Abstract

The problem that occurs at this time is that the production process is often hampered and does not reach the set targets because the Rolling Stand 3 (mill section) machines are often damaged. Rolling Stand 3 machine (section mill) is used to form steel with a grinding process (rolling). The study was conducted using the Overall Equipment Effectiveness (OEE) method where Overall Equipment Effectiveness (OEE) is a systematic method for measuring the level of machine effectiveness. Overall Equipment Effectiveness (OEE) calculations can be gauged from actual data related to Availability, Performance Rate, and Quality Rate. Overall Equipment Effectiveness (OEE) is used as an indicator, to find out the causes of machine ineffectiveness done by calculating Six Big Losses to find out what factors influence the Six Big Losses. Based on the research results for the period January - December 2015 on Rolling Stand 3 (mill section) machines, the Availability value was 55.77%, Performance Rate 60.05%, Quality Rate 97.82% and Overall Equipment Effectiveness (OEE) was 32.86 %, meaning Overall Equipment Effectiveness (OEE) below the standard value for world-class, which is 85%. To maximize overall machine effectiveness, improvements are needed to the factors that influence the low amount of Overall Equipment Effectiveness (OEE). When viewed from the six elements Six Big Losses, the greatest value is found in the Equipment Failure factor.

Abstract

The problem that often occurs in manufacturing companies is that companies sometimes experience delays in project completion. One of the factors that caused delays was that the company still randomly carried out any activities that took precedence over the process. With these problems, causing losses that are not good for both the implementer and the project owner. This will also have a negative impact on the company, including worsening the image of companies that seem unable to complete the project according to the agreed contract. This study aims to determine which activities in the critical path for initial conditions and acceleration, to know the difference in processing time from the initial conditions and the acceleration conditions, to know the difference in processing time from the initial conditions and the acceleration conditions, and to know the benefits of project costs which occurs between initial conditions and conditions after acceleration. This study uses the Critical Path Method method to determine the determination of the schedule and the estimated time is deterministic / definite and determine which activities are considered critical paths with the duration of this project for 192 working days. Based on the results of research critical activities in the initial conditions with 192 days. While for acceleration conditions, the completion time is 182 days with 2 critical trajectories which includes 17 production activities which all activities enter critical crossings. The optimal duration of the project is 182 days with a total project cost of Rp.900,000,000 on the alternative to adding overtime hours.
