<![CDATA[The productivity of filling machines is a critical factor in the skincare industry, but it is often hampered by various losses that have not been comprehensively measured. This research aims to identify the dominant types of losses affecting the efficiency of filling machines at PT XYZ through a qualitative approach. Based on the analysis, it turns out that at PT XYZ, there are 3 products with the highest loss percentages, namely A Body Wash, C Shampoo, and A Hand Wash. Among these products, A Body Wash has the lowest productivity achievement, with 20% of the products reaching a productivity rate of below 1%. The productivity of filling machines for skincare companies needs to show a tendency for low productivity values for Body Wash products.]]>

<![CDATA[Stock investments in the time of the COVID-19 pandemic have a considerable risk. This happens because of the increasingly uncontrolled movement of stock prices. The potential for steep charts can occur at any time. Sentiment analysis of increasing daily cases of COVID-19 was analyzed to see how much effect it has on stock price movements. This research will analyze stock prices from coal commodities in Indonesia. Researchers choose to discuss coal commodities because, in April 2021, there was a significant increase and highest in November 2021. Because of the data, researchers want to see the influence of some coal companies using selling price data with moderating variables for estimating the stock price. There are 26 coal companies that are listed on Indonesia Stock Exchange. The analysis will be a check on five companies that have the largest investors. The analysis is also carried out on coal sales price movements. Furthermore, five different coal mining companies were analyzed based on the rate of price changes to new selling prices with variable moderation in Indonesia. Increasing daily cases of COVID-19 being variable moderation. The method used for finding the relationship is a linear regression with a moderating variable. According to the analysis, the increasing daily case of COVID-19 as a moderating variable is enough to affect the relationship between the selling price of coal and the stock price of HRUM.JK and PTBA.JK. In stock price HRUM.JK, there is an increasing adjusted R square from 0.5254 to 0.5451. The same conditions apply to PTBA.JK has increased by 0.4040 to 0.4444.]]>

<![CDATA[In the manufacturing industry, production line efficiency is an important factor to maximize output and reduce delays. One of the methods used to achieve this goal is line balancing. This research aims to maximize output and reduce balance delay using the Killbridge and Wester line balancing method. The Killbridge and Wester method is used to analyze and balance the production line by combining several operations into one work station, so that the operating time at each station is reduced and more balanced. The results showed a significant increase in production line efficiency. As a result of the author's line balancing, the line efficiency increased from 65.76% to 84.55%, and the smoothest index decreased from 7.33 to 2.77. The author succeeded in combining several operations into one workstation that was more balanced in terms of operating time. The line balancing analysis process that has been analysis process that has been carried out shows an increase in output and a reduction in production time, however still requires further testing to calculate the optimum number of operators at each workstation. in each work station. The line balancing that was carried out proved to be effective in improving production efficiency.]]>

<![CDATA[Non-English major students often face problems in practicing speaking English due to their reluctance. To overcome this, participation scores are used to motivate learners to participate in class discussions. Therefore, this study examines the relationship between learners' participation scores and their English-speaking proficiency. To answer the question, this study implements a quantitative method by collecting learners' participation scores and speaking proficiency. Additionally, data on learners' gender and attendance were included to examine the correlation. The data were collected from 255 students majoring in Information Systems who enrolled in the English for Business Communication class during the academic years 2022–2024. The finding shows that gender has a weak correlation with learners' speaking proficiency. Meanwhile, attendance and participation scores show a positive correlation at the medium level with learners' speaking proficiency.]]>
