Optimasi Persiapan dan Pengujian Durabilitas Catridge Kran Air Dengan Seven Tools Untuk Meningkatkan Efisiensi Produksi Di PT. STI

Abstract

Acceleration of the process in product design is very important today. Thus, the time the product reaches the consumer is faster. The process of preparing and testing cartridges often takes time and resources, resulting in production delays and potentially affecting customer satisfaction and also wasting water resources used for testing. Product testing serves to validate product quality whether it is in accordance with specifications. This study was conducted to determine the causes and corrective actions for the length of the testing process carried out by the R&D team. The method used in this research process is Seven Tools. With additional calculations of NGT and 5W1H. From the analysis of the results obtained, the most dominant problem is the length of the test preparation process for the cartridge mechanism with a time value of 1980 minutes with a percentage of 70.7%. The most dominant problems include the fixed jig design so that it cannot be adjusted (NGT value 30) and the long dandori time (NGT value 25). The corrective actions that need to be taken for the 2 dominant causes of the problem are to repair the jig that originally could not be adjusted or set to make or repair a jig that can be set or adjusted. The results of this study are expected to be a future reference in the design process of jigs or testing process aids so that they are easy to use.
