Abstract

Penerapan Dominance-based Rough Set Approach (DRSA) untuk menentukan peringkat kualitas sejumlah aplikasi berbasis objek telah dipelajari. DRSA diterapkan untuk memformulasikan satu set klasifikasi dimana kualitas software aplikasi digolongkan. Klasifikasi dibentuk berdasarkan hasil pengukuran Metrics of Object Oriented Design (MOOD) terhadap properti software berbasis Java. Pemanfaatan DRSA merupakan metode alternatif untuk menginterpretasikan nilai-nilai metrics dan menentukan sebuah nilai kuantitatif yang merepresentasikan kualitasnya relatif terhadap software yang lain. Studi eksperimental menunjukkan bahwa akurasi hasil DRSA bergantung pada jumlah sample aplikasi yang dijadikan referensi dalam menurunkan satu set definisi aturan untuk mengklasifikasikan properti software. Sample aplikasi dalam eksperimen diambil dari library Java yang telah teruji modularity, usability dan maintainability-nya. Secara umum, hasil eksperimen menyimpulkan bahwa DRSA dapat diterapkan untuk menentukan peringkat kualitas relatif dari sejumlah aplikasi dalam populasi sample. Application of Dominance-based Rough Set Approach (DRSA) to rank the quality of a number of object-based applications have been studied. DRSA applied to formulate a set of software quality classification in which the application is classified. Classification established by the results of measurements Metrics of Object Oriented Design (MOOD) against the property of Java-based software. Utilization of DRSA is an alternative method for interpreting the values of metrics and determine a quantitative value that represents the quality relative to other software. Experimental studies indicate that the accuracy of the DRSA depends on the number of sample applications that are used as reference in the definition set down one rule for classifying software properties. Sample applications in the experiment was taken from a proven library Java modularity, usability and maintainability of his. In general, the experimental results concluded that the DRSA can be applied to rank the relative quality of a number of applications in the sample population.

Abstract

Kajian terhadap beberapa pendekatan virtualisasi telah dilakukan dan dilaporkan dalam paper ini. Pendekatan virtualisasi yang dikaji adalah full virtualization, hardware-assisted virtualization, paravirtualization, dan operating system-level virtualization. Evaluasi dilakukan melalui pengukuran kinerja masing-masing pendekatan dengan beban kerja tertentu saat dijalankan menggunakan virtualisasi dan saat virtualisasi tidak digunakan. Hasil eksperimen menunjukkan bahwa operating system-level virtualization lebih efisien dalam hal penggunaan sumber daya komputer dibanding pendekatan lainnya. Hasil evaluasi menunjukkan bahwa pendekatan virtualisasi seharusnya ikut menjadi pertimbangan dalam memilih solusi virtualisasi. Study of some of the virtualization approach has been carried out and reported in this paper. Virtualization approaches that were examined are full virtualization, hardware-assisted virtualization, paravirtualization, and operating system-level virtualization. Evaluation is done by measuring the performance of each approach with a particular work load when run using virtualization and virtualization when not in use. The experimental results show that the operating system-level virtualization is more efficient in the use of computer resources than other approaches. Evaluation results show that the virtualization approach should help to be a consideration in choosing a virtualization solution.

Abstract

Abstract Congestion is one of the severe problems that occurs in big cities like Jakarta, the center of the Indonesian government. One alternative solution to solve this problem is with a Traffic Information System which is easily accessible by the public. Twitter as a social media can be used as one of information source to develop the Traffic Information System. The most common problem in the processing of information on Twitter, especially in Indonesia, is the use of abbreviations and typographical error (typo). We propose an application of Web Place Name Dictionary in addressing abbreviations and typos in the name of the location contained on Twitter to develop a Traffic Information System. Three cases in find coordinate point in the street that derived from location name in Twitter can be handled through the proposed system. This system produces 90% accuration rate on 100 data set that obtained via @TMCPoldaMetro. This study only focus on the implementation of Web Place Name Dictionary method so we do not compare our system with the other methods.
