Abstract

Abstrak- Mobile JKN merupakan aplikasi yang dibuat oleh BPJS Kesehatan untuk memudahkan beberapa masalah administrasi peserta, sehingga peserta tidak perlu datang ke Kantor Cabang karena dapat dilakukan atau diselesaikan dengan aplikasi ini. Tetapi aplikasi ini tidak jarang memiliki beberapa kendala, sehingga menimbulkan penilaian yang kurang baik terhadap pelayanan tersebut. Media sosial Twitter cocok digunakan untuk tempat mengungkapkan perasaan seseorang, membagikan dan mendapatkan informasi terkini, serta komentar atau opini tentang segala hal yang banyak dikenal dan penggunanya pun cukup banyak. Salah satu cara untuk mencari komentar atau opini dari penulis tentang suatu hal, entitas atau subjek tertentu sehingga dapat diklasifikasikan menjadi opini positif, negatif ataupun netral dapat digunakan dengan Analisis Sentimen. Analisis sentimen dapat dilakukan dengan menggunakan Algoritma Naïve Bayes. Naïve Bayes yang nantinya akan mengelompokkan berdasarkan peluang atau probabilitas, dimana dihitung sekumpulan probabilitas dengan menjumlahkan frekuensi dan kombinasi nilai dari dataset yang diberikan. Pada proses implementasinya, dataset yang didapatkan berjumlah 1001 tweet, dengan perbandingan data training dan data testing yaitu 80:20. Penelitian ini menghasilkan 488 tweet positif, netral 193, dan negatif 320. Sedangkan untuk menghitung akurasinya menggunakan confussion matrix dengan akurasi yaitu 69.65%, presisi 62.18%, recall 60.44%.

Abstract- Mobile JKN is an application created by BPJS Health to facilitate several administrative problems for participants, so that participants do not need to come to the Branch Office because they can be done or resolved with this application. However, this application often has several problems, giving rise to an unfavorable assessment of the service. Twitter social media is suitable for use as a place to express one's feelings, share and get the latest information, as well as comments or opinions about everything that is widely known and has quite a lot of users. One way to look for comments or opinions from writers about a particular thing, entity or subject so that they can be classified into positive, negative or neutral opinions can be used with Sentiment Analysis. Sentiment analysis can be done using the Naïve Bayes Algorithm. Naïve Bayes will then group based on chance or probability, where a set of probabilities is calculated by adding up the frequencies and combinations of values from the given dataset. In the implementation process, the dataset obtained was 1001 tweets, with a ratio of training data and testing data of 80:20. This research produced 488 positive tweets, 193 neutral and 320 negative. Meanwhile, to calculate the accuracy, a confusion matrix was used with an accuracy of 69.65%, precision 62.18%, recall 60.44%.

Keywords: Mobile JKN, Twitter, Sentiment Analysis, Naïve Bayes Classifier.
