Analisis Kinerja Multimodal Dense Neural Network untuk Deteksi Hipoksia Janin pada Dataset Tidak Seimbang
No full textThis study aims to develop a Multimodal Dense Neural Network (MDNN) for detecting fetal hypoxia using an imbalanced Cardiotocography (CTG) dataset. The primary challenges in fetal hypoxia diagnosis include the imbalance between Normal, Suspect, and Hypoxia classes and the limited interpretability of conventional deep learning models. To address these issues, a robust preprocessing pipeline was designed, consisting of Physiological Clipping (50–200 bpm), Median Absolute Deviation (MAD) normalization, SMOTETomek balancing, and Gaussian noise augmentation. The MDNN architecture integrates two parallel branches: Fetal Heart Rate (FHR) signals and clinical parameters (pH, Apgar score, and base deficit), fused through a Dense Fusion Layer to generate compact multimodal representations. Experimental results demonstrate that the proposed MDNN achieved 99.7% accuracy, 99.5% F1-score, and 0.993 AUC, outperforming CNN (84.6%), ResNet18 (82.3%), and MLP (87.5%). The confusion matrix showed good generalization capability with per-class accuracies of 69% (Normal), 56% (Suspect), and 67% (Hypoxia). SHAP feature importance analysis identified FHR pattern (0.45) and pH level (0.25) as the most influential features in classification. These findings confirm that the proposed MDNN is robust, computationally efficient, and clinically interpretable, making it a promising framework for real-time fetal hypoxia diagnosis in modern clinical environments

PENGARUH APLIKASI URIN SAPI SERTA JUMLAH RUAS TERHADAP PERTUMBUHAN STEK KOPI ROBUSTA (Coffea canepohora L.)
No full textThe cultivation of Coffea canephora (robusta coffee) in Indonesia has undergone substantial growth in recent years. Propagation of robusta coffee can be achieved through both vegetative and generative methods; however, vegetative propagation via stem cuttings is the most widely adopted technique among coffee farmers. The success of stem cutting propagation is influenced by various factors, including the number of nodes per cutting and the application of growth-stimulating substances such as cow urine. This study aimed to assess the effects of cow urine concentration and the number of stem nodes on the growth performance of robusta coffee cuttings. A factorial experiment was conducted using a Randomized Complete Block Design (RCBD) with two factors. The first factor was cow urine concentration at three levels: 30% (U1), 45% (U2), and 60% (U3). The second factor was the number of nodes per cutting: 3 nodes (R1), 4 nodes (R2), and 5 nodes (R3), with each treatment combination replicated three times. The results demonstrated that the combination of 30% cow urine and four-node cuttings significantly enhanced the percentage of successful establishment. Moreover, the 30% cow urine treatment significantly improved shoot emergence rate, shoot length, and stem diameter. In contrast, the 60% concentration only showed a significant effect on leaf length
