Abstract

Rice is a staple food crop in Indonesia because most of the population consumes rice as a staple food. For optimal production, rice plants must be planted in paddy fields according to their designation and the growing plants’ requirements. Determination of land suitability class is essential to obtain a database as information on the suitability of the quality of the land characteristics so that the land suitability class and its limiting factors can be known as the basis for determining the necessary land improvement management. The study aimed to determine the land suitability class for lowland rice (Oryza sativa L.) in the Panasen and Noongan sub-watersheds. The long-term goal is for the preservation of sustainable paddy fields. The method uses a field survey, referring to the limiting factors of land quality described in the characteristics of the land. The data from the field measurements and the laboratory analysis results matched the criteria for the suitability class of lowland rice based on the Minister of Agriculture Regulation No. 79 (2013). The result of the research is that the land unit of S3 suitability class is S3rns on a land unit of 5, 9, with the limiting factors being root conditions, nutrient availability, and slopes. S3fn land unit on land unit 7, limiting factor for nutrient retention and nutrient availability, S3rfn land unit on land unit 8, limiting factor for root conditions, nutrient retention, nutrient availability, S3n land unit on land unit 10, 11, 13, 14, 15, 16, 17, 18 and 27, with the limiting factor of nutrient availability, S3ns in 12 land units, the limiting factor of nutrient availability and terrain. The land unit suitability class N is the land unit suitability class Ns on land units 1, 2, 4, 19, 20, 21, 22, 23, 24, 25, and 26, the field limiting factor. Land unit suitability class Nrs on land unit 3, with limiting factors for root and terrain conditions. Land unit suitability class Nr on land unit 6, the limiting factor for root conditions.
