Abstract: Piala dunia U-20 merupakan ajang perlandingan sepak bola lingkat internasional dikclola oleh PSSI, dimana Indonesia sebagai tuan rumah di tahun 2023. Namun sangat disayangkan, FIFA membalalkan Indonesia sebagai tuan rumah dan harus mengikuti kualifikasi agar dapat bermain di turnamen tersebut dikarenakan adanya penolakan terhadap kedatangan tim nasional negara Israel ke Indonesia olch beberapa pihak termasuk public figure poliitk schingga mcnimbulkan kericuhan dan amarah dari masyarakat. Dalam penelitian ini, algoritma K-Nearest Neighbors (KNN) digunakan sebagai metode untuk menganalisis sentimen terkait pembatalan piala dunia U-20 tahun 2023 pada akun Instagam public figure politik. Instagam menjadi media sosial yang sangat populer saat ini. Penelitian ini menggunakan metode KNN dimana sebclum perhitungan KNN, terlebih dahulu dilakukan proses preprocessing yaitu cleaning, case folding, normalization, stemming, filtering.tokenezing, TF-IDF yang kemudian dilakukan proses labeling data. Data yang digunakan sebanyak 2994 komentar. Dalam konteks klasifikasi menggunakan metode K-Nearest Neighbor (K-NN) dimana menggunakan berbagai nilai k yaitu 1,2,3,4, 5, 6, 7, 8, 9, 10. Proses ini melibatkan perbandingan pada tahap pengujian guna mencapai tingkat akurasi yang optimal, dan hasilnya dievaluasi menggunakan confusion matrix. Dari pelabelan, diketahui bahwa kelas sentimen negatif lebih unggul dengan jumlah 273 dibadingkan dengan sentimen positif yang hanya berjumlah 257 sehingga dapat diketahui jika sentimen masyarakat terhadap tokoh politik adalah negatif. Dari hasil pengujian diperoleh hasil dengan nilai k= 3memiliki nilai akurasi yang optimal daripada nilai k yang lainnya yaitu 93%. The U-20 World Cup is an international level football competition managed by PSSI, where Indonesia will be the host in 2023. However, it is very unfortunate that FIFA has rejected Indonesia as the host and they have to take part in qualifications to be able to play in the tournament due to rejection of their arrival. Israel's national team went to Indonesia by several parties, including political public figures, causing chaos and anger among the public. In this research, the K-Nearest Neighbors (KNN) algorithm is used as a method to analyze sentiment related to the cancellation of the 2023 U-20 World Cup on Instagram accounts of political public figures. Instagram is a very popular social media nowadays. This research uses the KNN method where before calculating the KNN, a preprocessing process is first carried out, namely cleaning, case folding, normalization, stemming, filtering, tokenezing, TF-IDF and then the data labeling process is carried out. The data used was 2994 comments. In the context of classification using the K-Nearest Neighbor (K-NN) method which uses various k values, namely 1,2,3,4, 5, 6, 7, 8, 9, 10. This process involves comparisons at the testing stage in order to reach the level optimal accuracy, and the results are evaluated using a confusion matrix. From the labeling, it is known that the negative sentiment class is superior with 273 compared to positive sentiment which only numbers 257, so it can be seen that public sentiment towards political figures is negative. From the test results, results obtained with a value of k = 3 have an optimal accuracy value compared to other k values, namely 93%.
