Abstract

In the industrial world, machines are widely used to facilitate a more effective and efficient way of working, by trying to abandon old work patterns that rely heavily on human labor along with the development of industrial technology 4.0 in observations made by researchers at household MSMEs in the snack food industry, in Titi Village Payung, Air Putih District, Batu Bara Regency. Processors of cassava and banana chips still use human power and use simple tools. The process of chopping cassava and banana chips is not done at a table, but is done directly on the floor. The chopping process in this condition causes an uncomfortable working position for the worker, because it is done with a bent back position, the head is always bowed and the legs are always bent. . This chopping process is usually carried out for 8 hours per day. The cassava and banana chopper tool at the research site's MSMEs has dimensions of 30 cm long, 15 cm wide and 21 cm high. On this basis, researchers consider it necessary to minimize the obstacles faced by cassava and banana chip managers, by making a cassava and banana chopping machine. The performance test results of the cassava and banana chopping machine obtained 1 kg of cassava and banana slices in 1 minute or the same as 60 kg in 60 minutes, with the resulting cassava and banana slices having a thickness of 1 - 2 mm. This cassava and banana chopping machine has been made to be more practical to use and can compete with domestically made products.

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.
