Purpose -The purpose of this paper is to examine and analyze the factors of availability, access, and absorption affecting the level of food security and its impact on the community welfare. Design/methodology/approach -This study focuses on food security and community welfare in all provinces in Sumatra. Available data are obtained from sustainable development goals (SDGs) data in 2015 (Badan Pusat Statistik, 2016), with the district/city in Sumatra as unit analysis, with the number of samples 152 districts/cities. The causal relations between variables (the relationship between availability (X1), accessibility (X2), and absorption (X3) and effect of food security (Y1), and the relationship between food security (Y1) and community welfare (Y2)) were examined using covariance-based structural equation modeling using WarpPLS. Findings -The conclusion of this study shows that the availability, accessibility, and absorption statistically influence the food security. On the other hand, the food security statistically influences the community welfare. Originality/value -Until now there is no previous research that brings food security factors integrated with the community welfare, and no one has studied the full modeling on the Sumatra, Indonesia, and the use of SDGs data intact considering the new data of 2015 SDGs collected replacing the millennium development goals data.
