Spatial analysis of the relation of rice land area and rice production using remote sensing imagery

Abstract

Indonesia is the country with the largest rice producer. One of the provinces that is a national rice granary is West Java Province, specifically Cianjur Regency which is the third largest contributor of rice products in West Java. In determining the area of rice fields, knowledge of spatial information is very necessary, processing can be done using remote sensing. Remote sensing is able to detect land use and land cover changes. The data needed is Landsat 8 imagery in 2013 and Landsat 8 imagery in 2020. This spatial analysis of land change passed an accuracy test using the Kappa Coefficient method. The results of the analysis carried out over a period of 7 years showed that there was an increase in the area of rice fields amounting to 16671.2 Ha. From this relationship, the 2013 image calculation gets a production value of 801,622 tons or 8.02 tons per hectare, and the 2020 image gets a production value of 1,108,388 tons or 7.89 tons per hectare.
