Design of Brick Lifting Aids Based on Anthropometric Data to Reduce Physical Complaints in the Production Process at UD Jaya Usaha

Abstract

This study aims to design an ergonomic lifting aid tool based on anthropometric measurements to reduce physical complaints experienced by workers during the batako (concrete brick) lifting process at UD Jaya Usaha. Preliminary observations and interviews with company owners revealed frequent complaints of pain in the lower neck, waist, and both arms due to manual lifting activities. The research method includes direct field observation, anthropometric data collection, and analysis using data adequacy and uniformity tests. The design process refers to ergonomic principles and utilizes key anthropometric dimensions to ensure the lifting tool suits the workers' body posture and comfort. Results show that the proposed tool effectively reduces physical strain and categorizes the lifting activity as safe. The company is advised to implement the designed tool and re-evaluate its current work posture policy to improve worker health and performance.
