Abstract

Indonesia, particularly Bandung Regency, faces significant flood risks that disrupt livelihoods and damage infrastructure. This study identifies the optimal locations and number of evacuation centers using the Set Covering Problem (SCP) model, integrating geographic data, population density, accessibility, and infrastructure capacity. The study applied constraints including a 1,000-meter maximum service distance, minimum road width of 6 meters for Class IIIB and IIIC access, shelter capacity limits, and full coverage of demand points. Using ArcGIS 10.2.1, candidate locations were evaluated by overlaying flood vulnerability maps with accessibility and facility data. Environmental sustainability was addressed by selecting sites with minimal ecological disruption, avoiding sensitive zones, and reusing existing structures to reduce land conversion. Results show that five centralized shelters in high-density, well-connected areas can cut evacuation travel time by up to 20% compared to dispersed locations. This integrated approach improves response efficiency, ensures access for vulnerable populations, and supports sustainable site planning. The findings contribute to disaster logistics theory and offer practical, replicable guidance for policy in other flood-prone regions.

Abstract

The aircraft spare parts supply chain is highly complex and vulnerable to delivery delays that may trigger Aircraft on Ground (AOG) conditions and increase operational costs. This study aims to analyze the characteristics of the aircraft spare parts supply network and to model delivery delay patterns in the repair process using a data-driven machine learning approach. The dataset consists of 4,962 shipment records with variables including delivery status (on-time/delay), ship vendor, origin point, destination point, lead time, and lead time category. Three classification algorithms, namely Decision Tree, Random Forest, and Logistic Regression, are applied to build and compare delay prediction models. The research stages comprise data preprocessing, splitting data into training and testing sets, model development, and performance evaluation using accuracy, precision, recall, and F1-score metrics. The results indicate that operational variables in the supply chain significantly influence delivery status and that the Random Forest model provides the best performance in capturing complex and non-linear delay patterns. These findings offer a basis for developing predictive decision support systems to mitigate delivery risks and enhance the reliability of Maintenance, Repair, and Overhaul (MRO) processes in the aviation industry.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh manajemen logistik dan kompetensi sumber daya manusia terhadap loyalitas pelanggan melalui kinerja logistik pada PT Pos Indonesia Kantor Cabang Kendal. Penelitian menggunakan pendekatan kuantitatif dengan metode survei melalui penyebaran kuesioner kepada pelanggan. Analisis data dilakukan menggunakan metode Structural Equation Modeling berbasis Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa manajemen logistik dan kompetensi sumber daya manusia berpengaruh positif dan signifikan terhadap kinerja logistik. Selanjutnya, kinerja logistik berpengaruh positif dan signifikan terhadap loyalitas pelanggan. Selain itu, manajemen logistik dan kompetensi sumber daya manusia juga berpengaruh terhadap loyalitas pelanggan baik secara langsung maupun tidak langsung melalui kinerja logistik sebagai variabel mediasi. Temuan ini menunjukkan bahwa peningkatan pengelolaan logistik dan kompetensi sumber daya manusia dapat meningkatkan kinerja logistik serta memperkuat loyalitas pelanggan.
