Abstract
Penelitian ini bertujuan untuk mengidentifikasi karakteristik lahan yang menjadi faktor pembatas, mengevaluasi kesesuaian lahan aktual dan potensial untuk tanaman padi (Oryza sativa L.) dan jagung (Zea mays L.), serta mengusulkan tindakan pengelolaan lahan yang tepat di Kecamatan Kebomas, Kabupaten Gresik. Penelitian dilaksanakan pada November 2025 hingga Februari 2026 dengan menggunakan metode survei evaluatif. Titik pengambilan sampel tanah ditentukan melalui purposive sampling berdasarkan hasil overlay, dengan delapan titik sampel untuk lahan padi dan delapan titik untuk lahan jagung. Sampel tanah diambil pada kedalaman 0– 30 cm dan dianalisis melalui observasi lapangan, uji laboratorium, serta analisis matching, scoring, dan overlay menggunakan ArcGIS. Parameter yang diamati meliputi drainase, kedalaman tanah, tekstur, karbon organik, pH tanah, kapasitas tukar kation, curah hujan, suhu, jumlah bulan basah, dan ketersediaan air. Hasil penelitian menunjukkan bahwa kelas kesesuaian lahan untuk padi dan jagung di Kecamatan Kebomas berkisar dari sangat sesuai (S1) hingga cukup sesuai (S2). Untuk padi, kelas S1 ditemukan pada P.T1, P.T6, dan P.T7, sedangkan lokasi lainnya termasuk dalam kelas S2 dengan kemiringan lereng sebagai faktor pembatas utama. Untuk jagung, kelas S1 ditemukan pada J.T1, J.T6, dan J.T7, sedangkan lokasi lainnya termasuk dalam kelas S2 yang terutama dibatasi oleh pH tanah dan kemiringan lereng. Secara keseluruhan, lahan di Kecamatan Kebomas memiliki potensi yang baik untuk budidaya padi dan jagung, dan tingkat kesesuaiannya dapat ditingkatkan melalui pengelolaan faktor pembatas secara tepat dan berkelanjutan. Kata Kunci: jagung (Zea mays L.), Kecamatan Kebomas, Kesesuaian lahan, padi (Oryza sativa L.), overlay SIG This study aimed to identify land characteristics that act as limiting factors, evaluate the actual and potential land suitability for rice (Oryza sativa L.) and corn (Zea mays L.), and propose appropriate land management practices in Kebomas District, Gresik Regency. The research was conducted from November 2025 to February 2026 using an evaluative survey method. Soil sampling points were determined through purposive sampling based on overlay results, with eight sampling points for rice fields and eight sampling points for corn fields. Soil samples were collected at a depth of 0–30 cm and analyzed through field observations, laboratory testing, as well as matching, scoring, and overlay analyses using ArcGIS. The observed parameters included drainage, soil depth, texture, organic carbon, soil pH, cation exchange capacity, rainfall, temperature, number of wet months, and water availability.The results showed that the land suitability classes for rice and corn in Kebomas District ranged from highly suitable (S1) to moderately suitable (S2). For rice, the S1 class was found at P.T1, P.T6, and P.T7, while the other locations were classified as S2, with slope being the main limiting factor. For corn, the S1 class was identified at J.T1, J.T6, and J.T7, whereas the remaining locations were categorized as S2, mainly limited by soil pH and slope. Overall, the land in Kebomas District has good potential for rice and corn cultivation, and its suitability level can be improved through proper and sustainable management of limiting factors.
