Swampland will be the foundation of future food security, because irrigated paddy fields are very vulnerable to the land transfer functions, as happened on the Island of Java. Swampland has considerable potential to develop into food-based agriculture land in support of national food security. Swampland is divided into two types, namely: 1) tidal swamp and 2) waterlogged swamp. Land reclamation from tidal swamps for rice field in Riau province, covering an area of 80,868 ha, with low productivity at around 3.5 to 4.5 t ha−1 and average cropping index (CI) 100. This study aims to examine the application of technological innovation to improvement of rice cropping index. Referring to rice potential planting calendar of Riau Province, the planting season on rainy season 2019/2020 (October 2019 - March 2020) and the average rice cropping index of dry season 2020 were 171.49 percent. The application of Jarwo Super Planting Calendar of Rice crop productivity reached 5.73 t ha−1.
