Kajian Spasial dan temporal Fase Tmbuh Padi sawah dengan aplikasi Citra Sentinel-1 SAR di Kabupaten Karawang 2017

Rice phenology is mainly defined as the growing stages that occurs within a rice plantthat begins when the rice is planted in the ground and ends when the rice is ready for harvesting. Sentinel-1 Synthetic Aperture Radar Images at the C-Band are capable of monitoring rice phenology. Rice phenology is divided into five classes using maximum likelihood classification according to BPPT area sampling survey which are land preparation, early vegetative, late vegetative, generative, and harvesting. This research aims to provide a spatial and temporal assessment of rice phenology in Karawang according to Sentinel image analysis. Results of this study show that rice which grows quickly is distributed in northern irrigation areas that receive water last compared to southern and middle Karawang irrigation areas. Rice growth phase distribution does not follow Karawang irrigation pattern. Rice in northern irrigation areas have the lowest backscatter values. Rice reaches harvesting stage quicker in dry season compared to rainy season with the same backscatter values.
