Keywords—augmented reality, interactive models, special abilities, vocational education, digital 4.0 1 Background The development of the world of education continues to experience a substantial evolution. All kinds of learning media began to transform into sophisticated digital media. Various developed countries such as the UK, Germany, France, the United States continue to develop interactive and meaningful learning media [1], [2]. The digi- tal era 4.0 has changed the concept of education so far. In the age of digital literacy, the transformation of electronic learning resources must be the primary emphasis of educa- tional development [3]. However, vocational education to prepare a skilled workforce 188 http://www.i-jim.org https://doi.org/10.3991/ijim.v15i21.24833 mailto:tuwoso.ft@um.ac.id Short Paper—The Innovation of Augmented Reality Learning Media with Interactive Component Model... is not yet fully prepared to face this change. The gap is due to the learning media facilities in higher education institutions that cannot keep up with technological devel- opments in the industry. However, currently, the development of sophisticated learning media is relatively challenging to develop. This is due to the limited knowledge and ability of educators to engineering learning media. The digital learning media devel- oped are too monotonous, such as video models, e-modules, and presentation slides. There are not many learning media that are augmented reality or virtual reality models. On the other hand, success in the learning process is influenced by several factors: teachers, students, media, and environmental factors [4], [5]. Changes caused by digitization 4.0 also change the need for work competencies. Job competencies needed in vocational education are usually called special abilities. Even though the education program 4.0 can be aimed at equipping skilled and superior students with the abilities needed by an industry driven by digital technology [5]–[7]. More research and learning materials need to be developed with AR technology and then implemented in the learning process. To develop AR, the necessary technology and 3D models must be prepared, and the appropriate framework must also be considered. Augmented reality has unique abilities that can affect student learning experiences. The development of AR technology allows researchers to develop and evaluate learning experiences using augmented reality [9], [10]. Innovative learning media is a solution that must be used in learning in vocational education. Industrial augmented reality (IAR) is one of the pillars of the concept of industrial digitization [11]. Augmented Reality (AR) learning media are innovative media to solve problems and challenges in education. This technology has the advan- tage of increasing student interaction and contribution to learning [12]. Augmented Reality (AR) is a digital technology that can display 3D animations of workpieces. Real-world workpieces can be visualized using this digital learning media technology [13]. AR-based digital learning technology benefits can be felt after the availability of resources, lesson planning, and good teacher training [14]. This research aimed to develop augmented reality learning media with 3D models to help vocational students strengthen their unique abilities in the digital 4.0 era. Industry demands are driving the development of cutting-edge technology-based learning media. 2 Method The researchers used to research and development (R&D) methodologies to accom- plish the research objectives, then used quasi-experimental methods to determine the product’s effectiveness. The R&D approach is used to create learning media innovation products, whereas the quasi-experimental approach evaluates learning media innova- tion effectiveness. The stages that the researcher went through are depicted in detail in Figure 1 below. iJIM ‒ Vol. 15, No. 21, 2021 189 Short Paper—The Innovation of Augmented Reality Learning Media with Interactive Component Model...

It was carried out in two classes, namely one control class and one experimental class. The first step is to exam- ine the experimental and control classes’ initial abilities, which will be the focus of the study. Table 3 summarizes the findings of the examination of the two classes’ initial ability tests. Table 3. Analysis of the initial ability test results T-test for Equality of Means T Df Sig.

Table 3 depicts the two classes’ initial ability tests before adopting augmented reality learning media with 3D models. The summary of these results shows a significance value of 0.2733. Based on these findings, there is no significant difference in beginning ability between the two classes. According to these findings, there is no significant difference in starting ability between the two classes. In addition, the final ability test results are examined and are presented in Table 4 below. Table 4. Analysis of the final ability test results T-test for Equality of Means T Df Sig.

