Abstract

This study aims to analyze ergonomic risk levels among sewing workers at Murya 2 Collection using the Nordic Body Map (NBM), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). This study used a descriptive design with an observational ergonomics approach. The subjects were six active sewing workers, and data were collected through NBM questionnaires, direct observation, photographic documentation, and interviews. NBM was used to identify subjective musculoskeletal complaints, while RULA and REBA were applied to assess objective postural risks during sewing activities. The results showed that the highest complaints occurred in the upper back, neck, lower neck, right shoulder, middle back, lower back, right wrist, right hand, and right foot sole. Based on total NBM scores, two workers were categorized as high risk, while four workers were categorized as moderate risk. RULA results showed that most workers were in the medium-high risk category, whereas REBA results indicated that all workers were in the medium risk category. The use of the three methods showed that dominant complaints were generally consistent with postural risk findings. Recommended improvements include scheduled microbreaks, targeted stretching, posture awareness, foot relaxation, and simple workstation adjustments suitable for SME conditions.

Abstract

Intuition-based inventory planning at PT XYZ, a brand-owning bottled water company, has led to inventory imbalances resulting in overstocking and stockouts that trigger cost inefficiencies. This study aims to perform a comparative analysis between the company's actual policy, the Continuous Review System (Q-System), and the Periodic Review System (P-System) methods to optimize inventory costs. The research utilizes a quantitative comparative approach on 330 mL and 600 mL variants using 2025 operational data. The results indicate that the Q-System can reduce operational costs by up to 33,62%, while the P-System only yields marginal cost savings of 4,04% compared to the actual method. For both the 330 mL and 600 mL variants, the Q-System proved to be the definitively superior model by maintaining a much smaller, yet highly secure safety stock. In conclusion, the company is advised to fully transition its inventory policy to the Q-System to minimize physical holding costs while effectively eliminating the expensive risk of stockouts in a volatile market.

Abstract

This study aims to analyze customer satisfaction toward service quality at PH Clothing in Malang City using SERVQUAL, Customer Satisfaction Index (CSI), and Importance Performance Analysis (IPA) approach. A quantitative descriptive method is employed by involving 75 respondents. Data are collected from a structured questionnaire based on five SERVQUAL dimensions and analyzed through gap analysis, CSI computation, and IPA mapping. The results indicate that all SERVQUAL dimensions exhibit negative gap values, with the largest gap found in the reliability dimension (−1.45), highlighting issues in product consistency and delivery punctuality. The overall service quality ratio (Q = 0.958) confirms that service performance has not yet met customer expectations. The CSI value of 72.62% places customer satisfaction in the “satisfied” category. IPA results identify four critical attributes requiring immediate improvement, i.e. clarity of production and delivery information, complaint handling, product quality, and service speed. These findings provide actionable insights into strategic service improvement to enhance customer satisfaction and competitiveness.
