Abstract

The list of academic advisor utility is an utility that was developed to help the administration process of computer science major. Previously, it's only used bubble sort sorting algorithm. We try to compare the bubble sort algorithm with selection sort and quick sort to determine the quickest algorithm which will be implemented in other major by searching the worst case (slowest execution time per unit) and best case (fastest execution time per unit). The result is quick < selection < bubble. Selection sort algorithm is proven to be the quickest when n < 26. But the  cademic advisor data that are used in the utility is more than 26. So in this research, the quicksort algorithm is the fastest algorithm.

Abstract

The excess of plugin is more practical because it does not need to create a web from the base, and web with attached plugin becomes better. Furthermore small in storage capacity. Plugin of seminar which has built has advantages from the system that already exist, conventional system is still using whiteboards and paper, plugin is successfully implemented into the web of Computer Science Department and dissemination of information about seminar schedule become more optimal, as well this plugin has facility of reminder for lectures and college student that related to the seminar.

Abstract

The development of educational game is motivated by low interest and desire of people to learn Aksara Lampung, therefore, in this case is required a learning system which is attractive and pleasant so it can attract people to keep follow the development of existing technologies, one of which is a learning system by using media of educational game. This research used eXtreme Programming (EX) method and was designed by using Unified Modeling Language (UML). This application tested by using Black Box Testing method with the approach of Equivalence Partitioning (EP) and the calculation of Likert Scale. On the other side, based on the results obtained from the questionnaire, this application is user friendly application (with an average value of 77% / Excellent).

Abstract

Most of the system or results of application the final project and computer thesis of science students that is creating applications that can help the performance of the Department. However, applications made have not been utilized properly, only presented and stored in the library only. Besides, container or a place to attach the application provided are difficult for users because there are settings for connecting to the ftp server. This study built an Application Management System (AMS) as one of the solutions that can be implemented to overcome these problems.AMS is a software used to organize the content. AMS facilitates the application that will be displayed as content on the main website. Implementation AMS of the content on the website using PHP programming language and MySQL database. The test results using Equivalence Partitioning (EP) shows that the AMS has been built to facilitate the user in posting applications. Applications that are embedded into websites using AMS can be run properly.Keywords: application management system, equivalence partitioning, website.

Abstract

Radio Streaming is use technology for sending an audio file simultaneously on multiple computers on a network by using a small data packets and generates output semi-real time. In the process of streaming, a music file will sound when the computer starts receiving the music file data. Shoutcast DNAS is a freeware that is used for streaming radio technology. Shoutcast help the user to provide an Internet Radio Private servers using software that has been provided. Winamp is a multimedia player device created by Nullsoft. The trial results of this study are the Application Streaming Radio can help the user to display the program content of radio, play and lay Radio Streaming and display e-mail addresses, website streaming and also Encoder used affects the occurrence of delay, the connection is unstable causing disconnection in automatic, processor speed and also the speed of the internet connection affects the buffering of streaming player or players. Keywords: Streaming Radio, Shoutcast DNAS, Winamp, Encoder.

Abstract

Perkembangan teknologi informasi terus meningkat seiring dengan kebutuhan organisasi dalam mengelola proses bisnis menggunakan berbagai sistem yang saling terhubung. Pada proses transmisi data antar sistem, dibutuhkan keamanan tingkat tinggi yang mampu menjamin integritas data dalam hal keutuhan dan konsistensi data, khususnya sistem keuangan yang memiliki data sensitif. Exposure data sensitif melalui Application Programming Interface (API) merupakan salah satu kerentanan pada keamanan sistem berbasis web. Man in the Middle Attack (MitMA) merupakan jenis serangan yang sering terjadi ketika transmisi data menggunakan API. Penelitian ini bertujuan untuk meningkatkan keamanan transmisi data pada Representational State Transfer (REST) API menggunakan enkripsi Secure Hash Algorithm (SHA)-512. Hasil penelitian menunjukkan bahwa penerapan enkripsi SHA-512 mampu meningkatkan keamanan transmisi data dari client ke server maupun sebaliknya. Pada metode POST, data request yang terenkripsi memiliki performa lebih baik 2,8% dibandingkan dengan data request yang tidak terenkripsi. Sedangkan pada metode GET, data request yang terenkripsi lebih lambat 12,5% dibandingkan dengan data request yang tidak terenkripsi. Hal ini dikarenakan adanya proses enkripsi dan dekripsi yang dilakukan server untuk mengelola response sehingga membutuhkan waktu lebih lama.
