Abstract

The increasing number of vehicles on university campuses has led to significant congestion, particularly around parking areas. This study aims to design an intelligent parking route model using the Density-Aware A* algorithm to minimize vehicle congestion within the Faculty of Science and Technology (FST) at UIN North Sumatra. The proposed approach represents the internal campus network as a weighted graph, where each edge integrates both spatial distance and a density penalty that reflects the occupancy-to-capacity ratio of each parking area. The algorithm was implemented and simulated using Python and the NetworkX library within Google Colab. The results show that the system accurately identifies the optimal parking route based on vehicle type and real-time occupancy data. For motorcycles, the optimal path is A > B > F with a total cost of 23.06, while for cars, the most efficient path is A > B > H with a total cost of 18.21. The findings indicate that incorporating density-based cost adjustments effectively balances travel efficiency and vehicle distribution, contributing to overall congestion reduction in the FST–FKM corridor. Future research should focus on integrating live sensor data and adaptive feedback mechanisms to support large-scale deployment across diverse campus environments.

Abstract

Efficient workload scheduling in heterogeneous distributed systems remains a complex challenge due to variations in computing capacities and unpredictable task arrivals. Traditional scheduling algorithms, including conventional Particle Swarm Optimization (PSO), often suffer from premature convergence and limited adaptability under dynamic workload conditions. To address these limitations, this study proposes an Adaptive Particle Swarm Optimization (APSO) algorithm that dynamically adjusts the inertia weight parameter to maintain an effective balance between exploration and exploitation during the search process. The adaptive mechanism allows particles to respond more effectively to workload fluctuations and prevents stagnation in local optima. Experiments were conducted on a simulated heterogeneous cluster environment consisting of multiple computing nodes with varying processing speeds and workloads. The performance of the proposed APSO was evaluated using three primary metrics: makespan, CPU utilization, and load imbalance. The results demonstrate that APSO successfully reduced makespan from 350.0 s to 287.0 s, achieving an improvement of approximately 18%, and increased CPU utilization from 77.8% to 83.4% compared to the Round Robin baseline. These findings confirm that the adaptive parameter control significantly enhances scheduling efficiency, improves resource utilization, and provides a more robust and reliable solution for dynamic heterogeneous distributed systems.

Abstract

Optimal selection of elective courses plays an important role in supporting students’ academic success and ensuring alignment between learning interests and final project preparation. This study aims to develop a favorite course search system based on the A-Star (A*) algorithm by utilizing students’ average grades as the main evaluation variable. The system was implemented using the Java NetBeans platform, supported by datasets consisting of course names, credit weights (SKS), and grade distributions. The A* algorithm was adapted through the integration of heuristic components, including Standard Deviation and Relative Credit Load, to improve accuracy in identifying optimal course recommendations. Experimental results demonstrate that the system is capable of generating recommendations with an accuracy rate of 95%, verified through comparison between system outputs and manual calculations. The results also show that the Mitigation course ranked highest with a score of 6.1, indicating strong student performance in that subject. Overall, the system provides a practical and efficient solution for academic decision-making, enabling students to select elective courses more strategically based on data-driven insights. This study contributes to the development of computational methods in educational recommendation systems and opens opportunities for further enhancement through integration with real academic databases.

Abstract

Weather variability creates substantial uncertainty in rice production and distribution, often resulting in discrepancies between predicted harvest quantities and logistical capacity. To address this challenge, this study presents an integrated framework that combines Bayesian weather prediction, climate-based rice yield estimation, and automated distribution simulation to support more reliable and uncertainty-aware agricultural planning. The Bayesian model is employed to generate probabilistic forecasts for key climatic variables rainfall, temperature, and humidity by producing posterior distributions that capture the inherent variability of environmental conditions, yielding stable predictive performance with an RMSE of 0.84 for rainfall and 0.62 for temperature. These probabilistic forecasts are subsequently utilized within a regression-based yield estimation model to quantify the influence of climatic fluctuations on harvest output, resulting in a mean absolute percentage error (MAPE) of 6.7%, which demonstrates strong consistency with actual production data. The estimated yields are then incorporated into an automated distribution simulation constructed as a weighted directed graph, where Dijkstra’s algorithm is applied to determine optimal delivery routes by evaluating distance, predicted load, and weather-related uncertainty. Simulation results reveal improvements in route efficiency and reduced deviation in travel times across varying climatic scenarios. Overall, the integration of Bayesian inference, yield prediction, and automated routing forms an adaptive and robust decision-support system for rice distribution management, offering a more reliable approach to optimizing agricultural logistics in environments characterized by dynamic and unpredictable weather patterns.

Abstract

Stunting remains a national priority issue in Indonesia, and West Aceh Regency is one of the regions facing this challenge. The success of stunting reduction programs heavily depends on effective and well-targeted budget allocation. This study aims to develop a budget allocation simulation model for stunting reduction programs in West Aceh Regency using Multiple Linear Regression. Historical program and budget data from the template-data-kabupaten-aceh-barat-stunting.csv dataset were used to train the model. Features such as year, program category (Infrastructure, Empowerment, Health, Other), program name, and a priority score were analyzed to predict the budget amount. The model fitting results show very high performance, with an Adjusted R-squared of 0.989 and an F-statistic of 298.6 (p < 0.001), indicating the model significantly explains the variability in budget allocation. The prioritas (priority) variable was found to be the most statistically significant predictor (p = 0.000). This model was then used to simulate an optimal budget allocation for 2025, with a total recommended budget of IDR 36.50 Billion. The main recommendation focuses on the "Program for Fulfilling Health Efforts" with a simulated allocation of IDR 33.75 Billion. This research demonstrates the potential of predictive modeling as a data-driven decision-making tool for local governments in planning budgets for stunting interventions. Furthermore, this study underscores the critical importance of shifting from historical-based budgeting to evidence-based allocation methods to accelerate national stunting reduction goals effectively.
