Abstract

The increasing number of naturalized Indonesian national team players in the Garuda squad has triggered various reactions and opinions among the public, both pro and con. This study aims to identify and classify these sentiments, whether positive, negative, or neutral. The method used in this study is to use Naive Bayes because of its excellent ability to classify text based on the probability of word occurrence. In order to obtain more accurate results, several preprocessing stages need to be carried out through several steps, namely cleaning, case folding, normalization, stopword removal, tokenizing, and stemming on the data to be processed for maximum results from each stage. The results of the study showed that the majority of public sentiment tends to be more neutral towards the contribution of naturalized Indonesian national team players. To determine the percentage of results from the specified classification, a Confusion Matrix will be used. The results of the classification process using the Naive Bayes method produce data into 3 types, namely 33 positive classes, 357 neutral classes, and 13 negative classes with an accuracy value of 89%, precision 63%, recall 34%, and f1-score 33%. This sentiment analysis provides an overview of public comments regarding the presence of naturalized Indonesian national team players regarding public acceptance of the naturalization policy and can be input for PSSI in making decisions regarding the development of the national team in the future in order to improve the quality of the national team in the future

Abstract

Cybercrime is currently attracting worldwide attention as a type of international crime. Cybercrime via the Internet is a new type of cybercrime that has emerged as a result of advances in internet technology. This research uses qualitative methodology, which is related to the meaning, concepts, definitions, attributes, metaphors, symbols and descriptions of an object. The research results show that cyber security has an important role in improving information network security. Cybercrime and data privacy and security are closely related fields where ethics and technology interact. When using technology, ethics serves as a guide to reduce adverse impacts on data security and privacy. Data security and privacy go hand in hand with data protection. To prevent cybercrime and maintain data security and privacy, cyber security knowledge is essential. Data security for privacy is not only important, it is also essential for political, spiritual, religious and even freedom of expression. Ethics places great emphasis on protecting data security and blocking genuine, unauthorized access.
