Abstract

Penelitian ini dilakukan untuk mengetahui keterkaitan antara kemampuan daya ledak otot tungkai dengan keterampilan melakukan tendangan momtong dollyo chagi pada atlet Taekwondo Dojang PU Sumbar. Penelitian menggunakan pendekatan kuantitatif dengan metode korelasional. Populasi penelitian terdiri atas 58 atlet taekwondo Dojang PU Sumbar. Pengambilan sampel memakai teknik purposive sampling dengan beberapa kriteria, yaitu atlet aktif berlatih, berada pada usia remaja, dan mampu melakukan tendangan momtong dollyo chagi dengan baik. Instrumen yang digunakan meliputi tes standing broad jump untuk mengukur daya ledak otot tungkai dan tes tendangan momtong dollyo chagi selama 20 detik untuk mengetahui kemampuan tendangan. Sampel penelitian berjumlah 20 atlet putra kategori junior dan senior. Data dianalisis menggunakan teknik korelasi. Hasil penelitian memperlihatkan adanya hubungan yang berarti antara daya ledak otot tungkai dengan kemampuan tendangan momtong dollyo chagi pada atlet Taekwondo Dojang PU Sumbar. Hasil penelitian menunjukkan bahwa daya ledak otot tungkai memiliki hubungan yang signifikan dengan kemampuan tendangan momtong dollyo chagi pada atlet taekwondo Dojang PU Sumbar, yang ditunjukkan oleh nilai thitung sebesar 0,421 pada taraf signifikansi α = 0,05, sehingga hipotesis nol (Ho) ditolak dan hipotesis alternatif (Ha) diterima.

Abstract

Study purpose. This study aimed to develop a valid, practical, and effective Canva-based interactive learning media for Pencak Silat instruction in fifth-grade Physical Education, Sports, and Health (PJOK) at elementary schools in Padang Gelugur District, Pasaman Regency, in response to the low cognitive learning outcomes observed, where 70% of students failed to meet the Minimum Learning Objective Achievement Criteria (KKTP). Materials and methods. The study employed a Research and Development (R&D) approach guided by the ADDIE model, integrated with a quasi-experimental non-equivalent control group pre-test/post-test design. Both classes implemented Problem-Based Learning (PBL) as the shared instructional model, in which the experimental class (SDN 08 Makmur, n=22) used Canva-based media, while the control class (SDN 15 Sontang, n=17) used standard textbooks. Data were analyzed using Jamovi 2.3 through normality tests, homogeneity tests, paired-samples t-tests, N-Gain calculations, independent-samples t-tests, and Cohen's d effect size. Results. Expert validation yielded an overall mean of 90.67% classified as very valid, instrument reliability KR-20 = 0.81, and practicality of 96.00% from the teacher and 91.42% from students, both classified as very practical. The experimental class achieved a mean N-Gain of 0.67 compared to 0.52 in the control class, with a statistically significant difference (t=2.11, df=37, p=0.042) and a pedagogically meaningful medium effect size (Cohen's d=0.68). Conlusions. The Canva-based media was found to be valid, practical, and significantly more effective than standard textbooks within a PBL framework, and constitutes the first scientifically validated Canva-based media developed specifically for Pencak Silat instruction under the Merdeka Curriculum Phase C at the elementary school level.

Abstract

This study aimed to examine the effectiveness of plyometric training in improving Yeop Chagi kicking skills among cadet and junior athletes of JTC Taekwondo Dojang who were preparing to compete in The Arena of Maestro Taekwondo Championship 2026. Plyometric training is widely recognized as an effective method for enhancing explosive power, speed, and sport-specific performance, particularly in Taekwondo. This study employed a quasi-experimental method using a one-group pretest–posttest design. The participants consisted of 20 cadet and junior athletes selected through purposive sampling from a population of 48 athletes. The intervention consisted of 16 plyometric training sessions conducted during the athletes’ championship preparation period. Data were collected using a Yeop Chagi kicking skill test and analyzed using descriptive statistics and N-Gain analysis. The results demonstrated a significant improvement in kicking performance following the intervention. The mean pretest score increased from 15.6 to 21.2 in the posttest. Furthermore, the N-Gain score of 0.57 indicated a moderate level of improvement, confirming the effectiveness of the training program. Statistical analysis at a significance level of α = 0.05 showed that the null hypothesis (H₀) was rejected and the alternative hypothesis (Hₐ) was accepted. These findings suggest that plyometric training is moderately effective in enhancing Yeop Chagi kicking skills among cadet and junior Taekwondo athletes. Improved kicking performance may contribute positively to competitive readiness and athletic achievement during championship participation. Future studies are recommended to employ a control group design and investigate the long-term effects of plyometric training on various Taekwondo performance indicators.
