Abstract:

PT. Ujong Neubok Dalam (UND) is a company engaged in oil palm plantations and processing of Crude Palm Oil (CPO) and Kernel Palm Oil (PKO). In carrying out its production, the company has various variations of machines that are used to facilitate the production process, one of which is a screw press machine. A screw press is a machine used to chop and crush palm fruit to produce palm oil and separate oil from shells, nuts, and fibers. Screw press machines in CPO production have a very important role because if the screw press machine experiences insufficient pressure, it will affect the qualit

Briquettes are formed right where they are made, thus reducing air pollution. In this work, a sawdust and coffee husk briquetting machine is redesigned and built. In this work, briquettes (solid fuels) were made using a screw-type briquetting to compress sawdust and coffee husk at different ratios.

Abstract:

The screw press is a type of machine press used for extracting crude palm oil from the oil palm’s mesocarp, where its short driveshaft, a mechanical component for transmitting torque and rotation, is often found to be susceptible to failure. Since the initial damage to the short driveshafts in the shaft keyway area is associated with the frequent incidence of shaft failure, this research aimed to discover the root cause of this failure and how to prevent it using visual inspection and stress analysis methods as well as those of the fractography, metallography, chemical composition, and hardnes
