Abstract

Tujuan penelitian ini untuk mengembangkan model pembelajaran permainan motorik halus anak usia dini. Metode Penelitian yang digunakan menggunakan metode penelitian R & D dari Borg & Gall yang sudah dimodifikasi menjadi 7 langkah. Berdasarkan analisis kebutuhan yang dilakukan oleh peneliti yang berupa pengamatan, wawancara dan penyebaran angket, ditemukan beberapa permasalahan yang dihadapi yaitu kurangnya contoh atau model permainan yang menekankan pada aspek motori halus untuk anak dini. hasil penelitian dari analisis kebutuhan, uji coba produk awal, tinjauan ahli, uji coba kelompok kecil, dan uji coba kelompok besar yang dilakukan maka diperoleh data penelitian. Data tersebut dikumpulkan dan diolah sehingga dihasilkan sebuah produk yaitu model pembelajaran motorik halus anak usia dini. Adapun contoh model permainannya antara adalah: 1.Menghitung menggunakan jari, 2.Bermain dengan gelang karet, 3. Tebak bola warna Memakai telunjuk jari, 4. Melempar bola, 5. Bermain dengan kertas, 6. Membedakan besar kecil, 7. Bermain dengan lilin, 8. Membedakan panjang pendek, 9. Membedakan bentuk benda, 10. Pesan berantai, 11. Pengenalan huruf, 12. Mencocokkan gambar dengan angka.13. Permainan Dadu angka. Hasil dari uji kecil dan uji besar adalah model layak dan dapat digunakan dengan baik.

Abstract

This study aimed to determine the effect of Plyometric Exercise on improving forehand in pickleball, focusing on the age of 15-18 years. The research conducted was quantitative method with quasi-experiment with pre-test and post-test non-equivalent to control the group design. The respondents of this study were 40 pickleball athletes aged 15–18 years. They were divided into two groups, of which 20 respondents were in the experimental group. While the control subjects numbered 20 people. The research instrument used a forehand test on pickleball. The data was analyzed with the SPSS 26 application. The results of this study showed that the value of t = 41.68, df = 20 and its significance (2 tailed) or p-value = 0.000 < 0.05. Thus the descriptive statistical results with 20 experimental subjects showed an average of 18.95, and after they were given treatment, the post-test results showed a mean of 35.05. This shows that descriptively obtained differences before and after treatment. Thus, the descriptive statistical results for the 20 control subjects were an average of 18.20, and after treatment the average post-test result was 22.21. This shows that descriptively obtained differences before and after being given treatment. Therefore, it can be ascertained that this plyometric exercise is effective in increasing the topspin groundstroke ability of junior tennis athletes aged 15-18 years.

Abstract

Plastic waste pyrolysis requires catalysts that are thermally stable, accessible, and economically viable. This study synthesizes and characterizes a biomass-based catalytic material derived from hibiscus flower powder and activated Ulin wood carbon. Hibiscus petals were dried under sunlight for 6 h, oven-dried at 55 °C for 1 h, ground, and sieved to 200 mesh. Ulin wood carbon was reduced by high-energy milling, sieved to 200 mesh, activated in 3 M NaOH using 8 g carbon for 12 h, washed to pH 6–7, and dried at 105 °C for 8 h. UV–Vis analysis showed that hibiscus powder contained 676.62 mg EQ/100 g flavonoids, 2305.06 mg GAE/100 g phenols, 369.69 ppm antioxidant activity, and 122.40 ppm anthocyanins. Activated Ulin carbon contained 166.28 mg EQ/100 g flavonoids, 32.04 mg GAE/100 g phenols, 0 ppm antioxidant activity, and 0.54 ppm anthocyanins. Thermal, morphological, functional group, and crystallinity analyses were conducted using TGA-DTA, SEM, FTIR, and XRD. The results indicate that hibiscus contributes oxygenated bioactive compounds, whereas activated Ulin carbon provides a carbonaceous support structure. The combined characteristics suggest potential use as a sustainable catalyst precursor for plastic waste pyrolysis.
