Community Activities Restrictions Enforcement (CARE) is one of the policies that the government has implemented in tackling Covid cases in Indonesia. Public opinion regarding this issue will generate various sentiments that can be analyzed. In this study, sentiment analysis will be carried out on public opinion regarding the increase in Community Activities Restrictions Enforcement to level 3 using the Multinomial Naive Bayes algorithm. The process consists of data pre-processing, word weighting with Raw Term Frequency, training and testing of the Naive Bayes model which later the accuracy results will be calculated using the K-Fold Cross Validation of 5 folds. This study produces an average accuracy of 0.78 with the addition of stop words and data normalization. This accuracy does not create much difference without using stopwords and data normalization with an accuracy of 0.79. The addition of stopwords and data normalization still does not produce a significant difference.]]>
