Abstract

Learning English in class is often carried out in a conventional way such as explaining using a whiteboard, doing practice exercises with pen and paper, and memorizing material from a book / dictionary. Such conventional teaching and learning processes often make students bored and feel the material presented is difficult to understand. One way that can be used to overcome this problem is to create a tool that uses technology, such as games.Gra-Pe Warrior game which has an adventure game concept with penguins as the main character where each level of the player must answer questions about grammar.   Gra-Pe Warrior game has become a new learning that further increases motivation in learning. This is evidenced by the results of a descriptive questionnaire test which shows that> 90% of respondents are interested because learning in the form of games is more interesting because it is equipped with several questions about grammar at each door when leveling up.

Abstract

Preprocessing is an important task and step in Information Retrieval. Information Retrieval (IR) is used to decide which documents in a collection must be taken to meet the user's information needs. The comparison is done in 4 steps in preprocessing, namely Case folding, Tokenizing, Filtering, Stemming.All stages of the preprocessing are done manually during the teaching-learning process. The lecturer explained by writing and explaining one by one the correct words at each stage and students also manually reviewed each stage. Simulator is needed to help solve existing problems. The simulator has been successfully created by displaying 6 menus. The simulator has succeeded in outputting each stage according to the manual theory. From the results of the testing questionnaire,> 90% of respondents thought that using this simulator made it easier to work on the four stages of text pre-processing so that the time needed also became efficient.
