ANALISIS MANIPULASI SUARA YANG TELAH DI EDIT DENGAN APLIKASI SMARTPHONE MENGGUNAKAN TEKNIK AUDIO FORENSIK SEBAGAI BARANG BUKTI DIGITAL
Get PDFAudio adalah salah satu barang bukti digital yang bisa mengungkap suatu kasus yang telah terjadi akan tetapi barang bukti audio juga bisa di manipulasi dan dirubah untuk menyembunyikan informasi. Teknologi memudahkan manipulasi audio dengan aplikasi yang ada pada Smartphone secara mudah dan gratis. Audio forensik adalah salah satu teknik untuk dapat mengetahui apakah barang bukti audio tersebut apakah asli atau rekayasa, menggunakan parameter pitch, formant dan spectogram. Penelitian ini akan dilakukan meneliti kemiripan suara asli dengan suara yang di manipulasi dengan aplikasi di Smartphone dengan filter voice changer. Hasil penelitian ini akan dihasilkan analisis dilakukan untuk menemukan tingkat kemiripan/identik dengan beberapa fitur yang ada pada voice changer yang ada yang dapat disimpulkan persamaan antara suara asli dengan suara yang telah di manipulasi.
Analisis Statistik Manipulasi Pitch Suara Menggunakan Audio Forensik Untuk Bukti Digital
Get PDFRekaman suara adalah salah satu barang bukti digital yang bisa ditemukan dalam suatu kasus pidana maupun perdata, misalnya berupa rekaman perbincangan antara pelaku pidana. Barang bukti berupa rekaman suara atau audio sangat mudah dimanipulasi untuk menyembunyikan identitas dari rekaman suara tersebut. Pada era milenial ini sangat mudah mendapatkan alat atau perangkat lunak untuk manipulasi data terutama pada kasus ini adalah manipulasi rekaman suara. Aplikasi manipulasi rekaman suara pada dasarnya adalah merubah sinyal digital atau analog. Studi kasus pada penelitian ini adalah manipulasi rekaman suara menggunakan aplikasi Voice Changer yang ada pada smartphone Android dan dianalisis menggunakan statistik pitch. Penggunaan aplikasi Praat dapat diketahui nilai pitch maksimum, minimum, nilai tengah, rata-rata dan nilai deviasi standar sebagai parameter untuk mengetahui bahwa suara yang telah dimanipulasi tersebut identik dengan rekaman suara asli. Hasil yang didapatkan dalam penelitian dengan kasus manipulasi rekaman suara yang berisi 20 kata yang telah dimanipulasi adalah tidak identik dengan rekaman suara asli

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Learning Application of Daily Prayer for Deaf Children SD-LB Yayasan Rehabilitasi Tuna Rungu Wicara
Get PDFSekolah Luar Biasa Yayasan Rehabilitasi Tuna Rungu Wicara (SLB YRTRW) is a school for children in need especially deaf mute that is still experiencing obstacles in learning. Learning session still need additional time, whereas with only one PAI (Pendidikan Agama Islam) teacher and teaching elementary 1st grade until 3rd grade high school so it makes it less intensive in the learning hours. According to PAI teacher in SLB, many of foster parent are not able to give extra lessons at home. This research goals to make learning application that can help learning benedictions after hours of learning in school and may be more effective. This application will be operate on smartphone Android device which has been growing rapidly and widespread in the society of this modern era. This research was conducted on SLB YRTRW basis curriculum elementary school as whole. Based on the result of interviews and observations accompanied by PAI teacher, this application includes deaf student ability and simulate teaching method from PAI teacher to digital level. This application will be created using Construct 2 software. This application simulate an existing teaching methods with an extra exercises of composing benediction verse consecutively and this application will add additional features namely Mini Game that aims to relieve the boredom with basic a learning method do. Testing is done by way of delivering the application on foster parent and try the application at home. Based on the results of a questionnaire on the content by PAI teacher and some foster parent can be concluded that the application is quite easy to understand and can be a medium of learning in their home
