Abstract

Kualitas udara merupakan faktor penting yang berdampak langsung terhadap kesehatan manusia dan lingkungan. Peningkatan aktivitas industri, transportasi, dan urbanisasi menyebabkan konsentrasi polutan udara semakin tinggi, sehingga diperlukan metode klasifikasi kualitas udara yang akurat sebagai dasar pengambilan keputusan. Penelitian ini bertujuan untuk meningkatkan performa algoritma Random Forest dalam mengklasifikasikan kualitas udara berdasarkan Indeks Standar Pencemaran Udara (ISPU) melalui optimasi hyperparameter menggunakan Genetic Algorithm (GA). Dataset yang digunakan berupa data kualitas udara harian wilayah Tangerang Selatan periode 2020–2022, dengan enam parameter polutan utama yaitu PM2.5, PM10, SO₂, CO, O₃, dan NO₂, serta tiga kategori kualitas udara: Good, Moderate, dan Unhealthy. Tahapan penelitian meliputi preprocessing data, pembagian data secara stratified, pelatihan model Random Forest baseline, optimasi hyperparameter menggunakan GA, serta evaluasi performa model. Hasil penelitian menunjukkan bahwa optimasi menggunakan Genetic Algorithm mampu meningkatkan akurasi pengujian dari 81,73% menjadi 82,23% serta mengurangi indikasi overfitting pada model. Analisis feature importance menunjukkan bahwa CO dan PM2.5 merupakan parameter paling berpengaruh dalam klasifikasi kualitas udara. Hasil ini membuktikan bahwa Genetic Algorithm efektif digunakan untuk mengoptimasi Random Forest dan meningkatkan akurasi klasifikasi kualitas udara berbasis ISPU.

Abstract

Accurate wind turbine power curve modeling plays a crucial role in performance evaluation, energy yield estimation, and data-driven control strategies. However, actual power curves often exhibit non-linear behavior influenced by atmospheric variability, measurement noise, and SCADA anomalies, making conventional modeling approaches less effective. This study proposes an optimized logistic power curve model whose parameters are tuned using Particle Swarm Optimization (PSO) to improve predictive accuracy. The analysis uses the Wind Turbine SCADA Dataset from Kaggle, which undergoes extensive preprocessing including physical rule filtering, outlier detection with the Interquartile Range (IQR) method, anomaly removal, and smoothing of the power signal. A three-parameter logistic model is selected due to its ability to capture the typical S-shaped relationship between wind speed and power output. PSO is applied to identify optimal model parameters by minimizing the Mean Squared Error (MSE), utilizing 40 particles over 200 iterations. The optimized model achieves strong predictive performance with RMSE of 404.09, MAE of 179.96, and R² of 0.904 on the test set, indicating that more than 90% of the variability in actual power can be explained by wind speed. Residual analysis reveals heteroscedastic patterns and slight overestimation in mid-range wind speeds, yet overall model consistency remains high. Comparative evaluation against Linear Regression, Random Forest, and logistic modeling using curve_fit shows that the Logistic–PSO approach provides the most accurate and stable predictions. These findings demonstrate that combining logistic modeling with PSO offers an effective and robust method for data-driven wind turbine power curve optimization.

Abstract

Chronic kidney disease is an increasingly prevalent health issue that requires more precise clinical data-based early detection methods to enable timely and appropriate treatment. This study focuses on developing a predictive model for chronic kidney disease using the Light Gradient Boosting Machine (LightGBM) algorithm and enhancing its performance through hyperparameter optimization with the Grey Wolf Optimizer (GWO). The dataset used originates from public sources and undergoes several preprocessing steps, including missing value imputation, categorical feature encoding, outlier handling, initial feature selection, and stratified data splitting to maintain model quality. Three modeling approaches were evaluated: LightGBM with default parameters, LightGBM enhanced using Random Search, and LightGBM optimized with GWO. The experimental results indicate that the baseline model already performs well, Random Search improves accuracy and F1-score, and GWO achieves the highest AUC-ROC value despite requiring longer computation time. Significance testing through cross-validation shows that the performance differences among the three models are not statistically significant, suggesting that the observed improvements are not strong enough to determine a definitively superior optimization method. The feature importance analysis highlights that clinical indicators such as creatinine levels, glomerular filtration rate, blood pressure, and urine protein contribute most prominently to the prediction. Overall, the study demonstrates that LightGBM is a reliable model for early detection of chronic kidney disease, and hyperparameter optimization still offers added value that can support the development of AI-based clinical decision-support systems

Abstract

Information system security faces serious challenges due to increasingly complex cyber attacks. Intrusion Detection Systems (IDS) require efficient approaches to handle high-dimensional data such as the NSL-KDD dataset with 41 features. This study aims to implement the Genetic Algorithm (GA) for feature selection on the NSL-KDD dataset to improve the efficiency and accuracy of network attack detection. The method used is computational experimental research, involving data preprocessing, GA implementation for feature selection, building a classification model using Random Forest, and performance evaluation based on accuracy, precision, recall, F1-score, and computation time. The results show that GA successfully reduced features from 41 to 12 features (70.7% reduction), significantly improving computational efficiency. However, model accuracy slightly decreased from 0.4973 to 0.4951, indicating that while GA is effective for feature selection, the elimination of certain features may reduce classification capability. The implication of this study is that GA can be used as a tool to simplify intrusion detection models, but it should be combined with parameter optimization and data imbalance handling to achieve more optimal performance.
