MAKING SERVICE LEVEL MEASURING EQUIPMENT (SERVICE DETECTOR) IN BADMINTON SPORTS

This study aims to determine how to manufacture a service height measuring device in badminton. The research method used in this research was the Sugiyono model of research and development (R & D) with 5 stages from the nee analysis until field test. The research subjects for the tool trial were 25 referees and 50 men's doubles players who competed using a service height measuring device in badminton. The validation test used in this study is to use the expert justification test which consists of 1 expert lecturer in badminton and 2 referees who have BA certified. After the expert validation test was carried out, then the tool was tested and distributed a questionnaire about the attractiveness and convenience of the service level measuring device at the badminton branch. The result of this research is that measuring service stroke height using ultrasonic sensors is suitable for use in badminton matches to assist service judges in making decisions whether the service stroke is a fault or not. And based on the results of field trials, shows that measuring service stroke height using ultrasonic sensors is attractive and easy to use. The suggestion for this research is to find a tool that is more sensitive to distance and human motion or by using an application

Kata Kunci: Frekuensi Langkah, Panjang Tungkai, Lari 60 Meter ABSTRACT  The purpose of this study was to determine the relationship between step frequency and 60 meter running results, the relationship between leg length and 60 meter running results, and the relationship between step frequency and leg length with 60 meter run results for the 2018 Faculty of Sport Sciences Students. This research was conducted at East Jakarta Velodrome Athletic Stadium. The method used is descriptive quantitative by using correlation studies. The sample used amounted to 30 people, with a sampling technique that is purposive sampling from the existing population of 2018 Faculty of Sport Sciences Students. The relationship of leg length to the 60 meter running result is expressed in the regression equation Y = 43.29 + 0.13 X₁, with the correlation coefficient y ry〗 _1 = 0.134. In the process of testing the significance of the correlation coefficient found t = 0.715 <t table = 1.701 thus the correlation coefficient is 0.134 is not significant. The relationship of leg muscle explosive power to the 60 meter running results is expressed in the regression equation Y = 18.34 + 0.63 X2, with a correlation coefficient y ry〗 _2 = 0.633. In the process of testing the significance of the correlation coefficient found tcount = 4.328> ttable = 1.701 thus the correlation coefficient is 0.633 significant. The relationship between stride frequency and leg length together with the 60 meter run result is expressed in the regression equation Y = 7.5 + 0.20 X₁ + 0.65 X₂ with a correlation coefficient y ry〗 _ (1-2) = 0.915. In the process of testing the significance of the correlation coefficient found Fcount = 70.29> Ftable = 3.35 which indicates that the null hypothesis (Ho) is rejected and the alternative hypothesis (H1) is accepted. Then it can be concluded that there is a significant relationship between the frequency of steps and leg length together with the 60 meter running results of the 2018 faculty of sports students.  Keywords: Step Frequency, Leg Length, Running 60 Meter
