Abstract

This study examined the effect of job training on employee performance in the Incoming Quality Control (IQC) department of PT XYZ, where inspection accuracy is essential for maintaining product quality and operational efficiency. A quantitative approach was used, with data collected from 50 IQC employees through a structured questionnaire. The data were analyzed using validity and reliability tests, as well as simple linear regression in SPSS version 25. The findings indicated that job training had a positive and statistically significant effect on employee performance. Improvements were observed in productivity, work quality, timeliness, and cycle time efficiency. These results emphasize the important role of training in improving employee competencies and supporting effective quality control. This study is limited to a single department with a relatively small sample size, which may affect the generalizability of the findings. This study provides empirical evidence that job training is a strategic investment in human resource development in manufacturing organizations.

Abstract

The competition in the Bottled Drinking Water (AMDK) industry in Indonesia, particularly in the Jabodetabek region, has shifted from price wars to a focus on reputation and product value. This phenomenon is highlighted by the significant rise in Le Minerale’s market share, which challenges the dominance of established market leaders. This study aims to analyze the influence of Brand Image and Brand Trust on consumer Purchase Decisions for Le Minerale products. This research employed a quantitative approach, collecting data from 120 respondents in the Jabodetabek region selected through purposive sampling. The data were analyzed using Multiple Linear Regression with SPSS version 26 software. The results indicate that both Brand Image and Brand Trust, whether tested partially or simultaneously, have a positive and significant influence on consumer purchase decisions. The coefficient of determination reveals that these two variables contribute 58.2% to the purchase decision, while the remaining percentage is influenced by other factors outside this study. These findings suggest that building a modern product image and maintaining strong consumer trust are key strategies for winning competition in the bottled water market.
