Abstract :
Indonesian government plans to declare self-sufficiency in 2014 are now starting to be prioritized. One strategy that is required is increase of productivity. Increased productivity of sugar can be achieved by replacing old varieties degraded genetic superiority with new varieties, land expansion, improvement in farming systems and soil management. Therefore, the development of new sugar industry is more advisable for expansion in outside of Java. The area of considerable potential for the development of the sugar industry, especially in the expansion of sugarcane planting area is in Bangkalan, Madura Island. This study begins by taking soil samples in 18 villages spread over 6 districts, Bangkalan, Madura. The research method is using the survey method. Soil sampling using the "randomly selected". Land suitability sub-class assessment is views from land scores that compared to the reference land use requirements table, then matching the data carried by land suitability classification that based on a reference from the FAO. Fertility capability classification assessed by reference from Sanchez and Buol where units of fertility capability classification are assessed by type, sub-type and modifier. Structuring varieties performed by comparing the data between the classification results based on the typology of regions with land suitability classification table. The results showed that the land suitability classification system has gained 9 different subclasses of land suitability and soil fertility capability classification has gained 11 units of soil fertility capability. Interpretation of land suitability classification showed no clear relationship to the ability of soil fertility unit, and the interpretation of soil fertility capability units do not show a clear relationship to the land suitability class anyway. In every land that has a different sub-class, the recommended varieties were also different depending on the typology of each region. However, there are several lands that have different sub-classes of land suitability but matched with the same variety. Keyword : Suitability, Capability, Fertility, Sugar Cane, Varieties, Typology
