Abstract

Abstrak:Pengenalan sinyal wicara merupakan satu ranah penelitian yang menarik. Banyak sekali metodayang bisa digunakan dalam pengolahan sinyal untuk mendapatkan pengenalan sinyal wicara. Salah satumetoda yang bisa digunakan adalah analisis ceptral, untuk mendapatkan ceptral koefisien. Setiap koefisienyang dihasilkan oleh sinyal wicara memiliki pola suara yang bisa dikenali. Dalam analisis ini terdapatsederetan pemrosesan yang melibatkan hitungan rumit. Ceptral merupakan bentuk invers dari Fast ForierTransform (FFT).Selanjutnya diolah dengan metoda Linear Predictive Coding. Kemudian dilakukanautokorelasi ke dalam bentuk koefisien cepstral. Setelah itu koefisien tersebut akan disesuaikan ke dalambentuk yang bisa dikenali oleh jaringan syaraf tiruan dengan metoda back propogation. Dari hasilserangkaian proses tersebut dihasilkan 297 koefisien cepstral untuk satu pola yang akan dikenali. Hasilpengujian dengan pola 297x25x1, learning rate 0.25, momentum 0,6 menghasilkan pola yang dikenalidengan error 4% dan keberhasilan sebanyak 96 %.Kata Kunci: Wicara, Cepstral, Fast Forier Transform (FFT)Abstract:The introduction of the speech signal is an interesting research domain. There are so many methodsthat can be used in processing the signal to obtain the speech signal recognition. One method that can beused is the analysis ceptral, to get ceptral coefficient. Each coefficient generated by the speech signal has avoice pattern recognition.In this analysis from a series of processing that involves a complicated matter.Ceptral an inverse form of Fast Forier Transform (FFT).Further processed by the method of LinearPredictive Coding. Then do the autocorrelation in the form of cepstral coefficients. After that, the coefficientswill be adapted into a form that can be recognized by the neural network with back propogation method.From the results of this process produced a series of 297 cepstral coefficient for the pattern to be recognized.The test results with the pattern 297x25x1, 00:25 learning rate, momentum 0.6 produces recognizablepattern with 4% error and success as much as 96%.Keywords: Speech, Cepstral, Fast Forier Transform (FFT)

Abstract

Abstract - The rapid growth of housing in Asahan has actually caused business competition among unhealthy housing developers. Problems that often arise due to unfair competition between developers are developers trying to market their housing without taking into account the quality and legality of the housing to be built. The choice of housing can provide convenience to consumers in determining housing choices from the value of the comparison of each housing chosen by the community. The problem to be discussed in this study is how to choose the right housing using the Analytical Hierarchy Process (AHP) method. Keywords - SPK, Housing, Election

Abstract

Employee acceptance is the most important thing for a company to obtain a new competent employee. Employees are the main assets of companies that become planners and active actors of organizational activity. In some companies, the process of receiving new employees is still not done professionally. So often we find new employees coming into a company only survive in a short time only. The main reason is the recruitment error. To solve these problems required analytical techniques that can assist corporate management in making decisions to determine new employees at PT. Indah Jaya. The method used in this research is TOPSIS (Techinique for Order Preference by Similarity to Ideal Solution) method which is one of the methods in Decision Support System (SPK). Through the application of this method, researchers can compare each prospective employee based on the criteria that determine the prospective employee is considered qualified. Such as education criteria, work experience, skills / abilities, age, character and other criteria.

Abstract: The Mandiri Computer Education Course (LKP) Institute, Asahan, North Sumatra, is a training institution that provides Information Technology training packages. During this time the training carried out by tutors only featured internet or existing people's blogs without teaching them to create blogs. Then the Community Service Team (PKM) STMIK Royal Kisaran providing training to students of the LKP as an addition to the deepening of blog material that is felt necessary to be given to students LKP. Implementation is done by direct practice accompanied by presentations and discussions and using computers to provide direct understanding to students LKP. The material of activities given to participants can be used and used directly by students in creating a blog in accordance with the concepts that exist in creating a blog.            Keywords: Blogs, Computers, Institutions Educational Courses, Training, Students  Abstrak: Lembaga Kursus Pendidikan (LKP) Mandiri Komputer Kabupaten Asahan Sumatera Utara, merupakan lembaga pelatihan yang menyediakan paket-paket pelatihan Teknologi Informasi. Selama ini pelatihan yang dilaksanakan oleh tutor hanya menampilkan internet atau blog orang yang sudah ada tanpa mengajarinya dalam pembuatan blog. Maka tim Pengabdian kepada masyarakat (PKM) STMIK Royal Kisaranmemberikan pelatihan kepada siswa LKP tersebut sebagai penambahan pendalaman materi blog yang dirasakan perlu untuk diberikan kepada siswa LKP. Pelaksanaan dilakukan dengan cara praktek langsung disertai dengan presentasi dan diskusi dan menggunakan  komputer untuk memberikan pemahaman langsung kepada siswa LKP. Materi kegiatan yang diberikan kepada peserta dapat digunakan dan dimanfaatkan langsung oleh siswa dalam membuat blog sesuai dengan  konsep yang ada pada pembuatan blog. Kata kunci: Blog, Komputer, Lembaga Kursus Pendidikan, Pelatihan, Siswa
