Abstract

Penelitian ini merupakan penelitian deskriptif kuantitatif yang bertujuan untuk mengetahui pengaruh screen time terhadap motivasi belajar mahasiswa. Populasi dalam penelitian ini adalah mahasiswa program studi pendidikan jasmani, kesehatan, dan rekreasi Universitas Negeri Makassar. Sampel dalam penelitian ini berjumlah 45 orang mahasiswa yang ditentukan dengann Teknik random sampling. Teknik pengumpulan data dilakukan dengan menggunakan kuesioner skala likert yang terdiri dari masing-masing 20 nomor soal mengenai screen time dan motivasi belajar mahasiswa. Adapun nilai Cronbach alpha kuesioner screen time sebesar 0,950 dan nilai Cronbach alpha kuesioner motivasi belajar mahasiswa sebesar 0,957. Sehingga dapat dikatakan kedua kuesioner layak untuk digunakan. Sedangkan teknik analisis data dilakukan dengan menggunakan uji regresi. Berdasarkan hasil uji hipotesis dengan menggunakan uji regresi sederhana pada tabel di atas, diketahui nilai Sig. sebesar 0,000 atau < 0,05 sehingga dapat dsimipulkan bahwa terdapat pengaruh yang signifikan antara screen time terhadap motivasi belajar mahasiswa.

Abstract

Virtual Reality (VR) technology has grown rapidly and is increasingly applied in sports training, including basketball. This study aims to systematically review the effectiveness of virtual reality as a basketball shooting training method. The method used is a systematic literature review (SLR) following PRISMA guidelines. Searches were conducted through Google Scholar, PubMed, Scopus, and SINTA databases with a publication range of 2014–2024. Of 348 articles identified, 28 articles met the inclusion criteria and were analyzed through narrative synthesis. Risk of bias assessment using JBI Critical Appraisal Tools showed that 64.3% of studies had high performance bias due to difficulties in blinding, a common limitation in VR training research. The findings indicate that VR-based basketball shooting training is effective in improving shooting accuracy (average improvement of 24.1% vs. 11.8% conventional), spatial perception, and athlete confidence. VR allows athletes to practice in a safe, repetitive, and measurable simulation environment through mechanisms of augmented real-time feedback, immersive mental rehearsal, and programmed variability of practice. However, limitations include high implementation costs (USD 3,000–50,000), cybersickness risks (50% of studies), and lack of real haptic feedback. The novelty of this review lies in its simultaneous analysis of neuromotor mechanisms and contextual implementation challenges in developing countries. This review recommends integrating VR as a supplement (30–40% of training time) to conventional training to maximize overall basketball shooting training effectiveness

Abstract

The forehand groundstroke is one of the fundamental techniques in tennis that requires complex coordination of the musculoskeletal system. This study aims to systematically analyze the biomechanics of forehand groundstroke technique, including movement phases, segmental body contribution, racket velocity, racket-face angle at impact, and its implications for performance improvement and injury prevention. The research method used a systematic literature review approach by analyzing peer-reviewed journals, textbooks, and relevant academic sources related to tennis biomechanics. The results of the review show that the forehand groundstroke consists of five main phases: initiation, preparation, acceleration, impact, and follow-through. Quantitative findings indicate that racket velocity reaches its peak during the impact phase, with professional players producing racket speeds of approximately 25–35 m/s. Stroke power is generated through sequential segmental contribution involving the lower limbs, trunk, shoulder, upper arm, forearm, and wrist. Kinematic analysis also shows that torso rotation and shoulder external rotation play important roles in increasing racket speed and stroke effectiveness. In addition, the racket-face angle at impact significantly influences ball direction, accuracy, and control. This study concludes that a comprehensive understanding of forehand groundstroke biomechanics can help coaches and athletes optimize technique, improve stroke performance, and reduce the risk of injury. The findings provide practical recommendations for developing more effective tennis training programs based on biomechanical principles
