Abstract

Karanganyar Regency is a food granary (rice surplus area), however at the moment, a large portion of agricultural land is undergoing land-use conversion, which may result in a drop in rice output and, if not regulated, a negative impact on food security. The research purpose is to analyze the distribution pattern of land use conversion and the level of food security in Karanganyar Regency, Central Java Province, to determine a sustainable food land direction. The distribution pattern of agricultural land conversion to non-agriculture was examined using the average closest neighbor (ANN=z-score), while data on agricultural land conversion to non-agriculture were gathered using LANDSAT satellite imagery. Due to the fact that the population is distributed over all sub-districts, all sub-districts are observed as study units (survey method). The study's findings are based on the fact that the z-score value (nearest neighbor spread index) from the ANN analysis is -2.553, indicating that the pattern of land-use conversion at the regency level is clustered, whereas at the sub-district level, there are three clustered sub-districts (clustered), three random sub-districts (random), and eleven dispersed sub-districts. At the regency level, Karanganyar Regency was a rice surplus area till 2019, with a population of 886519 people and a capacity to eat food (padi = rice) of up to 939795 people, leaving 53276 persons (939795-886519). (surplus area). Six sub-districts have a large surplus, eight have a modest surplus, and three at the sub-district level. The research results indicate that three sub-districts are appropriate for conversion to regional development areas, while rice barns are located in eight sub-districts and the remainder as buffer areas in as many as six sub-districts. A buffer zone is an area (district) that can be transformed under highly rigorous conditions to achieve long-term food security. Keywords: land-use conversion, rice surplus, food consumption
