The use of persuasion theory is extremely important in daily life. Persuasion is crucial in situations other than marketing campaigns or political campaigns. Disseminating information to the general public and researching shifts in social norms and values both require persuasion. Aristotle's rhetorical triangle—ethos, pathos, and logos—is one of the persuasive techniques that have a significant impact on the communication industry. Aristotle's rhetorical triangle has been the subject of numerous studies, but few have addressed the problem of message delivery, particularly in digital public service announcements. The writer was encouraged to hold an ABDIMAS activity entitled "The application of Aristotle's rhetoric as a persuasive strategy for public service messages by Gen Alpha" at SMA Fons Vitae 1 Matraman, East Jakarta. The participants who attended were 22 people, 11 men, and 11 women, a combination of students from grades X to XII who were members of the English Club. The ABDIMAS activity which was held on Thursday, March 13, 2025, combined lecture technique and direct practice. From the results of the practice, it was found that all participants were able to apply Aristotle's rhetorical triangle persuasion strategy, with the most dominant strategy used being logos.

Language plays a crucial role in communication as it occurs in every individual's or group's interaction. When visiting a country that speaks a foreign language, it is essential to effectively communicate in that language. This research studied international students who qualified to study abroad yet still experienced some language barriers while living in Australia. This study aims to find what are the types, effects, and their strategy to prevent the language barrier they experienced. A qualitative approach was applied in this research and semi-structured interviews were conducted with 3 Indonesian students who study in Australia. The result shows that the types of language barriers faced by the participants were: technical jargon, badly expressed message, and unclarified assumptions. Then, confusion was the primary impact of the language barrier on each interviewee. Lastly, the strategies they used to prevent the language barrier were: speaking slowly and clearly, asking for clarification, frequently checking for understanding, and being patient. In addition, it is suggested that international students find out more about the culture through local television movies or series so that they become familiar with the local terms.
