription from monophonic sound recordings using the Fast Fourier Transform (FFT) method. The research aims to analyze the accuracy of FFT in extracting frequency components from monophonic signals and converting them into musical notation. The research methodology involves collecting monophonic sound recordings from piano and guitar, preprocessing the audio to remove noise and normalize volume, applying FFT to extract frequency features, and mapping these frequencies into musical notation. The evaluation process is conducted using Dynamic Time Warping (DTW) and a confusion matrix to measure accuracy, precision, recall, and F1-score. The results show that the FFT-based transcription system achieves an accuracy rate of 99.24% for piano and 98.86% for guitar. The study also highlights the impact of noise and audio quality on transcription accuracy, as well as the limitations of FFT in detecting closely spaced frequencies. Despite these limitations, FFT proves to be an efficient method for melody transcription in simple monophonic music. Future research could explore hybrid approaches combining FFT with other pitch detection algorithms to improve transcription accuracy.
