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

Rice procurement strategies play a crucial role in ensuring supply availability and stabilizing prices in traditional markets, particularly during critical periods characterized by higher demand and limited supply. This study aims to implement a rice procurement method in traditional markets in Tangerang Regency, using system dynamics during critical periods. This study uses an AnyLogic-based simulation approach, utilizing secondary data on rice prices, stock availability, and rice demand sourced from the Tangerang Regency Food Information System and the Tangerang Regency Agriculture and Food Security Office. Simulations were conducted in four different scenarios: standard conditions in May 2025, the period after Eid al-Adha in July 2025, the dry season with decreased food distribution in September 2025, and the Christmas and New Year season in December 2025. The results show that the period after Eid al-Adha is the most critical scenario, with the largest stock deficit of 12,146 and the lowest service level of 89.88%. Based on simulation findings and risk assessments, a mixed procurement strategy emerged as the most effective option to ensure stock availability, mitigate the risk of supply deficits, and facilitate future rice price stability during critical times.

Abstract

The transition toward electric vehicles has encouraged logistics companies to empirically evaluate operational cost efficiency as part of sustainable transportation strategies. This study aims to analyze the effect of using electric blind vans on energy operational costs and vehicle maintenance costs through operational cost efficiency at PT. Dapensi Dwikarya, a logistics company operating in Indonesia. This research employs a quantitative explanatory approach using a survey method to examine the causal relationships among variables. Data were collected through structured questionnaires measured on a seven-point Likert scale and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The analysis involves four main constructs: the use of electric blind vans, operational cost efficiency, energy operational costs, and vehicle maintenance costs. The results indicate that the use of electric blind vans has a positive and significant effect on operational cost efficiency. Furthermore, operational cost efficiency significantly affects both energy operational costs and vehicle maintenance costs. The findings also show that operational cost efficiency mediates the relationship between the use of electric blind vans and operational costs. Specifically, operational cost efficiency partially mediates the effect of electric blind van usage on energy operational costs and fully mediates its effect on vehicle maintenance costs. These results suggest that the economic benefits of adopting electric vehicles in logistics operations depend not only on vehicle technology but also on effective operational cost management to achieve long-term cost efficiency
