Abstract

ABSTRACT               Three-tier architecture is an innovation of client server architecture. In the three-tier architecture, there are services presentation or user interface logic is placed on the client machine. Issued on the business logic and the client code is placed in the middle level. Data services layer contains the database server. Each level in the three-tier models are on a separate computer. Three-tier model concept is a concept that divides functionality into layers, applications gain scalability, and security. Currently the system at PT. Ungaran Sari Garment has been computerized in handling the transaction flow of goods in and out. However, the application still has the disadvantage that the application can only be used by a single computer (stand alone) and standard office without any database and system well. With the advantages of three-tier architecture, then build warehouse management system using three-tier architecture to assist in arranging entry and exit of goods to the warehouse, making the system more efficient in terms of use. Results from this study is the implementation of the warehousing system with three-tier architecture using SQLyog as its database can be used to input data entry and exit of goods to the warehouse, checking periodically warehousing reports in accordance with the functionality of each admin. By using a three-tier architecture as not to burden-sharing functionality on the server side and the client, because can use any computer that has been given permission by the server and are interconnected by a network. On the client side is only installation any web browser Keywords : Warehouse management system, Website, Client server, Three-tier.

Abstract

AbstractServers are computers for computer center managers and the other. Many more client could make server have a hard woking. this situation will make the web serverperformance has decrease and making the access to the server will be difficulty because  the server was busy or time-out. another problem is a down server or server failure. that is the problem that we must be avaoided. To overcome these problems, merging severalserversinto a single unitthat can worksimultaneouslyforload balancingserveris the solution. One method that is meaningful is using load balancing or even distribution of a burden ( request ) on the web server aims to relieve a burden is borne each server. In the process load balancing any one kind of load balancer is HAProxy, HAProxy is a software load balancer to the application of tcp and http who support a need a counterweight burden.Haproxy have the ability to control traffic of each request data from clients and showing statistics from on use each web server that it can controlling. Design and implementation of haproxy as balancer reverse a proxy be able to address the problems caused by burden excessive traffic because haproxy divide the expense request that goes into server haproxy so that the use of haproxy as load balancer can overcome the problems because the distribution of the burden known to second server backend. Keyword: Network, Load Balancing, HAProxy

Abstract

ABSTRACTThe increasing number of users who have connected to each other sometimes makes a lot of obstacles on the server, such as an increase in the performance of the server process that makes the server down and a lot of running processes. To overcome these problems, merging several servers into a single unit that can work simultaneously for load balancing server is the solution. One method is to use a proper load balancing or load balancing (request) to a web server aims to ease the burden on each server. In addition to cope with the load balancing methods, to keep the server in order to remain stable, the required monitoring network load balancing. In this issue, the monitoring process can be overcome with the addition of Munin to monitor the state of the server. With the addition of munin on the network load balancing, the activity on the server is going down in the event of a server, it can be directly terdeteksi.Munin produce produce a nice graph virtually every aspect of the server (load average, memory usage, CPU usage, traffic eth0 , etc.). Munin provide some information in graphs through a web interface. Keyword : Network, Load Balancing, Monitoring, Munin

Abstract

ABSTRACTNowadays, the existence of VoIP communication is growing fast. However, communication that is common at this time has not fulfilled the needs of specific users. For particular users, the safety and fluency of the communication is the fundamental needs. This is about VoIP communication that combined between FreeSWITCH as SIP Server, ZRTP as an encryption method to securing communication, and the use of G.729A as an audio codec. To collect the data, it will use the wireshark application for observing Quality of Service during the communication such as delay, jitter, and packet loss. While cain& able application is used for sniffing the process of communication on the network. Using a process of testing using sniffing method, communication on the network which is not using encryption can be caught and read by both wireshark and cain& able application, while communication on the network which is using encryption can not be read by both application. The result of VoIP communication using ZRTP protocol as an encryption method is can not be read and decoded by wireshark and cain& able and the use of codec G.729A is more suiteable for VoIP communication. Keywords: VoIP, FreeSWITCH, G.729A, ZRTP, Encryption

Abstract

ABSTRACT       Department of Transportation, Communication and Information of Manggarai Regency, is one of the instance of Regional Government of Manggarai, NTT, which is responsible to help the Head of Region concerning transportation, communication and information affairs. The lackness of human resources which was competent in computer networking, the high cost of VSAT IP Broadband internet service and maintenance cost of network’s backbone which is wireless based, have been becoming a problem to the Department concerning their main duties. As an impact, it is necessary to the Department to change their network’s backbone to wired network based, using VLAN. VLAN can divide network into several segments with low cost implementation. The using of VLAN Trunking Protocol (VTP) will ease the network administrator in managing VLAN.            The VLAN design in this study used hierarchical model. The logical layer for data distributing was divided into two layers, core/distribution and access layer. Routing between VLANs used “router-on-a-stick using trunk” model, so that the workstations which were owned by different VLAN can communicate each other by using one router only. By using simulation method for testing the design, it was discovered that all workstations between different VLAN have been successfully connected each other and all servers were well-functioned.   Key words : VLAN, VTP,  hierarchical, router-on-a-stick using trunk
