Tujuan penelitian untuk mengkaji pengaruh variasi ketinggian <em>raised bed</em> terhadap perubahan sifat fisik dan kimia tanah terpilih. Penelitian dilaksanakan pada bulan Juni hingga Agustus 2025 di Jemur Wonosari, Surabaya. Rancangan Acak Kelompok digunakan untuk mengevaluasi perlakuan ketinggian <em>raised bed</em> : 20 cm (P₁), 25 cm (P₂), dan 30 cm (P₃), masing-masing diulang tiga kali. Sampel tanah diambil pada kedalaman 0-20 cm pada setiap <em>raised bed</em> untuk dianalisis nilai pH tanah, EC, dan C-organik tanah. Hasil penelitian menunjukkan bahwa ketinggian <em>raised bed</em> mempengaruhi nilai ciri tanah tersebut. Nilai pH tanah berada pada kisaran 7,08–7,63, nilai EC tanah antara 0,594 dS/m dan 0,402 dS/m, dan kandungan C organik antara 1,09% dan 0,6%. Kandungan C organik berbanding terbalik dengan EC tanah. Bedengan yang ditinggikan optimal pada ketinggian 25 cm karena dapat menjaga kelembapan, aerasi, dan mendukung dekomposisi bahan organik yang baik.</p> Chosa Zahro Fatiha Wanti Mindari Purnomo Edi Sasongko Rahayu Anggraini Fifi Aurafika Dewi Iqbal Satria Pradana Copyright (c) 2026 Chosa Zahro Fatiha, Wanti Mindari , Purnomo Edi Sasongko, Rahayu Anggraini, Fifi Aurafika Dewi, Iqbal Satria Pradana https://creativecommons.org/licenses/by/4.0 2026-01-22 2026-01-22 14 1 37 43 10.33005/plumula.v14i1.275
