The bone fracture detection using X-rays or CTscan produces accurate images but has harmful effect radiation. This paper presented the use of ultrasonic waves (US) as an alternative to substitute those two instruments. This study used femur bovine and chicken bones in conditions with and without meat. The fractures are artificially made on transverse and oblique patterns. The scanning US probe produces twodimensional (2D) B-mode images. Fracture detection is done using five variations of the Convolutional Neural Network (CNN) architectural design, i.e., CNN1-CNN5. The results showed that the CNN4 is the best design of bone contour recognition and bone fracture classification compared to the other tested designs, with 95.3% accuracy, 95% sensitivity, and 96% specificity. The comparison with the Support Vector Machine (SVM) and k-NN classification methods indicate that CNN has superior performance in accuracy, sensitivity, and specificity. Intisari-Pendeteksian patah tulang dengan X-ray atau CTscan menghasilkan gambar yang akurat tetapi memiliki efek negatif radiasi yang berbahaya. Makalah ini memaparkan penggunaan gelombang ultrasonik (US) sebagai alternatif pengganti kedua instrumen tersebut. Makalah ini menggunakan tulang femur sapi dan ayam dalam kondisi dengan dan tanpa daging, dengan patahan dibuat secara manual dengan pola patah transverse dan oblique. Pemindaian probe US menghasilkan citra B-mode dua dimensi. Pendeteksian tulang patah dilakukan menggunakan lima variasi desain arsitektur Convolutional Neural Network (CNN), yaitu CNN1-CNN5. Hasil uji coba menunjukkan bahwa desain arsitektur CNN4 memberikan hasil pengenalan kontur tulang dan klasifikasi tulang patah yang paling bagus dibandingkan desain arsitektur lain yang diuji, dengan akurasi 95,3%, sensitivitas 95%, dan specificity 96%. Hasil perbandingan dengan metode klasifikasi Support Vector Machine (SVM) dan k-Neural Network (k-NN) menunjukkan bahwa CNN memiliki unjuk kerja yang lebih unggul baik dalam hal akurasi, sensitivitas, maupun specificity. Kata Kunci-Citra ultrasonik B-mode, Convolutional Neural Network, lapisan konvolusi, tulang femur.
Cats are one of the most popular animals in the world. Many cat breeds in the world are only about 1%. Therefore, most are dominated by mixed cats or domestic cats. Nevertheless, there are so many different types of cat breeds in the world that it is sometimes difficult to identify them. Therefore, we need a system that can recognize and classify the types of cat breeds automatically. In this study, we used one of the deep learning methods that can recognize and classify an object, a Convolutional Neural Networks (CNN). The EfficientNet-B0 architecture was used as a model to extract image features automatically. The collection of nine different cat breeds containing 2700 images was used as a working dataset fed into the EfficientNet-B0 architecture. Based on the experiments, the system succeeds in classify cat breeds images, and the best model has achieved classification accuracy of 95%.
Kucing merupakan hewan yang sangat popular di dunia. Jumlah dari ras kucing di dunia hanya sekitar 1% saja, sehingga didominasi oleh ras campuran maupun kucing domestik. Namun demikian, ada begitu banyak jenis ras kucing di dunia, sehingga terkadang sulit untuk mengidentifikasinya. Oleh karena itu, dibutuhkan sistem yang dapat mengenali jenis-jenis ras kucing. Dalam penelitian ini, penulis menggunakan salah satu metode deep learning yang dapat mengenali dan mengklasifikasikan suatu objek, yaitu Neural Convolutional Network (CNN). Penulis menggunakan 9 jenis ras kucing yang berbeda berisi 2700 gambar. Dalam pengujiannya, penulis menggunakan arsitektur EfficientNet-B0. Model paling optimal dari pengujian yang dilakukan terhadap 180 gambar kucing memperoleh tingkat akurasi sebesar 95%.
