Abstract

This study analyzes the effect of price, riding safety, and service quality on GoRide customer satisfaction in Tegal Regency using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. Data were collected from 100 GoRide users through a 5-point Likert-scale questionnaire. SmartPLS 4.1.0.9 was used to assess the validity and reliability of the research instrument, and to evaluate both the measurement (outer) and structural (inner) models. The results show that all outer loading values exceed 0.7 and Average Variance Extracted (AVE) values are above 0.5, indicating good validity and reliability. The inner model analysis confirms that price, riding safety, and service quality significantly affect customer satisfaction, with riding safety having the strongest impact. These findings suggest that service providers should focus on improving safety standards, enhancing service quality, and ensuring price transparency to boost customer satisfaction.

Abstract

PT. XYZ is engaged in the manufacturing industry. In the work process, especially in the warehouse section with a fairly fast intensity in supplying production, a proper and safe work process is required. In the work process in the warehouse, there are problems conveyed by the operator regarding the pain felt in the arms and waist during the work process. The pain experienced includes Musculoskeletal Disorders (MSDs), which is pain felt by the muscles, this study aims to determine the level of risk of body posture during work using the Rapid Upper Lamb Assessment method, what factors cause this to happen. The results of the analysis using RULA and improvements, obtained unsafe work postures due to inappropriate tools and causing pain to the operator, with improvements to the work tools used, the pain experienced by workers subsided and disappeared during the work process

Abstract

This study aims to analyze ergonomic risk in manual lifting activities at the food storage warehouse of PT XYZ, located in Cikarang Barat, using the NIOSH Lifting Equation method. A total of 20 workers were observed, with ergonomic variables measured such as load weight, lifting frequency, lifting distance, and body posture. The results showed that the average initial Lifting Index (LI) was 2.328, significantly exceeding the safe threshold (LI ≤ 1), indicating a high risk of musculoskeletal disorders. After an intervention using a team lifting system, the average LI decreased to 1.207. Although not yet fully within the safe zone, this method effectively reduced ergonomic risk. Recommendations include ergonomic training, use of lifting aids, and broader implementation of team lifting. This study employs a descriptive quantitative approach.

Abstract

PT. X is a manufacturing company that produces fire extinguishers (APAR), where cylindrical plate welding is a critical process. However, the process is often inefficient due to several non-value-added steps. This study aims to improve welding productivity using Lean Six Sigma through the DMAIC (Define, Measure, Analyze, Improve, Control) approach and by measuring Overall Equipment Effectiveness (OEE). The initial OEE value was 67.49%, far below the world-class standard of 85%. Pareto analysis showed the highest downtime was due to cycle time issues, especially during setup and cutting of additional plates. Improvements were made by eliminating the cutting process and adding a stopper to ensure accurate welding positions. These changes reduced the cycle time from 180 seconds to 120 seconds and increased the OEE to 76.12%.
