Abstract

In the modern era, consumers prioritize convenience and speed in shopping, making drive-thru services an innovative solution to meet this demand. To retain customers, Customer Satisfaction is the key to winning the competition. This study aims to examine the relationships between variables influencing Customer Satisfaction and their impact on Repurchase Intention. The research variables include Perceived Value (X1) and Service Quality (X2) as independent variables, Repurchase Intention (Y) as the dependent variable, and Customer Satisfaction (Z) as the mediating variable. Each variable will be measured by its respective indicators. This research employs a causal research design with a quantitative approach, utilizing primary data collected from 160 respondents via accidental sampling. Data analysis was performed using the SEM-PLS method. The results show that Perceived Value and Service Quality have a significant positive effect on Repurchase Intention. Perceived Value has a positive but not significant effect on Customer Satisfaction, while Service Quality has a positive effect on Customer Satisfaction. Customer Satisfaction mediates the indirect effect of Service Quality on Repurchase Intention but does not mediate the effect of Perceived Value on Repurchase Intention.

Abstract

This study analyzes the efficiency of diesel fuel inventory management at PT. XYZ, located in Desa Peunaga Cut Ujong, Kecamatan Meureubo, Kabupaten Aceh Barat, Aceh. The main problem faced by the company is inefficient fuel inventory management, leading to a mismatch between stock and usage, potential equipment downtime, and high inventory costs. The research objective is to evaluate PT. XYZ's current fuel inventory policy and compare it with the application of the Economic Order Quantity (EOQ) method to identify potential improvements in efficiency and cost savings. The research method used is a quantitative approach with a comparative descriptive design. Secondary data, including records of fuel purchases, usage, and ordering and holding costs for 2024, were collected from PT. XYZ's Supply Chain Management (SCM) division, supplemented by primary data from interviews. Data analysis involved calculating EOQ, determining optimal ordering frequency, safety stock, reorder point, and comparing the Total Inventory Cost (TIC) between the company's existing policy and the EOQ method. The results indicate that PT. XYZ's current fuel inventory management policy incurs significantly higher Total Inventory Costs (TIC) compared to those achievable using the EOQ method. Implementing EOQ substantially optimizes order quantity, frequency, safety stock, and reorder point, which in turn can lead to considerable cost reductions. This suggests that adopting the EOQ recommendations can improve operational efficiency and provide financial benefits for PT. XYZ.

Abstract

This study aims to evaluate the work system in the PT. Mulia Multi Medika warehouse using an integrative approach of Macroergonomic Analysis and Design (MEAD) and Macroergonomic Analysis of Structure (MAS). The method stages include: (1) identification of the environment and organizational structure; (2) definition of the work system through SWOT analysis; (3) setting performance expectations and mapping subsystems; (4) ergonomic risk assessment using the Workplace Ergonomic Risk Assessment (WERA) and Job Strain Index (JSI); and (5) analysis of the work environment in the form of temperature and noise. In addition, interviews with managers and workers were conducted to capture subjective perceptions of workload and system effectiveness. The results show that worker 1 has a WERA score of 41 (moderate risk) and a JSI of 18 (high), while worker 2 has a WERA score of 35 (moderate) and a JSI of 6.75 (low). The temperature of 18–22°C and noise of 68–72 dB are still within safe limits. The MEAD–MAS analysis revealed role imbalances and technological limitations. Recommendations for improvement include the use of material handling aids, role redistribution, and continuous evaluation to reduce ergonomic risks while increasing productivity.

Abstract

The flow of process is a sequence of jobs or activities performed in producing goods and services. UD. Usaha Rezeki Prabot, a small-to-medium enterprise (SME) in furniture manufacturing, consistently faces a critical operational challenge: despite stable customer demand (853 units/year of panel door type 7), only 750 units (88%) are delivered on time, resulting in a 12% delay rate. This gap is not caused by insufficient labor or machinery, but by a fragmented production system riddled with non-value-added (NVA) activities particularly repetitive machine setup, excessive material handling, redundant measurements, and long waiting times that inflate lead time to 176.91 minutes per unit. Value Stream Mapping (VSM) is applied as a lean tool to visualize the entire material and information flow, identify dominant wastes (waiting, over-processing, and unnecessary motion), and redesign the workflow. Through the implementation of future-state mapping by grouping components with identical profiles into batch processing and eliminating redundant inspections the NVA time was reduced from 79.95 minutes (45.19%) to 16.07 minutes (15.93%), cutting total lead time by 43%. This study demonstrates that for SMEs like UD. Usaha Rezeki Prabot, sustainable productivity gains come not from capital investment, but from restructuring workflow based on frontline insights to eliminate systemic waste embedded in daily routines. The purpose of this mapping is to identify all types of waste along the Value Stream and to take a move in an attempt to eliminate the waste. The flow of process design with Value Stream Mapping approach enables the company to be able to minimize the non value added activities and to shorten the time taken in the process of making doors and to increase the productivity. The purpose of this Motion and Time study was to do a direct observation about time and movement of someone who is working. UD Rezki Prabot uses the VSM (Value Stream Mapping) to minimize the non value added process and to propose a design to improve the flow of process. The result of this study showed that the time of non value added activities decreased from 176.91 minutes to 100.9 minutes. The non value added activities decreased from 45.19% to 15.93% due to the decrease of non value added activities by sequencing the work activities that the machine does not need to be set up repeatedly.

Abstract

One of the most prominent types of home industries operated by local entrepreneurs is the food processing sector, particularly the production of skin crackers.  However, the production process remains predominantly manual, with workers performing each stage such as cutting, drying, frying, and packaging either individually or in groups. Such manual operations inherently expose workers, especially older individuals, to ergonomic risks. Many workers have reported experiencing musculoskeletal discomfort, including rheumatic pain and muscle stiffness, due to prolonged and repetitive tasks. This study aims to analyze workers’ upper body postures to identify potential musculoskeletal disorders (MSDs) using the Nordic Body Map (NBM) Questionnaire and to evaluate work postures using the Rapid Upper Limb Assessment (RULA) method. Data were collected through structured interviews and direct field observations in the skin cracker home industry. The results indicate a RULA score of 7 for all key production processes cutting, drying, frying, and packaging, corresponding to Action Level 4, which signifies that immediate investigation and corrective action are required. The recommended measures include implementing regular stretching or exercise between work activities, redesigning workstations and tools based on workers’ anthropometric data and task requirements, regulating working hours to not exceed eight hours per day, and conducting periodic layout reorganization and workplace maintenance to enhance safety and productivity.
