Abstract

Abstract: Marginal land development in Situbondo Regency has not yet received special attention from farmer as the farmer-enterpreneur, so that the efforts made by stakeholders have not yet gotten maximum results. Therefore, increasing awareness and understanding of the development and use of marginal area is needed. The objectives of this study are: 1) knowing the land characteristics of crops commodities at marginal land and (2) mapping the suitability of cropland at marginal land. The locations of the study are Jatibanteng and Sumbermalang Subdistricts with the consideration that the subdistrict is the area where the majority of rice fields are dry and marginal area in Situbondo Regency. The research method uses an analytical approach. The data collection method is using secondary data, which is available statistical data that has been published by BPS and primer data. The data analysis method uses SRTM (Shuttle Radar Topography Mission) and soil chemical analysis. The results showed that of (1) the land characteristics can be seen from soil chemical analysis including: a) Phosfor content of land ranged from 28, 06-84, 28 me/100g which was dominated by high status; b) Potassium value of land ranged from 16.95-59.96 me/100g which was dominated by moderate status; c) Organic matter content of land ranged from 1.75-3.39% which was dominated by medium status; d) Cation Exchange Capacity (CEC) value of land ranged from 14.76 - 37.03 me/100g which was dominated by the high status; and e) Base Saturation in Jatibanteng Subdistrict was classified as low to moderate, ranged from 30.39% - 50.10% and Sumbermalang subdistrict ranged from 20.15% - 48.62%. Provision of organic material is a way that can be applied to increase the value of BS, because organic matter affects soil properties such as its physics and chemistry. (2) Meanwhile the the second objective was found that: a) around 35% of Jatibanteng Subdistrict was in the S1 (Highly Suitable) category; on the other hand, Sumbermalang Subdistricts was in the S2 (Moderately Suitable) and S3 (Marginal Suitable) categories for the rice field suitability, b) class suitability of corn in the study area was included in the more dominant of S2 (Moderately Suitable) category reaching almost 85% of the land areas, and c) cassava plants had an S1 (Highly Suitable) suitability class dominated by Jatibanteng Subdistrict which was almost 50% of its areas in Sumbermalang Subdistrict with the suitability of S2 (Moderately Suitable) and S1 (Highly Suitable).
