Abstrak: Land use defeated from paddy field agricultural land to non agricultural land has reached an alarming level. In order to maintain national food sovereignty required the protection of agricultural land by the establishment of sustainable paddy field agriculture land. For to realize the existence are need model (methods and techniques) to selection, deliniation and zonation for sustainable paddy field agriculture land (LPPB). Determination LPPB preceded by the parameters selection and criteria determination by Hayashi analysis. From this test can be formulated that LPPB is an paddy field agricultural land irrigated of technical, semi technical, simple (rain fed), which has a productivity of over 4.5 tonnes / ha, had a Benefit Cost Ratio (BCR) > 1.497 and has a Size of Unity Land Cover (LKHL) > 10 ha. Irrigation systems and LKHL parameters data can be extract from the ALOS AVNIR-2 imagery, the productivity data can be determined by the Enhanced Vegetation Index (EVI) data from MODIS Terra and Aqua series (2005-2009) imagery. The EVI on picpoint and productivity of paddy fields has a positive correlation with the equation Prod. = 2.9785 + 6.0751 * EVI value. BCR values obtained from the calculation of productivity and index investments obtained from MODIS imagery are combined with data from the production cost of rice paddy land acquired from field surveys. LPPB selection techniques can be built through remote sensing methods. Activities starting from parameter data extraction through the sattelite image, field survey, development of criteria according to field conditions, LPPB classifying through spatial analysis and presentation of result in the LPPB maps. From this method was known that paddy field agricultural area can be diferences as LPPB1, LPPB2, LPPB3, LPPB4, LPPB5, Reserve of LPPB and Non LPPB.

Judul: Model for sustainable protection paddy fields and rice sufficiency in the Banyumas Regency, Central Java Province
Abstrak: Rice is a staple food for almost all the population in Indonesia and is a basic necessity for human life. Therefore, the State is essential to ensure its availability, affordability, and the adequate and quality fulfillment of food consumption evenly across all regions. Paddy fields are a crucial factor in rice production. Allowing continuous conversion of paddy fields in the long term poses a threat to efforts to meet rice sufficiency. The main objective of this research is to develop the model for sustainable protection of paddy fields and domestic rice sufficiency in Banyumas Regency, Central Java Province, with the following sub-objectives: 1) analyzing the dynamics of paddy field changes and trends in conversion, 2) evaluating the suitability classes of paddy fields for rice cultivation, 3) analyzing important variables and influential actors in the protection of paddy fields and sufficiency, 4) constructing a dynamic model and formulating policies for the protection of paddy fields and domestic rice sufficiency in Banyumas Regency. The research was conducted using a combination of several methods (mixed methods). Primary and/or secondary data were collected through various techniques, including literature review, desk analysis, in-depth discussions (in-depth interviews), internet downloads, and field observations. Respondents consisted of stakeholders and/or experts, namely: the Regent, Chair of the Regional People's Representative Council (DPRD), Head of relevant agencies or assigned staff, Agrarian Spatial Planning and National Land Agency (ATR/BPN), Academicians, Agricultural Extension Officers (PPL), Village Officials, farmer groups, farmers, settlement developers, fertilizer agents, and rice traders. The data analysis technique were adjusted to the research objectives. Changes in paddy field land use from 2007 to 2019 and their predictions for 2031 and 2045 were carried out through visual interpretation of SPOT image recordings in 2007, 2014, and 2019 using ArcGIS 10.8.2 and the Landuse Change Modeler (LCM) in the TerrSet software. The evaluation of land suitability classes was performed by a matching system between land characteristics and the requirements for growing rice crops. Important variables and the relationships between variables were analyzed using the Micmac method. Important actors and their involvement in paddy fields protection were analyzed using the Mactor method. The dynamic model for the protection of paddy fields and domestic rice sufficiency was developed by constructing a stock flow diagram (SFD) structure. The conversion of paddy fields into non-paddy fields in Banyumas Regency from 2007 to 2019 reached an area of approximately 1,231 ha (3.87%), with an average annual decrease rate of 102.6 ha/year and a potential loss of rice production of about 1,189 tons of harvested dry paddy per year. In 2045, it is estimated that the paddy field area in Banyumas Regency will be 29,160 ha, with a decrease rate from 2019 to 2045 covering an area of 1,384 ha (4.53%). The evaluation of land suitability classes for rice cultivation in Banyumas Regency indicates that the actual suitability of paddy fields consists of very suitable class (S1) at 52%, moderately suitable (S2) at 10%, marginally suitable (S3) at 38%, and not suitable (N) at 0.05%. The limiting factors encountered include soil pH, base saturation, and soil drainage. Several important
