Abstract

This study aims to explore public perceptions regarding the issue of Pertamax fuel adulteration, a topic that has sparked widespread discussion on YouTube, by employing sentiment analysis techniques based on the Naive Bayes algorithm. This issue has attracted significant public attention and become a trending topic on social media, particularly on the YouTube platform. The data analyzed in this research consist of user comments responding to the issue. The Naive Bayes algorithm is used to classify sentiments in the comments into three categories: positive, negative, and neutral. To address the imbalanced distribution of data, the Synthetic Minority Over-sampling Technique (SMOTE) is applied. The results show that before applying SMOTE, the model achieved an accuracy of only 48%, with a precision of 0.48, recall of 0.36, and an F1-score of 0.41 for the negative category, as well as a precision of 0.48, recall of 0.56, and an F1-score of 0.52 for the positive category. After implementing SMOTE, the model's accuracy increased significantly to 88%, with a precision of 0.91, recall of 0.93, and an F1-score of 0.92 for the negative category. For the positive category, precision improved to 0.80, although recall decreased to 0.75, yielding an F1-score of 0.77. The average precision, recall, and F1-score (macro average) after applying SMOTE reached 0.85, 0.84, and 0.85, respectively, representing a substantial improvement compared to the results before SMOTE. This study highlights the importance of using SMOTE to enhance sentiment analysis accuracy, particularly in addressing class imbalance issues within the dataset.

Abstract

Di era globalisasi ini, perkembangan teknologi informasi yang pesat telah membawa perubahan signifikan dalam berbagai proses bisnis, termasuk pengelolaan inventaris. Penggunaan teknologi komputer terbukti meningkatkan kecepatan, akurasi, dan konsistensi dalam pengolahan data. PT. Bank Pembangunan Daerah Sumatera Selatan dan Bangka Belitung menghadapi tantangan dalam pengelolaan inventaris kantor yang menggunakan sistem manual berbasis Microsoft Excel, yang mempengaruhi efisiensi dan akurasi data inventaris. Penelitian ini mengusulkan pengembangan sistem manajemen inventaris berbasis web menggunakan framework Laravel dan database MySQL dengan metode Agile. Sistem ini menawarkan pembaruan data secara real-time, mengurangi kebutuhan pengecekan fisik barang, dan mendukung pengelolaan aset yang lebih baik. Diharapkan bahwa penerapan sistem ini akan meningkatkan efisiensi, akurasi, dan pengelolaan inventaris yang lebih terorganisir, serta mendukung kelancaran operasional perusahaan.
