<![CDATA[Arabica coffee (Coffea arabica L.) is a coffee with the best taste compared to other types of coffee. The most ideal altitude for cultivating Arabica coffee is between 1200 mdpl -1400 mdpl, but Arabica coffee grows and produces well at an altitude of 900 mdpl - 1700 mdpl which is an ideal habitat for cultivating Arabica coffee. If Arabica coffee is planted in the lowlands, especially at an altitude of 600 - 700 mdpl, usually the production and quality are low and susceptible to leaf rust disease. This study aims to analyze the characteristics of the physicochemical properties, namely reducing sugar, extract content and caffeine content of Gayo Arabica coffee at an altitude of 1500 mdpl and 1600 mdpl. This study uses the Completely Randomized Design (CRD) Non-Factorial method with 2 levels of altitude treatment, namely 1500 mdpl and 1600 mdpl with 4 replications. The results of this study indicate that an altitude of 1500 mdpl has an average of 43.49013% and 1600 mdpl has an average of 51.10553% significantly affecting the coffee extract content. At an altitude of 1500 mdpl, it has an average of 0.3504% and 1600 mdpl has an average of 0.3792% which has no significant effect on coffee reducing sugar. At an altitude of 1500 mdpl, it has an average of 0.74625% and 1600 mdpl has an average of 0.5095% which has a very significant effect on coffee caffeine content.]]>
