Publisher : Universitas Muhammadiyah Sidoarjo

Indonesia has a diverse culture from the form of creation, work, and intention, but over time Indonesian culture is eroded by the sophistication of the times. Using entertainment media such as games will be able to provide knowledge about culture through the game and can develop morale, using 3D interactive design of an object such as historical heritage will look close to real and with the Aritificial Intelligence (AI) used in the opponent will make the game that is played becomes fun or not monotonous. This study uses the Fuzzy State Machine (FuSM) method which aims to shape character behavior like human like behavour. The results that can be generated from FuSM are behavior that changes according to the conditions and rules that have been determined. This is where the AI that is formed will not always be the same in the same situation, all will be different depending on the conditions and rules that exist.

E-Complaint Data is a collection of data which contains comments or complaints from students towards the University. Lots of comments - comments that occur in the university environment about the performance facilities of lecturers etc ... Text mining is also known as text data mining or knowledge search in a textual database is a semi-automatic process of extracting data patterns. The purpose of text mining is to get useful information from a collection of documents. In this study using the naïve Bayes method with TFIDF weighting features. The stages will be taken to determine its classification. First is taking data from the E-Complaint System then the data will go through the preprocessing stage using literary libraries, after going through the preprocessing stage the data will be divided into 2 namely training data and testing data. Then the training data will be carried out the TF-IDF weighting process up to the probability, if it has, the next is to process the testing data by determining priors. Next is the data testing stage between the testing data and the training data, the results of the testing data will come in the form of a predetermined category. The trial results show that the classification of complaints with the naïve Bayes algorithm and with the TF-IDF feature and literary libraries in the preprocessing process has an average accuracy that is quite high at 82%.

Publisher : Universitas Muhammadiyah Sidoarjo

This study aims to analyze sentiment towards the transfer of new capitals derived from comments on the tweeter. The method used in this research is Naïve Bayes Classifier, a classic method that has a pretty good accuracy. Naive Bayes Classifier is a probabilistic classification based on the Bayes theorem, taking into account naïv independence assumptions. In addition to using the naïve bayes method, in this study the researchers also used word weighting. The weighting word used is TF-IDF, which is a combination of term frequency and inverse document frequency. By using 3 testing methods, namely Confusion matrix, Precission and Recall, and K-Fold Cross Validation. The results obtained in this study are 3 document classifications, namely Positive, Negative and Neutral. Testing is done by dividing the document into 2 subsets, namely training data and test data and the resulting accuracy of 64.6%.

Comparative Analysis of Text Mining Results With Tf ldf Features and SQL Like Operator in Indonesian News Search Riwa Rambu Hada Enda; Fajar Hariadi
JOINCS (Journal of Informatics, Network, and Computer Science) Vol 3 No 1 (2020): April
Publisher : Universitas Muhammadiyah Sidoarjo

Research on the implementation of text mining uses the TF IDF method to be used in the Information retrieval / Indonesian news search feature. The dataset used was sourced from NewsAPI and built a Codeigniter based website named "News Plus Six Dua". This study also uses the Vertor Space Model (VSM) method to overcome the weaknesses of the TF IDF method at the time of the sorting process. The results of this study explain that the search by the TF IDF method has higher accuracy when compared to SQL like operators. TF IDF produces a percentage of precision 100% and recall (sensitivity) 66.7% on searches with the keyword "Indonesian soccer schedule" while SQL like operators do not display search results or equal to 0%. But the TF IDF method has the disadvantage of running slower than SQL like operators. This has been tested using either the number of words or terms entered, the number of datasets, and the location of access. At the location of access, access via hosting is monitored faster when compared via localhost.

Slingshots are also a type of traditional weapon used by ancient people to protect themselves from danger and to hunt small birds. Not only that, slingshot is also a toy of Indonesian children in ancient times. But in this modern era, catapults are rarely played by children and are used by farmers to drive out rice field pests. To be able to preserve the slingshot's traditional weapons, a media update is needed. Even though we don't use and play the slingshot, we can find out how to use it through a medium. Today through digital forms of media such as smartphones can help us so that slingshots can be reused, namely through the form of games on smartphones. This study uses the Research and Development method with addie models (Analysis Design Development Implementation Evaluations) that are appropriate and efficient with the stages in making games. The results obtained are games that are made to be applied to various age groups, especially children. The community responded positively because the games made were positive and could re-introduce traditional games that were developed into more modern games and as a medium of entertainment for the community. So that people will get to know traditional slingshot weapons.
