Edamame soybean is a kind of soybean included as a vegetable that is eaten while still green (green soybean vegetables). Edamame has high nutrition, that is why edamame has a high marketing chance. To get a high productivity of edamame soybean, it needs water with precision. Water is an abiotic element very important to life, not enough water in agricultural field causes decreasing productivity while on the other side too much water causes negative effect to plant other than increasing the cost of production. The increasing of population around the world causes the increasing of competition in using water as for human or for agricultural. That is why, the knowledge of water optimalization is needed, to get maximum productivity in water efficiency on culture system. The objectives in this research are to discover the equation of water precision modelling on Edamame Soybean on two medias, cocopeat and rice husk charcoal, these are non – dirt media because in the near future with the increasing of population field are hard to be found and we need the alternatives media other than dirt. And then to determine the highest productivity of edamame soybean. From two medias above, given treatment are water with 25%, 50%, 75% and 100% media capacity. In conclusion Mathematical equiation of cocopeat media and rice husk charcoal media are Y = -5 x 10-6x3 + 0.0006x2 – 0.0257x + 1.0372 and Y = 2x10-5x3 – 0.0023x2 + 0.0883x – 0.0413. The highest productivity of Edamame soybean is in rice husk charcoal that had given treatment with 100% roomy capacity with productivity per plan is 46.99 gram
