Opportunities for increasing production of edamame soybean cultivation are still wide open, especially to meet local and export demand. Through the application of precision farming systems, it can support edamame soybean production. One important component in agricultural farming is knowing the need for water in aquaculture so that it can save costs and increase productivity. This research uses a mathematical modeling to determine the water requirements in edamame soybean production with a polynomial line equation simulation approach so that optimal water requirements can be identified every day for 65 days after planting. Optimal water requirements for plants can be seen from the optimal plant growth with the parameters of the number of leaves and plant height. The media used in this study are soil media and sawdust media. In the soil media the equation y = 0.0063x2 - 0.4166x + 102.82 and the sawdust media obtained the equation y = 0.0049x2 + 0.0457x + 63.709 where the range of water demand is between 66% to 110%. This is supported by the results of biomass production which shows that the highest treatment of pod biomass is the provision of water 100% of groundwater capacity, and the highest stover biomass is giving 100% to soil media and 75% to sawdust media. The highest chlorophyll content was shown by giving 100% water to the soil and 25% to the sawdust and 75% water treatment in both media showed the highest total dissolved solids.
