Arabica coffee (Coffea arabica) becomes one of the most in-demand types by the community due to its typical taste. The material needed in this study was Gayo Arabica coffee (full wash) obtained from farmers in Bener Meriah, Aceh Province of Indonesia and specially ordered. The right method and coffee brewing device are needed to obtain this typical taste of coffee. One of the coffee brewing methods that keeps developing until now is the manual brewing method. This study aims to find the sensory assessment of Gayo Arabica coffee taste in various varieties with manual brewing devices by using Analytical Hierarchy Process (AHP) method. Manual brewing devices used were Vietnam Drip, French Press, V60, Eva Solo, and Filter, while the chosen va rieties are Tim-tim (Gayo 1), Bor-bor (Gayo 2), and P88. The study result showed that based on the preference of product acceptance by the panelists, the most chosen criteria of taste sensory were flavor (0.253), followed by aftertaste (0.222), sweetness (0204), acidity (0.165), and body (0.155). The variety chosen as the best variety with manual brewing was Tim-tim in various manual brewing devices, which are V60 (0.156), French Press (0146), and Eva Solo (0.140). The next alternatives brewing devices were Vietnam Drip (0.127) and Filter (0.109). Thus, it could be concluded that flavor is the top priority that influences Gayo Arabica coffee’s taste. Therefore, Tim-tim with manual brewing devices (V60, French Press, and Eva Solo) is preferred over other varieties in this study. This finding also becomes a recommendation that the variety for the best serving of Gayo Arabica coffee brew with the most preferred taste with manual brewing devices is Tim-tim.

Gayo Arabica coffee is a famous specialty coffee in Indonesia and abroad. Proper roasting is needed to produce high-quality coffee, including getting the desired coffee taste. This study contributes to roasting high-quality coffee, especially regarding the appropriate time variation in the drying phase. This study aims to analyze the roasting time of Gayo Arabica coffee in the drying phase based on the cupping score and sensory assessment. Coffee roasting in this study was carried out by modifying the time in the drying phase for 3:00, 4:00, and 5:00 minutes, while in the other phases (maillard and development), it was 4:00 and 3:00 minutes, respectively. The study parameters include roasting charts, roasting profiles, cupping scores by certified panelists (Q graders) and sensory assessments by panelists identified by the TOPSIS method. The TOPSIS is a decision-making method based on various alternatives that are ranked to get the best results with the highest value. The results showed that the best time treatment in the drying phase based on the cupping score was the F2 treatment as rank 1 (score 85.00), treatment F1 as rank 2 (score 83.50), and treatment F3 as rank 3 (score 81.00). Meanwhile, the sensory assessment by the panelists using the TOPSIS method showed the same thing for rank 1, namely the F2 treatment with a value of 0.88. However, it is different for rank 2, namely the F3 treatment with a value of 0.69 and ranks 3 is the F1 treatment with a value of 0.17. It can be concluded that the assessment by certified and identified panelists, who can be considered representative of consumers, show the same conclusion that coffee roasted with the best treatment in the drying phase is 4 minutes (F2).
