Abstract

Many people are eager to learn more about the world of farming, not just knowing the name and shape of the animal. However, not everyone can travel to the farm to learn about the life cycle of the animal. One way that can be used to provide a learning experience about the life cycle of living beings in the fastest way is through a game. One of the game’s genres that can be used to provide entertainment and educational aspects to the players is a life simulation. As a life simulation game, the data used is from the real studies of sheep. To give a more realistic situation, this game has a fuzzy state machine to determine the behavior shown by the animals when being approached by the opposite sex.By creating the simulation of sheep with three-dimensional interface, the player will enjoy the gaming experience more similar to the real world. This will give more pleasure to the player. This game was made using the Unity Engine and scripting using C # with MonoDevelop. From the test results, the majority of sheep AI performance is partly influenced by changes in the inputs necessary for the calculation of fuzzy and largely influenced by the interaction of the player in the game.

This thesis discusses the application of Indonesian editor with spell checker and diction recommendation features in IndonesianThe process is carried out as follows: users opens a file or typing in the editor, words input will be checked with Apache Lucene, and Lucene will crawling to all of the data and give the recommendation base on the weight (Leveinsthein Algorithm) and if a user opens a file, the application will perform spell checking using Nazief and Adriani algoritm. The result of this process is the result of input that is underlined words that is not in accordance with Indonesian, or suitable recommendation result by Apache Lucene. Input could be words or .doc file. As Output will be written in .doc file and the spell checking results and words recommendation will be shown in editor as the user types. This application is built using Java programming language and Android Studio as the IDE.The test result shows that the accuracy of the Nazief and Adriani Algorthms still need to be improved, word length and word complexity also affects the time in the checking process, for example: to check documents with 100 words, there are various of time from 1.48 minutes to 3.3 minutes.