This uses the latest learning media, and the control class that does not can be seen in Table 4 above. Based on these results, the significant value is 0.004. This demonstrates that the results of the final ability test of the two classes that are the subject of the study differ significantly. As a result, the most recent learning media items generated in this study are highly effective. 4 Discussion 4.1 The attractiveness of augmented reality learning media with interactive 3D models learning media The study’s development of augmented reality technology has a high level of appeal. This is supported by the results of two validators in vocational education who are instructional media professionals and material professionals. The validation results show that two indicators of innovative media development get the maximum percent- age score, and the results of the validation of vocational materials have two indicators of getting the maximum percentage score. Students’ special abilities correlate with the role of learning technology. If the quality of learning technology is good, the student’s ability will increase. Cutting-edge learning media simulation is a type of innovative learning technology [15]. The innovative AR learning technology products developed have accessibility, attractiveness, and ease of use. AR technology can transform learn- ing experiences in various disciplines, without exception vocational education [16]. Therefore, an excellent digital learning media development design can optimize the benefits of AR technology. AR learning technology becomes a medium for realizing educational goals. The educational goals to be achieved will be realized by selecting designs that attract users. This is, of course, in line with AR learning media technology advancement, which aims to meet learning objectives efficiently. The development of an AR learning tech- nology must focus on the suitability of learning materials with target competencies. Accountability for the ethical design of AR product development in a learning envi- ronment is essential, especially when integrating media into learning content [17]. The 194 http://www.i-jim.org Short Paper—The Innovation of Augmented Reality Learning Media with Interactive Component Model... target competencies that are focused on in this research are students’ unique abilities. One of the unique abilities of students in the digital era 4.0 is the ability to think cre- atively. The use of AR media can provide a real stimulus for improving student skills. The learning material developed has good novelty. In simple terms, AR can be defined as a natural environment that is added to virtual objects [18], [19]. Merging of real and virtual objects is possible with appropriate display technologies, interactivity is pos- sible through specific input devices, and good integration requires effective tracking. This is the main function of educational media as a source of learning. Educational media can replace the function of educators as learning resources because learning resources consist of messages, people, materials, tools, techniques, and the environ- ment that affect student learning outcomes [20], [21]. 4.2 The effectiveness of augmented reality learning media with interactive 3D models learning media As explained above, the development of AR learning media focuses on media and material. This is to ensure that graduates are prepared to meet the unique needs of the industry, which need specialized skills. This learning technology supports student-cen- tered learning. Student-centered learning (SCL) contributes to successful learning [22]. The relevance of AR learning technology realizes the digital era 4.0. Digital transfor- mation is the basis for Industry 4.0 [23], [24]. The increase in students’ special abilities can be improved by improving the quality of digital literacy in students. AR learning technology will give lecturers the flexibility to analyze learning problems for students. So that student learning independence can be realized. Good learning must start with the provision of digital technology-based learning media. The demands of the digital era 4.0 cover at least four main abilities that students must have. This competence encompasses mindsets, working, tools, and living in the world skills [25]. This utilization will be able to improve students’ unique abilities if appropriately done to realize meaningful learning. AR learning is more effective than video learning for learning with complex motor skills [26]. The advantages of AR learning media are easier to access anywhere, has a high level of attractiveness, and saves more time for student learning. Improving students’ unique abilities with digital technology can be optimized with the right pedagogical approach. So that the use of digital learning, apart from being a means of communication and access to information, digital learning technology can be used as an educational or learning tool [27]. Collaborative learning projects have been successfully realized with augmented reality technology [28]. The most recent information distribution method for learning materials is augmented reality (AR). The use of these mediums in teaching aids technical advancement. It is proven that the professional level of students is influenced by the application of AR technology in learning [29]. One of the most straightforward uses of AR in education is to insert it into classroom learning activities. Augmented reality in the classroom can also turn a regular class into something extraordinary for students. We can present examples or simple games made using AR. With interactive visuals, students will more easily absorb the material being taught. 2D and 3D objects in AR provide a broader picture to users. Not limited iJIM ‒ Vol. 15, No. 21, 2021 195 Short Paper—The Innovation of Augmented Reality Learning Media with Interactive Component Model... to the outside, the user will also see the ins and outs of the object deeper [30], [31]. This certainly creates a different perception to him of something he sees from various perspectives. In the modification phase, the most significant classroom and teaching methods are modified to suit the more specific goals of the technology, thus providing new opportunities for learning that are not available through traditional methods. In the modification stage, the teaching and learning process begins to become more effective. 5 Conclusion The development and testing of the effectiveness of the most recent learning media have a conclusion in three main categories. First, the most recent augmented reali- ty-based learning media technology offers much potential. Second, in the digital era, the latest augmented reality-based learning media technology can help vocational students strengthen their specific abilities. Third, the results of validation by media experts, showed that the item level of accessibility accuracy in selecting images, icons, colors, sounds, and 3D models got the highest score (100%). The results of the validation by material experts showed that the item material’s compatibility with the competency objectives and the complete presentation of images, graphics, and videos on certain materials got the highest score (100%). Fourth, the findings of this study can be used as a model for the development of new digital learning technologies with a broader reach and application in the field of education. 6 References [1] A.
