Abstract

There are a lot of games with said genre that have been published for public and most of the games have a vs. Artificial Intelligence mode or AI for short. But the variations of the AI for Turn-Based Strategy genre are abundant. That is why hopefully this research will be able to help game developers who would like to make a Turn-Based Strategy game but have no idea which type of AI suits this kind of genre the most.The program, which is a game, that is made containts two AIs which are Genetic Algorithm and Fuzzy Logic. There are also 3 type of game modes that user can choose from, which are player vs. GA AI, player vs. Fuzzy AI, and the last one is GA AI vs. Fuzzy AI. The two AIs will be used to determine what type of unit the AI should make, who to attack and retreat from.From the results of the testcase which are a fight between the two AIs, genetic algorithm is more than able to make different kinds of unit, but it’s also capable of producing units that are suitable for the situation. Fuzzy logic consumes more time than genetic algorithm because of the huge amount of rules and genetic algorithm having some kind of threshold to get out of its iteration before it’s supposed to end that results in not-so time consuming process for each process. But on the other hand, if the fuzzy rules and its membership functions to be optimized, it’s almost guaranteed to produce better results.

Abstract

Internet that we use everyday is not fully secured from hackers that want to do cybercrime. Today, the Internet has become part of our daily lives as one of the means of communication in business as well as for individuals. But behind that there are many holes weakness of the system on the internet that can be exploited by the cracker for not good purposes, such as mail bombs, randomization of home page, data theft, password or credit card number. Most of security that people used in general is only the basic security system.This application is created using the programming language Python and html. The interface of app using Bottle Python Web Framework that can be accessed via IP Gateway. This is made in Raspberry Pi which is equipped with 16x2 LCD.The result of this development is we are able to use VPN and Tor simultaneously so that surfing / browsing on the internet becomes more secure and can access some websites that have been blocked like reddit forum.

Abstract

The Department of Infomatics Engineering and Business Infomation System of Petra Christian University has been using shared folder to save much of its operational data, like student scoresheet, list of active students, and photos of the department for exampl. But the shared folder is very vulnerable to be accessed by someone outside of the department if they had access to the computer  that have access to the shared folder easily. This shared folder also proven to be difficult to be accessed via smartphone, because there were no dedicated application that gives user access to use operational data easily.  This Private Cloud storage is using PHP and Javascript as its programming language for the web application and Java fo the mobile application. The server that used is dedicated solely fo this application and can be accessed via public IP.The result of the application development is giving user access of their files from their smartphones. This application also verifies the user so not anybody can have access to the files that’s stod in the storage.Users can also share ther files not only to another users, but also to some groups. Users can also edit thei documents right from the website

Abstract

To keep up with technological developments and people behavior, intelligent bot has become part of the business world which help them maintain good relation with their customer. Unfortunately, resource for intelligent bot in Indonesian language is very scarce compared to High Resource Language like English. Therefore further research about Natural Language Understanding in Indonesian language is needed. We use Convolutional Neural Network method to train our model. Model consist of embedding layer, convolutional layer, max pooling, flatten, dropout, and softmax layer. In the process of making model, there are many variable that can be tested such as dropout, number of filter, size of filter, etc. This research show that the amount and quality of data for each category can affect how a model understand the feature of each category which affect the overall precision. The quality of word2vec, one of the most important resource in the model can give significant impact on precision. The size of dropout can affect how the model understand the important feature of data. From various tests, we found that the best precision is 93 %.

Abstract

Dengue fever is a disease that caused by dengue virus. This virus is transmitted into human body through mosquito bites, aedes aegypti and aedes albopictus. This kind of mosquito are mostly found in subtropical and tropical regions, including in Indonesia. Almost every year, cases of dengue fever occur in Indonesia. Government’s effort to prevent dengue fever have been carried out. Following the development of technology, the government began to save patient data through their own health institution, the community health centers.However, the stored data cannot produce useful information instantly. The data must go through series of processes first before it can become informastion. Data processing methods that can be used are neural network. Because neural network have one function that is prediction. Then, the prediction data can be entered into a digital map for the mapping process. Mapping with digital map that have colors and display the level of sufferers can be said to produce useful information. The result of this program is a website that can display maps in the form of digital map, with data obtained based on prediction results using neural network method. So that later this website can help the government to take preventive measures againts dengue fever.

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. But for the view, the position of the layout as TextView , ImageView , videoview and also listview do not go well because of using density pixel (DP) so the size of each display device which has different pixel per inch (PPI)  will show different results.In addition on the device Samsung Galaxy S2 with Android 4.1.2 version  popup menu button located on the menu friends is not found.
