Abstract
Abstract Agricultural land in Madiun District often experiences drought during the dry season, resulting in reduced plant tolerance to environmental stress. Silica plays a role in enhancing plant resistance to drought stress and in binding nutrients. Although silica is not classified as an essential nutrient, it is absorbed by plants in large quantities. This study aimed to examine the presence of soil silica and plant tissue silica under different land uses in Madiun District. The research was conducted in three land-use units (SPL) located in Gunungsari, Banjarsari, and Sirapan Villages, Madiun District, Madiun Regency. The methods included determination of sampling points, collection of soil and plant samples at depths of 0–30 cm and 30–60 cm, physical analysis (texture, moisture content), chemical analysis (pH, C-organic, N-total, cation exchange capacity/CEC, and silica content), followed by data processing using correlation and linear regression tests. The highest silica content in plant tissue was found in rice fields (40%), while sugarcane fields had (29%). The analysis of silica content in sugarcane fields showed the highest value in Banjarsari (57.31%) and the lowest in Sirapan (56.75%). Meanwhile, in paddy fields, the highest silica content was found in Gunungsari (66.69%) and the lowest in Sirapan (65.57%). The presence of silica influenced cation exchange capacity (CEC) and nitrogen availability in different land uses. The findings indicate that silica contributes to drought tolerance by reducing water loss through plant transpiration. Land management practices are recommended to increase silica availability, including the application of silica amendments or the return of crop residues to the soil Keywords : silica, absorption, land tillage Abstrak Kondisi permasalahan lahan pertanian di Kecamatan Madiun pada musim kemarau mengalami kekeringan sehingga kurangnya toleransi tanaman terhadap kondisi lingkungan. Silika mampu meningkatkan ketahanan tanaman pada cekaman kekeringan dan berperan dalam mengikat unsur hara. Silika bukan unsur hara esensial, namun banyak diserap oleh tanaman. Penelitian ini bertujuan untuk mengkaji keberadaan silika tanah dan silika jaringan tanaman pada berbagai penggunaan lahan di Kecamatan Madiun. Penelitian dilakukan di 3 lokasi satuan penggunaan lahan (SPL) yaitu Desa Gunungsari, Desa Banjarsari, Desa Sirapan, Kecamatan Madiun, Kabupaten Madiun. Metode penelitian meliputi penentuan titik sampling, pengambilan sampel tanah, sampel tanaman dengan kedalam 0-30 cm dan 30 – 60 cm, analisa fisika seperti tekstur, kadar air dan analisa kimia seperti pH, C-Organik, N-Total, kapasitas tukar kation (KTK) dan kadar Silika, kemudian olah data menggunakan uji korelasi dan regresi linear. Analisa silika jaringan tanaman paling tinggi adalah penggunaan lahan sawah dengan nilai 40% sedangkan tebu hanya 29%. Hasil analisa silika tanah lahan tebu didapatkan hasil tertinggi dilokasi Banjarsari dengan jumlah 57,31% dan terendah dilokasi Sirapan dengan jumlah 56,75%. Sedangkan hasil analisa silika penggunaan lahan sawah didapatkan hasil tertinggi dilokasi Gunungsari dengan jumlah 66,69% dan terendah dilokasi Sirapan dengan jumlah 65,57%. Pengaruh keberadaan silika adalah nilai kapasitas tukar kation (KTK) dan nitrogen penggunaan lahan. Hasil penelitian silika toleran terhadap kekeringan sehingga membantu mengurangi kehilangan air melalui trasnpirasi tanaman. Rekomendasi pengolahan lahan dengan menambah ketersediaan silika atau pengembalian residu tanaman Kata kunci : Silika, penyerapan, pengolahan lahan
