PENGARUH PERMAINAN CUP STACKING TERHADAP KETANGKASAN TANGAN (MOTORIK HALUS) SHAREFIT SURABAYA
No full textThe purpose of this research was to analyze the influence of cup stacking games on participants’ fine motor skills, specifically to (1) measure changes in hand speed and hand–eye coordination, (2) evaluate the effectiveness of cup stacking as a fine motor stimulator, and (3) provide practical recommendations for implementing this activity in educational or recreational fitness settings. The study employed an experimental design using a pretest–posttest control group method. A total of 20 participants aged 6–10 years were purposively selected and equally divided into control and experimental groups. Both groups completed a standardized fine motor test before and after the intervention. The experimental group received cup stacking training for three weeks (three sessions per week, 40 minutes each), consisting of progressive coordination and reflex exercises. Data were analyzed using parametric statistical tests after normality and homogeneity assumptions were confirmed. The Paired Samples t-Test showed a significant difference between pretest and posttest scores (t = −5.891, p < 0.001), indicating that cup stacking effectively improved participants’ fine motor abilities. However, the Independent Samples t-Test revealed no significant difference between the control and experimental groups (p = 0.137), suggesting that both groups improved, but not to a statistically distinct degree. These findings confirm that cup stacking has a positive and measurable influence on fine motor enhancement through repeated, coordinated, and visually guided hand movements. The activity stimulates motor learning processes, supports neuromuscular adaptation, and can be implemented as a low-cost and engaging training method in educational or recreational environments. In conclusion, cup stacking represents an innovative and enjoyable approach for fine motor development, encouraging further research with larger samples, longer interventions, and advanced assessments such as biomechanical or neurophysiological analyses to explore its broader impact on motor performance.Tujuan dari penelitian ini adalah untuk menganalisis pengaruh permainan cup stacking terhadap keterampilan motorik halus peserta, khususnya untuk (1) mengukur perubahan kecepatan tangan dan koordinasi tangan-mata, (2) mengevaluasi efektivitas cup stacking sebagai stimulator motorik halus, dan (3) memberikan rekomendasi praktis untuk melaksanakan kegiatan ini dalam pengaturan kebugaran pendidikan atau rekreasi. Studi ini menggunakan desain eksperimental menggunakan metode kelompok kontrol pretest-posttest. Sebanyak 20 peserta berusia 6-10 tahun dipilih secara sengaja dan dibagi rata menjadi kelompok kontrol dan eksperimental. Kedua kelompok menyelesaikan tes motorik halus standar sebelum dan sesudah intervensi. Kelompok eksperimental menerima pelatihan penumpukan cangkir selama tiga minggu (tiga sesi per minggu, masing-masing 40 menit), yang terdiri dari koordinasi progresif dan latihan refleks. Data dianalisis menggunakan uji statistik parametrik setelah asumsi normalitas dan homogenitas dikonfirmasi. Uji t Sampel Berpasangan menunjukkan perbedaan yang signifikan antara skor pretest dan posttest (t = −5.891, p < 0.001), menunjukkan bahwa penumpukan cangkir secara efektif meningkatkan kemampuan motorik halus peserta. Namun, Uji t Sampel Independen tidak mengungkapkan perbedaan yang signifikan antara kelompok kontrol dan eksperimental (p = 0,137), menunjukkan bahwa kedua kelompok membaik, tetapi tidak pada tingkat yang berbeda secara statistik. Temuan ini menegaskan bahwa penumpukan cangkir memiliki pengaruh positif dan terukur pada peningkatan motorik halus melalui gerakan tangan yang berulang, terkoordinasi, dan dipandu secara visual. Kegiatan ini merangsang proses pembelajaran motorik, mendukung adaptasi neuromuskular, dan dapat diimplementasikan sebagai metode pelatihan berbiaya rendah dan menarik di lingkungan pendidikan atau rekreasi. Kesimpulannya, penumpukan cangkir merupakan pendekatan yang inovatif dan menyenangkan untuk perkembangan motorik halus, mendorong penelitian lebih lanjut dengan sampel yang lebih besar, intervensi yang lebih lama, dan penilaian lanjutan seperti analisis biomekanik atau neurofisiologis untuk mengeksplorasi dampaknya yang lebih luas pada kinerja motorik

