Abstract

Purpose of the study: The importance of arm muscle strength and leg muscle explosive power in contributing to volleyball smash ability prompted researchers to analyze their magnitude in relation to student or athlete achievement in volleyball learning, which is part of the physical education curriculum program. Methodology: This type of research is quantitative, using a correlational approach with a quasi-experimental method. The population in this study were volleyball athletes with a sample of 20 athletes. The instruments used in this research were the hanging elbow test, vertical jump test and smash ability test. Meanwhile, this research data analysis technique uses statistical data analysis through linearity and correlation tests. Main Findings: Based on the research results, it was found that arm muscle strength and leg muscle explosive power make a significant contribution and have a big influence on the smash ability of athletes or students. Therefore, these findings require follow-up regarding the development of innovative teaching resources, such as textbooks or monographs, as a step to improve an athlete's or student's smashing ability in the volleyball learning process, thereby increasing students' motivation and learning outcomes. Novelty/Originality of this study: This research provides an in-depth analysis of the athlete's arm muscle strength and leg muscle explosive power on their smash ability by designing a training program and strategy that are more effective and suitable for improving volleyball smash ability.

Abstract

Sendangsari Village, Purworejo Regency, has significant agricultural potential, but its utilization is not optimal due to low digital literacy among farmers and minimal application of modern technology. This condition poses challenges in supporting sustainable agriculture, so technology-based innovation is needed. This study aims to analyze the strengthening of digital literacy in sustainable agriculture through the application of the Internet of Things (IoT) in empowering the Sendangsari Millennial Farmer Community. The method used was a mixed method with a questionnaire instrument, pre-test and post-test, and plant growth measurements in IoT-based and manual fields. The results showed a significant increase in participant understanding, marked by a 17.77% increase in post-test scores from the pre-test score of 70.8. The application of IoT in the experimental field also resulted in more optimal growth of tomato, lettuce, and caisim plants compared to manual methods, and increased the confidence of millennial farmers in adopting technology. This study concluded that agricultural digital literacy can be strengthened through socialization, training, and practice of the application of the Internet of Things (IoT). Village institutional support, expanding internet access, and developing the capacity of young farmers are recommended to accelerate the transformation towards sustainable agriculture.

Abstract

Desa Sendangsari terletak di Kecamatan Bener, Kabupaten Purworejo, Provinsi Jawa Tengah memiliki lahan yang cukup luas, digunakan sebagai lahan sawah seluas 125.000 Ha, lahan perkebunan seluas 25.000 Ha, dan lahan ladang seluas 77.000 Ha. Permasalahan utama yang dihadapi mitra adalah keterbatasan pengetahuan dan keterampilan sumber daya petani, sarana dan prasarana yang belum memadai, serta inkusivitas penerapan pertanian yang belum berkelanjutan. Metode pengabdian yang diterapkan adalah sosialisasi/penyuluhan pentingnya pertanian berkelanjutan, praktek penanaman tanaman obat keluarga dan tanaman buah, praktek pemanfaatan limbah organik dengan membuat pupuk kompos, pupuk organik cair dan ecoenzyme, serta pelatihan pengemasan dan pemasaran produk pertanian menggunakan berbagai platform. Hasil pengabdian menunjukkan bahwa peserta mampu membuat pupuk organik (kompos, pupuk organik cair, dan ecoenzyme), 100% mampu memahami jenis-jenis dan manfaat tanaman TOGA dan tanaman buah, 95,4% peserta memahami tentang jenis-jenis, cara pembuatan dan penggunaan pupuk organik, dan 91,5% peserta memahami strategi pemasaran produk pertanian. Disimpulkan, kegiatan pengabdian mampu mempraktekkan pertanian berkelanjutan melalui pembuatan dan penggunaan pupuk organik untuk tanaman buah dan tanaman obat. Konsep strategi pemasaran juga telah dipahami oleh peserta namun belum sepenuhnya dapat diimplementasikan.
