Abstract

In the manufacturing industry, industrial competition is increasingly competitive, to produce a product that has high quality to be an added value in XYZ company's competitive advantage, so that companies produce good quality products by meeting consumer standards and tastes for the products they produce and reduce the level of product defects by the company. This study aims to analyze defective products on Part lockwasher at PT XYZ. The research used the Six Sigma method to control product quality through 5 stages, namely define, measure, analyze, improve and control. From the results of this analysis, it was found that there were 3 types of product defects that caused the resulting defects, namely high torque values, rotating bolts, and easily detached stoppers caused by machine, human, and method factors. the results of the six sigma calculation of defective products Part lockwasher during April-December there is a six sigma level of 3.463 with an average DPMO of 24803.43, and knowing the highest level of defects is caused by high torque values. These results indicate that product defects in Part lockwasher are on average for the Indonesian industry. The proposal given in this study uses 5W + 1H as an improvement to improve product quality.

Abstract

In determining alternative decisions for improving its employee performance, PT. Cipta Karya Abadi appraises its employee performance with the help of predetermined criteria limits. To find out the level of quality of employees, work facilities, employee welfare which is a priority in performance improvement strategies so that employees get comfortable and motivated and can reduce feelings of boredom when carrying out work, can be conducted by looking at some of the problems that occur in the company. This research was conducted to find out strategies that can be used to increase employee performance in making a company organization more efficient. Based on the results described in the results and discussion, it can be concluded that the criteria used as a reference in employee performance improvement strategies are additional tasks, management skills, work skills, and communication skills. From the above criteria, several alternatives proposed by the company to improve employee performance. They are HR Quality Improvement, Work Facilities Improvement and Welfare Improvement. The three calculations that have been carried out using the Analytical Hierarchy Process (AHP) method to determine employee performance improvement strategies show that the first alternative priority is to increase work facilities with a priority value of 0.3448, then the second and third alternatives are to improve the quality of human resources and increase welfare by the same priority value of 0.3276.

Abstract

Product quality control is very important to pay attention to so that a company can continuously compete with other companies, increase its sales value, and get the trust of customers as its most important target. PT JP is an industrial company engaged in manufacturing with packaging products made from polypropylene/Impraboard, Cardboard Box, Polyethylene Foam, Spon Eva, and other packaging need materials. One of the products with a high sales rate is imprabox products. But, during the inspection process, there is a fairly high and diverse defect rate. Therefore, efforts are needed to minimize product defects using the basic seven tool method. This research begins with product inspection using a cheksheet in the QC (Quality Control) department. The inspection is carried out 23 times with a total of 3,256 items and 941 NG products. Furthermore, a flowchart is made to display the manufacturing process starting from marking, cutting, bending or fit up, welding, to finishing. Histogram is used to determine the variation of defects, in this case there are 12 types of defects including printing, EVA coating and NG cover. Pareto diagram is used to determine the dominant defects including in printing at 41.34%, Eva coating at 22.85% and NG cover at 11.265. Ishikawa/fishbone diagram is used to determine the causes of defects including human factors, machine factors, method factors and environmental factors. Scatter diagram is used to express the 77% relationship (correlation) between the variation in the number of defective products and the amount of production. The control diagram is used to analyze the control limits with UCL 40.9 and LCL 0.403.

Abstract

Most people have switched to using bottled drinking water that is consumed compared to PDAM water that is cooked by themselves. Therefore, the determination of the shortest route for the distribution of bottled drinking water delivery (AMDK) to the last distribution route is carried out. Determination of the shortest route taken in carrying out distribution is carried out because there are often vacancies at agents caused by delays in delivery by the depot so that in this case the distribution of bottled drinking water becomes very crucial in fulfilling public demand for bottled drinking water needs. Delays in distribution from the depot can be caused by a lack of efficiency in the delivery path so that several obstacles are encountered during the process. Therefore, the shortest route optimisation will be carried out for the efficiency of distribution time which aims to increase customer satisfaction related to product availability in accordance with the demand submitted by the community which is expected to have a smooth distribution path that will impact on the timeliness of product arrival using the Vehicle Routing Problem (VRP) method. Where this method is used in a distribution system to create an optimal route. Based on the results of determining three preferred routes, for determining the distribution route from Kasomalang to the final destination, Garut, the second route was selected as the shortest route determined by
