The data that is proper to use for sentiment analysis are 618 data tweets which consists of 237 positive data tweets and 389 negative data tweets taken during December-January 2021 using Twint application in Python. Data tweets that are taken goes through pre-processing stage which consists of case folding, data cleansing, tokenization, normalization, stopword removal, and stemming. After pre-processing, data weighting is done using Term Frequency-Inverse Document Frequency (TF-IDF) and classification is done using the method of K-Nearest Neighbor with cosine similarity to calculate the distance between documents. Based on the evaluation results using confusion matrix, the highest accuracy is 83,1% when k=9, the highest precision 2 is 66,7% when k=5 and the highest recall is 87,5% when k=9.en_US
