| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui : (1) Distribusi unsur hara S tanah di lahan sawah yang digunakan untuk budidaya tanaman padi sawah wilayah sub DAS Serayu hilir di Kecamatan Maos Kabupaten Cilacap, (2) Sifat kimia tanah meliputi pH H2O, pH KCl, Potensial redoks dan DHL (Daya Hantar Listrik) pada lahan sawah, (3) Mendapatkan rekomendasi pupuk untuk lahan persawahan. Penelitian dilaksanakan di lahan sawah Wilayah Sub DAS Serayu Hilir di Kecamatan Maos, Kabupaten Cilacap dengan ketinggian tempat 198 mdpl dan Laboratorium Ilmu Tanah, Fakultas Pertanian, Universitas Jenderal Soedirman pada bulan Januari 2021 hingga Mei 2021. Penelitian ini dilakukan dengan metode survei pada tingkat semi detail dengan skala 1: 50.000. Peta satuan lahan (SLH) dibuat dengan cara tumpang susun (overlay) peta administrasi, peta kelerengan, peta jenis tanah dan peta penggunaan lahan kecamatan Maos. Pengambilan sampel tanah dilakukan secara komposit di Lokasi penelitian. Sampel tanah diambil pada kedalaman 0-25 cm dan 25-50 cm secara acak (zigzag). Hasil penelitian menunjukkan bahwa terdapat kandungan sulfur tersedia di lokasi penelitian pada kedalaman 0-25 cm bersifat rendah sampai sedang (35,68-86,27 ppm). Hasil analisis sifat kimia tanah di lahan sawah Kecamatan Maos menunjukkan bahwa pH H2O bersifat netral dan pH KCl bersifat agak masam hingga masam, daya hantar listrik sangat rendah, dan potensial redoks tereduksi rendah. Korelasi antar variabel 3,58% hasil tanaman padi di lahan sawah dipengaruhi oleh S-tersedia tanah, 4,39% hasil tanaman padi di lahan sawah dipengaruhi oleh pH H2O tanah, 2,38% hasil tanaman padi di lahan sawah dipengaruhi oleh pH KCl tanah, hasil tanaman padi dipengaruhi oleh DHL yaitu sebesar 11,64% dan hasil tanaman dipengaruhi oleh potensial redoks sebesar 21,21%. Rekomendasi pemupukan sulfur untuk tanaman padi sawah Kecamatan Maos yaitu sebesar 16,95-40,99 kg S/ha atau setara dengan pemberian pupuk ZA sebesar 70,64-170,81 kg ZA/ha. |

| Abtrak (Bhs. Inggris) | This study aims to determine: (1) the distribution of soil nutrients in rice fields used for rice cultivation in the downstream Serayu sub-watershed area in Maos District, Cilacap Regency, (2) Soil chemical properties include pH H2O, pH KCl, Redox potential and DHL (Electricity Conductivity) in paddy fields, (3) Get fertilizer recommendations for paddy fields. The research was carried out in the rice fields of the Serayu Hilir Sub-Watershed Area in Maos District, Cilacap Regency with an altitude of 198 meters above sea level and the Soil Science Laboratory, Faculty of Agriculture, Jenderal Sudirman University from January 2021 to May 2021. This research was conducted using a survey method at the semi-detailed level with a scale of 1: 50,000. The land unit map (SLH) was made by overlaying administrative maps, slope maps, soil type maps and land use maps in Maos sub-district. Soil sampling was carried out in a composite manner at the research site. Soil samples were taken at a depth of 0-25 cm and 25-50 cm randomly (zigzag). The results showed that the sulfur content available at the research site at a depth of 0-25 cm was low to moderate (35.68-86.27 ppm). The results of the analysis of soil chemical properties in paddy fields Maos subdistrict showed that pH of H2O was neutral and the pH of KCl is slightly acid to sour, very low electrical conductivity, and low redox potential is reduced. The correlation between variables 3,58% yield rice plants in paddy fields affected by the S-provided land, 4,39% yield rice plants in paddy fields affected by pH H2O soil, 2,38% yield rice plants in paddy fields affected by pH KCl soil, rice yields are influenced by DHL which amounted to 11,64% and crop yields were affected by the redox potential of 21,21%. The recommendation for sulfur fertilization for lowland rice in Maos District is 16,95-40,99 kg S/ha or the equivalent of 70,64-170,81 kg ZA/ha. |
