The suitability of typical rice varieties in Tegalampel Sub-District, Bondowoso District. The need for rice is increasing every year. Rice production is inseparable from paddy production in the field. Paddy production on the field will be optimal if the variety matches the soil and land characteristics. This research is an exploratory study to evaluate the suitability of the typical location of paddy varieties in Tegalampel Sub-District, Bondowoso District. The research was conducted in August-December 2020 in Tegalampel District, Jember Regency, and soil analysis at the Soil Fertility Laboratory of the University of Jember. The research method uses a survey method which is divided into 3 stages: literature study, field survey, and data analysis. The results showed Tegalampel Sub-District has the potential to be planted with paddy divided into 3 land uses with a height of <700 m asl with rainfall <2000 mm / year, namely irrigated rice fields, rain-fed rice fields, and dry fields / dry land. Suitability of rice varieties for irrigated rice fields namely Ciherang, Inpari 1, Inpari 6 Jete, Mekongga by 16.60%; suitability of rice varieties for rain-fed rice fields are varieties Inpari 10, Inpari 12, Inpari 13, Inpari 18, Inpari 19, Inpari 20, Inpari 38, Inpari 39, Inpari 40, Inpari 41, Dodokan, Silugonggo by 26.64%; and suitability of rice varieties for dry fields / dry land, namely Inpago 5, Inpago 8, Inpago 9, Inpago 10, Inpago 11, Inpago 12 by 26.35%.Kebutuhan beras semakin meningkat tiap tahun. Produksi beras tidak terlepas dari produksi padi di lapang. Produksi padi dilapang akan optimal apabila varietas sesuai dengan karakteristik tanah dan lahan. Penelitian ini merupakan penelitian eksplorasi dengan tujuan evaluasi kesesuaian khasloka varietas padi di Kecamatan Tegalampel Kabupaten Bondowoso. Metode penelitian menggunakan metode survei yang terbagi atas 3 tahapan yaitu studi pustaka, survei lapang, dan analisis data. Hasil penelitian menunjukkan Kecamatan Tegalampel berpotensi untuk ditanami padi yang terbagi atas 3 penggunaan lahan dengan ketinggian tempat < 700 mdpl dengan curah hujan < 2000 mm/tahun yaitu sawah irigasi, sawah tadah hujan, dan tegalan/lahan kering. Kesesuaian varietas padi untuk lahan sawah irigasi yaitu varietas Ciherang, Inpari 1, Inpari 6 Jete, Mekongga sebesar 16,60%; lahan sawah tadah hujan yaitu varietas Inpari 10, Inpari 12, Inpari 13, Inpari  18, Inpari 19, Inpari 20, Inpari 38, Inpari 39, Inpari 40, Inpari 41, Dodokan, Silugonggo sebesar 26,64%; dan kesesuaian varietas padi untuk lahan tegalan yaitu varietas Inpago 5, Inpago 8, Inpago 9, Inpago 10, Inpago 11, Inpago 12 sebesar 26,35%.   Kata kunci: kesesuaian lahan, khasloka, survai, varietas, pad
