This study aims to determine the effect of auxiliary media on the hitting ability of the tennis game. The research method used is an experimental method, namely using a pre-experimental design experimental design. For a more specific experimental research design, the author uses a one-group pretest-posttest research model. The population in this study were third-grade students of SD Negeri 1 Jambi which consisted of 1 class totalling 31 students. The sample in this study were all third-grade students at the 1jambi State Elementary School, totalling 31 students who were designated as all samples because the number of samples or subjects was less than 100 people, therefore the sampling used the total sampling technique, which included all members of the population as research sample. Based on the results of the research, the count value is 5,208 by looking at the statistical table where the degrees of freedom db=(N-1) are 31-1=30 and at the 5% significance level, the t-table value is 2,042. Thus, it can be concluded that the value of t-test > t-table or 14,667 > 2,042, meaning that the hypothesis is accepted that there is an effect of using auxiliary media on the ability to play tennis in third-grade students of SD Negeri 1 Jambi. The percentage increase is 34.9%.
<p class="0keywords">Blindness is a condition where the senses of vision are not functioning (low vision) or overall (total blindness). Persons with visual impairments are who can enjoy swimming with the help of sensors. The aim of the study was to create aids for sensor-based blind visual swimming that can be used during swimming exercises. The method used is a qualitative approach, the main data obtained through observation, questionnaires, interviews, and documentation and procedures of research and development used is the Borg and Gall model. This study is expected to contribute to blind swimming aids material products which are effectively used for swimming exercise skills. This study concluded that the product development sensor based blind learning swimming aids can be used for motion skills training for blind swimming athletes.</p>
Children aged 5 – 14 years Fitness level profile in Jakarta Timur, this research aims to determine the extent to which fitness level children age range 5 till 14 years old in Jakarta Timur. This research using a test and non test techniques with the survey method. A collection for the sample using a proportionate stratified random sampling techniques. As many as 121 children as sample.
