Abstract

This study sought to develop a structural model of anthracnosis disease attack and red chili production in five production centers in East Java, Indonesia, with the goal of controlling disease by way of manipulating cultivation techniques and environmental factors. This research was conducted using a field survey method in five areas of East Java red chili production during the rainy season from November 2017 to January 2018. In each area of red chili production, we surveyed 13 to 20 farmers’ gardens using purposive sampling. We analyzed the data by multivariate analysis using the SmartPLS 3.0 student version (S martPLS GmbH, Bönningstedt. Germany). The structural model showed a predictive relevance (Q2) value of 0.9809, meaning that 98.09% of the data were explained in the model and 1.91% of the data were defined as unobserved. Based on the structural model, anthracnose disease attacks are significantly affected by climate and soil variables, while cultivation techniques impose an indirect effect by way of soil variables. The harvest of red chili is also directly affected by the variable percentages of disease, soil, cultivation techniques, and geographical factors. In conclusion, our structural model of anthracnose disease attacking red chili production centers in East Java showed high predictive relevance.
