Increasing Index of Paddy Plantation on Lebak Swamp with Polder System

Utilization of lebak swamp as an effort to expand the planting area is carried out by seeking an increase in the Planting Index (IP) through optimizing water and land resources and utilizing appropriate technology. To make lebak swamp is suitable for use as paddy fields, the method that can be done is by improving water management to meet the needs of plants. Improvements to water management are carried out by controlling the water level of the land using a closed polder system, which is irrigation when the plants of lack water and drainage when the water is over. It is necessary to regulate water equilibrium so that land does not experience flooding and drought, it is necessary to calculate water balance on the land through the water balance. A suitable cropping pattern to be applied with a polder system can be carried out into several patterns such as fallow - rice - rice and so on. After knowing cropping patterns and crop productivity levels, financial feasibility analysis was carried out. Based on the financial feasibility analysis, this polder system meets the value requirements for the parameters of financial feasibility.
