The purpose of this study is to identify, review, analyze and describe various macroeconomic factors such as land area, investment, infrastructure, total production and inflation that affect the productivity of oil palm plantations in North Sumatra province. The research method used is the multiple regression method with the error correction model. This model is used to see that the relationship in the short term is with economic theory and in its solution to the variables of time series that are not stationary in the level and the regression of gradual decrease. From this analysis we will obtain a short-term regression equation towards the long-term equilibrium. The type of data used is secondary data. The results of the investigation show that land area, investment, infrastructure, total production and inflation simultaneously have a significant effect, while the area of land, investment, infrastructure, total production partially has a significant and positive effect, and Inflation has a significant and negative effect on the productivity of oil palm plantations in the north sumatra province in the short and long term balance. Keywords: land area, investment, infrastructure, total production, inflation, palm oil productivityReferences
