Abstract

Penelitian ini bertujuan untuk mengkaji keterkaitan antara koordinasi mata tangan dengan kualitas passing atas bola voli. Metode yang digunakan adalah pendekatan kuantitatif dengan desain korelasional. Seluruh populasi dalam penelitian ini terdiri atas 30 siswa laki-laki yang aktif dalam ekstrakurikuler bola voli, dan seluruhnya dijadikan sampel melalui teknik total sampling. Untuk mengukur variabel yang diteliti, digunakan dua jenis tes, yaitu tes lempar-tangkap bola untuk menilai koordinasi mata tangan dan tes passing atas untuk mengukur kemampuan passing. Pengolahan dan analisis data dilakukan menggunakan program SPSS versi 21, dengan fokus pada penghitungan korelasi. Hasil analisis statistik menunjukkan adanya korelasi yang signifikan antara koordinasi mata tangan dan kemampuan passing atas, dengan nilai koefisien korelasi (r) sebesar 0,797 dan nilai signifikansi sebesar 0,000, yang berarti lebih kecil dari batas α = 0,05. Selain itu, nilai koefisien determinasi (r²) mencapai 0,635 atau 63,5%, yang mengindikasikan bahwa variabel koordinasi mata tangan memberikan kontribusi sebesar 63,5% terhadap variasi kemampuan passing atas.

Abstract

Rilau Ale District in Bulukumba Regency has agroecological conditions that support the development of organic rice, and several farmer groups have begun implementing environmentally friendly cultivation practices. Rising demand for organic rice has encouraged farmers to shift toward production systems that meet certification standards. This study aims to assess the level of adoption of certified organic farming practices among farmers, which is essential for strengthening farmer institutions and improving their capacity to consistently apply certification requirements. The study was conducted from May to July 2025 in Bontobangun, Bajiminasa, Bontoharu, and Karama Villages using qualitative descriptive analysis and a Likert scale. The findings show that adoption of organic certified practices is progressing, although not yet consistent across all stages. Farmers’ awareness is strong, supported by their understanding of organic principles and restrictions on chemical inputs. Their interest has formed through group interactions and perceived environmental benefits. At the evaluation and trial stages, farmers remain at a moderate level, indicating a need for stronger technical and administrative support. The adoption stage has begun to appear but lacks stability due to limited capacity, facilities, and institutional backing. Overall, adoption is in a transitional phase that requires systematic reinforcement to achieve sustainable organic farming.
