Sistem Pendukung Keputusan (Decisin Support System)

Sistem pendukung keputusan (Inggris: decision support systems disingkat DSS) adalah bagian dari sistem informasi berbasis komputer (termasuk sistem berbasis pengetahuan (manajemen pengetahuan)) yang dipakai untuk mendukung pengambilan keputusan dalam suatu organisasi atau Perusahaan.DSS dapat juga dikatakan sebagai sistem komputer yang mengolah data menjadi informasi untuk mengambil keputusan dari masalah semi-terstruktur yang spesifik

Implementasi Web Access Monitoring Pada Proxy Squid Menggunakan Aplikasi Open Source

Jaringan komputer adalah salah satu elemen penting dalam operasi organisasi saat ini, penggunaan jaringan komputer semakin cepat tanpa jaringan yang baik manajemen, dapat mengarah pada penyalahgunaan akses dan gangguan pada operasi yang bergantung padanya. Pada sistem monitoring jaringan untuk mengawasi pengguna sangat diperlukan karenapenggunaan Proxy server dan aplikasi open source monitoring yang dapat memberikan informasi tentang kondisi dan penggunaan sumber daya server dilakukan. Mekanisme ini dapat membantu administrator jaringan dalam memantau kinerja server proxy serta mengelola dan membatasi akses oleh klien

Perancangan Dan Implementasi Mail Server Pada CV. Sanjaya Anugerah Sejahtera (Isp Jogjaringan) Berbasis Open Source

The use of email or electronic mail service is a new alternative media as one of the supporting medium of any communication activity between co-workers in the company or merely exchanging information in their daily lives to make a work activity more quickly and efficiently.The design and implementation of the mail server on the CV. Sanjaya Anugerah Sejahtera (ISP Jogjaringan) based on open source systems to support the company\u27s work and provide a new solution to communicate between kariyawan Jogjaringan to use the services on the system mail server, mail server with the system is expected to memberbaiki system work and be able to compile systematically from each division of the company.Making the system\u27s mail server using Ubuntu 10:04 64 bit server as a server operating system and Zimbra Open Source Edition Colaboration Suite as a Mail Transfer Agent. The use of open source-based system has to meet the needs of companies where the Zimbra mail server with fiture reminder service work, note any work activities, live chat services, social media, and with the ease of data sharing is to meet the needs of the working system Jogjaringan. In making diawalai mail server system with manufacturing systems with ubuntu 10.04 server 64 bit later to give naming server system supporting the necessary elements such as Domain Name System bind9 which serves as a system that provides the addressing on the server system, after the end of the installation process zimbra mail transfer agent, so that the system can mail servers running optimally is better in the server there is only one server sitem only

Analisis Keamanan Jaringan Wireless Yang Menggunakan Captive Portal (Studi Kasus : Warnet Fortran)

Nowadays the utilization of wireless-based technology has been developed, whether it\u27s for the USAge of education or for benefit of commercial needs. FORTRAN internet cafe is one of internet shops utilizing this technology. However behind the popularity of this technology there some fragility that needs to be fixed. The fragility of the technology is that it\u27s susceptible of assaults from attackers, it can be caused by the overly opened communication. Plated protection is needed in order to minimize the possibility of assaults.FORTRAN internet cafe has been attempted to minimize the weakness of the technology by using capital portal (Open System Authentication). Authentication of this method is happening when the users accessing the internet for the first time. However, this method can\u27t guarantee that the wireless network is safe from the attackers\u27 assaults. Therefore it is necessary to do some trials to know and find the chances of the safety for this technology.The trials that are done are MAC Address Spoofing and Man in the Middle Attack, where the MAC Address Spoofing is the one that\u27s successful. This shown that there is still possibility of safety for the wireless system at FORTRAN Internet Café, which is using MAC Address Spoofing. It is needed an added system to handle the existence of safety possibility.
