The Influence of YouTube Learning Media with Observation Method and Self-Confidence on Learning Outcomes of Heavy Equipment Technology

This study aims to determine the effect of YouTube media with the observation method and self-confidence on learning outcomes of Heavy Equipment Technology. The population in this study were students in 2019 in the Automotive Engineering Department, Faculty of Engineering, Universitas Negeri Padang with a sample of 32 students in the experimental group and 32 students in the control group. Samples were taken by cluster sampling technique. Data were collected through validated tests. The data analysis technique used the two-way variance test (ANOVA) and Tukey test. Before testing the hypothesis, the normality test and homogeneity test were carried out first. The results of data analysis showed that YouTube learning media and confidence in learning outcomes in the Heavy Equipment Technology course obtained a higher interaction with the results of the analysis of variance for the calculated F value = 4.24> F table = 3.97 at a significant level = 0.05. Thus, YouTube learning accompanied by high self-confidence obtains better learning outcomes compared to learning the observation method.


INTRODUCTION
Advances in science and technology increasingly encourage innovative efforts to use technology in the learning process.The industrial revolution 4.0 has changed the teaching system, mindset, and student actions in developing creative and innovative ideas in various problems, so an educational revolution must be carried out [1].Technological developments in the era of the industrial revolution 4.0 have changed the pattern of people's lives, every individual must follow technological developments and know how to use it so as to facilitate everyone's life [2].The development of technology has become a potential in various fields, especially in the field of education so that it must be responded positively and adaptively in responding to the challenges of the 21st century which is full of complexity [3], the use of technology in education has become a very important issue and is often discussed in various activities [4].
The existence of technology for the world of education is a means that can be used as a medium for delivering learning programs both unidirectional and interactively [5].In addition, the use of technology has enabled the emergence of distance learning and is driving greater innovation in creating teaching methods inside and outside the classroom [6].
In the field of education, lecturers are required to be able to use the equipment provided by the university.Lecturers can at least use efficient tools, but it is a must so that the expected goals can be achieved.Lecturers are also required to be able to develop skills in making learning media.One of the factors that influence learning outcomes is motivation and interest.The low motivation and interest of students during the Covid-19 pandemic, among others, during online learning activities, students actually showed an unenthusiastic attitude towards learning.Technology can be used to simplify the learning process, support notifications, evaluate learning activities, manage resources and create learning materials [7][8].Several studies have been conducted to explore students' readiness to study online in a higher education environment [9].The results of previous research conducted by [10].It can be said that in the midst of the COVID-19 pandemic that has hit the world, this is not the reason why students are so motivated to learn.While shortcomings have been found in practice, there is no choice but to optimize online learning, because in such an emergency situation, there is only Technology that becomes a bridge to transfer knowledge from lecturers to students.Another study shows that there is a significant relationship between academic independence and face-toface and distance learning outcomes [11].With high curiosity, this desire will encourage students to find what they want to know so that it can affect learning outcomes [12].Therefore, every educational institution has started implementing online learning using YouTube [15] Zoom Meeting [16] Google Meet [17] and other android apps.YouTube is the most popular social media today.Its popularity

RESULTS AND DISCUSSIONS
The data of this study consisted of three After learning with the learning process that applies the YouTube learning media and the Observation learning method, student learning outcomes will be obtained in the form of scores.The results are in the form of a collection of data obtained after each group is given treatment, which will then be used as material for analysis.
The description of the research data from the three variables will be expressed in the form of a measure of data concentration, including: a) the average, b) the standard deviation, (c) the mean, d) the highest frequency that appears.The distribution of data that will be described in a Learning media is a messenger technology that can be used for learning purposes in supporting the success of the teaching and learning process [19].YouTube learning media is a messenger component that contains subject matter used by lecturers in the learning process to support the success of the student learning process to be effective and efficient because the process of delivering information is easier, faster and accurate [20].States that self-confidence is a complex and dynamic belief that a person has to achieve the expected goals.
Self-confidence will strengthen the motivation to achieve success, because the higher the confidence in one's own abilities, the stronger the spirit to complete the work.His will to achieve what is the target of the task will also

Figure 1.Research paradigm The design used in this study is a treatment by level 2x2 design.The design of this study is divided into three variables with details of the independent variables formed into two parts, namely the treatment variable using YouTube learning media and the Observation learning method.Meanwhile, selfconfidence as a moderating variable consists of high self-confidence and low self-confidence, while the dependent variable is learning outcomes in the Heavy Equipment Technology course.This research was conducted in Automotive Engineering, Faculty of Engineering, State University of Padang with a sample of 32 students in the experimental group and 32 students in the control group.Samples were taken by cluster sampling technique.Data were collected through validated tests.The data analysis technique used two-way variance test (ANOVA) and Tukey test.The instrument grid is divided into two, namely the non-confidence test instrument grid and the Heavy Equipment Technology learning outcome test instrument grid.
types of variables, namely independent or treatment variables, attribute variables and dependent variables.The independent variables or treatments in this research are the YouTube learning media and the Observation learning method.The moderator variable in this study is high self-confidence and low selfconfidence, while the dependent variable is learning outcomes in the 2019 entry year Heavy Equipment Technology course that students get after studying with the learning process.
be stronger.It means that he also has a strong Volume 6, Number 2, November 2021 ISSN 2528-2611, e-ISSN 2528-2700 commitment to work well, so that the completion of his work goes perfectly [21].

Comparison of learning averages using YouTube and learning the observation method At the time of learning, students' selfconfidence is influenced by campus environmental factors, one of which is the lecturer involved because the lecturer provides motivation, support and reinforcement tostudents.Student confidence is needed so that student activity in class will appear so that the class atmosphere will be conducive, there is feedback between lecturers and students, as well as between students and other students so that it will affect student learning outcomes.The use of YouTube learning media used by lecturers in the learning process to support, motivate students so that the emergence of self-confidence so that it affects student learning outcomes[22].Student learning outcomes can be known through evaluations conducted by lecturers.Student learning outcomes are not only measured by the level of mastery of science, but also attitudes and skills.Assessment of student learning outcomes includes everything that has been learned on
