Abstract

PT Topjaya Antariksa Electronics is a manufacturing company that produces various refrigerators, home freezers, and showcase refrigerators. Refrigerators are produced in the form of single doors and twin doors. This company was founded in 1988 and distributed by Toshiba Sarana Utama throughout Indonesia. This research is intended to reduce the process failure rate so that the potential for defects produced in the polyurethane shop is reduced by finding repair solutions. This study aims to plan improvement efforts to reduce process failures in the polyurethane shop and then evaluate the results of implementing the proposal. The FMEA (Failure Mode and Effect Analysis) method is used. This method performs several stages, such as determining the potential failure mode in each process, identifying the cause of failure, and then making a priority order. Process failure in this polyurethane shop is the most significant process failure compared to other shops. This failure causes the defects in the process at the polyurethane shop to be higher than in other shops. In 2019, 2020, and 2021, the number of refrigerator cabinets in the flawed polyurethane injection process amounted to 7,666 units, 8,256 units, and 8,014 units. The percentage of defects compared to the amount of production found in the polyurethane injection process each year was 18.46%, 17.82%, and 18.11%.

Abstract

technology, namely the use of e-Library as an online catalog facility to directly access collections of books, theses or other collections contained in the library. This research is based on the fact that users feel dissatisfied with the services provided by the e-Library, such as collections and collection information that do not meet user needs. The purpose of this study was to measure the level of satisfaction of e-Library users using the End User Computing Satisfaction method with five perspectives namely Content, Accuracy, Format, Ease of Use, and Timeliness. The Impotance Performance Analysis (IPA) method is used to determine which attributes are important to be improved and which need to be reduced to be interpreted in the form of a matrix. This study also calculates the value of Customer Satisfaction Index (CSI) to determine the overall level of user satisfaction. The results of this study show that all attributes in terms of Importance are in a very important category, while the Performance attributes are in the satisfied category, namely the Content and Format variables. Variables with quite satisfied categories on Accuracy, Ease of Use and Timeliness variables. The results of the IPA matrix obtained 6 attributes with the most improvement in the Accuracy variable, the attribute with the most good performance in the Content variable. Overall, the CSI value is 60.34%, which means that users are quite satisfied with the performance provided by the e-Library
