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

In construction activities do not escape from operations on iron, in iron activities cannot be separated from work accidents that often occur. As with work accidents that occur in reinforcing iron manufacturing activities, it is necessary to make further identification to determine the potential for workplace accidents that have not been identified before. Therefore, researchers are interested in identifying further the potential for whatever might occur in reinforcing iron activities, using the Hazard Identification Risk Assessment and Risk Control (HIRARC) method. HIRARC is a method used to identify, then provide a hazard assessment and control potential workplace accidents in work activities that are being carried out. This research is qualitative research. The purpose of this study was to find out the dominant factors of work accidents in reinforcing iron activities in the Pakupatan-Palima road construction project and to find out the appropriate control proposals to reduce the risk of occupational hazards and provide proper controls to reduce the risk of occupational hazards. In this study, researchers used the HIRARC method. The technique used in data collection is field observation, and interviews. Data analysis begins with calculating the risk value with a score. Based on the results of the study, it is known that there are six types of jobs obtained by the percentage of 30.8% for potential low, 61.5% for likely medium and 7.7% for likely high. To find the root causes and dominant factors of work accidents, researchers using the root cause analysis (RCA) method found that the dominant elements of work accidents in manufacturing activities were factors in human habits that did not use PPE.

Abstract

This development poses a challenge to fulfill it by increasing the ability to provide or produce it. These conditions require companies to try to make their products available according to consumer needs. So the company should impose a system of Safety Stock, and ROP (Re-Order Point) or a message back point to ensure the availability of raw materials and the way of production. But sometimes the company doesn't pay attention to the lot size inventory efficiency issue. As a result, manufacturing companies tend to make large purchases without regard to the costs incurred. The purpose of this study is to identify safety stock, inventory costs, lot size, and reorder point for raw materials to then plan the billet raw material inventory. The data in the company has varying characteristics of the demand level so that the data is processed by the Lot Sizing Silver Meal method, the Economic Order Quantity and the Period Order Quantity. From the results of research and analysis, it is known that the safety stock of billet Q275 / 5SP raw materials is 1,046.68 tons and Re-order Points are 11758.04 tons. And from the three optimal lot sizing methods chosen, the Period Order Quantity method with the total cost of ordering raw materials per year is IDR 340,800.00 as much as four orders. Then inventory planning is carried out which results in a complete inventory cost of Rp 2,815,219,200 or resulting in cost efficiency of 17% compared to company policy which is Rp 3,407,764,327

Abstract

The time needed to set up the production machine is 55 minutes. The high set-up time is caused by the non-differentiation of internal set-up and external set-up so that all set-up activities are carried out when the engine stops (internal set up). When viewed from the effectiveness of the company, the setup activities carried out at the time of the engine stop will significantly harm the company, which in turn will have an impact on the high bottleneck which results in delays in the production process in specific capacities. Research activities are carried out by direct measurement of die casting machines using a stopwatch. In this study, the authors conducted a study to apply the SMED method when setting up die casting machines at PT Mitsuba Indonesia. The SMED (Single Minute of Exchange Die) method as an approach is considered as one of the solutions used to reduce the setup time of the machine. From the results of the study, it was found that the set-up time was 35 minutes, or efficient by 64% on the set-up time before the repair.

Abstract

A company engaged in steel, in its production activities still experienced the highest quality loss with disability in the line of Electrolytic Cleaning Line (ECL) with a percentage of disability of 16%, quality that meets company standards of 80%. The purpose of this study is to determine the baseline performance, identify the causes of disability and propose corrective action plans. This study uses the Six Sigma method that goes through the stages of analysis, namely Define, Measure, Analyze, Improve. The results of data processing, it can be seen that the process DPMO value in the Electrolytic Cleaning Line (ECL) line is 53,827,270 with a sigma level value of 3.11. From the identification of dominant CTQ, it can be seen that the CTQ that often occurs is a type of Soft Eyes. Therefore, for now, Soft Eyes is a priority for improvement. Based on the analysis of the causes of Soft Eyes using Failure Mode And Analysis (FMEA) obtained from the description of the process produces the highest Risk Priority Number (RPN) that is in human factors of 504. Since human factors are the primary cause, the company supervises the operator when doing work, to prevent unwanted defects in the product.

Abstract

This study aims to maximize the decline in the level of product defects to lead to zero defects. Researchers use the six sigma method through 5 stages of completion, namely, define, measure, analyze, improve, and control. Based on the results of the study it can be concluded that the sigma level and the value of DPMO (Defect per Million Opportunities) of the company amounted to 3.47 with possible damage of 24,239 sheets for one million productions. After further analysis using the Pareto diagram, it found that the cutting fault transfer defect was the most common with a percentage of damage of 43%. And based on the results of the analysis of fishbone diagrams, it can be seen that the main factors causing contamination in the production process come from the worker factor (human), followed by machine factors, material, and work methods. The proposed improvements that can be made by the company include updating existing methods and SOPs (standard operating procedures) and monitoring the operator's performance and developing knowledge and planning proper maintenance scheduling.
