Applications that are able to predict plants growth patterns as a function of the nutrients obtained from fertilization pattern, is very useful in agriculture. Studies on the characteristics of the plants growth model is dynamic and highly complex, making it difficult to reach using conventional mathematical equations and geometric. The purpose of this study was to design and build a system of plants growth simulation models with Neuro-fuzzy method, then visualized by methods Lindenmayer system represented by three-dimensional use of Turtle Geometry. As the object of research is Soybean (Glycine max (L.) Merrill). Modeling parameters is long growth trunk / branches (L), a wide cross section of the leaf (W), and branch growth (B), as a function of changes in the fertilising elements Nitrogen (N), Phosphate (P) and potassium (K). Modeling done on the vegetative phase of the soybean crop. The initial step of this system is the modeling output L, W, and B as a function of changes in the values of NPK in the input system, using neurofuzzy (ANFIS). The next is to recognize the input string to be represented Lindenmayer coordinates into 3-dimensional method Turtle Geometry. The final step is to combine plant growth pattern parameters (L-W-B) into the visualization process plant structure in 3-dimensions. The test results on the system to grow plants pattern proves that ANFIS method is quite adaptive to variation of NPK value changes, and able to predict the output value L, W, and B. The final result of string-set of L-system and also it's visualization by Turtle Geometry, has proven to be influenced by variations in the composition of NPK values. Overall, the system has been running as expected.
