This article aims to describe the influence of social media on the formation and spread of slang among students at Muhammadiyah University, Maumere. Social media, such as Instagram, TikTok, and Twitter, are not only a means of interaction, but also a major catalyst in creating and disseminating new terms. This phenomenon reflects students’ linguistic creativity and is also a reflection of the dynamics of digital culture. In the context of Maumere Muhammadiyah University students, the use of slang is not just a trend, but also a tool to adapt to a dynamic social environment. New terms that are popular on social media are often adopted in daily conversations as symbols of modern and contemporary identity. However, this phenomenon also raises challenges, especially related to the preservation of formal language and traditional values in communication. This article discusses the characteristics of slang that emerges from social media, its role in forming social identity, and its impact on the use of formal language. In conclusion, social media plays a significant role in shaping student communication patterns, but efforts are needed to maintain a balance between language creativity and the use of standard language in formal contexts.

The study used a qualitative descriptive approach method. The purpose of this study was to determine the acquisition of slang lexicon by teenagers on the X application, providing insight into language in the modern era, the role of social media in language development, understanding slang in forming individual and community identities in social media, and understanding rapid language changes due to technological developments. Language variety is a variation of language that differs according to the context of use, including the relationship between the speaker and the listener. Slang, as a form of variation that continues to develop, is heavily influenced by social media, especially the X application (formerly Twitter), which is the main platform for teenagers. Through interactions on social media, users learn and absorb new vocabulary quickly, which shapes their social identity. This study used a qualitative approach to analyze the slang lexicon that appears in the application, finding categories such as abbreviations, foreign words, and phonological changes. Although slang enriches communication, there is a risk of reducing the use of formal language that needs to be balanced with language literacy education.

The growth of the internet has influenced the tourism industry because the internet makes it easier for individuals to obtain reviews about places to visit and because the internet is a tool used by tourist site managers to assess the quality of their offerings. The increase in the number of tourists of almost two million in just three years in West Sumba is proof of this influence. Social media is a tool that people use to interact with each other online; some people have multiple accounts on platforms such as Instagram, WhatsApp, Facebook, Telegram, Twitter, and so on. Tourists can receive recommendations for tourist attractions based on price and type of trip desired through a tourist attraction recommendation system that uses the KNN algorithm. Three factors were used in this research: activity, type of tourism, and type of price.

This study explores the role of sentiment analysis as a predictive tool for understanding and forecasting product launch success in the digital market. Sentiment analysis involves the classification of consumer sentiment expressed on social media platforms such as Twitter and Instagram, and it can significantly impact businesses by predicting consumer behavior and product performance. The research highlights the relationship between social media sentiment and product success, demonstrating that positive sentiment is strongly correlated with higher sales and consumer engagement, while negative sentiment can lead to declines. Machine learning models, including Support Vector Machines (SVM) and Random Forest, were employed to classify sentiment from large volumes of social media data and correlate it with product performance indicators such as sales volume and consumer interaction. The study found that sentiment analysis models were highly effective in predicting product success, with positive sentiment generally driving product profitability and negative sentiment posing a potential threat to brand reputation. Moreover, the analysis showed that social media sentiment provides real-time insights into consumer perceptions, enabling businesses to quickly adjust marketing strategies and product development plans. These findings underscore the importance of integrating sentiment analysis into product launch evaluations and strategic decision-making. Future research should explore the integration of sentiment analysis with other predictive market models and investigate the effects of fake reviews and post-purchase consumer behaviors on product success.
