Animated Video Media Based on Adobe After Effects (AEF) Application: An Empirical Study for Elementary School Students

The development of the world of digitization is so fast that changes in the education sector also have an effect on the growing learning model. This study aims to determine the use of Adobe After Effects (AEF) based animation video media in my living environment material in grade IV in elementary school. The initial stage of media testing was carried out on 3 media experts, 3 material experts, 5 class teachers from five schools in different regions. The number of samples in this study amounted to 132 students. The data were collected using a Likert scale questionnaire 1 to 5. Based on the data obtained, it shows the value of: (1) the average value of the media expert test (89.71%) including the criteria “Very Valid”. (2) the average value of the material expert test is (84.88%) including the criteria “Very Valid” (3) the average product trial feasibility by the teacher is (90.25%) including the criteria “Very Good” and (4) the average result of product testing by students is (91.79%) are categorized as “Very Good”. The conclusion is that animation video media is very good for use in curriculum learning and is able to construct patterns of thought so as to motivate students in learning. For further research, a development model can be carried out.


Introduction
Education is defined as the process of changing the attitudes and behavior of a person or group of people in an effort to mature humans through teaching and training efforts; the process of action and how to educate [1].Education is very needed and very valuable [2]. Corona Virus Disease or COVID-19 was declared a pandemic on March 11, 2020, a disease that is endemic to almost all countries in the world [3]. With the spread of the corona virus, learning carried out in elementary schools also uses online / distance learning through parental guidance [4]. Online learning that is carried out makes teachers need learning media as a means to deliver material attractively.
Learning media can be interpreted as hardware or software tools used in the delivery of material by teachers to students in the learning process. The media is expected to make the learning process more effective and efficient in accordance with the learning objectives [5]. To support the implementation of a fun learning process, it is necessary to provide adequate teaching aids that can provide direct experience to students through practicum or demonstrations conducted by the teacher. [6].Teachers can use any type of audio-visual media that is able to provide clarity on the material being studied [7]. Animated media facilitate students' thinking on the cognitive aspects of the level of remembering and understanding [8]. The ability of teachers is expected to be more skilled and

Methodology 2.1 Participant
This study involved 3 media experts [20], 3 material experts [21]as well as 5 teachers and 132 students. The experts are lecturers at Prof. Muhammadiyah University. Dr. Hamka. Meanwhile, teachers and students come from public schools in Jabodetabek as users of animated video media based on Adobe After Effects.

Instrument and Procedure
This research instrument and procedure is a type of survey research. The instrument used was a survey questionnaire that was filled in online using the google form application [3]. There are four types of questionnaires; first there are 3 other questionnaires media experts, material experts and teachers to assess the appropriateness of instructional media, the second questionnaire is for students. The steps developing animated video media based on Adobe After Effects include the five steps ADDIE model. ADDIE stands for Analysis, Design, Development or Production, Implementation or Delivery and Evaluations [22]. The analysis stage of this research, it involves curriculum analysis, syllabus and analysis of the characteristics of students. At the design stage, prepare the material, make a flow chart and make a storyboard. While the research instrument stage was developed for feasibility assessment of the developed Adobe After Effects-based animated video media. At the development stage, the flowchart, materials, stoybord already made embedded into the media. To develop animated video media based on Adobe After Effects, the main software used is Adobe After Effects, and the supporting software tools used is Adobe Illustrator. At the design and development stage, evaluation is carried out by experts, so that the media being developed receives corrections and input for improvement. At the implementation stage, the animated video media was declared feasible by media experts and material experts, tested on students in five different schools. Furthermore evaluation stage, at the evaluation is carried out at each stage of development by researchers with the help of experts.

Assessment of animated video media based on Adobe After Effcts by experts.
Based on the results of media validity by 3 media experts and 3 material expets. Learning media is stated to be very valid with the input and suggestions given [23]. Data from questionnaires by media experts are presented in Table 1 and questionnaire data by material experts is presented in Table 2.

Language and Writing
Readability of writing. 7 90% Very Good The articulation of language is clear and understandable. 9 Average 90.25% Very Good Based on the results of the assessment by the teacher's in tabel 3, tahat the average ssessments of the animation video media as a whole is 90.25% which is includeed in the very good criteria which indicates that the teacher,s can use animated video media based on Adobe After effects as a lerning media for style and motion material [24].

Assessment of animated video media based on Adobe After Effects by Students.
After the media was validated by media experts, material experts an teachers, the media was tried out on students to find out whether animated video media could be used by students to support their understanding of the style an motion material. [25]. The results of the average percentage un each aspect valued 91.79% can be seen in the Table.4 Strongly agree The following averages is the final results of animated video media based on Adobe After Effects that have been developed based on the assessments and suggestions of experts, teachers and students which can be seen in Table 1-4. The following is the final result of the animated video medi that has been revised by media experts and material experts in Table 5.
