Abstract

The salt boiling process in small-scale industries is still largely performed manually, requiring repetitive physical activities that can potentially lead to musculoskeletal disorders among workers. This study aims to evaluate ergonomic risks in the salt boiling process and formulate improvement interventions to reduce these risks. A quantitative approach was applied through work posture observation, the Nordic Body Map (NBM) questionnaire, and posture assessment using the Rapid Entire Body Assessment (REBA) method on three operators in a salt industry laboratory. NBM results indicated that the highest complaints occurred in the back, waist, shoulders, and lower limbs. REBA analysis identified the drying stage as the most high-risk activity (score 10, very high), followed by salt cooking (score 8, high), and fire stove preparation (score 6, medium). Based on these findings, interventions such as adjusting worktable height, using lifting aids, and implementing job rotation are recommended to reduce injury risk while improving operator productivity.

Abstract

This study aims to analyze the effect of product quality and service quality on sales performance at PT XYZ in Surabaya. A quantitative approach with a survey method was employed, involving 100 respondents who were active consumers. The research instrument was a structured questionnaire that had been tested for validity and reliability. Data were analyzed using multiple linear regression with SPSS. The results indicate that both product quality and service quality have a positive and significant effect on sales performance, either partially or simultaneously. Product quality shows a stronger influence compared to service quality, with a regression coefficient of 0.412. The adjusted R² value of 0.327 reveals that 32.7 percent of sales performance variation can be explained by the two variables, while the remaining 67.3 percent is influenced by other factors. These findings highlight the importance of integrating product quality and service quality to strengthen competitiveness in the beverage industry.

Abstract

This study aims to analyze the effect of organizational culture and work motivation on employee performance at a traditional medicinal powder company in Surabaya. A quantitative approach was employed using a survey method with a Likert-scale questionnaire. The sample was determined using Slovin’s formula, involving 71 randomly selected respondents. Data were analyzed through validity and reliability tests, classical assumption tests, and multiple linear regression using SPSS version 25. The results indicate that organizational culture has a positive and significant effect on employee performance. Work motivation also shows a positive and significant effect, and it is identified as the most dominant factor in improving performance. Simultaneously, organizational culture and work motivation contribute 75.9% to variations in employee performance, while the remaining 24.1% is influenced by other factors outside the research model. This study emphasizes the importance of strengthening organizational culture and enhancing work motivation to sustain employee performance in the traditional cosmetics industry.
