摘要：Agricultural land is part of the earth as a gift of God which is controlled by the state and utilized for the prosperity and welfare of the people, as mandated by the Constitution of the Republic of Indonesia 1945.The existence of agricultural land can provide great benefits for economic, social, and environmental.Land use change from agricultural to non-agricultural, causing decreased productivity of agricultural land, so that it appears the hypothesis that the decline of agricultural land will affect food security.Based on these problems, the research conducted to assess the relationship between land use change in agricultural with food security; a case study in Magelang District in 2009 until 2011.This research method using the spatio-temporal GIS, quantitative analysis, and field calibration.The results showed, that agricultural land area decreased 6.31%, but food security is not declining, because the food source of Magelang regency come from several areas around.From these results it can be concluded that the reduction of agricultural land does not significantly affect the food security status of the certain area, but in the long term, the decline of agricultural land will affect national food security.So, to maintain food security, land use control is necessary to prevent degradation of agricultural land for the establishment of national food security.
其他摘要：As mandated by the 1945 Constitution of the Republic of Indonesia, agricultural land is part of the earth as a gift from God that is controlled by the state and utilized for the prosperity and welfare of the people. The agricultural land can provide great benefits in terms of economic, social, and environmental benefits. Land use conversion from agricultural to non-agricultural use can cause productivity decrease in agriculture, so it triggers a hypothesis that the decrease of agricultural land will negatively affect food security. Based on the problem, the research is conducted to assess the relationship between conversion in agricultural land use with food security using a case study of Magelang Regency (Kabupaten) in the 2009-11 period. The methods used are spatio-temporal GIS, quantitative analysis, and field calibration. The results have shown that the agricultural land area has decreased (6.31%) but the food security has not declined. It is because the food sources for Magelang Regency come from several adjacent areas. It can then be concluded that the reduction of agricultural land does not significantly affect the food security status of the study area. However, in the long run the decrease of the agricultural land will affect national food security. So, to maintain food security, agricultural land use control is necessary to prevent the unnecessary conversion of agricultural land.
