Abstract

Real estate has growth significantly in Indonesia recently, there are many new estates , apartment , shop for sale. There are several media used to advertise properties for sale, for example let’ say brochures , banners , newspapers , the internet . Among a lot of advertisement media , internet is the most effective because it does not need to pay extra fee for promotion , can load the images for the real estate , the number of people who access the Internet are very large , the search can be detailed based on user demand . Many real estate agents have promote their real estate on the internet. Therefore, this thesis tries to make an application that can help sellers to enter data from the real estate to be sold , and help potential buyers to search for properties in accordance with his wishes . Searches can be more effective in the presence of the coordinates on Google Maps as a property and a map service provider. The test results showed that the difference in screen resolution on Android devices can affect the appearance of the application on diferent device . Increasing number of data entered in the spinner will make the process of loading spinner itself is getting slow .

Abstract

The monitoring system is an important component that we need a system datacenter. Problem can be occurred if a datacenter system does not have a monitoring system. It could lead to be a problem for a network administrator to manage and monitor servers in a network.This thesis intends to make a system monitoring with monitoring tools namely Zabbix. Zabbix is a monitoring tools that have user friendly interface, and also can display some information needed to improve work of network administrator. Some features such as Telegram API and SMS API added in Zabbix.By doing so, Zabbix can send notification message to network administrator if trouble happens in network. The result shows by adding Telegram API and SMS API in Zabbix, network administrator can reveal network condition in real time.

Abstract

E-commerce sites in Indonesia offers many products with different prices. Consumers will find it hard to do a comparison of products by opening many existing e-commerce web. Therefore, a website portal is created for consumers to find and do a comparison of product from any existing e-commerce.The research focused on the feature for comparison between e-commerce products. Product comparison feature requires the server can retrieve product data from any e-commerce site and GSMArena. Then, process followed by parsing and processing on any e-commerce product data which has been established to be adapted to the product GSMArena.Based on the research, the time to get data e-commerce products and GSMArena products relies on the server's bandwidth and response time provided by each site. Products on each e-commerce have different product name from GSMArena, so the calculations is needed for the suitability of the product name between e-commerce and GSMArena.

Abstract

Internet is one of the fastest growing Information Technology. There is a lot of information which can easily be obtained through the Internet. Computer network system is needed for a person to use or access it. Along with the increasing number of Internet users, Petra Christian University has been doing various ways in using the internet well, such as increasing bandwidth and also replacing the Internet cable lines with fiber cable. However, there are still some problems like delayed access, etc.Therefore, this manuscript describes the development of bandwidth usage visualization to help Petra Christian University, particularly its network division, to obtain information about Internet bandwidth usage. The application which is used for generating the bandwidth usage visualization is TSTAT. TSAT is a tool for analyzing the traffic passing through the network layer and it can only be used in a UNIX-based operating system such as LINUX, OS X, and other variants. Collected traffic data will be analyzed using TSTAT and the results (in RRD format) are stored in mysql database. Storing to database is necessary since the RRD storage capacity is so limited (fixed) that, when the capacity is full, the earliest data will be overwritten. Afterward, data from database will be visualized by using RDDtools, and the display result in the form of graph will be presented on the website by using PHP language. Based on 15-minute traffic data capture, 95,8% of the traffic is TCP protocol, while 4,2% is UDP.

Abstract

Applications commonly used to solve the equations of dynamic analysis produce output that is less accurate because the use of mass implementation is less precise. Most of the applications are commercial and require the installation process before they can be used. The authors developed an application that uses website as the user interface, so that it can be accessed easily and does not require any installation process. The Website was created by using a more precise mass implementation so that the output becomes more accurate with simulated deformation and structure deflection.The Authors designed the website so that a user can have an account to make a project that is public or private, and an admin can manage the member data. Input process data are entered into tables with tabs such as node, properties, elements, joint mass, joint loads, ground acceleration, process so that the user can perform data input easily. Dynamic analysis calculation is performed by processing the input data using the Newmark method involving the creation of stiffness, mass, damping matrices the initialization of displacement, velocity, and acceleration the calculation of integration constants, the creation of element stiffness matrix, the calculation of displacement with time dependent, the calculation of displacement, velocity and acceleration.This dynamic analysis website generates outputs like all mentioned matrices in each element,  structure stiffness matrix, structure mass matrix, and displacement vector that conform with the exact solution. Results of displacement vector are  used to display the simulation of deformation and structure deflection at each time interval so the the structurak changes are observable from the beginning to the end.
