Abstract

Special Region of Yogyakarta a top of major tourist after Bali Province. Yogyakarta have many special of tourism place. For support the tourism place, then many of hotel industrial to promote and give many information about our hotel. For that, have one mobile information system about hotel location in Special Region of Yogyakarta can to display into the map. Mobile operating system like Android currently very popular among mobile phone users, because almost everyone already have.The process of making this hotel Mapping System requires primary data and secondary data obtained from Government Tourism Office Special Region of Yogyakarta. This hotel mapping system uses location-based service that combines the process of mobile services with the geographical position of its. The mobile information system making use PHP, HTML, CSS, Java programming language, MySQL database, Apache web server, and Sublime Text Editor and Android Studio IDE. This system use UML modeling system, UML modeling use is Use Case Diagram, Activity Diagram, Sequence Diagram, and Class Diagram. Results of this research is this system can helping user to give very detailed information about hotel location, ease to search hotel location and choose hotel categories, make it easy for users to open website and call hotel by one button, and ease to input coordinate location of hotel by operator.

Abstract

Transmission media needed to perform the test measurement data and to determine the performance of an existing wireless network in two different rooms. One of the transmission medium that can be used is the access point that has been connected to the server computer. The access point is required to emit a wifi signal so that the client computer can access to the server computer. Testing wireless network performance could be the solution to determine the performance of wireless networks.Implementation of wireless network performance testing used a server computer, the client computer and an access point. Testing is done by analyzing the parameters of Quality of Service (QOS) including delay, packet loss, jitter, throughput, signal strength, upload and download speeds. The tests are carried out in two different rooms and each room is done testing on two different access point placement. The method used was study of literature, network design and implementation of wireless network testing.On test results performance of a wireless network in a room divider wall first obtained on the current average, the signal strength is weak, and the barrier wall 2 obtained test results on good average, with the signal strength is good, the barrier triplex 1 obtained test results nice average and signal strength, as well as on limiting triplex 2 obtained very good results and also good signal strength. Overall wireless networks in two different rooms is able to perform well, but the barrier at about access point makes wireless network signal is disrupted and it can affect the performance of wireless networks.

Abstract

Servers 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.
