Abstract

Kesiapan mental merupakan komponen kunci performa atlet, khususnya bagi atlet penyandang disabilitas yang menghadapi tekanan kompetisi sekaligus tantangan psikososial. Namun demikian, pelatih di National Paralympic Committee (NPC) Kota Medan belum secara sistematis menyusun program latihan mental maupun mengintegrasikannya ke dalam jadwal latihan rutin. Kegiatan pengabdian kepada masyarakat ini bertujuan mendampingi pelatih dalam menyusun program latihan mental terunifikasi melalui workshop pelatihan, pendampingan lapangan, dan instrumen evaluasi. Metode pelaksanaan terdiri atas enam tahapan: sosialisasi, analisis kebutuhan, workshop latihan mental, penyusunan program terunifikasi, pendampingan implementasi lapangan, dan penyusunan strategi keberlanjutan. Kegiatan dihadiri 13 pelatih aktif pada tanggal 14 Maret 2026. Hasil menunjukkan bahwa 84,6% pelatih mengalami peningkatan pengetahuan konsep latihan mental secara signifikan dan 84,6% mampu menyusun program latihan terunifikasi yang terstruktur. Modul latihan mental terunifikasi yang dihasilkan mencakup teknik relaksasi, visualisasi, goal setting, dan self-talk. Kegiatan ini berhasil meningkatkan kompetensi pelatih serta menghasilkan panduan latihan mental praktis bagi pelatih NPC Kota Medan.

Abstract

Study purpose. Success in tennis is largely determined by the mastery of correct fundamental techniques from an early stage. Without biomechanically sound and efficient basic techniques, students will find it difficult to develop advanced game tactics. Field observations indicate that students' skill levels remain highly varied and tend to fall within the low-to-moderate categories. The use of the International Tennis Number (ITN) standard is highly relevant as it is an objective international rating system designed to measure a player's accuracy, depth, and power. This study aims to analyze the fundamental tennis technical skills of Sports Coaching Education (PKO) students at University Negeri Medan based on the International Tennis Number (ITN) standards. Materials and methods. This research employs a quantitative descriptive design. The method used was a survey involving tests and measurements. The research subjects consisted of 126 respondents. The instrument utilized was the ITN On-Court Assessment, with data analyzed using descriptive statistics. Results. The results show that the majority of respondents (97.6%) possess basic tennis technical skills at a beginner level, with the most frequent classification being ITN Level 8 (46.8%). Half of the respondents (50%) demonstrated "poor" proficiency in groundstroke depth. Regarding groundstroke accuracy, most participants fell into the "very poor" category (57.9%). Respondents generally exhibited "poor" ability in both volley depth (61.1%) and service competence (62.7%). In contrast, the mobility level was predominantly categorized as "moderate" (42.9%). Conlusion. It is recommended that students engage in independent practice outside of lecture hours. Furthermore, the International Tennis Number (ITN) instrument should be implemented as a course completion standard or a prerequisite for students.

Abstract

This study examined whether visual media could improve university students’ sepak sila skills during sepak takraw instruction. A quantitative quasi-experimental approach was applied using a Nonequivalent Control Group Design. The participants were 40 students enrolled in a sepak takraw course who were selected purposively and assigned to an experimental group or a conventional-learning group. Skill performance was assessed with a one-minute sepak sila test. The data were processed using descriptive statistics, normality and homogeneity tests, paired samples t-tests, and an independent samples t-test. The experimental group improved from a mean score of 17.60 at pre-test to 25.50 at post-test, whereas the conventional group increased from 15.85 to 21.50. The between-group comparison produced p = 0.027, below the 0.05 significance level. These findings indicate that visual-media-supported instruction produced better sepak sila outcomes than the conventional approach used as the control condition.
