Abstract

The purpose of this research is to obtain the suitable model to overcome domestically-produced soybean provisioning. This research is carried out through surveying, interviewing, and handing out questionnaires to relevant institutions which are the Department of Agriculture of Soybean, Integrated Village Service Unit, Centre for Research and Development, Farmer Group, and lastly, Soybean farmers from Jember and Banyuwangi Regency. The way to determine the factors and indicators are using Fishbone Diagram, analysis from the mean value of questionnaire results, Validation and Reliability Test, and Linearity Test using SPSS17 for Windows, Measurement Model, Model Validity Test, and Hypothesis Test using PLS Version 2.0. The result of this research indicates mean value of 4.46 which means that respondents mostly agree with the proposed factors and indicators. Data are found to be valid, reliable, and they fulfill the linear assumptions with quadratic and cubic equations. The result for hypothesis test are: significant with 85% confidence level, model is valid, the proposed model which are Y1 (High production) is 100% influenced by X2 (Sufficient capital) and is 95% influenced by X5 (Land and Intensification), Y2 (Domestically-produced Soybean inventory) is 89% influenced by X1 (Reasonable farmer selling price), 100% influenced by X6 (High productivity), and 88% influenced by Y1 (High production).
