Abstract

Music is a creative form of expression that utilizes sound arranged in specific patterns to create artistic works that are enjoyable to the listener. However, in music, excessive or continuous exposure to loud sounds can damage the hair cells in the ear, potentially leading to hearing loss or even deafness. One challenge in musical instrument craftsmanship is the variation in sound produced by different kantil artisans. These differences in sound output lead to inconsistencies in the rhythm of the angklung gamelan in Bali. This research addresses the issue by focusing on the process of synthesizing kantil sounds to achieve a more consistent output. The research begins by inputting audio files for each sound bar in format. The recorded audio data undergoes preprocessing using the Fast Fourier Transform (FFT) method, which extracts key features from the dataset, such as the fundamental frequency. Additionally, the Hilbert Transform is applied to obtain the optimal sound each blade, which will later be used in the Frequency Modulation process. Once preprocessing is completed on the dataset for each blade, the fundamental frequency and signal are acquired. To evaluate the accuracy of the synthesis, the Root Mean Square Error (RMSE) is calculated to compare the original signal with the synthesized signal. This step helps determine the degree of difference between the two signals. Ultimately, the result is a synthesized kantil sound that closely resembles the original, helping to standardize sound output among different craftsmen and ensuring consistency in musical performances

Abstract

Pada suatu perusahaan pasti memiliki ruang rapat yang digunakan untuk berbagai kepentingan. Jika suatu perusahaan memiliki divisi testing software atau quality assurance, pasti dibutuhkan perangkat yang digunakan dalam melakukan testing. Dalam melakukan peminjaman ruang dan perangkat, biasanya karyawan melakukan peminjaman melalui admin atau karyawan yang bertanggung jawab. Di PT. Kode Aplikasi Indonesia, peminjaman ruang maupun perangkat masih dilakukan secara manual, dengan aplikasi peminjaman ruang dan perangkat berbasis website, proses peminjaman dapat dilakukan kapan saja, dimana saja, dan melalui perangkat apa saja. Melalui aplikasi ini, karyawan dapat langsung melihat dan memilih ruangan yang diinginkan berserta tanggal kebutuhan. Selain itu, Admin juga dapat mengelola peminjaman baik ruang maupun perangkat dengan lebih baik. Dengan aplikasi ini, proses peminjaman dapat lebih menjadi efektif.
