Design of work equipment for strength test (Drop Test) of 50kg sugar sack packaging as QC incoming packaging with ergonomic & risk approach at PT Medan Sugar Industry

Abstrak

In the context of the crystal sugar industry, the assessment of the packaging integrity of 50-kilogram sugar sacks remains predominantly reliant on manual methodologies. These conventional approaches, however, are not without their inherent risks, particularly with respect to the safety of the laborers and the efficiency of the testing process. The objective of this study is to design a semi-automatic drop test tool that is ergonomically designed, safe, and efficient. The design process will utilize a Human Centered Design (HCD) approach, work risk analysis using the Ergonomic Assessment Checklist (EAC), and Acceptable Quality Limit (AQL) statistical sampling method. The analysis indicated that conventional methods are associated with a significant risk of musculoskeletal injury. The development of a semi-automatic drop test tool was informed by a comprehensive identification of user needs and a detailed simulation of work postures. This tool is equipped with a remote operating system and height adjustment, allowing for adaptation to the operator's posture. The findings of this study offer several practical advantages, including enhanced efficiency, safety, and testing accuracy, as well as a reduction in long-term expenditures. The novelty of this research lies in the integration of three approaches (HCD-EAC-AQL) within a unified industrial equipment design framework. The final evaluation demonstrated a 70% reduction in occupational risk and an enhancement in the efficiency of the packaging quality test process. The findings of this study can serve as a valuable reference point for the development of analogous testing equipment in diverse industrial sectors.
