Soil index plasticity is an important soil physical property of the soil related to the tillage intensity , especially if it is done by machine such as a tractor. This study aim is to build an artificial neural network (ANN) model that connects the soil texture with the soil index plasticity. The research was conducted in several stages, namely: (1) soil texture determination, plastic limit and liquid limit in the laboratory, (2) plasticity index calculation, (3) Soil texture-soil plasticity index ANN model built. ANN models are created using 3 input variables, namely x1: clay content, x2: silt content and x3: sand content. The model uses 2 layers, with a logsig-tangig-purelin activation function. The results of the model training resulted in a RMSE (Root Mean Square Error) value of 1.6542 and an R2 value of 0.9570. Model validation produces a correlation value of predictive data and R2 observation data of 0.9332 Keywords: artificial neural network models, soil consistency, soil physical properties, soil texture
