Abstract

Effective material procurement is an important factor for the success of a company's operations, especially in a manufacturing industry with a high level of complexity such as that operated by PT XYZ. In this case, effective material management not only affects the smoothness of the production process, but also contributes to the company's overall competitiveness and performance. A study on the influence of material variations listed in the request letter and the time required for material procurement at PT XYZ was conducted to reduce risks that could potentially disrupt material management performance. This study is based on statistical analysis. The results of the hypothesis test show that the relationship between VJ (Type Variation) and WP (Procurement Time) is significant, with a t-statistic of 2.318 and a p-value of 0.020 <0.05. The relationship between VS (Specification Variation) and WP also shows significant results with a t-statistic of 2.411 and a p-value of 0.016. Thus, VJ and VS have a significant effect on WP. By understanding this correlation, companies are expected to be able to identify areas that need improvement in the procurement process, as well as reduce the risk of delays that can affect overall performance.

Abstract

PT XYZ is one of the largest food and beverage companies in Indonesia. In carrying out the production process, the company always strives to produce good products with minimal defects. Defects in the production process are unavoidable. Therefore, a study needs to be conducted to determine the factors that cause packaging defects. The methods used in this study are Six sigma and failure mode effect analysis (FMEA). Based on the results of the study, the three highest types of defects for biscuits were obtained, namely cutter seal cookies, folded packaging, and scratched packaging. The average sigma value was 3.59 with a possible defect of 18329.7 for one million processes. Furthermore, based on the analysis using the FMEA method, the main priority of improvement based on the highest Risk Priority Number (RPN) value that must be carried out by PT XYZ is directed at the cause of the cutter seal (KKC) clamp cake defect with a non-standard dimension with an RPN value of 240, the cause of the packaging defect folding the slide rail plate with an RPN value of 180, and the cause of the KKC cake defect setting the non-standard disc feeding with an RPN value of 144. It is hoped that this study will be able to reduce product packaging defects so as to generate maximum profits.
