Abstract

CV XYZ is a retail store located on Jl. Tidar, Surabaya, East Java, specializing in the trade of industrial and household chemical products. To remain competitive amid rapid technological advancements and increasing competition in the area, CV XYZ has adopted online sales through the Shopee platform. This study aims to analyze consumer purchase patterns using the Apriori algorithm based on sales transaction data to support effective and efficient marketing strategies. Based on the analysis, five purchasing patterns were identified: (1) if Silicon Oil is purchased, Counterdust will also be purchased with a support value of 0.391 and a confidence value of 0.818; (2) if Cocamidopropyl Betain is purchased, Counterdust will also be purchased with a support value of 0.391 and a confidence value of 0.857; (3) if Car Shampoo is purchased, Counterdust will also be purchased with a support value of 0.359 and a confidence value of 0.868; (4) if Talc is purchased, Counterdust will also be purchased with a support value of 0.348 and a confidence value of 0.842; and (5) if Linear Alkylbenzene Sulfonate is purchased, Counterdust will also be purchased with a support value of 0.359 and a confidence value of 0.892. These findings indicate that data mining techniques using the Apriori algorithm provide an effective approach for identifying consumer purchasing patterns of chemical products sold online through the Shopee platform. This insight can help businesses optimize their marketing strategies and decision-making processes.

Abstract

Companies in the industrial world, both manufacturing and service industries, are required to face market competition in order to compete and survive. One thing that companies need to pay attention to is the quality of the products produced. Good product quality will make consumers like the product. Therefore, improving product quality must be considered by the company. One of the companies that produces fabric, namely PT. XYZ, has a problem of not knowing the level of quality of the fabric produced, so this study aims to determine the quality of the product and provide suggestions for improvement to the company. There are defects in fabric production, namely double weft with a percentage of 27.7%, loose weft 26.7%, broken warp 24.5% and thick weft 21.2%. Improvement proposals are given to the highest percentage of defects, namely double weft with the following proposals: Carrying out machine maintenance and replacing the new gun eye so that the gun eye is not blunt, replacing the roller on the worn warping machine with a new roller, providing comprehensive and intensive training to workers on how to use the machine effectively and correctly. It is hoped that this research can help the company improve the quality of the fabric products produced.

Abstract

PT Wonojati Wijoyo is a company that produces furniture for export. In carrying out the production process, work accidents often occur. One of the causes is the factor of human negligence. Work accidents that have occurred include torn wounds due to being hit by a machine, legs hit by wood to make them swollen, fingers hit by machines to open wounds, fingers caught in blocks to open wounds. This study aims to determine the value of Human Error Probability (HEP) and recommend improvement strategies for activities that have the potential to cause human errors to minimize work accidents. The method used in the analysis of human error is the HEART method and the SHERPA method. The results showed that there are critical activities that have the potential for human error to occur, namely in 14 subtasks of 9 processes. The highest probability of human error is in the subtask of cutting wood plates using a circle machine with a HEP value of 0.88827 including the high category. While the lowest probability of human error is in the subtask of setting a copy machine with reference wood with a HEP value of 0.00372 including the medium category. One of the recommendations for improvement strategies to minimize work accidents is that the company needs to conduct training on K3 on a scheduled basis with an explanation of the risks that occur if you do not use Personal Protective Equipment (PPE).
