Abstract

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.

Abstract

The purpose of this study was to determine whether there was an effect of waist flexibility, coordination and arm power on the smash of badminton players. The research method used in this research was correlational research. For the research subjects used was badminton athletes from Klub FIK UNJ totaling 30 people. The test instruments used in this study were: 1) to measured waist flexibility used a standing trunk flexion test, 2) to measure coordination used a throw and catch ball test on the wall, 3) to measure arm muscle power used medicine overhead. throwing test, 4) to measure the results of the smash used a smash hit accuracy test. The results showed that: there was an effect between waist flexibility toward smash with a value of tcount = 3.64 and ttable = 1.701, there was an effect between coordination toward smash with a value of tcount = 3.60 and ttable = 1.701, and there was an effect between arm muscle power toward smash with a value of tcount = 4.71 and ttable = 1.701. The conclusion of this study was that the smash of badminton players are influenced by waist flexibility, coordination and arm muscle power. Therefore, the coach must pay attention to the physical component factors that affect the results of badminton players' smash.

Abstract

Penelitian ini bertujuan untuk mengetahui hubungan daya ledak otot lengan dan keseimbangan terhadap kemampuan memukul bola Softball. Penelitian ini dilaksanakan pada bulan Oktober hingga Desember 2023 dengan jumlah populasi pada tim Softball Universitas Negeri Jakarta berjumlah 20 orang. Metode penelitian ini menggunakan metode deskriptif dengan tes dan pengukuran untuk mengukur daya ledak otot lengan dengan menggunakan medicine ball, mengukur balance menggunakan standing balance test, dan untuk kemampuan memukul bola Softball menggunakan fungo batting testt. Teknik pengambilan sampel dilakukan dengan metode total sampling. Teknik analisis data yang digunakan menggunakan rumus korelasi sederhana dan korelasi ganda. Hasil analisis data menunjukkan terdapat hubungan yang berarti antara daya ledak otot lengan dengan kemampuan memukul Softball, dengan koefisien determinasi daya ledak otot lengan dengan kemampuan memukul Softball memberikan sumbangan 6,3%. Komponen kesesimbangan dengan kemampuan memukul Softball memberikan sumbangan 54,1%. Terdapat hubungan yang berarti antara daya ledak otot lengan dan keseimbangan dengan kemampuan memukul Softball yang memberikan sumbangan terhadap kemampuan memukul Softball sebesar 61,1%.

Abstract

This study aims to determine the relationship between hand-eye coordination and confidence in badminton smash shots. The research methods used are an associative quantitative approach, a survey method with test and measurement techniques while the data analysis technique uses a path analysis approach. The study population is beginner athletes at the Gold Badminton Club and Sarwendah Badminton Club. The sampling technique used with total sampling is that the entire population is used as a sample. Based on the results of the data calculation, the value of Fcal = 4.612 was obtained and it was known that the significance value (Sig.) in the F test was 0.041. Because Sig. 0.041 < 0.05, it can be concluded that hand-eye coordination significantly affects the skill of the badminton game. For the calculation of confidence, the value of Fcal = 8.587 was obtained and it was known that the significance value (Sig.) in the F test was 0.007. Because Sig. 0.007 < 0.05, it can be concluded that Confidence (X2) has an effect on the Badminton Game smash hitting skill (Y) or means significant. So it can be concluded that based on the output table, the value of the coefficient or R square is 0.141. This value means that the influence of hand-eye coordination (X1) on the smash stroke skill of the badminton game (Y) is 14.1%, while the rest is influenced by other factors. Meanwhile, based on the output table, the value of the coefficient or R square is 0.235. This value means that the influence of Confidence (X2) on the smash hitting skill of the badminton game (Y) is 23.5% while the rest is influenced by other factors.
