Manual Material Handling

Manual material handling is one of work activities that have an effect on the physical aspect of workers in manufacturing industry, it is necessary to do the analysis of the risks from such activities. Analysis was performed on worker when performing manual lifting activity and when using two tools (Automatic Handlift and Manual Handlift). In addition to analyse in ergonomics aspect, time study analysis and productivity measurement were carried out to determine the effects of the equipment. Nordic Body Map (NBM) questionnaire on worker using Automatic Handlift showed declining level of musculoskeletal disorders by 22%. REBA method obtained score of 10 and was declined to 4 after using these tool. The results of MPL method showed declining of Fc value from 4756.37 N to 1346.56 N. The results of RWL method showed declining of LI value (Lifting Index) origin and destination from 1.84 and 1.18 to 1.12 and 0.89 respectively. As for worker using Manual Handlift, NBM questionnaire result shows declining level of musculoskeletal disorders by 57%. REBA method obtained scores of 8 and was reduced to 5. For MPL methode result, the Fc value is 4906.99 N and reduced to 2047.88 N. RWL method results showed declining of LI value (Lifting Index) origin and destination from 1.02 and 0.67 to 0.74 and 0.58. The results of time study analysis showed declining of Standard Time when use the two tools and make the increasing productivity of 9% by worker using Automatic Hadlift and 4% by worker using Manual Handlift.

Introduction: Manual Material Handling tasks can cause fatigue in the short term and increase physical workload and musculoskeletal injuries in the long term. The present study was conducted to determine the amount of forces entered to the lower back in workers with manual material handling tasks.Methods: This descriptive-analytic study was conducted on 100 workers in food industries in Malard city in 2017. The Nordic questionnaire was used to determine the frequency of musculoskeletal disorders. The 3DSSPP was also applied to determine the amount of forces entered to the lower back of manual material handling tasks workers. Data analysis was conducted using SPSS (version 23)Results: we found that 24percent of workers had discomfort in at least one of their nine musculoskeletal muscles. The results of 3DSSPP showed that 30 and 34 percent of the compressive forces entered into L5/S1 and L4/L5 discs, respectively. In addition, the shearing force loaded on the L5/S1 disc was also found to be higher than the permissible limit eight percent of the participants. No significant relationship was found between the frequency of musculoskeletal disorders and the amount of compressive and shear forces entered to the lower back of workers.Conclusion: Based on NIOSH  recommended limits, the amount of compressive and shear forces entered to the lower back in 3DSSPP showed that in 30 percent of manual lifting load tasks, the risk of injury to the lower back was moderate and this risk was low in 70 percent of tasks.

Time Required

The productivity of any organization can be increased by optimizing the work process. Low productivity of workers is one of the reason behind the delay in delivery in manufacturing sector we know that in manufacturing sector labor is prominent thing. Improving the productivity means to make the best possible use of available resources and achieve maximum output. This paper focuses on the productivity of machine as well as labor by using fixtures, updated systematic layout and use of material handling equipment. This paper also covers the, what is productivity, which factors are affecting on productivity and efficiency. Maximum efficiency or productivity is trademark of any successful organization The objective of this paper is to identify the problem in medium scale industry due to time and effort required for any operations is high To tackle and understand a detailed analysis regarding processes using time study and work study. Due to implementation of all the measures the productivity of an organization is increases resulting in reduced effort and time required for operation and all operations done optimally.

The following study deals with the detailed reviews regarding the interventions that have been done globally in the sector of entrepreneurial interventions in aspect of work simplification. Various standards hence can be considered while referring to different designs for enterprises, especially small scale enterprises. The studies have revealed the musculoskeletal disorders from manual material handling (MMH) works often involving strains and sprains to the lower back, shoulders, and upper limbs. The ergonomic interventions are found to give comfort to the workers in various postures. It is concluded that the design of the system must be incorporating to the worker, equipment, and environment as a whole.

Penggunaan tenaga manusia sebagai sumber tenaga kerja memiliki resiko terjadinya cidera pada tulang belakang. Fleksibilitas gerakan merupakan satu-satunya alasan industri masih memanfaatkan tenaga manusia dalam penanganan material secara manual. Berdasarkan hasil kuisioner Nordic Body Map (NBM) pada 2 orang responden di UKM. Sederhana, yaitu responden pertama menunjukan scoring NBM sebesar 43, yang artinya masuk dalam kategori tinggi dan perlu dilakukan perbaikan segera. Pada responden kedua menunjukan nilai skoring NBM sebesar 38 yang artinya masuk dalam kategori sedang dan mungkin perlu dilakukan perbaikan. Dari hasil analisis kuisioner tersebut, apabila responden bekerja dengan durasi waktu yang lama dan repatitif, kondisi ini akan beresiko terjadinya gangguan sistem musculoskeletal disorders (MSDs) yang berakibat pada masalah back injuries yakni cedera karena adanya gaya tekan pada tulang belakang. Penelitian menggunakan metode NIOSH yang terdiri dari perhitungan MPL (Maximum Permissible Limit) dan RWL (Recommended Weight Limit) pada 2 orang responden di UKM sederhana, sehingga diperoleh hasil yaitu pada responden I terjadi gaya tekan pada segmen L5/S1 sebesar 1907,625 N dan responden II sebesar 1331,843 N dan kemudian berat beban angkat yang direkomendasikan untuk kedua responden tersebut adalah tidak lebih dari 3,763 kg untuk responden I dan tidak lebih dari 3,90 kg untuk responden II.

Workload related to material handling is one of main biomechanical risks that cause work related musculoskeletal disorderat work. The aim of this study wasto assess the risk factors for biomechanical loading present at carried out tasks by port stevedores. First, we made a diagnosis using the risk assessment matrix (RAM) then; we evaluated the biomechanical risk using the NIOSH lifting equation (Compound method). The results were a high level of unacceptable risk at the beginning and at the end of the task (scored 4.22 and 8.50 respectively). Subsequently, we made a correlation analysis between this scored and the musculoskeletal discomfort perceived by stevedores. From this analysis, it is evident that there is a direct relation between lifting vertical distance, trunk torsion, and the increase of musculoskeletal lesions suffered by the dockers. Finally, we proposed some methods to improve the activities of filling and emptying containers and minimize the manual material handling.

<span lang="EN">Production results that are handled manually are lifting the burden of jerry cans weighing 24 kg from the conveyor to the pallet. This removal process is risky for musculoceletal and can cause lower back pain. The appointment process takes place in the packing line section D. The purpose of this study is to determine the level of risk, find out the form of conveyor in accordance with working conditions and provide recommendations for corrective actions to be taken when the operator's work attitude has the risk of injury. The assessment of work posture is based on the assessment of RULA for each part (upper arm, forearm, wrist, wrist rotation, back, neck, and leg position) which are then categorized based on the results of the grand score on the action level indicating that the posture is required repair or not. The results of this study found that 3 workers for the grand score of work posture an average of 7 which indicates the need for action now. This is influenced by heavy loads with manual lifting</span>.