Get PDFEvaluating lecturers competence in Artificial Intelligence, Technological, Pedagogical, and Content Knowledge (AI-TPACK) and identifying key influencing factors are critical steps toward ensuring effective AI integration. Purpose: This study aims to explore the predictive effect of digital competence on AI-TPACK among sports education lecturers in Indonesia. Materials and methods: A correlational survey design was employed, involving 105 lecturers from Physical Education, Health, and Recreation programs (PJKR) across five teacher education institutions in West Java. Data were collected using two structured scales: AI-TPACK and digital competence. Structural Equation Modeling (SEM) was applied to analyze the relationships between variables. Results: The analysis revealed that while lecturers demonstrated above-average digital competence, their AI-TPACK competence remained below average. A significant positive correlation (r = 0.533) was found between digital competence and AI-TPACK, with digital competence emerging as a primary predictor. These findings suggest that lecturers who are more digitally competent are also more capable of integrating AI into their pedagogical practice. Conclusions: Strengthening digital competence can be a strategic foundation for building AI-related pedagogical skills. Future training programs should integrate both technical and pedagogical components of AI, tailored to the teaching context of physical education lecturers in higher education.Evaluating lecturers' competence in Artificial Intelligence, Technological, Pedagogical, and Content Knowledge (AI-TPACK) and identifying key influencing factors are critical steps toward ensuring effective AI integration.

Outcrop-Scale Investigation of Geological and Soil Physical Controls on Slope Stability in the Semilir Formation
Get PDFLandslides are a major hazard in Indonesia’s volcanic terrains, where highly weathered pyroclastic rocks and intense rainfall frequently trigger slope failures. This study aims to identify geological, geomorphological, and soil physical factors controlling slope stability within the Semilir Formation of Gunungkidul, Yogyakarta. Field observations and laboratory analyses were conducted to compare outcrops affected by translational landslides with adjacent stable slopes. Key parameters include bedding orientation, soil bulk density, plasticity index, and water retention capacity. The results indicate that dip-slope bedding orientations strongly predispose slopes to translational failure, whereas counter-dip structures enhance stability. Landslide-prone slopes exhibit higher bulk density, lower plasticity, and reduced water-holding capacity, which accelerate saturation and decrease cohesion during intense rainfall. In contrast, stable slopes possess higher plasticity and greater water retention, often reinforced by vegetation roots. These findings highlight the combined role of geological structure and soil properties as reliable indicators of landslide susceptibility. The study’s novelty lies in its outcrop-scale comparative approach within a single volcanic formation, providing practical implications for slope management through vegetation reinforcement, improved drainage, and locally calibrated rainfall thresholds.

Get PDFOil palm is a plant that produces palm oil which is widely known as Crude Palm Oil (CPO). Palm oil is refined into crude palm oil (CPO) and palm kernel. Kernel quality parameters include dirt content, water content and percentage of broken kernels. The kernel breaking process uses a Ripple mill machine. The Ripple mill machine is a part that determines the quality of the kernel in production at the kernel station and causes problems when the machine does not work effectively. Common problems faced by companies are frequent sudden machine breakdowns and production results do not meet the specified production criteria. In analyzing machine performance, both production and machine efficiency, the method is carried out by taking samples at the chute sampling point every 2 hours while the machine is operating with different sample weights. The sample is stirred until homogeneous so that whole nuts, broken nuts and broken kernels do not pile up. Then the sample is divided into four or quarts, take two opposite parts and put them in a container. The sample is weighed with a sample weight of 1 kg, pour the sample for analysis by separating whole nuts, broken nuts, and broken kernels. Then weigh the whole nuts and broken nuts, record the weighing results, from the weighing results do calculations using the formula to determine the efficiency of the Ripple mill.Kelapa sawit merupakan tanaman yang menghasilkan minyak kelapa sawit yang dikenal luas dengan sebutan Crude Palm Oil (CPO).
