Abstract
Indonesia is one of the fourth largest coffee producers in the world. Arabica and Robusta coffee are types of coffee that are quite widely grown in Indonesia. Both types of coffee are partly grown organically; namely coffee whose entire cultivation process does not involve chemicals such as pesticides or fertilizers derived from chemicals. Organic coffee can be processed into coffee that has a distinctive taste. The coffee processing process is now very modern and has various processes and stages. The coffee processing process is also influenced by the characteristics of each coffee company, wet and dry processes. One method of processing coffee is through a fermentation process by adding bio ghally. To mix the solution, a mixer is needed. Coffee bean mixing equipment with bio ghally liquid fermentation liquid is a tool in the stages of the coffee bean processing process to assist the process of mixing and wetting coffee beans with bio ghally liquid prior to the fermentation stage. The purpose of this research is to design and manufacture a coffee bean mixer of bio ghally fermented solution. This tool is designed to mix coffee beans with fermented liquid with a capacity of 25 kg and within 15 minutes. Machine parts include the frame, hoper, mixing tube, drive motor and transmission. The results of the testing process for this coffee bean mixer show that the process of mixing 25 kg of coffee beans took 15, 17 minutes.
