Judul: Analysis of the potential areas for directions to preserve paddy fields in Solok Regency- West Sumatera Province
Abstrak: The increasing of rice production by the programme of rice intensification and the controlling of paddy fields conversion becomes very important to maintain food security considering the increasing of paddy fields raw area has been difficult to be realized, mainly due to various barriers of economic and social factors, such as land status, remote location and the lack of manpower. Therefore, to ensure the food security, the priority areas that need to be preserved as paddy fields have to be set. The objective of this study was to analyze the potential of the region to be preserved as the paddy fields. The results of this study showed that there is 3.198 ha of area in Solok Regency which is suitable to be developed as paddy fields that is currently the grassland/tall grass, shrubs, bushes and fields. There are six districts namely Gunung Talang, Bukit Sundi, Kubung, Lembang Jaya, X Koto Singkarak and Junjung Sirih which is the most potential to be preserved as paddy fields by considering the availability of the technical irrigation network and the wide of semi technical, simple and village irrigation network, the value of cropping index that is more than 2 times per year and the level of paddy productivity that is more than 4,5 tons per ha. Moreover, the existence of subsidies or incentives for farmers is necessary to implement high yield productivity of farming so it could provides welfare for farmer families.

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
