Abstract

Intense competition within the low-cost carrier (LCC) industry has shifted the strategic focus from price superiority towards enhancing service quality and passenger satisfaction. This study aims to analyze the strategic role of the operational process of baggage handling in shaping passenger satisfaction by examining the mediating role of Service Quality. Employing a quantitative approach with the Partial Least Squares Structural Equation Modeling (PLS-SEM) method, data were collected via a questionnaire from 100 respondents, who were predominantly young passengers (under 25 years old) and university students. The findings indicate that Baggage Handling has a direct, positive, and significant influence on both Service Quality and Customer Satisfaction. Furthermore, Service Quality is also proven to have a positive and significant effect on Customer Satisfaction. The most critical finding is the confirmation of the partial mediating role of Service Quality in the relationship between Baggage Handling and Customer Satisfaction. This result implies that baggage handling possesses a dual role: as a component in shaping service quality perceptions and as a direct driver of satisfaction. For LCC managers, this finding underscores the importance of managing baggage handling as a strategic service touchpoint, with practical implications including investment in automated baggage systems, real-time tracking technology, and staff training programs to effectively enhance passenger satisfaction and competitive advantage.

Abstract

The process of product returns from suppliers is very urgent to reduce large company losses due to products returned from suppliers experiencing many problems. This study aims to measure the supply chain performance in each backflow supply chain of telecommunication industry products in Indonesia. Analysis was conducted using the SCOR model and determination of value weighting using AHP. The results of the analysis with 10 indicators for the delivery and return process show that the total value of PT. XYZ's company performance is still far from the target. This indicator must be corrected because there is a need for an increase in company performance, namely the Delivery and Return indicators, one of which occurs in returns when the driver brings damaged goods taken from the supplier and repackages, or commonly called repackaging, the damaged product in the PT. XYZ warehouse. There is a shortage[A1] [A2] or lagging of some of these products. The results of the analysis also show that PT. XYZ has the lowest performance value on both criteria, namely delivery and return, where each of these values can be categorized as "poor" or can also be called bad. With this finding, what must be done to improve performance is the addition of Quality Control management so that the product you want to return or return for the repair process can be managed such that there is no shortage of product returns, does not take a long time, and does not cost much more money during the delivery process.

Abstract

One of the manufacturing companies engaged in agribusiness, one of which is processing cooking oil, often occurs damage to goods due to excess stock of goods and increases expenses for storage costs. Before carrying out the production process, the company must forecast demand to find out how much the estimated raw material needs will be used as inventory control so that there is no excess or shortage of stock that will harm the company. The purpose of this study is to predict the amount of cooking oil demand in the next 12 periods, plan the lot size of raw materials with the lowest cost and determine the right time to order raw material supplies. The method used in forecasting is Autoregressive Integrated Moving Average (ARIMA) and lot size planning with Materials Requirements Planning (MRP) FOQ and POQ techniques. ARIMA forecasting results with a MAPE value of 33% and the lowest cost technique chosen by POQ

Abstract

Purpose: This study investigates how Ease of Use in an e?procurement system impacts User Loyalty within a national upstream oil and gas company, with User Satisfaction serving as a mediating factor. The aim is to clarify the indirect effect of system usability on loyalty by evaluating the mediation pathway through satisfaction Methodology: Employing a quantitative approach, data were collected from 296 e?procurement users across 15 national hulu migas companies using structured surveys. Responses were analyzed using Structural Equation Modeling (SEM) via SmartPLS 4 Results: The study found that ease of use significantly impacts user satisfaction (? = 0.779, p < .000) and user loyalty (? = 0.293, p < .000), with user satisfaction mediating the relationship between ease of use and loyalty (indirect effect = 0.537, p = .000). These results align with recent research indicating that ease of use enhances user satisfaction and loyalty, with satisfaction serving as a mediator in this relationship. Conclusions: Ease of use significantly effect on user satisfaction and loyalty. User satisfaction has positive and significant mediating ease of use and loyalty. Limitations: The study does not account for variations across different platforms or consider deeper system factors such as security, technical complexity, and usability challenges—issues highlighted in the literature as significant barriers to e-procurement adoption Contribution: This Research contributes to both management practice and academic understanding by showing that improving system usability can enhance loyalty through user satisfaction—offering a clear direction for strategic enhancements in e?procurement platforms.
