Abstract

Penelitian ini mengkaji efektivitas algoritma Naive Bayes (NB) dan K-Nearest Neighbors (KNN) dalam analisis sentimen ulasan pengguna aplikasi Vidio di Google Play Store. Evaluasi kinerja kedua model dilakukan menggunakan berbagai metrik, termasuk akurasi, precision, recall, dan Area Under Curve (AUC). Hasil penelitian menunjukkan bahwa KNN mengungguli Naive Bayes dalam beberapa aspek penting. KNN mencapai akurasi 74.92% dibandingkan dengan Naive Bayes sebesar 71.32%. Dalam hal precision, KNN juga menunjukkan performa yang lebih baik dengan nilai 76.52%, sementara Naive Bayes mencapai 71.61%. Meskipun demikian, kedua model menunjukkan kinerja yang sebanding dalam hal recall, dengan KNN mencapai 72.54% dan Naive Bayes 71.46%. Yang menarik, kedua model memiliki nilai AUC yang sangat tinggi dan hampir setara, yaitu 90.10% untuk KNN dan 90.00% untuk Naive Bayes, menunjukkan kemampuan yang sangat baik dalam membedakan sentimen positif dan negatif. Berdasarkan hasil evaluasi secara keseluruhan, algoritma KNN lebih direkomendasikan untuk implementasi analisis sentimen pada ulasan pengguna aplikasi Vidio.

Abstract

This study aims to solve the problem of determining scholarship recipients through a decision support system with output in the form of ranking using the Combined Compromise Solution Method. The application of the Combined Compromise Solution (CoCoSo) method in determining scholarship recipients will result in a comparison of the scores of all students who register to receive scholarships from schools. So that through the decision support system developed it can produce prospective scholarship recipients according to predetermined criteria and the selection process does not take long because the decision support system built is equipped with a web-based application using Laravel 8 which is used to determine scholarship recipients. Calculations for determining scholarship recipients using the Combined Compromise Solution (CoCoSo) show that the results of calculating the final score of the 1st scholarship recipient received a final score of 2.7031 obtained by Dwi Adhawati, the 2nd scholarship recipient received a final score of 1.9111 obtained by Muhammad Ferdi, and the 3rd scholarship recipient with a final score of 1.8684 was obtained by Muhammad Irfan.
