Abstract

Excavators is one of the heavy equipment used to do transport, excavation, loading work that is operated using hydraulic energy. Excavator construction consists of three main parts, which consist of undercarriage, upper structure, and front attachment. During operation, one of the front attachment parts that has the highest performance is the boom cylinder actuator because it carries the entire load of the front attachment activity. The continuous work of the hydraulic boom cylinder will definitely suffer damage that cannot be avoided and can interfere with the performance of the unit. The damage is in the form of external leaks, internal leaks, scratches, and wear. This research aims to identify the types of damage, causal factors, and impacts caused by boom cylinder damage, explain the boom cylinder maintenance system and process, identify bends in the cylinder rod, and provide a reference price for repairing the Hitachi excavator boom cylinder. The methods used in this research are literature study, observation, and interviews. The results indicate that damage can be minimized by performing scheduled maintenance, such as selecting and replacing the right hydraulic oil and grease, cleaning the hydraulic oil cooler every 500 hours, replacing the oil filter every 250 hours according to the maintenance schedule, performing the inspection process during daily checks, operating the unit in the right way, avoiding modifications that can cause overloading, and performing oil analysis every 250 hours to ensure high availability of the unit as planned.

Abstract

Small and medium-sized meat processing industries (SMEs) face challenges in shredding duck meat, which has dense and coarse muscle fibers. This Community Service project aims to design a shredding machine based on a pulley transmission that is efficient, hygienic, and meets the needs of SMEs. The method used is Community Service engineering (R&D) with a prototype design approach, performance testing, and analysis of power consumption and shredded results. Data was obtained through direct observation and testing in Marihat Jaya Village in Pematangsiantar City. The results show that the machine is capable of shredding up to 5 kg/minute with a power consumption of 1.3 kW and producing uniform shreds. This machine has proven to be effective, safe, and worthy of being developed as an appropriate technology for local food SMEs.
