Abstract

Abstrak - Salah satu sistem informasi kebencanaanyang ada saat ini adalah Sahana.Sahana memilikiketerbatasan dalam integrasi dengan aplikasi pendukungkebencanaan yang dikembangkan olehpihaklain. Hal initerjadi karena tidak adanya platform standar yangmemiliki protokol yang terbuka untuk dapatdimanfaatkan oleh pengembang aplikasi atau sistem.Olehkarena itu dibutuhkan sebuah sistem informasikebencanaan yang bersifat universal dimana memilikiprotokol yang dapat dimanfaatkan oleh pengembang agaraplikasi yang dibuat dapat diintegrasikan secara langsungterhadap sistem informasi kebencanaan dengan diawalidengan pembuatan desain antar muka dari sisteminformasi tersebut.Penelitian ini membuat desain antarmuka yang bersifat universal dimana fitur-fiturnya lebihlengkap dari Sahana. Secara garis besar desain antarmuka antara Sahana dan Sistem informasi kebencanaanhampir sama tetapi pada sistem informasi kebencanaanterdapat tambahan beberapa fitur yaitu ManejemenTrackingdengan penggunaan UI Boostrap didalampembangunannya.Kata Kunci : Sistem Informasi, Bencana Alam, platform,antar muka

Abstract

Virtualization is a technology lately much discussed and considered as the proper way to cut costs in the construction of a data center. One example of the implementation of virtualization technologies is to using VMware. Another tools for virtualization are Xen and OpenVZ, but VMware is more flexible than Xen or OpenVZ because VMware can run a variety of operating systems. Although it has the advantage, virtualization technology also has a vital weakness, virtualization technologies could be analogous by putting all the eggs in a basket. This means that if the master server problem, all systems inside the virtual machine can not be used. However, it can be anticipated by provide backup facilities that run continually and automatically. VMware itself has had an application to backup/replicate virtual machines. However, that application is not free yet.This research has been design and creates a web-based software forbacking up virtual machines on VMware. So it made easier for users and admins to perform periodic backups of virtual machines. From the test results has been done, it can be seen that used disk type thin or zeroed thick make process backup faster, system can’t work well when virtual machine has snapshot, scheduling system and restoring system has worked well, physical ability data storage influence system.Keywords: Virtual machine, virtualization, Vmware, Backup, Data Center.

Abstract

The increasing number of online news provider has produced large volume of news every day. The large volume can bring drawback in consuming information efficiently because some news contain similar contents but they have different titles that may appear. This paper presents a new system for automatically generating representative news using on-line clustering. The system allows the clustering to be dynamic with the features of centroid update and new cluster creation. Text mining is implemented to extract the news contents. The representative news is obtained from the closest distance to each centroid that calculated using Euclidean distance. For experimental study, we implement our system to 460 news in Bahasa Indonesia. The experiment performed 70.9% of precision ratio. The error is mainly caused by imprecise results from keyword extraction that generates only one or two keywords for an article. The distribution of centroid’s keywords also affects the clustering results.Keywords: News Representation, On-line Clustering, Keyword Aggregation, Text Mining.
