The lantern as a blackboard animation learning medium is very feasible (valid) to be used in learning with an average validation value of 94.87%.


INTRODUCTION
The National Education System is regulated by law. The Law on the National Education System, paragraph 1, states that basic education is the level of education that underlies further education. Based on national education standards, the implementation of education in all regions of Indonesia is required to have the same quality and quality. The implementation of education in the era of using technology 4.0 is required to be learning that motivates students and is innovative in solving problems they face in school [1].
In accordance with Ahmad [2] in Nana [3] there is a shift in the learning process, including from classrooms to infinite places and from paper to paperless. Therefore, the compiled learning modules are made digitally. The digital learning module is a unit of teaching program that is systematically arranged and completely outlined in digital form for learning purposes [4].
The existence of learning media in the form of digital learning videos for students can reduce the burden of carrying more than 1 (one) textbook [5]. Students can study independently easily because the modules are arranged systematically and completely. Students can study in accounting laboratories and in unlimited places with their laptops. The existence of this digital learning module can reduce paper usage so that it will have a good impact on the environment.
The use of the lantern mini server was welcomed by teachers, especially teachers who had difficulty teaching without using media. Lentera is a mini server that functions like a mini PC. The lantern can also function as a web storage medium or as a web server. This lantern is designed using Rasberry pi +. Here are the raspberry pi specifications used: By using a local network with the lantern mini server as the access point. ICT integrated classroom simulation can be carried out well. Students and teachers are connected via their respective smartphone devices. The teacher designs the learning media which is then inserted into the lantern mini server as digital learning content.
The learning system in SMKN 2 Tarusan Pesisir Selatan, majoring in Audio Video Engineering (TAV) uses the teacher as a learning resource center. From the results of interviews with teachers of the assessment system and the provision of material using textbooks and other written-based teaching resources. Teachers are helped after training on the use of mini server lanterns as a learning medium for digital classes both in the teaching and learning process, assignments and assessments. To fill in interesting digital learning content, whiteboard animation was chosen as a medium for delivering theory in the form of videos for independent student learning [6].
Whiteboard animation learning media can help the knowledge of Vocational School 2 Tarusan teachers. 2) the use of learning media increases student interest, attitudes and understanding as well as motivation. Based on the various statements mentioned above, the development of learning media in the form of whiteboard animation needs to be designed to fill the digital learning content of the lentera mini server.

METHOD
Based on the problems previously described, this study will produce a learning media product. According to Sugiyono [7] research and development methods are research methods used to produce a particular product and test the effectiveness of the product. This research procedure adapts the ADDIE development model which consists of five stages which include analysis, design, and evaluation [8].
The ADDIE model consists of 5 components that are interrelated and structured systematically, which means that from the first stage to the fifth stage in its application, it must be systematic and cannot be ordered randomly. These five stages or steps are very simple when compared to other design models. Because it is simple and systematically structured, this design model is easy to understand and apply [9].
The ADDIE development research steps in this study are presented in the form of the chart below: The following are the steps for the ADDIE model development model: a. Analysis The first stage is to analyze the characteristics of students majoring in audio video engineering, the needs of the material to be made into a whiteboard animation video and analyze the needs of the tools or devices used. Primary data is obtained through interviews and secondary data from existing research references. b. Design Create pages in the application. Starting from the front page of the main menu that can be accessed. The page / layout starts the game. Final score page. The entire page is sorted one by one. c. Development Consisting of interactive animation media creation, media validation and media revision. Development starts from media validation and application content. d. Implementation The implementation of this whiteboard animation video was carried out at SMKN 1 Tarusan Pesisir Selatan. One class consists of 25 students and 1 teacher. The teacher uses the computer to guide the students using a whiteboard animation video. e. Evaluation Evaluation is carried out after the program has been implemented, it will look for deficiencies and improve them so that the resulting product is more optimal and suitable for use.

RESULTS AND DISCUSSION
The results obtained are based on the implementation of the development method using the ADDIE model. The following is a complete review of the steps for conducting the research.

Analysis software This interactive whiteboard animation of science learning is intended for young children who are just entering the learning period while playing. Primary data obtained from interviews at Tarusan Pesisir Selatan District Vocational School explained the needs of users of the whiteboard animation application, namely students and teachers of SMKN 2 Tarusan Pesisir Selatan. The material used is to recognize various substances that are harmful and not harmful to the human body. In designing interactive animation, supporting equipment is also needed for the process of making and testing conducive interactive animation learning. The following are the aspects needed in making interactive animation learning [10]. Interface design is done by paying attention to users who use the application so that application users can easily use the buttons and features on the whiteboard animation. Interface design provides information to the user so that it is in line with the objectives to be achieved. Interface design of whiteboard animation starts from: The main menu interface design for a whiteboard animation for a healthy lifestyle a) Design the audio and video engineering material storyline The storyline design to be designed is the psychoacoustic anatomy of the human ear, which is a material that discusses the human ear which is very functional with children audio video techniques. a) Interface Design At the development stage, the implementation of the storyline is applied to vidioscribe to become one complete learning video. Entering text and audio makes the media whiteboard animation more interesting. The narrative will also guide students to better understand the material presented.
