Abstract

A apparatus has been developed to press leaves of a plant called Uncaria Gambir Roxburgh by using the hydraulic power in order to obtain the paste from the leaves. Aim of the research is to design and fabricate the equipment getting the Gambir with high quality. High quality of Gambir depend strongly on content of catechin. The higher the content of catechin in Gambir the higher the quality of gambir. The meaning of Gambir is draied extraction of Gambir leaves. The capacity of hydraulic power developed was designed on maximum 250 bar. The pressure on leaf surface achieves 16 bar. The temparatur of leaves was set up on 90oC. The result of the investigation shows that the apparatus can produce the paste of Gambir. Dried extraction of Gambir can be obtained up to 8%. Keywords: Hidrolik, Catechin, Gambir, Dehumidifier and Pressure
