The quality of the data provided is critical to the success of data warehousing initiatives. There is strong evidence that many organisations have significant data quality problems, and that these have substantial social and economic impacts. This paper describes a study which explores modeling of the dynamic parts of the data warehouse. This metamodel enables data warehouse management, design and evolution based on a high level conceptual perspective, which can be linked to the actual structural and physical aspects of the data warehouse architecture. Moreover, this metamodel is capable of modeling complex activities, their interrelationships, the relationship of activities with data sources and execution details.

Bluetooth is a new emerging technology. This technology gives significant changes for electronic devices that we are using. If we look around, a keyboard is connected to a computer. So does a printer, a mouse, a monitor and so on. This condition creates a problem of so many scattered wires installed in the offices, houses and other places. Another problem is how to inspect the damaging or boken wires. In this paper, we will have a discussion on specific applications of bluetooth such as services provided by the bluetooth technology; bluetooth method - how bluetooth devices make connections in a piconet; as well as investigation on bluetooth protocol stack. Bluetooth has succesfully built easy connection among devices from many vendor without using cables, with less power dan money. By using bluetooth, we can build small network or Piconet, consisting of several devices without cables. Abstract in Bahasa Indonesia : Bluetooth adalah suatu teknologi baru yang mulai dikenal dan digunakan. Teknologi ini memberikan perubahan yang signifikan terhadap peralatan elektronik yang kita gunakan. Jika kita melihat sekeliling kita dimana keyboard dihubungkan pada komputer. Demikian juga halnya dengan printer, mouse, monitor dan lain sebagainya. Semua peralatan itu dihubungkan dengan menggunakan kabel. Akibatnya terjadi masalah banyak kabel yang dibutuhkan di kantor, rumah atau tempat-tempat lainnya. Masalah lain yang ditemui adalah bagaimana menelusuri kabel-kabel yang terpasang jika ada suatu kesalahan atau kerusakan. Bluetooth memperbaiki penggunaan teknologi kabel yang cenderung menyulitkan ini dengan cara menghubungkan beberapa peralatan tanpa menggunakan kabel. Pada karya tulis ini, dibahas aplikasi spesifik bluetooth, antara lain servis-servis apa saja yang disediakan oleh teknologi bluetooth; cara kerja bluetooth yaitu bagaimana bluetooth device melakukan koneksi di dalam sebuah piconet serta bluetooth protocol stack. Bluetooth telah berhasil memudahkan koneksi antar beberapa alat dari berbagai vendor tanpa kabel dengan tenaga yang kecil serta biaya yang ringan. Dengan bluetooth dapat dibentuk sebuah jaringan kecil atau Piconet yang terdiri dari beberapa peralatan dan sekali lagi, tanpa memerlukan kabel. Kata kunci: Bluetooth, Bluetooth Protocol Stack, Piconet, Komunikasi data, Nirkabel.

SINERGI ISO 9001:2000 - CMMI PADA INDUSTRI PENGEMBANG PERANGKAT LUNAK Santoso, Leo Willyanto; Yulia, Yulia

