Abstract
Extracurricular participants at SMAN 1 Gending lack three-point shooting skills so that participants are less precise about three-point shooting accuracy. The aim of this research was to improve the three-point shooting ability of male basketball extracurricular participants at SMAN 1 Gending. Through the application of the distributed practice training method, this research is action research in the field of sports which will later be used as material for a coach evaluation program that can improve three-point shooting skills. This research was carried out in 2 cycles, with each cycle holding 3 meetings. A total of 20 male students participating in extracurricular basketball at SMAN 1 Gending were the focus of this research. The three-point shooting test 25 times in 2 minutes is the measuring tool. The final results showed an increase in the percentage of successful three-pointers from 55% to 59% in the first cycle, and increased to 75% in the second cycle. It has been proven that the distributed practice training method is effective in improving the three-point shooting ability of basketball extracurricular participant
Karakteristik Sifat Kimia, Fisis, dan Mekanik Papan Komposit Berbahan Baku Limbah Tulang Daun Kratom
Get PDFPenelitian ini mengkaji potensi limbah tulang daun kratom (Mitragyna speciosa) sebagai bahan pengisi (filler) dalam pembuatan papan komposit. Fokus kajian meliputi evaluasi karakteristik sifat kimia bahan baku serta sifat fisis dan mekanik dari papan komposit yang dihasilkan. Hasil analisis kimia menunjukkan bahwa tulang daun kratom mengandung lignin sebesar 16,83%, holoselulosa 59,65%, α-selulosa 38,60%, hemiselulosa 21,05%, dan zat ekstraktif sebesar 26,39%, yang mengklasifikasikan bahan ini sebagai sumber lignoselulosa dengan kadar lignin rendah dan hemiselulosa sedang. Papan komposit diproduksi menggunakan resin urea-formaldehida sebanyak 16%, kemudian dikempa panas pada suhu 200°C dengan tekanan 25 Pa selama 10 menit. Papan yang dihasilkan memiliki kerapatan sebesar 0,55 g/cm³, kadar air 3,89%, pengembangan tebal 57,07%, keteguhan tarik 0,83 kgf/cm², modulus patah (MOR) sebesar 70,91 kgf/cm², dan modulus elastisitas (MOE) sebesar 9.057,6 kgf/cm². Seluruh parameter memenuhi standar SNI 01-4449-2006, kecuali untuk pengembangan tebal. Hasil pengujian ini menunjukkan bahwa, meskipun kandungan zat ekstraktif yang tinggi dan sifat higroskopisnya menyebabkan ketidakstabilan dimensi, limbah tulang daun kratom tetap memiliki karakteristik yang menjanjikan sebagai bahan baku papan komposit berkelanjutan apabila diberikan perlakuan yang tepat
Karakteristik Daya Serap Bunyi Komposit Akustik Berbahan Pelepah Pisang (Musa paradisiaca) Berdasarkan Variasi Komposisi
Get PDFPenelitian ini mengkaji nilai koefisien absorpsi bunyi dari komposit akustik berpenguat serat pelepah pisang berdasarkan variasi komposisi bahan baku. Variasi komposisi matriks dan filler yang digunakan secara berturut-turut adalah 60:40, 50:50, 40:60, 30:70, dan 20:80. Metode penelitian yang dilakukan dimulai dengan tahap pembuatan papan komposit dengan alat hot press; tahap pembuatan sampel uji yang mengacu pada standar SNI-01-4449-2006 dan ISO 11654; tahap pengujian papan komposit akustik pada kerapatan, kadar air, porositas, internal bonding (IB), dan daya serap bunyi sampel. Hasil penelitian menunjukkan bahwa pengujian fisis papan komposit pada kerapatan, kadar air, porositas telah memenuhi SNI 01-4449-2006. Tetapi pada pengujian mekanis internal bonding (IB) hanya terdapat 1 variasi saja yang memenuhi SNI 01-4449-2006. Komposisi 30:70 (matriks:filler) menghasilkan performa terbaik jika dibandingkan dengan variasi lainnya pada penelitian ini, dengan nilai koefisien absorpsi bunyi (α) sebesar 0,27 pada ketebalan sekitar 1 cm, 0,19 pada ketebalan sekitar 2 cm, dan 0,14 pada ketebalan sekitar 3 cm, dalam rentang frekuensi 1000 Hz hingga 4000 Hz. Oleh karena itu, papan komposit berpenguat serat pelepah pisang ini efektif digunakan sebagai material akustik pada frekuensi 1000 Hz hingga 4000 Hz dengan ketebalan 1 cm - 2 cm dan sesuai dengan ketentuan ISO 11654
Undergraduate Students' Perceptions of Writing Anxiety in English Academic Writing in Taiwan
Get PDFThis study investigates Taiwanese undergraduate students' perceptions of writing anxiety in academic English writing. The goal of the study was to examine anxiety levels and identify the methods students use to cope with them. A mixed-methods approach was employed, using both qualitative interviews and a Writing Anxiety Perception Questionnaire. The questionnaire assessed three forms of anxiety: avoidance behavior, physical anxiety, and cognitive anxiety. The findings revealed that writing anxiety ranged from mild to severe, with physical and cognitive anxiety being the most prevalent. Students reported that the primary causes of their anxiety were physical symptoms such as nervousness and the fear of receiving poor grades. Qualitative interviews identified several coping strategies, including clarifying assignment criteria, breaking tasks into smaller goals, and drawing on prior experiences. Additionally, structured writing techniques such as brainstorming and outlining, along with feedback from peers and teachers, were found to help reduce anxiety and improve writing outcomes. The results emphasize the importance of addressing writing anxiety in educational settings for students to succeed. Educators can support students by teaching effective writing techniques, creating a positive learning environment, and providing regular feedback. Specialized interventions for both local and international students are recommended to further reduce anxiety and improve writing proficiency, ultimately enhancing academic performance.
