Abstract

Heart disease is a leading cause of mortality worldwide and its rising prevalence challenges health systems. This study evaluates Decision Tree, k Nearest Neighbors, and Random Forest using the Heart Failure Prediction Dataset from Kaggle with 918 records and 12 demographic, clinical, and lifestyle features. The target variable indicates the presence of heart disease. Data preprocessing included cleaning, transformation, and scaling. Hyperparameters were tuned with stratified five fold cross validation to prevent data leakage. Performance was assessed using accuracy, precision, recall, F1 score, ROC AUC, PR AUC, Matthews Correlation Coefficient, and Brier score each estimated with 95 percent confidence intervals via bootstrap. k Nearest Neighbors achieved the highest accuracy at 90.2 percent, followed by Random Forest at 87.5 percent and Decision Tree at 85.3 percent. Calibration and decision curve analyses indicated that k Nearest Neighbors and Random Forest provided better calibrated probabilities and higher clinical utility across plausible thresholds. The study offers a reproducible evaluation pipeline and supports the use of machine learning for early detection of heart disease while encouraging future work on larger datasets and more advanced models.

Abstract

This study investigates the performance of Convolutional Neural Network (CNN) architectures enhanced with Convolutional Block Attention Module (CBAM) for Indonesian banknote classification. Although attention mechanisms have shown strong potential in improving fine-grained visual recognition, their effectiveness for the classification of banknotes with fine textures and similar color patterns remains underexplored, forming a key research gap addressed in this work. Four architectures, ResNet50, ResNet50+CBAM, MobileNetV2, and MobileNetV2+CBAM, were evaluated using K-Fold cross-validation on a dataset of 1,281 images representing seven banknote denominations. Experimental results show that ResNet50 achieves strong baseline performance with a weighted Train accuracy of 99.14% and a Val accuracy of 96.72%, while the integration of CBAM further improves feature discrimination, with ResNet50+CBAM obtaining the highest average accuracy across all folds with a weighted Train accuracy of 100% and a Val accuracy of 99.45%. MobileNetV2 showed lower performance due to its lightweight capacity with a Train accuracy of 91.88% and a decrease in Val accuracy of 85.71%. However, the addition of CBAM provided measurable improvements and greater stability with a Train accuracy of 99.61% and Val accuracy of 92.82%. Overall, CBAM improved CNN’s ability to focus on spatial information and salient channels, resulting in more reliable classification. ResNet50+CBAM emerged as the best-performing model, offering the best balance between accuracy and consistency. These findings support the development of reliable computer vision systems for financial technology applications, including automatic banknote recognition, counterfeit detection, and secure transaction verification.

Abstract

Struktur bangunan dengan konfigurasi denah yang tidak beraturan, seperti berbentuk T, L, U, dan H, cenderung memiliki respons dinamik yang kompleks ketika mengalami beban gempa. Ketidakberaturan tersebut dapat meningkatkan konsentrasi gaya dan deformasi, sehingga berpotensi menimbulkan kerusakan struktural. Salah satu upaya untuk mengurangi pengaruh ketidakberaturan adalah dengan menerapkan konsep dilatasi bangunan, yaitu memisahkan massa bangunan menjadi beberapa segmen yang lebih sederhana. Namun, penerapan dilatasi juga menimbulkan risiko terjadinya pounding atau benturan antar bangunan akibat perbedaan respons dinamik selama gempa. Penelitian ini membahas analisis respons struktur gedung bertingkat dengan denah berbentuk L yang menerapkan konsep bangunan dilatasi, khususnya terhadap potensi terjadinya pounding. Tujuan utama penelitian ini adalah untuk menentukan nilai perpindahan (displacement) relatif antar bangunan yang berdekatan ketika struktur dikenai beban gempa dinamis. Metode analisis yang digunakan adalah Linear Time History Analysis dengan mempertimbangkan tiga rekaman gempa nyata, yaitu Imperial Valley-06, Iwate_off, dan Vina Del Mar Centro. Ketiga data gempa tersebut terlebih dahulu disesuaikan (matching) terhadap spektrum respons rencana agar sesuai dengan kondisi seismik lokasi studi. Hasil analisis menunjukkan bahwa struktur gedung yang dikenai ketiga beban gempa dinamis mengalami perpindahan yang cukup signifikan sehingga menyebabkan terjadinya benturan antar segmen bangunan dilatasi. Hal ini mengindikasikan bahwa jarak pemisah antar bangunan belum mampu mengakomodasi respons dinamik yang terjadi. Penelitian ini memberikan gambaran mengenai pentingnya evaluasi displacement dan potensi pounding pada bangunan berdilatasi. Penelitian lanjutan disarankan menggunakan Nonlinear Time History Analysis untuk memperoleh gambaran respons inelastis struktur yang lebih mendekati kondisi aktual.

Abstract

The program purposed to enhance the capacity and independence of fishermen in processing marine products sustainably, healthily, and with added value. Through the application of natural preservation technology, marine products are processed using biopreservative materials derived from local aquatic agricultural resources, thereby extending shelf life without reducing nutritional quality. The program also emphasizes the integration of fisheries, aquatic agriculture, and nutritional aspects to produce high-quality food products and support food security in coastal communities. The implementation methods include socialization, training, production assistance, and evaluation of technology application. The outcomes demonstrate a transformation of the Raja Pulau fishermen’s group toward innovative, environmentally friendly, and market-oriented agroindustry. Significant improvements are reflected in product diversification, the development of functional products, and the group’s ability to produce alternatives beyond fresh fish. The use of ice as a preservative has also been substituted with natural alternatives such as gambier, carrageenan, torch ginger, and chitosan, which the community has learned to apply. These innovations not only improve fishermen’s knowledge and skills but also contribute to increased income. The products developed through this program have been marketed both within Bengkulu and beyond, providing tangible contributions to strengthening the blue economy based on local wisdom and supporting the vision of Golden Indonesia 2045
