The research objective is to study coffee skin as fuel to dry coffee seeds by using tray drier at several direct and indirect heatings and coffee seed pile heights on fuel requirement per weight of dried coffee seeds and drying rate. This study was conducted at Farm Machinery and Equipment Laboratory, Agricultural Technology Department, Faculty of Agriculture, Sriwijaya University, Indralaya from March 2012 up to March 2013. The method used m this study was Randomized Block Design with two treatment factors consisting of direct and indirect heatings and coffee seed pile heights. Each factor had three levels and replicated three times. The first treatment was direct and indirect heatings, whereas the second treatment was coffee seed pile heights consisting of 1 cm, 2 cm and 3 cm. The observed parameters were fuel requirement per weight of dried coffee seeds, drying rate, relationship between drying time and fuel requirement per weight of dried coffee seeds, drying efficiency and fuel utilization efficiency. The results showed that the highest fuel requirement per weight of dried coffee seeds was found at (P2T3) treatment consisting of indirect heatings and 3 coffee seed pile height of 1.40 kg/kg, whereas the lowest one was found at (PjTi) treatment consisting of direct heating and 1 cm coffee seed pile height of 1.26 kg/kg. cm The highest drying rate was found at (P1T1) treatment of 0.47 kg/hour and the lowest drying rate was found at (P2T3) treatment of 0.33 kg/hour. The highest drying efficiency was found at direct heating treatment of 52.07 % and the lowest was found at indirect heating of 40.05%, whereas efficiency of fuel utilization was 82.06 %. The lowest requirement per weight of dried coffee seeds and the highest drying rate was found at (P1T1) treatment of 1.26 kg/kg and 0.47 kg/hour, respectively. The fuel utilization efficiency was 82.06 % and the highest drying efficiency was 52.07 %.
