Abstract

Procurement of goods and services is a critical step for an organisation to support its operational activities. This activity plays a vital role in the company's operations and is often faced with potential risks that require accurate and optimal risk mitigation. This study was conducted at a unit of PT XXX to analyse and develop risk mitigation strategies in the procurement process, specifically for routine services. The approach used in this study is risk assessment. The research methods include primary data collection through interviews and observations, as well as related references. The results show that out of 16 activities in the procurement process of routine services, 23 risk analyses were identified. These risks were then categorised according to their risk level: 5 high level risks, 17 medium level risks and 1 low level risk. The risk mitigation strategy planning focuses on the high level risks to control and reduce their impact.

Abstract

Quality control is a critical aspect of the textile industry, essential for maintaining product consistency. However, defects in yarn materials continue to persist, particularly during the warping process. This study investigates yarn defects at PT X using the Fault Tree Analysis (FTA) method, identifying 15 root causes and proposing corrective measures based on the 5W1H approach. The research specifically addresses defects in Tetoron Rayon (TR) yarn Ne 30, with a focus on Cross Defects, Defective Rolls, and Nglokor Rolls. The FTA method offers a structured approach to failure analysis, while the 5W1H method is employed to derive strategic corrective actions. The findings demonstrate that the probability of defect occurrence varies between the Direct and Sectional Warping processes. Cross Defects occur with probabilities of 0.1333% and 0.126%, Defective Rolls with probabilities of 0.159% and 0.243%, and Nglokor Rolls with probabilities of 1% and 0.171%, respectively. The analysis identifies 15 primary root causes contributing to these defects, which include machine-related failures, human error, and material inconsistencies. Based on these findings, the study recommends the implementation of preventive maintenance schedules, operator training programs, and a more rigorous adherence to standard operating procedures (SOPs). The proposed improvements are expected to optimize the warping process and enhance the overall quality of the product.
