Food needs that continue to increase rapidly along with population growth and the conversion of optimal paddy fields to non-agricultural land make sub-optimal land an alternative rice-producing land. One of the sub-optimal land being developed for use as a source of rice production is tidal land. The purpose of this research is to improve the productivity and feasibility of rice farming by supervising double row technology in tidal land in Barito Kuala Regency. The performance of rice the new superior varieties of Inpara 2, inpara 8, inpari 32, inpari 40 and inpari 42 in the tidal swampland in the 2018 dry season are quite good. How to plant with super double row planting increases productivity by 43% compared to ordinary planting. The highest productivity with super double row is Inpara 2 variety (5.83 t / ha), then inpari 42 (5.19 t/ha), Inpara 8 (4.78 t/ha), Inpari 40 (4.23 t/ha), Inpara 3 (3.85 t / ha) and Inpari 32 (2.54 t/ha). The planting method with super double row gives an RC ratio of 2.07 and a R/C ratio of 1.07. Whereas the R/C ratio planting of the farmer way is 1.60. And the MBCR (marginal benefit-cost ratio) super double row 2.41. This shows that rice farming using super double row provides benefits and worth applying.
