Abstrak.Currently, Twitter is not only a place to write microblogging messages, but has become a place where people express their aspirations. In 2018 the DPR received a lot of criticism from the public, especially through the twitter platform, therefore the data used in this study is the image of the community towards the DPR, which will be labeled positive and negative. The data used were 600 data consisting of 500 training data and 100 test data. The classification algorithm used in this study is K-NN and Naive Bayes, where K-NN is an algorithm that adheres to the concept of many neighborhoods while Naive Bayes is an algorithm that adheres to the concepts of probability and statistics. The final result of this study is to compare the accuracy of the two algorithms used, and after the data normalization processes to produce accuracy have been obtained results that K-NN get an accuracy of 80% at k = 19 and 20 while Naive Bayes get an accuracy of 77%. In this case the K-NN algorithm performs better than Naive Bayes because accuracy calculations can be performed repeatedly with different k until the best accuracy is achieved while the accuracy of Naive Bayes can only be done once. But even though K-NN has a higher accuracy than Naive Bayes, Naive Bayes still has a good performance in classification.
Peningkatan jumlah pasien COVID-19 menjadi perhatian utama para tenaga kesehatan, termasuk apoteker. Penelitian ini bertujuan untuk mengetahui bagaimana pengetahuan, kesadaran, dan praktik apoteker komunitas di beberapa wilayah di Indonesia terhadap wabah COVID-19. Penelitian ini didesain secara cross-sectional dengan pengambilan data dilakukan secara daring. Data diambil melalui survei menggunakan kuesioner yang terdiri dari delapan pertanyaan mengenai demografi dan 32 pertanyaan mengenai pengetahuan, kesadaran, dan praktik apoteker tentang pandemi COVID-19. Kuesioner disebarkan kepada apoteker yang memiliki Surat Ijin Praktik Apoteker (SIPA) aktif dan bekerja di komunitas. Sebanyak 116 apoteker di komunitas berpartisipasi pada penelitian ini. Hasil penelitian menunjukkan bahwa 99,14% (n=115) responden memiliki pengetahuan yang baik mengenai COVID-19 dan sebanyak 68,10% (n=79) responden memiliki kesadaran yang baik terkait COVID-19. Meskipun sebagian besar reponden menunjukkan nilai skor pengetahuan dan kesadaran yang tinggi, hanya 62,93% (n=73) responden yang selalu mempraktikkan protokol kesehatan saat memberikan layanan kesehatan di masyarakat. Mayoritas apoteker komunitas telah menunjukkan pengetahuan dan kesadaran yang tinggi terhadap wabah COVID-19. Diperlukan peningkatan implementasi protokol kesehatan di apotek sebagai upaya pencegahan penyebaran COVID-19.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
