ANALYSIS OF TECHNOLOGY UTILIZATION TO MEASURE THE THROW DISTANCE OF THE BALL ON HAMMER THROW

The focus of the problem in this study is how to use a
digital distance meter instrument and how it works in measuring the distance from falling to the ball. This study aims to find out how the digital distance metre measuring instrument works in measuring the distance of a hammer throw. This study uses the Research and Development method. The place to make a digital distance metre tool was conducted at the State Vocational School of Patumbak for 6 weeks. Furthermore, the implementation of the tools and data collection would be carried out at the Medan State University Stadium for 30 days; the trial would be carried out 1-2 times a week. Subjects in this study were 4 athletes from the student education and training centre athletes and 2 from the North Sumatera Gold Programme at Medan State University, for a small group trial of 3 athletes and a trial of a large group of 6 athletes. A data collection technique to obtain the data needed in this study which was then analyzed, was by a literature study, functional test, and measurement error test. Data analysis techniques used were data from the results of questionnaires classified into two groups of data, namely qualitative and quantitative data. Qualitative data was obtained through expert validation activities and trial activities in the form of input,
responses and criticism and suggestions. While quantitative data in the form of difference comparisons, collected through field trials, were analyzed with descriptive quantitative analysis. To find out whether there were differences between tools and meters in small group trials and large groups used t-test analysis with a significance level of 5%.
