that, learning resource of environment consist museum, garden, and other kind of area. Thus, the conclusion of these is that learning resource is everything which can support learning process.
Learning process need supported by adequate learning resource. In line with the research of Hadiapurwa et al. (2021), it shows that the developing of learning resource is need to be conformable with the growth of modern technology. This is in line with the growth of technology and science that has enhance evolution in many kinds of sectors include education, so that the aplication of technology in learning process is needed to optimalized (Malina et al., 2021). Moreover, optimalizing the using of technology in learning also in line with the needed of 21 st century skills which is has encourage education sector for upgrading the using of learning media based on technology in learning process (Muzayyanah et al., 2022). Technology application optiimalization as a learning media can enhance study motivation and the understanding of student towards physics material, and one of them is by optimalize multimedia application. Anas (2019) shows that multimedia is learning resource which is include various kind of media for sending information or message to user based on it's puspose and function. On the digital covered multimedia, the multimedia arrange in such a way in order to interesting and motivate user for studying. The components included in multimedia is text, image, video, animation, and audio. Multimedia has some advantages which could contribute to encourage learning proses, these are (1) resolving the limitation of verbalism; (2) resolving the difference and limitation of student capacity; (3) enhancing student learning interest; (4) enhancing curiosity of the student; also (5) flexible towards time and space (Santhalia & Sampebatu, 2020). Thus, the using of multimedia is potencial to use for the learning of an abstract physics, and one of them is Whiteboard Animation.
Whiteboard Animation is a video that explain a material or theory by drawing process on the whiteboard. The drawing process is synchronized towards the audio of contents material teller directly and clearly (Anggraini et al., 2018). Ki'i et al. (2022) realeved that the view of the Whiteboard Animation consist explaination of material in teks of picture form which are drawn or written by the movement of animation, so that the material is explained become more interesting and enhance student learning motivation. Learning by using Whiteboard Animation is potential to give simplicity of understanding learning material for student. Therefore, the using of Whiteboard Animation multimedia on physics learning is potential to enhance the understanding and motivation of student effectively. Based on the research'es result of Alhidayatuddiniyah (2021) about the development of learning media based on Whiteboard Animation on Coulomb's Law material, obtained that media validity by media expert earned about 88,5% (valid). This is in line with the research'es result of Anggraini et al. (2020) about the development of Whiteboard Animation multimedia on energy and work material, which is acquired high feasibility scor and practical. Consenquently, developing Whiteboard Animation multimedia also potential to enhance student learning motivation on other physics material, one of them is impulse and momentum.
Impulse and momentum is one of physics learning that have many relation with daily life (Yuberti et al., 2019). Momentum learn about tendency of an object to move by constant velocity. The change of momentum can be effected by outsite force which is work at a certain time and called impulse. Impulse and momentum is one of basic concept of physics learning (Rosa et al., 2018). However, student tend have misconception on impulse and momentum material (Putranta & Supahar, 2019). This is caused by reasoning of impulse and momentum as one of highly difficult physics learning material and have abstract property. Consenquently, the abstract property of impulse and momentum need a clearly visualization of concept. The inferior visualization will inflict student difficult to understand the material and also conduce negative effect towards student learning motivation (Triyani et al., 2019). Accordingly, developing multimedia based on Whiteboard Animation on impulse and momentum material is needed for infesting concept visualization explanation needs directly and interestingly, so that the student learning motivation also become enhanced. Learning motivation will conduce enhanching of student learning outcomes.
Based on observation and literatures review, the development of learning multimedia by using Whiteboard Animation to explain impulse and momentum material have not been found. Whereas, the using of Whiteboard Animation multimedia is potential to enhance student learning motiation in Ten'th Grade Senior High School. Therefore, this research aims to develop learning multimedia based on Whiteboard Animation on impulse and momentum material, also to describe the feasibility and practicality of product towards student learning motivation.
