Abstract

One way that can be used to provide education in an interesting way is using game. A kind of game’s genre that can be used to provide entertainment and educational to the player is a turn-based strategy game. As a turn-based strategy game, Battle of Batavia requires AI as opponent which can take good decision for making and controlling units to make the game become more attractive.To create AI that can think well, an AI system that can think properly in game is created. The system uses genetic algorithm method to take decision in making and controlling units. In this thesis, there are 2 component created for this thesis, the first is the genetic algorithm system and the second is Battle of Batavia game.The results show that the genetic algorithm system can be developed so the AI can think much better by determining fitness criteria that affect on taking decision in making and controlling units. The results also show that the genetic algorithm system can make a better decision than random method on some in-game conditions.

Abstract

Currently, Petra Christian University Library provides a form for its users to recommend collection. However, this process is still done manually which causes frequent human error and difficulties in processing. In addition, user has not been able to obtain information about the loans status, including the return date and fines, if any. Based on those problems, the authors made a library user module application.This website application is created using Yii Framework and PostgreSQL database. For book collection recommendation system is based on the collection titles of user’s history loans which is processed by Solr application and user’s interest classification. The live chat feature is built using PHP Socket and HTML5 WebSocket.The final result of this application development is users can create a new collection recommendation and view collection recommendation that have been proposed along with its status. Users can also view their status and history loans as well as the book collection recommendations. Moreover, there is a live chat feature as a form of communication media between the library with its users interactively.

Abstract

The process of learning the lessons of history are often regarded as tedious, because the lessons of history study the events that happened in the past. Moreover, history lessons are also taught only by using an image or text. Therefore, in order that history lessons can become more attractive in it’s teaching, multimedia applications were made to teach the history interactively.This application resemble the learning system of Pattimura heroic history more interactive and interesting, because users are actively involved in the learning process. The teaching of the history starts from the birth of Pattimura, until death of Pattimura. In this application, there are also tests made, so the user can remember about the material that has been provided. This application is created using Adobe Flash CS6 and actionscript 3 as a programming language. Based on the results of testing of the applications and questionnaires, applications can be run by fully and strongly supports the process of understanding the historical material. This application adds to the interest in learning from the user, because of the interesting animation, and easy to use application. Users who doesn’t read narrative and do the applications in haste would have some difficulties to obtain a good final score.

Abstract

Game is an activity to find a new challenge or for having fun. Game have several genres like farming game, simulation, strategy, action, and many more. Each tipe has its own advantage and disadvantage like strategy genre is usually more challenging because its rather difficult hand have to stay focus to win. But other game like farming game is very fun but fell not challenging enough because usually farming game is very easy to play.Because of the difficulty reason, this game with farming and strategy genre have enemy that will attack the plants. Player also can protect the plants by killing enemy or by buying a tower that can attack enemy otomatically when an enemy come closer to the plants around that tower. This game is made by using Adobe Flash Professional CS6.From questionnaire average score 7.4, proofing that game with farming and strategy genre will become an interesting game that can be played.

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

Nowadays, Real Time Strategy Battle Arena is one of the most popular game genre. However, most games with that genre are only interesting if played together with another human. That makes those games less flexible since they can’t be played without another human or internet connection. Because of that, this thesis will create a game with Real Time Strategy Battle Arena genre with AI as the enemy where the enemy movements can be adjusted to approach human thinking ways. The enemy in this game will also be able to learn from each mistake. This thesis will use the method Adaptive Neuro Fuzzy Inference System. Test results show that the enemy was able to choose the best move possible, which suits the way humans think using Fuzzy Inference System. Neural System also modified the Membership  Functions of some Fuzzy Inference System input variable everytime the enemy is considered to make mistake to minimize similar mistakes when the game is played again in the future.
