The Analysis of Quality of Paddy Harvest Yield to Support Food Security: A System Thinking Approach (Case Study: East Java)

Abstract

Rice (Oryza Sativa) is a staple food for the people in Indonesia. East Java Province is a province with potential agricultural in Indonesia. East Java has advantages in agriculture and has a role in the national food sector. Population in Indonesia is projected to reach 271.1 million by 2020. East Java’s population growth rate from 2010 to 2017 was 0.64% with consumption of 213,783 tons of rice in 2018. Raw materials such as paddy, are perishable materials that require fast and precise handling. When handling is not right it will cause a loss of the results of high quality and quantity, this can be harmful to farmers because it will affect their income. This study uses a system dynamic to build the conceptual model (Causal Loop Diagram) to improving the quality of paddy yields to support food security. The results of study are a model that has some useful information regarding factors that affect the quality paddy. This can be used as decision support by the government for decision making about policies that will be applied to improve the quality of paddy harvest yields for support food security. Further research can be carried out by simulating several scenarios to predict the state of the rice farming system in the future.
