Introduction
Education in Indonesia currently uses the 2013 curriculum. The learning is a student-centered approach, so that the teachers s a facilitator. The teachers are required to be able to choose and use the media which suitable with their needs. One example is through a game.
Game as a one of the learning media has often been used, it is proven by the number of studies that examine the use of game as media in learning, for example, card games [1] which said that learning using cards has many benefits than Traditional learning (lectures), besides being fun, card games can also be played from middle level of school until postgraduate level. Used game as a media to attract students' interest in learning [2][3]. In physics subject of vocational school, there is one of the main subjects in grade X namely static fluid. In static fluid, there are concepts and formulas that must be understood and memorized. Inevitably, the material of static fluid is not only learned the theory, but also practice what they do consciously or not is sometimes related to static fluid. The lack of attractive learning media greatly affects the students' interest and learning outcomes, especially for vocational students, because what is needed here is a fun learning without leaving the purpose of learning.
To help students understand the concepts and formulas of static fluid material in ease and fun way, the researchers chose Yu Gi Oh Physics Smart Card (YOPSA) as the learning media. The cards come from Japan, it is must be played with the right strategy, so it can trigger student motivation in learning. So far, learning using the YOPSA has not been implemented at SMK Negeri 1 Semarang. Another advantages of the YOPSA are easy to play, compact and easy to carry anywhere. The lack of this media 2 is easy to be lost because the card size is small, and it easily broken like other cards but can be anticipated by laminated the card.
Based on the background of the problem above, a research was carried out on the development of YOPSA as a learning media for physics on Static Fluid material to increase the interest and learning outcomes of grade X students of SMK Negeri 1 Semarang. The objectives of this study are: (1) to produce learning media based on physics smart cards that are suitable to increase students' interest and learning outcomes of grade X SMK Negeri 1 Semarang in static fluid material, (2) to investigate the increase of the interest in learning physics of students who take part in learning with YOPSA, (3) to know the increase of physics learning outcomes for students who take learning with learning media based on YOPSA.

Methods
