Abstract

The research objective was to study the effect of decaffeination of robusta coffee based on maturity level and size diameter. This research was conducted at Segamit Village, Semendo Districts, The Laboratory of Biosystem and Laboratory of Chemistry on Agriculture, Faculty of Agriculture, Sriwijaya University, on September 2018 to July 2019. This research used Completely Randomized Design Arrangend in Factorial (RALF) with two factors. The first factor was the maturity of robusta coffee (red, yellowish red and green). The second factor was diameter of robusta coffee according to SNI number 01-2907-2008 (big, medium and small). The parameters on this research are measured rendemen, moisture content, caffeine content, ash content, lipids content, protein content and carbohydrate content. The result showed that the difference of maturity level coffee bean and diameter size coffee bean affect the yield, water content, ash content, lipids content, protein content and carbohydrate content. The combination of interaction of maturity level coffee bean and diameter size coffee bean significantly affected the yield, water content, ash content, lipids content, protein content and carbohydrate content. The best treatment of caffeine value is A3B3 1.25%, the best treatment yield content is A1B1 91.5%, the best treatment water content A1B1 3.23%, the best treatment ash content A3B2 4.61%, the best treatment protein content is A1B1 9.59%, the best treatment lipids contens A2B3 6.72% and the best treatment carbohydrate content is A2B3 76.08%.
