Abstract

The electric road sweeper developed by the Mechanical Engineering Department of the Gadjah Mada University Vocational School can handle waste management problems. To improve sweeper performance, several changes are still required in the unit, especially in the sweeper vessel section. In an effort to improve sweeper performance, vessel design is needed. Design and performance analysis of vessels using Autodesk Inventor software. In this research, the addition and replacement of hydraulic cylinder types was carried out to make it a transport vehicle. Apart from that, the use of lighter materials also reduces the weight of the vessel from 650 kg to 278.95 kg. The simulation results show that all vessel sweeper components have a safety factor above one, indicating that they are safe to use. Apart from that, this design is able to withstand loads of up to 4900 N without exceeding the yield strength limit of the material used by the vessel. The maximum inclination of the sweeper vessel is 30.4 degrees. Hydraulic cylinder testing shows an extend speed of 11.77 m/s and a retract speed of 7.9 m/s. Under 100 kg load conditions, the extend speed becomes 12.49 m/s and the retract becomes 8.39 m/s, the retract movement is faster due to gravity.

Abstract

Occupational health and safety, especially in heavy equipment projects, is very important to avoid work accidents. In the field of construction and mining, work accidents that are often experienced are usually run over, and hit. Most of these accidents are caused by operator or human negligence factors, as well as factors from machines or tools. On the hydraulic excavator there is a swing movement, this movement has the potential to cause work accidents such as hitting an object in the swing area because the object is in blind spots that cannot be measured and seen by the operator. In this study, the authors designed a tool that functions as a warning system and monitoring for detecting swing motion obstacles in the swing area to avoid the accident, while testing the performance of the system that has been created. The design of this tool uses an ultrasonic sensor HC SR-04 which is able to detect an object with ultrasonic waves, LCD 1602 as a monitoring tool for the distance between the sensor and the object that blocks the swing motion, and with the addition of a buzzer as a warning system that will sound at a certain distance. Thus the operator can anticipate if there are objects that block the swing motion. The overall test results of the system that has been created show that the front section obtained a test success rate of 84% with a standard deviation of 0.3116, and the back section obtained a test success rate of 86% with a standard deviation of 0.2916.
