摘要：Land suitability and availability is needed to be evaluated in Brebes Regency because the utilization of unsuitable land area is increasing to pursue high production targets as the impact of increased shallot demand. The objective of this research was to evaluate the land suitability and land availability for shallot farming development in Brebes Regency, an agricultural regency in Java Island. The method used was the matching method between shallot growing pre-requirement criteria from Indonesian Center for Agricultural Land Resources Research and Development (CALRRD) with land quality and characteristics in Brebes Regency. Since limited data, we used an interpolation techniques from 14 sample point by using geostatistical wizard tool in ArcGIS 10.3 with inverse distance weighting (IDW) method for nutrient retention and climatological data, while soil physical properties from soil map attribute data extraction, meanwhile terrain data were constructed from digital topographic maps (contour line). For land availability, the analysis was done on areas that are legally based on the spatial pattern and the status of the forest area which is intended for agricultural development. The result indicated that suitable land for shallot farming development was 29.3% or 50 440.7 hectares included in the Moderately Suitable (S2); 55.5% or 95 819.9 hectares in Marginally Suitable (S3); while Not Suitable (N) was 14.8% or 25 678.3 hectares. The available land for agricultural farming based on legality was 59 076.0 hectares (without considering the existing shallot farming), while the suitable land area on available land was 56 642.6 hectares. The existing shallot land area was 49 840.3 hectares, so the available and suitable land area on existing land for shallot farming was 49 099.5 hectares, and potential extensification was 6 417.9 hectares as shrubs, grasslands, open land, and forest.
