The objective of this research is to produce an Android-based karate kata scoring board assessment media which aims to assist the jury and administrative team in recapping and assessing karate kata. The research method used a quantitative approach conducted through 5 stages according to ADDIE: the analysis stage, design stage, development stage, implementation stage, and evaluation stage. The research sampling used purposive sampling. The product trials were conducted in two stages: small group trials towards the UNY administration team and large group trials on match referees/judges. The data selection methods and instruments used a questionnaire consisted of several statements and item values to be answered. Steps for developing a scoring board for Android-based karate kata assessment using the ADDIE method, which included 5 steps: Analysis, Design, Development, Implementation and Evaluation stages.

Conclusion: The scoring board for Android-based karate kata assessment from material validation data shows that the content validity results from material experts using the Gregory formula are at 0.71 so it can be concluded that it meets the content validity criteria and is declared valid. The results of the media validation data show that the content validity results from media experts using the Gregory formula are at 0.76 so it can be concluded that it meets the content validity criteria and it is declared valid. The reliability test was conducted with 20 athletes. The results of the reliability test using SPSS 22 for window show that the material results are at 0.656 and the media results are at 0.858 and it is said to be reliable. The small group field trial is at 93% in the very feasible percentage category and the large group is at 94% in the very feasible percentage category. The results of the effectiveness test were conducted on a scoring board for assessing Android-based karate kata using a 10-person match administration team processed by using SPSS-20 to obtain significance scores. (2-tailed) of 0.000. Because the value 0.000 is smaller than < 0.05, Ha is accepted and Ho is rejected. Hence, it can be concluded that there is an average difference between the results of manual data testing using Excel and data input using an Android-based karate kata scoring board, which means that there is an effect of using an Android-based karate kata scoring board in increasing effectiveness and efficiency in processing data on karate kata assessment results.
