The SERASI will convert a non-productive caved swamp areas to a productive rice fields which able to support regional food security sustainably. In order to able define the suitable marshland area for SERASI Program in HST Regency precisely in the era of pandemic Covid-19, this research had been carried out by applying geospatial analyses method using Sentinel Satellite Imageries acquisitioned from two different epochs, i.e. of 20 th  February 2019 and of 20 th  February 2020. GPS coordinates collected from the field were used for ground truthing imagery data. The results of geospatial analysis have provided evident that paddy fields in caved marshland area is increased that means the SERASI Program is successful.
