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

The development of smartphone technology and the need of people to gather information of places open chance to utilize augmented reality to help people get the information of a scene and see the scene through camera at the same time. The sensor-based AR system depends on GPS which is not always available. This research uses AR system using convolutional neural network for scene recognition.There are 45 network variations that will be tested to find the best combination. The different parameters that will be used are architecture, initialization method, and activation function that will be used. The architectures used are GoogLeNet and 2 variations of simplified GoogLeNet. The initialization methods used are random-based (Xavier and MSRA) and pretrained weights. The activation functions used are ReLU, PReLU, and ELU. The data augmentations used during training are random cropping, color balance, rotation, blur, sharpen, and brightness-contrast manipulation.Out of 1649 photos from 12 scene categories, 321 photos will be used for testing with variations on rotation (30 degrees interval), blur, sharpen, brightness, and contrast. Network with initialization method using finetuning on all areas of network and PReLU activation function has better average accuration.

Abstract

Today many manufacturers are competing to introduce their products. This triggers creativity in advertising. These ads are made in a variety of formats, ranging from print, video or any other media. But with the advent of various media formats of this ads, there is also a variety of constraints. One problem is that operating costs are also high enough to affect the price of the product is higher as well. The workings of this application is to scan the logo image objects and sent to the server for processing. The results of the process will be immediately sent back to the user of smartphones in the form of image information. Another function is to share information about the logos to others by using social media which connected with the internet. Based on the test results, the application can perform object recognition in the form of logos and displays related information. Accuracy of the normal scan success of 68.75%, accuracy in dim state of 0%, on a slope of 5 ° -30 ° by 60%, on the state of the logo is cut off by 20%, in landscape orientation by 40% and the small logo by 20%. Users can also add logos and information needed, and can also interact with other users through the comment feature.

Abstract

Physics class is one of difficult lesson for some junior high school students. When study physics, we need high comprehension and concentration because its got so many formula and explanation. One of way to study it excellently is using Multimedia.This application will resemble energy and pressure physics lesson become more attractive and interesting. in which players actively involved in the learning process. Starting from newton law, energy, and pressure for solid, liquid, and gas substance. There is also many simulations to help students understand the material. This application is created using Adobe Flash Professional CS6.From the questionnaire result, prove that the simulation strongly supports the process of understanding the material. Therefore user’s interest in learning is increased, coupled with the easiness of  application usage and user friendly.
