<![CDATA[Research is an activity to obtain a solution to a problem or phenomenon that occurs through scientific steps. To understand research, researchers must first understand what statistics are. Statistics is a science that studies the methods of collecting, processing, interpreting and drawing conclusions from the data collected or obtained. Therefore, statistics is said to be one of the sciences that is indispensable in research, not least in the field of mathematics education because statistics are used to identify and describe the relationships obtained from the data that has been collected and then processed to obtain a conclusion. The role of statistics has been seen from before the research was carried out, the research took place until the processing of research results.]]>

<![CDATA[At this time the type of crop that is most often planted is corn because it is a plant that is easier to grow than other secondary crops and the cost is also relatively less and the process is not complicated. The profit from the harvest depends on the selling price and the capital used. So that there is uncertainty in determining the profits of the farmer. Given the uncertainty, it is necessary to optimize the selling price. To optimize the selling price, fuzzy logic can be used. Fuzzy Mamdani is a method that is very flexible and has tolerance for existing data or is usually referred to as secondary data. The data obtained is data collected from Uluan District which is known by the local government in Uluan District. Where the data is data from the community in each village starting for 12 periods of planting corn. By using the Mamdani method, the optimum selling price in the first period of 2012 was Rp. 2,644,-.]]>
