Abstract

Recently, the main focus in research and development are pointing to multimedia data, including audio. The method used for indexing and retrieval of multimedia data is known as MIRS  (Multimedia Indexing and Retrieval System). MIRS differs from traditional database management system since multimedia data has different characteristics compared to alphanumeric data. In this research a method for indexing and retrieval of audio file is developed and evaluated. The number of samples of the data used in this research are varied, but the sampling rate and the numer of bits per sample are the same. An audio file is represented by a number of features extracted from the file and stored in the system’s database. The features used for this research are average enegy, zero crossing rate and silence ratio. The three features are used for matching between query audio file and audio file in the database either individually or simultaneously. The experimental results show that the succes rate of this system to find audio files depends on the feature used and the threshold used for measuring the similarity between query audio and files in the database.  By using Euclidean Distance, the average energy gives 90% succes rate, the zero crossing rate gives 77% succes rate, the silence ratio gives 90% succes rate and the combined feature gives 90% succes rate. This succes rate percentage showed that the features used to recognize similarity between query audio file and database audio file is appropriate.   Keyword :  MIRS, average energy, zero crossing rate, silence ratio

Abstract

Have been conducted a research of web based library information system development on-line at Darmajaya. At this time, Darmajaya`s Library has 4551 eks with 1993 titles, 86 eks Journal with 44 titles, 660 eks of final assignments,  186 eks of Skripsi and 443 eks of KP report, and this will be continued to increase along with the program of book levying coming from student. Donation and also form institution. At this time data of book`s catalogue at Darmajaya`s Library still using Microsoft Excel Application, and final assignment report data, skripsi, and KP report recorded at main book. This system, will have major influence with Darmajaya Library Services to members. With this Research Result can facilitate all library member to access the book information, Journal, KP report, Skripsi / Final Assigment, and GBPP through Internet. This Library Information System can improve Darmajaya Library services and represent one of place for the publication of scientific innovation / creation for all lecturer or student.

Abstract

Pada penelitian ini akan dikembangkan suatu perangkat lunak bantu pengontrol dan monitor suatu keamanan ruangan berbasis Short Message Service (SMS) dan mempergunakan internet protocol camera (IPCam), serta berintegrasi dengan komponen-komponen perangkat keras seperti handphone dan komputer, yang menghasilkan suatu fungsionalitas tertentu untuk membantu sistem pengamanan ruangan. SMS digunakan sebagai antarmuka antara sistem dengan pengguna. Pengguna dapat mengetahui status keamanan ruangan yang dilaporkan oleh sistem melalui SMS. Pengguna pun dapat mengendalikan peralatan elektronik yang terhubung ke sistem dengan cara mengirim SMS yang berisi perintah ke sistem. Perangkat lunak bantu pengontrol keamanan ruangan berbasis SMS, bisa dikonfigurasi melalui panel khusus atau melalui pengiriman pesan singkat /SMS oleh pengguna tertentu. Pesan yang dikirim akan mengacu pada sintaks yang telah didefinisikan, dimana setiap sintaks akan memiliki semantik yang menggambarkan jenis layanan tertentu. Pada saat yang bersamaan akan mengirim infromasi ke pengguna berupa pesan singkat SMS melalui Handphone gateway, Model pembangunan perangkat lunak menggunakan waterfall model prototype dengan metode berorientasi aliran data. Penghubung antara komputer dan rangkaian elektronik yang menjadi pengendali menggunakan mikrokontroller pada parallel port. Perangkat lunak yang digunakan untuk sistem ini dikembangkan dengan Java 2 Platform Standard Edition (J2SE) 1.5.0 dan menggunakan MySQL sebagai sistem database dan penerapan Internet Protocol Camera sebagai media untuk meonitoring berbasis jaringan baik intranet maupun internet   Kata Kunci : short message service (SMS), Internet Protocol Camera (IPCam), sistem pengendal controlling, sistem pemantauan  monitoring, java,  internet daniIntranet
