【 摘 要 】

The purpose of this research is to analyze whether fuzzy mamdani method can be used to deterMine roasting time in roasting coffee process. Coffee roasting process is one of the important stages in coffee processing, because in the roasting process will deterMine the aroma of coffee taste. In the roasting process there is often an error in deterMining the duration of roasting. Improper roasting process will cause the taste of coffee is not as expected. The variables used in the roasting process include temperature, density, water content of coffee, number of copies, size of fire, and time. Since the value of each variable is unclear or uncertain, a fuzzy logic method is needed to solve this problem. Every variable used in the fuzzy method will be deterMined its fuzzy set. Observation was done by using temperature data 1100C density 700 gram, water content 13%, quantity 1300 gram, and fire size 500C, from observation data got roasting time 10,19 Minute, where time data have match with set fuzzy made. The results show that the proposed fuzzy mamdani method can be used as a decision system in deterMining coffee roasting time.
