Abstract

Pertumbuhan jumlah kendaraan di area pusat perbelanjaan seperti mall menimbulkan permasalahan baru dalam pengelolaan lahan parkir. Pengunjung sering kesulitan menemukan slot parkir kosong, terutama pada waktu-waktu sibuk. Penelitian ini bertujuan untuk menganalisis pola parkir kendaraan di mall menggunakan metode klasterisasi Density-Based Spatial Clustering of Applications with Noise (DBSCAN). DBSCAN dipilih karena kemampuannya mengidentifikasi kelompok data berdasarkan kepadatan tanpa memerlukan jumlah klaster yang telah ditentukan sebelumnya. Data yang digunakan mencakup informasi durasi parkir, jenis kendaraan, status member, dan koordinat lokasi parkir. Tahapan penelitian meliputi eksplorasi data, visualisasi, normalisasi fitur spasial, penerapan algoritma DBSCAN, serta analisis hasil klasterisasi. Hasil dari proses klasterisasi menghasilkan beberapa kelompok kendaraan yang memiliki karakteristik berbeda, baik dari segi posisi parkir maupun durasi. Analisis lanjutan menunjukkan adanya konsentrasi kendaraan di area tertentu yang dapat menjadi dasar pengambilan keputusan untuk optimalisasi manajemen parkir, seperti penempatan petugas atau papan informasi digital. Penelitian ini membuktikan bahwa DBSCAN mampu mengidentifikasi pola parkir secara efektif, bahkan dalam kondisi distribusi kendaraan yang tidak seragam. Dengan demikian, pendekatan ini dapat menjadi solusi berbasis data dalam meningkatkan efisiensi dan kenyamanan pengelolaan parkir di mall. Temuan ini diharapkan dapat diadopsi oleh pengelola mall atau pengembang sistem informasi parkir untuk mendukung pengambilan kebijakan berbasis analisis spasial.

Abstract

The traditional Back-propagation algorithm has several weaknesses, including long training times and significant iterations to achieve convergence. This study aims to optimize traditional Back-propagation using the cyclical rule method to cover these weaknesses. Optimization is done by changing the training function and standard Back-propagation parameters using the training function and cyclical rule parameters. After that, a comparison of the two results will be carried out. This study uses quantitative method of time-series data on coronavirus cases sourced from the Worldometer website, then analyzed using three forecasting models with five input layers, one hidden layer (5, 10, and 15 neurons) and one output layer. The results showed that the 5-10-1 model with the training function and cyclical rule parameters and the tansig and purelin activation functions could perform well in optimization, including faster training time and smaller iterations (epochs), MSE training performance, and better tests. Low and high accuracy (92%) with an error rate of 0.01. So it was concluded that the training function and cyclical rule parameters with the tansig and purelin activation functions were able to optimize the traditional Back-propagation method, and the 5-10-1 model could be used for forecasting active cases of the coronavirus in Asia

Abstract

Excessive fat accumulation that impairs personal health and raises the risk of chronic diseases is the hallmark of obesity, a global health issue. Decision Tree (DT) has been widely used for obesity classification, but it tends to suffer from overfitting and poor performance on imbalanced datasets. To overcome these limitations, this study proposes an optimization of the Support Vector Machine (SVM) algorithm using Synthetic Minority Over-sampling Technique (SMOTE) and Hyperparameter Tuning. SMOTE was applied to balance the class distribution, whereas Grid Search was utilized to determine the optimal combination of hyperparameters (C, gamma, and kernel). The dataset employed in this research comprises multiple features related to individual health and lifestyle, with obesity level as the target class. The experimental results demonstrate that the optimized SVM model demonstrated strong classification performance, attaining 97% in accuracy, precision, recall, and F1-score. This high performance is significant because it enables more accurate early detection of obesity risk, which can support timely medical intervention and personalized treatment planning, ultimately contributing to better public health outcomesThese findings suggest that incorporating SMOTE and Hyperparameter Tuning substantially improves SVM performance, establishing it as a robust approach for obesity classification and early risk detection.

Abstract

Glaucoma is a chronic eye disease that can potentially cause permanent blindness if not detected early. This study aims to improve the generalization capability and reliability of glaucoma classification by optimizing the EfficientNetB0 architecture based on a Convolutional Neural Network (CNN). Optimization was carried out by applying double dropout (0.4 and 0.3) and adding a Dense layer with 128 ReLU-activated neurons to reduce overfitting and strengthen non-linear feature representation. The dataset used consists of 1,450 fundus images (899 glaucoma and 551 normal) obtained from IEEE DataPort. Model performance evaluation was performed using accuracy, precision, recall (sensitivity), specificity, F1 score, and Area Under the Curve (AUC) metrics, complemented by confusion matrix analysis to assess overall classification performance. The results showed that the optimized EfficientNetB0 model consistently outperformed the baseline comparison model with the highest accuracy, precision, recall (sensitivity), specificity, F1 score, and AUC values ​​of 95%. Based on the system performance results obtained, the Proposed model can be used as an aid for medical personnel in classifying glaucoma conditions so that they can provide appropriate medical treatment and reduce the risk of permanent blindness due to glaucoma.
