Moreover, physical education which is carried out through jurus tunggal tangan kosong activity as part of the pencak silat movement is very saturating if studied conventionally

Purpose: This study was to get the effectiveness of interactive multimedia using jurus tunggal tangan kosong that it supported physical education.

Methods: The method of study used an experimental approach using one-group pretest-posttest design experimental. A one-group pretest-posttest design is a research method used to determine the behaviour of a group by giving the effect of treatment on the sample.

Results: The result of the N-gain score shows that the N-gain score means for the experimental class is 93.75% and is included in the "high" category, with a minimum score of 72.92% and a maximum N-gain score of 100%. Meanwhile, the N-gain score for the control class was 66.67% and is included in the "medium" category, with a minimum score of 20.83% and a maximum N-gain score of 100%. Thus, it can be concluded that jurus tunggal tangan kosong moves using interactive multimedia has a positive effect on students in physical activity and is more meaningful than learning that is not supported by the use of technology such as multimedia.

Conclusion: The use of interactive multimedia learning contributes to jurus tunggal tangan kosong learning activities, among others, the presentation of teaching material becomes more attractive, learning activities are more interesting, learning activities can be more interactive, the time needed in learning is more effective, the quality of learning can be improved, learning can be done anytime and anywhere as you wish
