Abstract

Nowadays, technology is growing rapidly and becoming more sophisticated, especially communications technology. Information can be deployed without having to meet each other. No doubt that any confidential information sent over the Internet. Through various types of information is developing techniques for damage or maintaining the security of the dissemination of information on the internet.Securing data by using cryptography is needed for sending confidential data so that not everyone can access it. Process undertaken in this study is encrypted messages with MARS method. Input in an application that is designed in the form of plaintext messages or files to be encrypted, then the key to encrypt the message. This application is made with the Java programming language using NetBeans IDE 7.4.The test results indicate that the encryption with MARS method can be performed on any type of file (example: text file, song or audio file, video file or movie, etc.). Files can be decrypted back to normal if the password is the same as the password for the encryption.

Abstract

This thesis’ goal is to let computer recognize Javanese letters. Before a computer is able to recognize Javanese letters, segmentation and feature extraction process is needed. After the features of Java letters that have been segmented obtained, then the features will be processed using computer learning method so that the computer can recognize the letters.Input is in the form of .CSV file that contains features of the Javanese document image that had previously segmented. Output text is a text file that contains unicode representation letter from Java font and a .CSV file that contains the test and data classification results. This application is created with C# programming language and Microsoft Visual Studio 2013 IDE.As for the process that is done is as follows: prepare the .CSV file resulting from the extraction of features to be used as learning materials or trainer for computer learning network. After the trainer file ready, then the network will be trained. After the training is complete, the network can receive other data input, and then classify it according to what has been learned.Probabilistic neural network and ID3 used as computer learning methods, which after data testing, it is found that PNN give higher accuracy result than ID3.

Abstract

Strategy is one of the more popular video game genres. There are many factors that can affect whether a strategy game is good or not. Some of those are the graphics of the game, the menus and features, and also the AI inside the game. This game is made with that understanding.The game will be made with Unity Game Engine. ID3 and Backpropagation will be used as the AIs in this game. The game is divided into two parts, namely the exploration mode and the battle mode. In the exploration mode, the player can freely explore their surrounding environment, interact with NPCs, or encounter an enemy. Battle mode is a mode where the player fights the enemy they encounters. Battle mode will be played in a grid that resembles a chessboard. The game will go into this mode only if the player made contact with the enemy in exploration mode. When the battle is finished, the player will return to exploration mode.The resulting games are tested by playing the game from start to finish. From the results, it can be concluded that the game has implemented the general features of games in strategy and RPG genre.

Abstract

The training process is the most important thing to recognize something, because without the process training, it’s impossible to recognize something with what datas you have. The training process of Javanese letter has its own difficulty level for collecting the extraction feature datas that can be used for training process and it took a long time to do the training process. In this paper developed an application that can make the process training to recognize of Javanese Letter with the extration feature datas.The process is carried out as follows: image that has been previously segmented, then extract the feature datas and used it as input to begin the training process with  Elman Type. The Inputs are 88 atribute from data extraction features, that is the result of extraction features based on area-based theory from a picture of Javanese letter.  The result of the training process are some datas,  bias, weight datas, when the data is deemed to able produce good output, then it can be used for recognize the Javanese letter from the other source extraction feature datas . The output is some datas, like bias, weight, and Java letter recognition results stored in file.txt. This application is made to the programming language C # with Microsoft Visual Studio 2010 as the IDE.The results show that javanese letter recognition accuracy by using Elman reach 85.16 % .

Abstract

Development and competition in Indonesian University is extremely tight. Petra Christian University is also a Universitys with long-standing and well known to many people in Indonesia. Prospective students would like to see more clearly the shape, structure and atmosphere held at the University. Thus someone created a virtual map for Petra Christian University building by using a Head-Mounted Display Oculus Rift to display a simulation of the map Petra Christian University building. But the virtual map that has been created earlier is simply an empty simulation maps that contain only furniture - furniture and does not contain a virtual character, so that the simulation does not have any college atmosphere. So it was decided to implement a virtual character in a map that looks like a real simulation using a rule-based system.In the development of prior research program conducted every object in the form of the building, so hopefully the results obtained could resemble its original state. Giving materials to the models at the Unity are expected match the colors of the original state. Giving collision features intended to make the user cannot penetrate what as original state.Results on this program, the position and shape of character object in the building resemble the original state that existed at Petra Christian University. Time constraints in making become a major factor, so it’s cannot make the character more in detail. The whole room and the character of the building P 2nd floor has been made, there are only a few sections still incomplete, example on the large staircase of the building P and other small parts. Disadvantages of this program require computer high specification enough to run the program. This is because the resulting resolution on this program can be fairly large.
