The Effect of Slope Chamfer on Hydroponic NFT (Nutrient Film Technique) System For Cultivitation Of Japan Spinach (Spinacia Oleracea L.)

NFT is a hydroponic cultivation system by putting the roots of plants in a thin layer of water where the plants get nutrients from the nutrient solution that flows through the gutters, the flow of nutrient on NFT hydroponic circulated continuously so that the plant's nutritional needs can be fulfilled. NFT hydroponic vegetables is suitable to be cultivated for leafy vegetables, like a Japanese spinach plant (Spinacia Oleracea L.). The purpose of these research was to test the design of NFT Hydroponic with slope 3%. In the testing performance of hydroponic NFT consist of three parameters. These parameters include the testing of irrigation efficiency, pH values ​​and Electrical Conductivity (EC) solution and the uniformity of crop productivity. Data obtained from this study were analyzed based on its design to determine the effect of each parameter on plant growth. The average irrigation efficiency value is 92.00%, the value of uniformity electrical conductivity (EC) reached 92.10% and the uniformity of solution pH value reaches 99.51%. For the final harvest that obtained from its various agronomical aspects result obtained is the uniformity of the result obtained in plan weight gained is the smallest weight 13 grams and the heaviest 70 grams. From 32 plants produced, uniformity values obtained of plant weight at 67.788% (chamfer 1), 68,388% (chamfer 2) and 68,388% (chamfer 3).
