Abstract

Based on current data, there has been an increase in social media users, which shows that more and more people are using social media as a place to express themselves and their emotions. This will generate thousands of tweets within a day. The tweet data is processed so that it is useful for stakeholders who need it to help them make a decision. Because sentence structures on social media are often irregular, pre-processing is necessary to make tweet sentences normal. Stemming and Stopwords are pre-processing techniques that are widely used in sentiment analysis. In previous studies, there were indications that its use did not have a significant effect on accuracy. In this study, the authors divide it into four models: using stemming and stopwords and without using stemming and stopwords. Data using stemming gets the best results with an f1-score of 65%. These results indicate an increase in performance in the use of stemming and stopwords using Multi-class Naive Bayes

Abstract

This research develops a teaching tool for Kirchoff's law on the concept of direct current circuits, which is motivated by the minimal number of tools and the lack of tools available in schools as learning media and to improve science process skills. The development of the tool lies in replacing the input source with an adapter because the energy does not run out quickly, resulting in a more stable value. The research method used is development research from Akker with the type of development research model, which consists of introduction, prototype, summative evaluation, systematic reflection, and documentation. The purpose of this research is to test the feasibility, effectiveness and practicality of the developed teaching aids. The research subjects were 100 students from two classes. The instruments used were non-tests (guidelines for interviews, observations, and questionnaires) and multiple-choice tests. The results of the assessment of Kirchoff's legal aids were declared feasible, effective, and practical.
