Abstract

Manual Materials Handling (MMH) activities still widely used in a job. This is because in this activity has a high flexibility, inexpensive, and easy to apply. However, these activities also constitute a risk when applied to the inadequate  environment, less support of tool, and bad posture of work. Therefore, measurement of safety limit in doing the job by using a calculation based on the equation of NIOSH Lifting Index. The case study at PT. Central protein Prima Surabaya is the removal of shrimp feed bag that still use manual way. Acquisition of STRWL calculation results obtained for the removal of shrimp feed bag stacks 1, 2, 3, 4, 5, 6, and 7 from 5,003 Kg to 67,41 Kg. Actual load which worker must lifted in this case study on a pile of 1 to 7 is 25 kg. Load  is lifted for the removal of shrimp feed bag bigger than STRWLmake it not feasible. CLI obtained in shrimp feed bag removal activity is 6.041 which value exceeds 3. Therefore CLI in this case study may create a risk of spinal cord injuries and to do their job changes. By measuring the changes in safety limits and do the work, expected reduced risk of injury to workers. After measuring the safe limit for the removal of bag obtained load is lifted workers have the risk of spinal injury, so it is given recommendations for improvement is by doing a redesign on a conveyor in the form of additional elevation (vertical) 57 cm at the end of the conveyor, as well as shortening the horizontal distance between the worker's body with a bag of shrimp feed time of transfer. With these recommendations obtained a decrease CLI becomes 1.795, which means that the risk of injury is between 1 <CLI ≤ 3 and can be reduced.

Abstract

Time is one of the factors to assess a worker's performance in utilizing the available resources. Operator in his work requires efficient time to improve work productivity. One of factory in produce a shrimp feed in Surabaya has a large production level. In the production process, the packaging department in this company still uses human resources in their production process and the company define the standard of production without using standard time. This paper investigates the opportunity a logical analysis in determining the standard time in this company. The determination of the standard time in the packaging process requires comprehensive analysis. Objects observed are four operators in the packaging department that carried out the activities of filling bag the shrimp feed with 40 replication for each data. The work measurement was conducted by direct method using Stopwatch Time Study (STS) with snap-back method. The results of this study indicate the standard time value of the four lines packaging is not much different or almost the same. Sequentially the standard time workers line 1 to line 4 is 7.325 seconds, 7.240 seconds, 7.225 seconds, and 7.065 seconds. Allowance used for workers is 8%. However, the existing production rate of company is higher than the production rate of work measurement calculation. This is due to the difference of definition in employee allowance rate and performance rating.
