ABSTRACT This study discusses the role of public speaking skills in encouraging the effectiveness of academic presentations in students of the Faculty of Economics and Business. State University of Jakarta. This research uses a quantitative approach with a survey method. With a total of 50 students who became respondents in this study which was then tested using SPSS software, the results showed that public speaking skills remain an important factor in academic presentations to be effective. Therefore, training and development related to public speaking are needed to encourage the improvement of the quality of student presentations in the academic environment. Keywords: Public Speaking Skills. Academic Presentation. Students Yayasan Amanah Nur Aman Sabrina Alsya Rahmadhania et. all | The Role of Public Speaking Skills in Enhancing Academic Presentation Efectiveness INTRODUCTION If you hear the word public speaking, it must be familiar. Especially in this day and age, everyone is required to be able to convey opinions, ideas, ideas, or information clearly with a reliable source in public. Because actually having good public speaking skills is not only necessary for someone with a professional profession, but also important for the general public because it will be needed and helpful in various aspects of life. For example, in the context of students, this ability is very necessary because in the lecture process they will be asked to make individual and group In fact, the presentation will later become one of the assessment indicators that lecturers will give to their students. In previous research, it was proven that with the increase in students' ability to convey ideas, information, and so on well, their confidence to speak in public will increase (Muchlis and Pujianto. This is what makes public speaking skills important in terms of communicating orally in In addition, when making presentations, the role of public speaking is as a means for effective delivery, achieving goals in communication, and successfully influencing the audience (Ningsi et al. In making presentations, there are various methods that can be used and applied. For example, reading material, memorizing material, recording main ideas, and improvising material when delivering (Setiyawan and Apriliyana, 2. On this basis, the researcher is interested in conducting research related to this topic. Previously, pre-research was conducted on several students of the Faculty of Economics and Business. State University of Jakarta and the results showed that there was a positive correlation between public speaking skills and academic presentation skills. Most of the respondents already have confidence and good public speaking skills when doing academic presentations. However, there are still students who are constrained in managing their anxiety. Thus, this finding shows that there is still a need for training related to public speaking skills, so that they can better control themselves when speaking in public. Therefore, this study was conducted to determine and measure how big the role of public speaking skills in increasing the effectiveness of academic presentations of students of the Faculty of Economics and Business. State University of Jakarta. RESEARCH METHODS In this study, a quantitative approach was used with a survey method that was distributed directly online to respondents. This research falls into the category of associative quantitative research because it aims to see the cause-and-effect relationship of two variables. More specifically, the purpose of this study is to analyze the role of public speaking skills . ndependent variabl. on the effectiveness of academic presentations . ependent variabl. With the survey method, researchers can measure how big the role is through statistical calculations. The intended population in this study are active students from various study programs at the Faculty of Economics and Business. State University of Jakarta. With the purposive sampling technique used, making respondents in accordance with the criteria relevant to this study, namely students who are at least in the second semester in college. So that at least they have academic activities that involve academic presentation in the learning process. A total of 50 respondents have participated and in accordance with the criteria of this study. In collecting data, the questionnaire was distributed online through Google Form which has been compiled into a Likert Scale with a choice of five answers, namely point 1 for Strongly Disagree to point 5 for Strongly Agree with each variable containing 10 statements as measurement material relevant to public speaking skills and the effectiveness of academic presentations. After that, the data that has been collected will be analyzed using SPSS software with various The initial stage will be validity and reliability tests that will be adjusted to the needs of the Then the classical assumption test is carried out to calculate the relationship between the two variables. And the last is a simple linear regression test to show the magnitude of the role of public speaking skills in realizing effective academic presentations.

Based on the validity test carried out, there are results that have been listed in tables 1 and 2. It can be seen that all statements on both variables are declared valid as evidenced by the calculated r value of each statement greater than r table of 0. Then for the significance value is also smaller than 0. 05 in accordance with existing rules. For variable X . ublic speaking skill. , the r value ranges from 0. 520 to 0. While for variable Y . ffectiveness of academic presentatio. has a calculated r value ranging from 0. 442 to From these values, it shows that each statement item has a strong enough correlation so that it can measure its construct appropriately. Therefore, the questionnaire instrument used can be declared to have good construct validity. Reliability Test Table 3. Reliability Test of Variable X Number of Statement Cronbach's Alpha Condition Description 0,889 Reliable Table 4. Reliability Test of Variable Y Number of Statement Cronbach's Alpha Condition Description 0,843 Reliable Furthermore, the reliability test was conducted to determine the consistency of the instrument. Tables 3 and 4 show that both variables are reliable. Variable X which has 10 statement items has a Cronbach's Alpha value of 0. 889, while variable Y with the same statement items gets a Cronbach's Yayasan Amanah Nur Aman Sabrina Alsya Rahmadhania et. all | The Role of Public Speaking Skills in Enhancing Academic Presentation Efectiveness Alpha value of 0. It can be seen that both variables have exceeded the minimum limit of the reliability standard, which is 0. That way, all statement items for each variable are able to provide consistent and stable results if re-measured. So based on the validity and reliability tests, it can be concluded that the instruments from the questionnaire in this study are valid and reliable and are suitable for further analysis.

Then, the calculated t value of 5. 359, the calculated F value of 28. 721 with a significance of 0. 000 shows that the influence between variables is strong and mutually influencing. Thus, public speaking ability has an important role in improving the effectiveness of academic CONCLUSIONS The results of this study indicate that public speaking skills have an important and significant role in the effectiveness of student academic presentations. Although not completely dominant, public speaking skills remain an important factor in supporting the successful delivery of material during academic presentations effectively. Therefore, this study confirms that training and development of public speaking skills are needed as part of the learning process in order to improve the quality of student presentations in the academic environment.
