Abstract

This study aims to analyze the root causes of these problems and take corrective actions to improve product quality. Improvements are made using the SixSigma approach using the DMAIC cycle. Brainstorming and Fishbone diagrams analyze causal factors. The priority of the problem that needs to be fixed based on the highest RPN value is that the Backwash filter is too short and the filter regeneration duration is not optimum. Improvement plans from the 5W + 1H analysis were applied by increasing the period of the backwash filter and changing the regeneration schedule. After that, cooling water loss data is collected in May-September 2017. Comparison of the production process conditions between before and after repairs is seen by calculating the process capability — the results obtained where Sigma values rose from 3.5 to 4.5 which is a reasonably good increase because the increase in the value of 1 sigma is substantial value in the framework of the existing loss emphasis on a system.

Abstract

The method used to solve this problem is the overall equipment effectiveness (oee) and failure mode effect analysis (FMEA) methods on the roughing stand machine. The results of the research on the Roughing Stand 3 machine produced OEE values in July - December 2016 was July 87%, August 59%, September 78%, October 40%, November 74% and December 7%. The potential failure priority is based on the order of Risk Priority Number (RPN), the screw-up item does not work has the most considerable RPN value, so the focus of repairs or component changes can be specified on the subject. If the thing is running regularly, it can switch to the second highest RPN value; the rolling gap is unstable. The root of the problem of potential failure according to the RPN screw up ranking does not have the highest value, so it needs to be made fishbone to find out the components of the cause. The causes in terms of the environment are Dust, cooling process water, too hot temperatures, and less clean areas, for the method category do not do according to SOP so that maintenance actions are not routine, for machine tolerance engine suitability/engine accuracy decreases because the engine is old, gear coupling falls worn gear, in terms of material  specifications do not meet the standards, and from the human being there is no particular task to oversee the unit.

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 doesnt 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

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 at PT Adhi Karya, 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.
