The Production Pattern of Rubber Farming and Farmer Behavior in Dealing with Price Fluctuations in Jambi Province, Indonesia

This study aims to determine (1) the magnitude of the fluctuation in rubber prices (2) the pattern of production of rubber and the behavior of farmers in dealing with price fluctuations and (3) the elasticity of the supply of rubber in Jambi Province. This study uses a survey method with the scope of the study area being Jambi Province by selecting two villages purposively, namely Muhajirin Village in Muaro Jambi Regency and Tanah Grow Village in Bungo Regency.
