Abstract

This study was conducted at Subsea Sdn Bhd, Sepang. This company was established in 2007 and it main business is to supply steel products to large corporation particularly in the field of oil and gas (0 & G) and construction. One of the company's main products is Tenaga Nasional Berhad (TNB) hot-dip galvanized concrete pole accessories. There are 17 types of pole accessories that are being produced by Subsea Sdn Bhd which include J hook, bracket D, triangular bracket and band U 1OM. This study focused mainly on four products. This company recently established the cycle time and standard time for the manufacturing of the product in order to determine the production target. The calculation of the standard time was based on a constant fatigue allowance, 30%. This 30% of allowance has become a common practice in this company. Fatigue allowance is the adjustment done to cycle time to obtain the standard time for the purpose to recover the loss time due to personnel need and fatigue. By providing small increase to the cycle time, the workers still able to cover loss time and complete the work assign to him/her. In this study, a new standard time for the manufacturing of products was proposed in order to achieve more accurate production target. The calculation of the new standard time incorporated fatigue allowance that is proposed by International Labour Organization (ILO). The fatigue allowances include personnel allowance, standby allowance, abnormal position, noise level and atmospheric condition. Each of the allowance is rated by numerical value, 1, 2 and so on. Stopwatch was used to record the cycle time. Then, the standard time was calculated by dividing the average cycle time to the allowance base on the ILO rating scheme. The results show that the new fatigue allowance were range from 25% to 35% as compared to the constant 30% of the existing allowance adopted by the company. The new standard time result in the increase of production target for manufacturing product with less labour demands while reducing the production target of more labour intensive product. It also became apparent from this study that the production target increases by about 10% to 15% based on this new standard time. The newly established standard time apparently provides a guideline to the company especially to set daily production target that is more realistic and labour-oriented. The production target also could be adopted as a basis for a fairer productivity-linked incentive scheme that is being developed by the company.
