【 摘 要 】

Rice yield in Java Island as national rice supplier in order to support food security. Java has a dense population, causing very high pressure on land use. The need for housing, roads and industrial infrastructure encourages the conversion of agricultural land for other land uses. This study aims to formulate strategies for the purpose of maintaining food security in flood-prone areas. Karawang Regency is a rice barn of West Java Province and is also a frequent area of flooding. Therefore, it is necessary to map the spread of flood-prone areas and to analyze land use linkages, rice productivity, population and food needs in the study area. Strategies for maintaining spatial food security are by mapping land cover multi years and mapping the flood hazard areas using high-resolution DEM data. Land cover mapping using RBI Map Scale 1: 25,000 the Year 2000 and Citra Landsat-8 and Spot-6 Year 2015. Wetland Area Year 2000 is 120,371 (62.83%), land area Year 2015 is 98,462 ha (51.40%). The average rice field area caused by flooding reaches 219.84 ha/year, if the productivity of 6.9 tons/ha annually loses rice production on average 1,517 tons. Food security in the research area is still maintained from various pressures of land use. There is unfulfilled support for national food security with the obligation to provide 1.5 million tons of paddy stock per year. The selection of strategies in maintaining food security in the research area is to tighten supervision in licensing in favor of the protection of paddy fields. The professionalism of agricultural extension resources will be able to increase rice productivity.
