Abstract

The company uses the Gantt Chart method for scheduling planning, but this method has several disadvantages, that is, it cannot explicitly indicate the relationship between activities and how one activity results in other activities if the time is late or accelerated. To determine the optimal duration and the total cost of building 1 (one) Crude Storage Tank capacity of 600 MB (Mega Barrel) an optimization of the duration of the project is needed so that it can be known how long a project is completed and looking for possible acceleration of project time using the Critical method Path Method is a method used to make project scheduling. By using the Critical Path Method method the work of building 1 (one) Crude Storage Tank with a capacity of 600 MB (Mega Barrel) on the Open Access (Phase-1) RU-II Dumai project, can be completed within a period of 384 days/64 weeks, and trajectory critical lies in the b-c-d-e-f-j-l activity with a total cost of Rp.15,086,074,328.

Abstract

Loss on a working system is one of the causes of the cost of the process to swell. The loss that reaches more than 450 tons/month on a cooling water system at a chemical company in the Serang area causes the company's expenses to swell. This study aims to determine the cause of cooling water wash as a basis for process improvement by using Six Sigma and Failure Mode Effect Analysis (FMEA). Data analysis results showed that cooling water loss is too little backwash filter duration, service filter duration is not optimum, and flow unreadable side stream. Improvements by increasing the length of the backwash, raising the service time of the sand filter to every two days, and cleaning the rotameter can increase the sigma value from 3.5 to 4.5.
