Abstract

Fresh fruit bunches (FFB) loaders using manual handling tools like loading spikes indirectly leads to repetitive awkward posture including lifting, bending, and swinging. This study explained the experiences of the workers on the loading activities using the interview or questionnaire by analyzing body posture and part of the body that felt discomfort while doing the loading process by lifting the FFB weighted around 1 to 30 kg into the 6 to 7 feet truck. The data recorded was used to suggest mechanisms to aid the workers in improving body posture. This study assessed from CATIA V5 software regarding the working postures that focused on the loaders between the current work posture and ergonomically safe posture by using Rapid Upper Limb Assessment, RULA. From RULA analysis, the left and right arms as well as the wrist part of the workers were identified as the most severe. According to the NIOSH lifting, equation test resulted that the RWL and LI are at a very dangerous level where the lifting index reached 6.49. Apparently, the implementation of the suggested mechanism called slide concept conveyer as well-known as inclined conveyer significantly contributed to the workers' mainly on the affected part of the body which improved as recorded in the RULA assessment. On the other hand, the new NIOSH lifting equation recorded a lifting index value of 1.10 with RWL attaining a value of 13.68 Kg compared to the previous LI value which exceeds 1 and low recommend weight limit, RWL that reached only 2.31 kg. The findings from this study provide a crucial basis for further research including completing additional analyses like REBA or proceeding to the fabrication stage by concentrating on the proper design considerations and technical elements.
