Abstract

The results obtained from the RCS worksheet show that there is 1 unit of high critical category component, 10 units of medium critical category component and 4 units of low critical category component. Calculation of component requirements for the next 12 months using the Poisson process obtained the total requirement for 4 months of critical component spare parts to be able to meet 95% availability of v-belt mixers is 7 units (12 months = 21 units), hydraulic rubber requires 4 units (12 months=12 units), and vibrating v-belt system requires 2 units (12 months = 6 units). Order size and costs incurred for 4 months for 7 units of v-belt mixer component spare parts of IDR 569,500 (12 months = IDR 1,708,500), 4 units of hydraulic rubber components IDR 653,800 (12 months = IDR 1,961,400) and a v-belt system component of 2 units of IDR 103,300 (12 months = IDR 309,900). The total inventory cost for the 12 months that the company has to pay for the three critical component spare parts is IDR 3,979,800.

Abstract

This research discusses about quality control of book production at CV. Solusi Offset to achieve, maintain, and improve product quality. The purpose of this research is to propose one of the quality control methods in book production at CV Solusi Offset using the seven tools and kaizen methods. The seven tools method is used to identify problems and factors that cause defects in order to find solutions for improving the quality of book products at CV Solusi Offset, while kaizen offers suggestions for improvements to these problems. The results of the check sheet show that in 20 months during the period April 2021-September 2022 that the calculation of the average proportion of defects reached 5.9%, while the company's determination of the proportion of defects is 2-3%. Based on the results of data processing and analysis of the results that have been carried out, it can be concluded that the types of defects occur in cover printing, lamination, imprecise book backs, and inverted book filling. Overall, the causes of defects are caused by irregular maintenance, poor preparation of operation strategies, human error, and environmental factors. To overcome these problems, the author proposes the application of the kaizen method (seiri, seiton, seiketsu, seiso, and shitsuke) which adopts five steps for continuous improvement of processes and products with the responsibility of all workers.

Abstract

Kusuma Mulia Plasindo Infitex is a company engaged in producing cotton fabric as its superior product. With the increasing demand for cotton fabrics, this does not necessarily guarantee in full that the resulting product is free from defects or damage. Based on preliminary observations, especially in the part of the cotton fabric production process, it was found that the product was not feasible or did not meet the standard as much as 9% of the average production a day, namely 10. 000 meters. Meanwhile, the tolerance standard applied by the company is 5%. The purpose of this study is to identify dominant defective products, identify the causes of defective products, know the limits of product quality control in the inspection section and propose improvement plans based on statistical quality control and kaizen methods. Based on the results of statistical quality control on the pareto diagram, it is seen that the most dominant defect is loose feed as 13.178 meters with a defect percentage of 49.24% produced during the 31-day observation. After observing the occurrence of defects in cotton fabrics, there are five factors, namely humans, environment, methods, materials, and machines. On the control map p, there are ten data points that are outside the upper control limit, namely at points 3,4,5,9,17,23,27,29,30, and 31. Then there are eight points that are outside the lower control limit, namely at points 7,12,13,14,18,19,25 , and 26 so it is said that the condition of the cotton fabric production process for 31 days from March 1 to March 1, 2021 has not been controlled so it is necessary to find factors causing defects that are beyond the limits of lower and upper control using fishbone diagrams. Improvements are made to the dominant defects and causes of disability by carrying out countermeasures or follow-up plans using the kaizen five M Checklist, 5W+1H and Five Step Plan methods

Abstract

The production process is said to be good when it produces products that are in accordance with the standards set by the company without any product defects. The company uses the six sigma method as a quality control tool to reduce product defects by implementing the Define, Measure, Analyze, Improve, Control (DMAIC) steps. Six Big Losses and FMEA to analyze the dominant factors that cause defective products and identify defects in concrete buis. This study aims to find out which companies implement quality control using the Six Sigma method. Based on the Six Big Losses analysis, the highest losses were process defect losses of 57.84% and equipment failures of 32.38%. There are 6 critical wastes out of a total of 13 wastes with the highest RPN value, which is caused by a human error of 180. The Sigma value is 3.06 or still within the control limits. Following are some recommendations for improvement that can be given to the company: carry out quality control at each stage of the production process, evaluate the workforce, contract with suppliers of prime quality materials, provide adequate raw material warehouses

UD NOK SUSI is a business unit that produces rope, the purpose of this research is to implement 5S culture and reduce waste. Waste that arises from the remains of raw materials that have accumulated in production narrows the space for the production process and workers who make excessive movements often place tools/items haphazardly. 5S method (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) to reduce waste. Stage Seiri (Brief) is an activity to separate equipment that is not needed. Stage seiton (Neat) is an activity to store goods that are fixed and so that goods are neatly arranged. The seiso (Rehearsal) stage aims to maintain cleanliness in the work environment. The seiketsu (Treat) stage is to continue carrying out activities in the form of sorting, cleaning and arranging the development of positive habits in the workplace. The shitsuke (Diligent) stage aims to get used to the 5S culture. Solutions to reduce waste can also be analyzed using value stream mapping to describe the flow of materials and information in the production process from raw materials to finished products. The VSM mapping results are used to map the PAM. Process activity mapping to map all activities in detail in order to reduce waste. Reduced wastage. sorting process, namely: untying, separating. Small spinning namely: preparing the small mill, moving the pellets. Big spinning, namely: pulling the rope, preparing the reel tool, taking the big spinning rope. Finishing namely: attaching labels. The cycle time obtained was 398.80 minutes which was previously 419.44 minutes
