Abstract

A yarn company strives to produce good and quality products, but the production process that is carried out by each person will produce products targeted at a target that has been set at 5%. This study uses the Six Sigma method but only until the improvement stage. The research is to determine the DPMO value and sigma level in the spinning production process, to know what factors cause defects and new parameters to reduce the defect. Based on the results of the study that the DPMO on the type of CD thread in the spinning section is 17,130 and the sigma level is 3,6. The level of sigma that has dominated the Indonesian industry average, but has a defect of 8.7%, the target set at 5%. Damaged and dirty apron, clogged trumpet, and leaky hose are factors that plan defects. Furthermore, with Failure Mode Effect Analysis (FMEA), the highest value of Risk Priority Number (RPN) in tangled defects is that the apron is damaged (140) and clogged trumpet (120), while the highest RPN value is gross dirty, i.e., dirty apron (150) and hose leaking lubricant (120).

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.

Abstract

The problem that occurs in the production of sintered ore is the number of defective products. In this study it was conducted with the aim of knowing the factors that cause the product to become broken, understanding the processes that most often appear following the elements and providing proposed improvements to improve product quality and reduce them using the method of failure mode and effect analysis and seven tools. Based on the results of the highest Risk Priority Number (RPN) is the proportioning process with a score (252), Sintering with a score (168), Drum Mixing 2 with a score of 126, drum mixing 1 with a dozen (90), sintered cooling with a rating (45), and a sinter crusher with a score (18). The priority for repairs is the proportioning process.

Abstract

The production process of API 5L PSL2 pipes in Pipe Companies in 2017 happened to defect products at 7%. This defect is still above the standards set by the Company at 4%. The study aims to determine the value of sigma and provide recommendations for improvement with the six sigma method. Based on the results of the DMAI analysis, the amount of the pipe sigma level was 3.65 with the value of DPMO 14448. Types of defects identified in the process such as open welding defects, high lows, contact marking, scarring, and under dimension Proposed improvements were made by designing recommendations for improvements using 5W + 1H by checking the condition of the forming machine and changing bearing components before the bearing lifetime, performing preventive maintenance every week and adding coolant bursts to the cutting tool.

Abstract

Hanifah Collection is a company engaged in the convection of school uniforms. The fluctuating number of requests each month creates its problems in determining the amount of production. This study aims to find a method that matches the data pattern as the basis for determining the amount of output in the next period. The technique used in this study is the forecasting method of Moving Average, Exponential Smoothing and Triple Exponential Smoothing with parameter level errors of each way using MAD, MSE, and MAPE. From the results of this study, there is a moving average method with the most appropriate method in determining demand forecasting in the next period with a value of MAD of 172.22, MSE of 46624.34 and MAPE 46624.34.

Abstract

CV. ABP a construction company worked in infrastructure building development for private and goverment. Now CV. ABP is handling infrastructure development project of the acropolitan area (Right Payment) Sukaci - Baros Village. This project has been late for 19 days from the dead line 126 days. Therefore the cost is getting higher. It happened because bad management is the problem source. Restoring the project time need to be focused on the cost and the due date based on the schedule. Scheduling evaluation using Critical Path Method (CPM) and Crashing to find optimal results using Critical Path Method (CPM) can be found the critical paths activity, there are ground digging , bopflang installation, stone installation, agregrate B agrgregation , aggregate A flatting, rigit bavement work, and refining, when the time suppression obtained optimal time results from 126 days to 92 days. It taken an alternative to the addition of working hours with duration 92 day after the crashing. Using two alternatives, additional working hours and the addition of workforce, obtaining the difference of extra hours of work cost Rp 80.128.125 and labourcost increase Rp 55.260 from the regular cost.