All sectors of society including softwere industry, have a big concern about quality, both of product quality and service quality. The need to manage risk, has a strong relation with quality and increases system complexity. Standarization in determining quality, ISO is a must for all software developer. If we study further, ISO 9001:2000 still has some weakness especially for implementation in software product. This paper presents a comparative analysis of quality approaches to risk management. This paper also provide a general overview of all the risks aspects treated in ISO 9001:2000 standards and CMMI model version 1.1. In this research, we obtain a strategy to implement ISO 9001:2000 and CMMI together when we make a planing to increase software process. Besides it produces analysis how to change position from ISO 9001:2000 to CMMI. In the implementation on software industry PT 'X', obtain get various benefits that has never been obtained before. Abstract in Bahasa Indonesia : Semua hal dalam hidup ini selalu memperhatikan masalah kualitas, baik itu berupa kualitas produk ataupun kualitas layanan. Pada industri perangkat lunak, hal ini tidak dibedakan, kebutuhan untuk menghasilkan produk yang berkualitas akan meningkatkan kekompleksan dari sebuah sistem. Standarisasi dalam penentuan kualitas, ISO sudah menjadi keharusan bagi para pengembang perangkat lunak. Apabila diteliti lebih lanjut, ISO 9001:2000 masih mempunyai banyak kekurangan, khususnya untuk diaplikasikan dalam produk perangkat lunak.Pada penelitian ini, akan dibahas analisis perbandingan dengan melakukan pendekatan kualitas untuk meningkatkan proses perangkat lunak dengan melakukan mapping antara ISO 9001:2000 dengan CMMI. Hal-hal yang dibahas berupa aspek-aspek dari standard ISO dan CMMI versi 1.1. Pada penelitian ini, dapat diperoleh strategi untuk menerapkan ISO 9001:2000 dan CMMI secara sinergi ketika merencanakan untuk melakukan peningkatan proses perangkat lunak. Selain itu, dihasilkan juga analisis bagaimana untuk beralih dari ISO 9001:2000 ke CMMI. Dalam penerapannya pada industri perangkat lunak, PT 'X', diperoleh berbagai keuntungan yang sebelumnya tidak didapatkan. Kata kunci: ISO, ISO 9001:2000, capability maturity model integrated.

The existing of database processing is needed by many institutions and companies. Database is not only to get information faster, it is also enlarging their service to customer. For companies, this advantage can increase competency. Because of this reason, many companies using manual processing turn to database. As mentioned above, database reverse engineering process has became a necessity for database developers to understand the structure of any databases. Commonly, this structure is modeled in some notations of Entity Relationships Diagram (ERD). The graphical visualization of database structure in an ERD can use many notations, so it is easy to understand. One of the approaches, which are easy to understand, is Object Role Modeling (ORM) diagram. By reverse engineering the mapping process to relation schema of a database, ERD generation from a data definition language script of Oracle can be done. For more flexibility, this application is constructed web based with Servlets technology that is propertied by JavaTM 2 SDK. Abstract in Bahasa Indonesia : Kehadiran pemrosesan basis data diperlukan oleh berbagai institusi dan perusahaan. Basis data tidak hanya mempercepat pemerolehan informasi, tetapi juga dapat meningkatkan pelayanan kepada pelanggan. Bagi perusahaan, keuntungan seperti ini dapat meningkatkan daya saingnya terhadap perusahaan lain. Hal ini pulalah yang mendorong banyak perusahaan yang menggunakan pemrosesan manual mulai beralih memanfaatkan basis data. Sejalan dengan hal di atas, proses reverse engineering terhadap suatu basis data menjadi suatu kebutuhan bagi perancang basis data untuk mengetahui struktur dari sebuah basis data. Struktur tersebut biasanya dimodelkan dalam bentuk Entity Relationships Diagram (ERD). Penggambaran struktur basis data dalam sebuah ERD dapat menggunakan berbagai notasi agar menjadi lebih mudah dimengerti. Salah satu notasi yang pendekatannya mudah dipahami adalah notasi Object Role Modeling (ORM) diagram. Dengan melakukan pembalikan terhadap proses pemetaan ke skema relasi dari suatu basis data maka pembangkitan ERD dari suatu skrip pembuatan basis data Oracle dapat dilakukan. Agar lebih fleksibel, maka aplikasi yang dibangun berupa aplikasi berbasis web dengan menggunakan teknologi Servlets yang dimiliki oleh JavaTM 2 SDK. Kata kunci: Basis data, Model data konseptual, ERD, Oracle, dan Servlets.

PT. X is a company engaged in the field of iron and steel construction, located in Surabaya. Not easy for a large company with business processes that are also wide enough to carry out all processes in the company by way of the manual. This is because in the era of globalization, companies must be able to address the issues and changes that occur quickly and on target. Therefore, companies urgently need an integrated application. However, the factor that must be considered not only focuses on the acquisition of application systems needed by the company alone. But companies also need to focus on maintaining the quality of the application system. Because the application system useful to support and enhance the company's management in order to improve company performance and effectiveness in delivering services to the public. Therefore, the researcher wants to conduct the audit planning of application system for PT. X with analysis on the condition of IT at PT. X to determine the COBIT domains that need to be audited.
