Abstract

The development of education quaility in Indonesia can be done by improving the teachers’ quality. This development can be implemented through a certain regulation about teachers’ functional position and credit points’ system. Actually, this regulation is based on “Peraturan Menteri Pendidikan Nasional Nomor 35 Tahun 2010” which is talked about teachers’ functional position and the system of credit points. Yayasan Trampil Indonesia deeply supports that regulations by creating a functional training for teachers and having two supporting systems, namely e-admin and moodle.The difficult calculating system for credit points gives some problems to the teachers. That is why, teachers are not really focus in improving the education quality because they are too busy only in calculating the credit points. Therefore, we need a system to help the teachers in calculating the credit points.The system called e-portfolio. It will be connected with moodle and e-admin in order to calculate the credit points automatically. This connection uses the RESTfull web service. From the results of the questionnaire stated that this system help teachers to calculating the credit points. Indeed, this e-portfolio teachers can concentrate to improving the quality of education.

Abstract

The development of information technology is currently growing very rapidly. One of which is how to use messenger application on mobile device. Nowadays, messenger is one of the applications that are used to communicate by most people. This thesis aims to create a messenger application that can communicate between mobile devices especially devices with the Android operating system.In the design and implementation of this application, there is a server side comprising: Openfire server that serves as a protocol in the exchange of messages and the Apache server that serves to accommodate the user data. As well as the client side comprising: user interface display applications. This application provides features such as login, registration, chat, create groups and invite friends or group.From the results of tests on various Android devices with different versions and brands like LG G4 , LG G2 , Samsung Galaxy S2 ,Sony Xperia SP and  Sony Xperia Z3 Compact the application run well on all devices.

Abstract

Survey process in the field needs surveyor to writedown data manually on a paper. Manual data recording process will later be repeated to save it in the computer for a digital data. This process increases the possibility to have an error in the data input step from a handwritten data. Furthermore, there is a need to turn the survey data into a processed data for a decision making purpose by the survey administrator.Android is chosen as the mobile device platform in this thesis, because it is the most used platform in smartphones. Also, it answers the need of a surveyor in the field to easily carry the survey data. Server application uses Node.js framework to minimalize data process between platforms.There are two applications as the result, which are administrator web application and surveyor Android-based application. Web application is for creating, viewing, changing, deleting, and processing question and survey result data. Android-based application is to be used by specific surveyor in the field for answering many kinds of question types that is created in the web application.

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

The development and growth of Hospital X is getting bigger and bigger, and has information system in running their operational activities. Hospital X itself has a server to support its activities, especially the administration system which contains data about their patients. With the availability of the network at the Hospital X, either through Wi-Fi or an Ethernet cable, therefore it should be noted the bonds between networks and servers. Furthermore it is an important need nowadays to help minimize and anticipate the hacking crimes of the existing servers. One of the things that can be done is to monitor the administration and conduct vulnerability testing.Based on the background of the problem, it is necessary to evaluate server and network security using the vulnerability / penetration testing. In addition, this study also uses the guidelines of the CEH (Certified Ethical Hacker), Acunetix, and CISSP (Certified Information Systems Security Professional) modules. The testing of this thesis aims to find weaknesses in the administration system at Hospital X. Some problems were discovered after testing, which each of the weaknesses has different handling or treatment, physical security server weak, and unused opened ports that should not be open.The solution offered to solve these problems, are: the use of Acunetix and CISSP as a standard network security as the solution to anticipate weaknesses, to perform maintenance on a regular basis for the hardware, software, and network, to filter the existing port, to increase the level of security of the server, and to test security regularly and periodically, either through consultation with the related field experts or using a guide (like Acunetix, CEH, and CISSP).
