Abstract

Abstrak— Gitar akustik merupakan salah satu alat musik terpopuler di dunia. Suara yang dihasilkan gitar memiliki karakteristik suara nya masing-masing. Salah satu faktor yang memengaruhi karakteristik suara gitar adalah jenis senar gitar. Gitar terbagi menjadi 2 jenis berdasarkan jenis material senar nya yaitu senar yang terbuat dari baja dan senar yang terbuat dari nylon. Senar baja cenderung menghasilkan suara yang lebih nyaring dan volume suara yang lebih besar dibandingkan dengan senar nylon yang cenderung menghasilkan suara yang mellow. Namun tidak semua orang dapat membedakan suara gitar atau mengetahui berdasarkan senar yang digunakan hanya dengan mendengarkan suaranya saja. Sistem deteksi bahan gitar ini bertujuan untuk membedakan jenis senar pada suatu gitar. Total kelas di sistem ini terbagi menjadi dua kelas, kelas senar baja dan kelas senar nylon. Hasil dari sistem ini berupa GUI yang memunculkan spektogram dan hasil deteksi. Sinyal suara akan melalui proses ekstraksi ciri akustik menggunakan metode MFCC dengan parameter delta-delta window length terbaik bernilai 5. Hasil dari proses tersebut kemudian akan diklasifikasikan dengan metode support vector machine (SVM) dengan fungsi kernel RBF sebagai fungsi terbaik dengan akurasi 95%. Gitar senar baja cenderung menghasilkan frekuensi maksimum yang lebih besar dibandingkan dengan senar nylon. Kata kunci— Gitar Akustik, Senar Baja, Senar Nylon, MelFrequency Cepstral Coefficients (MFCC), Support vector machine (SVM).

Abstract

Video piracy is the act of obtaining, copying, and selling or distributing videos that already had the copyright without the consent of the copyright owner. Watermarking is a process which embeds an additional information in the host video signal so that the embedded watermark cannot be seen and difficult to be erased or altered. Video watermarking in this journal used a mp4 format video and two different watermark images. Host video frames are divided into two equal lots, some of the frames are embedded by watermark image 1, and the others are embedded by watermark images 2. The methods used are Dual-Tree Complex Wavelet Transform (DTCWT) and Singular Value Decomposition (SVD). The two watermarks are embedded and extracted in each subband at a depth level 1 to level 4 DTCWT - SVD with the aim of seeking the best subband and the best level for embedding and extracting. In the extraction testing, watermarked video is given several attacks before extraction process. Based on the MOS and PSNR value the DTCWT-SVD level for embedding process is level 4, and based on the MOS and MSE value, the best extraction images are produced from the level 3. The best subband for embedding watermark are the subbands with three parts such as {1,5}{1,1}{1,2} and {1,5}{1,2}{1,2}.

Abstract

Height and weight are parameters to identify a person, especially for a forensic. To identify height and weight is usually done manually. In addition to manually using height measuring devices and scales, you can also use information related to the foot length. There is a relationship between height and foot length can be expressed in the correlation coefficient (r) as same as for weight. Therefore, in this study, a system for measuring human height and weight based on images of the footprint is implemented on Android. The methods used in this study are Gabor Wavelet and k-Nearest Neighbor (k-NN). The simulation results generate the best accuracy of 75%. The system can also used to categorize the ideal body level according to the Body Mass Index (BMI). The system is able to process images with an average computation time of 8.92 seconds.
