Design and Simulation of a Gambir Press Machine with Hydraulic and Screw Press System, Capacity 100 kg per Hour

This study aims to design and simulate a gambir press machine utilizing a hydraulic system and a screw press with a capacity of 100 kg per hour to enhance production efficiency. The design process is conducted using CAD/SolidWorks software. The design calculations include production capacity, hydraulic pressing force, and drive motor power. Simulation results indicate that the hydraulic system provides uniform pressure distribution of up to 94%, while the screw press increases extraction efficiency by up to 86%. Prototype testing demonstrates that the machine operates with an extraction efficiency of 95% while maintaining optimal power consumption. This machine is expected to improve the productivity of gambir farmers through a more efficient design and easier operation.
