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.

Abstract

Fast and efficient service is a crucial element in maintaining customer satisfaction and loyalty to banking institutions. One issue commonly faced by banks is long queues during busy times, which results in increased waiting times and a decline in service quality. The purpose of this study is to examine the performance of the queueing system in bank customer service by utilizing a discrete simulation approach based on the M/M/1 model. This model describes a system with one server, with exponentially distributed arrival and service times, and a random customer arrival rate. In this study, 50 simulations were conducted with variations in arrival rate (λ) and service rate (μ) to gain a comprehensive understanding of the overall system performance. The parameters examined included the average customer waiting time in the queue, the total time customers spent in the system, and the proportion of server utilization. The results of the simulation show that when the arrival rate approaches the service rate (λ → μ), the waiting time increases significantly and the system utilization rate reaches almost 100%. The average customer waiting time was recorded at between 2 and 3 minutes, with a server utilization rate of around 80-85%. In conclusion, the queueing system at banks continues to function well, but there is room for improvement in performance by increasing the number of tellers or improving service times. The findings of this study indicate that discrete simulation can be a powerful tool in analyzing and improving service efficiency for customers in the banking industry.

Abstract

Infectious diseases pose a significant public health challenge in the Madura region, necessitating a clear understanding of their transmission dynamics for effective control strategies. This study aims to apply the Susceptible-Infected-Removed (SIR) model to comparatively analyze the transmission dynamics of five major infectious diseases in Madura-Tuberculosis (TB), Leprosy, HIV, Dengue Fever, and COVID-19 using 2023 case data. A quantitative, comparative modeling approach was employed using data from 18 sub-districts, involving descriptive/spatial analysis, inter-disease correlation, and dynamic SIR modeling to estimate epidemiological parameters (transmission rate , recovery rate $\gamma$) and the Basic Reproduction Number (R0). Intervention scenarios were also simulated for TB. The results identified Tuberculosis as the predominant health burden (1,641 total cases), spatially concentrated in hotspots like Bangkalan sub-district (249 cases). All five diseases showed epidemic potential (R0 > 1), with HIV exhibiting the highest R0 (10.0) due to its extremely low recovery rate (  =0.01$), followed by TB and Leprosy (R0=4.0) COVID-19 (R0=3.33), and Dengue Fever (R0=1.50). A strong positive correlation (0.84) was found between TB and HIV cases at the sub-district level. Intervention simulations for TB demonstrated that a 50% reduction in the transmission rate ( ) could reduce the peak infection load by over 60%. This study concludes that while TB is the largest case burden, HIV has the highest epidemic potential, and their strong correlation necessitates integrated, spatially-targeted (sub-district level) control strategies.

Abstract

Using the Extreme Gradient Boosting (XGBoost) algorithm with the Lifestyle and Wellbeing dataset from the Kaggle platform, this study attempts to categorize healthy lifestyle patterns. The growing incidence of undesirable behaviors that have a direct impact on people's health and well-being, like stress, inactivity, and a poor work-life balance, is what spurred the research. Using 500 randomly chosen data samples that cover a range of behavioral and psychological lifestyle variables, the study uses a quantitative computational method. Data cleaning, standardization, and target label generation using a health index, which is computed as the mean of positive variables less the mean of negative variables, are all included in the preprocessing stage. With n_estimators = 100, learning_rate = 0.1, and max_depth = 4, the XGBoost model was trained using Python in the Google Colab environment. According to the results, the model's accuracy was 97%, and its precision, recall, and F1-score were all balanced. SLEEP_HOURS, DAILY_STRESS, and WORK_LIFE_BALANCE_SCORE are the most significant factors in predicting a healthy lifestyle, suggesting that psychological stability and sufficient rest are important factors in determining general well-being. As a basis for creating adaptive healthy lifestyle recommendation systems and future research incorporating physiological data from wearable devices to improve prediction accuracy, the study concludes that XGBoost successfully classifies lifestyle patterns and offers comprehensible insights into behavioral factors that contribute to health.

Abstract

This study aims to develop a classification model for determining service priority levels in administrative processes at the Ministry of Religious Affairs of North Tapanuli by examining the effectiveness of the Naïve Bayes algorithm in processing categorical service data. A simulated dataset of 200 service request records reflecting common administrative characteristics was created using a quantitative technique. Preprocessing, feature encoding, and train-test splitting were then performed before modeling with the Multinomial Naïve Bayes classifier. Accuracy, precision, recall, and f1-score were used to assess the model's performance; confusion matrix analysis and visualization were also used. The findings demonstrate that Naïve Bayes attained an accuracy of 78%, which is in line with earlier research showing the algorithm's competitive performance on categorical and public service datasets. These results suggest that administrative data with simple feature distributions can benefit from probabilistic models like Naïve Bayes. The paper indicates that Naïve Bayes can be used as a decision-support tool for administrative service prioritization and suggests further research to improve forecast reliability using actual operational data and algorithm comparison.

Abstract

Malaria remains a public health challenge in Indonesia, including in Central Java Province, which still has areas with active transmission. This study aims to map malaria risk zones and simulate elimination time estimates using a hybrid K-Means clustering approach and an exponential decay model. Malaria case data from 2023 from 35 districts/cities were analyzed to identify regional clusters based on case burden. The clustering results showed three risk zones, with four areas Pati, Blora, Purworejo, and Semarang City included in the Red Zone, which accounted for 37.7% of total cases. Next, elimination simulations were conducted in the Red Zone using two scenarios: (1) Business as Usual with a 10% reduction in cases per year and (2) Accelerated Intervention with a 40% reduction per year. Modeling results showed that the first scenario would only achieve elimination after 2080, while the second scenario would enable elimination to be achieved around 2034. These findings emphasize the importance of targeted and intensive interventions in priority areas to accelerate the achievement of malaria elimination targets in Central Java.
