Abstract

This study aimed to examine the direct and indirect effects of arm muscle strength, hand–eye coordination, and concentration on underhand passing performance in junior volleyball athletes. A quantitative approach with path analysis was applied involving 30 male athletes from a school volleyball team using total sampling. Arm muscle strength was measured using the push-up test, hand–eye coordination using the wall toss test, concentration using the concentration grid test, and passing performance using a standardized underhand passing test. The results showed that arm muscle strength (β = 0.548), hand–eye coordination (β = 0.376), and concentration (β = 0.177) had significant direct effects on passing performance (p < 0.05). Indirect effects through concentration were also identified, although relatively small. The model explained 90.4% of the variance in passing performance. These findings indicate that underhand passing is influenced by physical, motor, and cognitive factors, highlighting the importance of integrated training approaches in volleyball development.

Abstract

Participation in school-based sports and extracurricular activities among female students remains relatively low and is often influenced by social support and internal motivational factors. This study examined the influence of parental and peer support on female students' interest in engaging in school-based volleyball extracurricular activities, with intrinsic motivation as a potential mediating variable. A quantitative correlational design using path analysis was employed. The participants were female students actively involved in volleyball extracurricular programs at a public junior high school in Padang (SMP Negeri 41 Padang). Data were collected using validated and reliable Likert-scale questionnaires. The results showed that parental support (β = 0.42, p < 0.001) and peer support (β = 0.36, p = 0.002) significantly predicted intrinsic motivation, which, in turn, significantly predicted students' interest in participating in volleyball (β = 0.51, p < 0.001). Intrinsic motivation was suggested to function as a mediating variable, indicating that social support influences students' interest both directly and indirectly. Parental support, peer support, and intrinsic motivation jointly accounted for 62.5% of the variance in students' interest, while other factors influenced the remaining 37.5%. These findings highlight the importance of social support and intrinsic motivation in promoting sustained participation in school-based sports and extracurricular activities.

Abstract

PT Putra Muba Coal merupakan perusahaan yang bergerak pada bidang pertambangan batubara, Awal mula berdirinya pada tanggal 2009 dan terletak di desa B2 Mekar Jadi, Kecamatan Sungai Lilin, Kabupaten Musi Banyuasin, provinsi Sumatra Selatan. Kegiatan penambangan pada PT PMC ini dilakukan dengan metode penambangan terbuka (surface mining) dimana metode ini di cirikan lokasi penambangan nya berhubungan langsung dengan udara luar. Salah satu masalah di tambang adalah air yang terdapat di front penambangan jika tidak diatasi dengan serius dapat mengganggu aktivitas penambangan bahkan dapat menyebabkan masalah yang fatal yaitu berhentinya produksi. Tujuan tugas akhir ini adalah untuk mengetahui jumlah debit air yang di pompa dan   mengetahui berapa banyak pompa yang dibutuhkan. Metode pengambilan data berupa studi litelatur, studi lapangan dan pengambilan data berupa data primer (jumlah pompa, debit air dan elevasi air, serta ukuran pipa), serta data sekunder (luas catchment area, curah hujan, spesifikasi pompa dan peta lokasi tambang). Hasil kajian di lapangan didapatkan hasil   dengan jam kerja pompa  sebesar 22 jam/hari dimana sisa air yang ada pada sump 205.972,331464 m3. Dan total debit air yang masuk ke sump  sebesar 185.062,99392 m3/bulan  dan debit pompa aktual adalah sebesar 99,275491 m3/jam dan secara teratur pompa akan bekerja selama 28 hari dalan sebulan dengan debit yang dihasilkan 61.153,702456 m3/bulan, maka dibutuhkan 3 unit pompa jika di anggap hujan setiap hari.
