Hoax News Detection in Indonesian Political Headlines Using Multinomial Naive Bayes
Isi Artikel Utama
Abstrak
Media sosial merupakan sarana pergaulan sosial secara daring di internet dimana para penggunanya dapat berbagi informasi secara bebas. Dikarenakan kebebasan yang dimiliki oleh setiap orang, maka tidak dapat dipungkiri bahwa beberapa masyarakat tidak bertanggungjawab melakukan penyalahgunaan media sosial sebagai tempat menyebarkan berita hoaks. Berdasarkan survei yang dilakukan DailySocial.id terhadap 2.032 responden pada tahun 2018 disimpulkan bahwa sebagian besar masyarakat Indonesia belum memiliki kemampuan untuk mendeteksi berita hoaks. Oleh karena itu, penelitian ini bertujuan untuk merancang dan membangun sebuah aplikasi deteksi berita hoaks yang menggunakan algoritma Multinomial Naive Bayes berbasis Android. Pada tahap perancangan, aplikasi didesain untuk menerima input berupa teks judul berita politik. Setelah itu, algoritma Multinomial Naive Bayes digunakan untuk melakukan deteksi berita hoaks dengan membandingkan teks yang dihasilkan dengan dataset. Dalam tahap pengujian, model algoritma diuji dengan menggunakan confusion matrix dan menunjukkan tingkat akurasi deteksi berita hoaks sebesar 88,9%, nilai presisi sebesar 93,33%, nilai recall sebesar 84%, dan f1-score sebesar 88,4%. Dengan adanya aplikasi deteksi berita hoaks ini, diharapkan mampu berkontribusi terhadap lingkungan daring masyarakat Indonesia dengan memverifikasi informasi terlebih dahulu sebelum membagikannya ke media sosial
