Abstract

Effective spare parts management at PT XYZ requires accurate classification based on their turnover rate. This research aims to categorize spare parts into fast-moving, slow-moving, and non-moving categories to improve inventory management efficiency and support the company's operational sustainability. From the analysis of 130 types of spare parts, it was found that 69 (53%) fell into the fast-moving category, 50 (38.5%) were slow-moving, and 11 (8.5%) were non-moving. This classification is critical because it allows the company to determine the optimal order quantity and storage location for each category of spare parts. Thus, the company can prevent stock shortages on frequently used parts, which can disrupt smooth operations. In addition, activities with the grouping of goods can increase the accuracy of the stock-taking process, making it easier to make decisions related to inventory management. The data in this study were collected through various methods, including direct observation, literature study, and analysis of company historical data. The results show that classifying spare parts based on turnover ratios can be a solid basis for more effective inventory management policies. The application of this classification, PT XYZ is expected to improve operational efficiency and optimize the use of existing resources, to contribute to the growth and desire of the company in the future.

Abstract

Product quality plays an important role in the cable industry to meet standards and improve customer satisfaction, but product nonconformity is still an obstacle that affects production efficiency and costs. This study applies the Six sigma method with the DMAIC approach to the Improve stage to identify the causes of nonconformity and provide recommendations for improvement. The results of the study show four categories of Critical to Quality (CTQ) in cable products, with visual nonconformity as the most dominant at 423.167 km. The U control chart analysis shows that the variation of nonconformity per unit is still outside the statistical control limits, indicating that the production process is not yet stable, with a sigma level of 3.982, indicating significant opportunities for improvement. Based on the Pareto analysis, visual nonconformity is the main priority with the main causes coming from man, machine, method, material, and environmental factors. Recommendations for improvement include increased supervision, periodic machine maintenance, and operator training. Implementation of continuous improvement is expected to reduce nonconformity and improve the quality and efficiency of cable production.

Abstract

The competition among private universities (PTS) in Bandung is intensifying as Generation Z, which dominates the student population, becomes increasingly reliant on social media. This study aims to identify and analyze the key factors influencing PTS selection to provide insights for improving marketing strategies. A quantitative approach was used with purposive sampling, involving 136 respondents, and data was analyzed using the PLS-SEM method. The results indicate that among the four tested variables, career opportunities and word of mouth significantly influence student’s decisions in choosing a PTS, whereas influencers and brand image do not have a significant impact. To enhance career appeal, PTS should maintain a strong balance between theory and practice in study programs. Additionally, improving student satisfaction and involving parents can strengthen the effectiveness of word-of-mouth promotion. These findings offer valuable input for PTS in refining their marketing approaches to attract more students in an increasingly competitive education sector.
