Abstract

Purpose: This study aims to compare the economic and financial feasibility of electric vehicles (EVs) and conventional vehicles (CVs) in tertiary distribution operations at PT Pos Indonesia, focusing on two operational units: KCU Karawang and KCU Cirebon. Methods: A quantitative comparative approach was applied using Total Cost of Ownership (TCO) and investment appraisal indicators, including Net Present Value (NPV), Internal Rate of Return (IRR), Benefit–Cost Ratio (BCR), and Payback Period (PP). Operational data such as fuel consumption, maintenance, insurance, tax, and depreciation were analyzed under a five-year economic life cycle. Results: The findings show that EVs consistently outperform CVs across all major financial indicators. EVs reduce annual energy costs by up to 80%, significantly lower maintenance and tax expenses, and generate positive NPV values in both locations. IRR for EVs exceeds the 5% discount rate—9.35% in Karawang and 11.2% in Cirebon—while BCR values remain above 1. Payback periods for EVs are 4.4 years in Karawang and 4.3 years in Cirebon. Conversely, CVs show negative NPV, BCR < 1, and no recoverable payback period. Implications: The results highlight the strong financial viability of adopting EVs within Indonesia’s logistics sector, supporting strategic fleet electrification for long-term cost efficiency. The findings also reinforce national sustainability policies promoting low-carbon transportation and provide evidence-based insights for future investment decisions in logistics operations.

Abstract

An airport is a facility where all stakeholders in the aviation industry converge, and its core product is “service,” which includes services for passengers, cargo, and aircraft. Customer satisfaction at airports is an essential outcome that must be delivered to all aviation industry stakeholders. This study aims to analyze the influence of service quality and marketing mix on customer trust, with customer satisfaction serving as an intervening variable at the airport. In reality, many airport service users still feel dissatisfied with both the services provided and the existing facilities. This is evident from various complaints submitted by users, indicating that they have not yet experienced satisfactory airport services. This research employs a quantitative method by distributing questionnaires to 100 respondents, consisting of domestic passengers at Minangkabau International Airport. The findings reveal that service quality and marketing mix have a significant partial and simultaneous effect on customer satisfaction. Furthermore, service quality, marketing mix, and customer satisfaction—both partially and simultaneously—have a significant influence on customer trust. However, the customer satisfaction variable is unable to mediate the relationship between service quality and the marketing mix toward customer trust.

Abstract

This study aims to optimize multichannel book distribution efficiency through the integration of machine learning–based demand forecasting and centralized warehouse strategy at PT Mizan Media Utama. Using three years of multichannel sales data from offline stores, marketplaces, resellers, and events, the research employs the XGBoost algorithm to predict monthly demand for selected book SKUs. The results demonstrate that XGBoost consistently outperforms conventional forecasting methods, achieving lower Root Mean Square Error (RMSE), Mean Absolute Percentage Error (MAPE), and higher R² values, indicating improved accuracy and reliability. Comparative analysis between actual sales in 2025 and forecasted results shows that XGBoost reduces average forecast error by 20–30% compared to traditional projection methods. These accurate predictions support more effective stock allocation within the centralized warehouse, minimizing overstock and stockout risks across sales channels. The findings confirm that integrating predictive analytics into distribution planning enhances operational efficiency, improves inventory control, and strengthens data-driven decision-making. This study contributes both theoretically and practically by demonstrating how machine learning can transform conventional supply chain management into a digitally integrated, responsive, and efficient system suited for the publishing and book distribution industry.

Abstract

In the global logistics landscape, optimizing import operations is critical to ensuring timely delivery and minimizing inefficiencies. This study proposes a hybrid clustering framework that integrates K-Means with Particle Swarm Optimization (PSO) to classify import logistics processes based on duration metrics. A data set comprising 344 real-world import records was analyzed, with pre-processing steps including RobustScaler normalization and outlier handling to improve data quality. The PSO algorithm was used to dynamically optimize the clustering parameters, leading to better segmentation of the logistics stages into performance-based clusters. Internal validation using the Silhouette Score (0.987), Davies-Bouldin Index (0.01), and Calinski-Harabasz Index (2450) confirmed the superior performance of K-Means over DBSCAN and Agglomerative Clustering. Principal Component Analysis (PCA) further visualized the separation between fast and slow process groups. The findings reveal that the delivery stage represents the most significant bottleneck, with durations exceeding 700 days in slower clusters. The proposed method offers actionable insights for logistics managers to improve operational efficiency, reduce lead time variability, and implement data-driven process improvements.

Abstract

This study aims to develop and validate a centralised procurement model in the construction industry using Exploratory Factor Analysis (EFA) and Partial Least Squares Structural Equation Modelling (PLS-SEM). The EFA results identified six new factors representing the multidimensional nature of centralised procurement: ORCHESTRA, STRATEGUS, DIGISONIC, FINCERTO, SYMPHONY-LINK, and GRAND-GOVERNANCE. All constructs showed strong statistical validity and reliability. The PLS-SEM findings showed high explanatory power, with R² values of 0.732 for SYMPHONY-LINK and 0.731 for GRAND-GOVERNANCE. These results highlight that STRATEGUS significantly influences SYMPHONY-LINK, while SYMPHONY-LINK is the dominant predictor in procurement governance. Furthermore, SYMPHONY-LINK fully mediates the effect of STRATEGUS on GRAND-GOVERNANCE, highlighting cross-functional integration as a critical driver of centralised procurement success. This study contributes theoretically by introducing new constructs into the domain of centralised procurement and provides practical implications for construction companies seeking standardised, transparent, and sustainability-oriented procurement strategies.
