An Uncontrollable Maize price fluctuation can harm farmers when the price changes in the level of consumer price and it is not followed at the level of the producers. This study used monthly prices data during 2009-2016 in East Java province. Methods of analysis used, are in the form of price variations and market integration analysis. The results of the prices variation analysis are maize prices that gained at the level of the producers, wholesalers, and consumers are low fluctuating, but the results of the market integration show that between the producer price and consumer price, between the producer price and the wholesale price, and between wholesale prices and consumer prices are integrated in the short term and are not integrated in the long term, this indicates that the price of maize markets information systems had not been running perfectly. So, the Government needs to fix the system to make the price information of maize can be well-integrated.
