Abstract

The advancement of information retrieval systems has shifted from keyword-based approaches to semantic retrieval using transformer-based models such BERT and its variants. Despite their ability to capture contextual meaning, the vocabulary mismatch problem between queries and documents remains a key challenge. Query expansion (QE) is commonly used to address this issue, but its effectiveness in semantic retrieval is not always consistent. This study aims to analyze the impact of query expansion on a semantic retrieval system based on a fine-tuned IndoSBERT model using a dataset of undergraduate thesis titles and abstracts at repository UPN “Veteran” Jawa Timur. A hybrid QE approach is proposed by combining pretrained FastText and domain-specific Word2Vec embeddings, with and without filtering mechanisms. The system performance is evaluated using Precision@15, Recall@15, Mean Average Precision (MAP), and nDCG@15. The results show that QE can improve retrieval performance when properly controlled. The best performance is achieved by the hybrid QE with filtering, where MAP increases from 0.389 (without QE) to 0.483 and nDCG reaches 0.911. In contrast, FastText-based QE without filtering results in performance degradation due to query drift. It can be concluded that the effectiveness of QE in semantic retrieval is highly dependent on the quality of expansion terms and the application of filtering strategies. QE is not inherently beneficial, but requires careful design to improve retrieval performance.

Abstract

Penentuan prioritas penerima bantuan Rumah Tidak Layak Huni (RTLH) di Kabupaten Jombang masih dilakukan secara manual melalui survei lapangan dan verifikasi berjenjang, sehingga rentan terhadap subjektivitas dan ketidakkonsistenan dalam pengambilan keputusan. Penelitian ini mengusulkan penerapan algoritma Light Gradient Boosting Machine (LightGBM) yang dioptimasi menggunakan Bayesian Optimization, serta membandingkan performanya dengan Adaptive Neuro-Fuzzy Inference System (ANFIS) untuk mengklasifikasikan prioritas penerima bantuan RTLH secara otomatis dan objektif. Dataset yang digunakan berjumlah 9.173 data dari Dinas Perumahan dan Permukiman Kabupaten Jombang, mencakup 36 variabel yang meliputi karakteristik sosial-ekonomi keluarga dan kondisi fisik bangunan, dengan dua kelas target yaitu Prioritas dan Non-Prioritas. Tahap preprocessing meliputi data cleaning dengan penghapusan missing values, transformasi data kategorikal menggunakan label encoding, dan normalisasi Min-Max Scaler. Bayesian Optimization digunakan untuk menentukan konfigurasi hyperparameter optimal pada LightGBM. Hasil optimasi menghasilkan konfigurasi terbaik dengan n_estimators=446, learning_rate=0,3, num_leaves=75, max_depth=7, min_child_samples=26, dan reg_lambda=6,12. Model LightGBM dengan Bayesian Optimization berhasil mencapai akurasi 95%, presisi 96%, recall 96%, dan F1-Score 96% pada kelas Prioritas. Sementara itu, model ANFIS yang menggunakan 15 fitur terpilih menghasilkan akurasi 91%, presisi 93%, recall 92%, dan F1-Score 92%. Validasi pada data lapangan menunjukkan akurasi LightGBM sebesar 90,88%, membuktikan bahwa model layak diimplementasikan sebagai sistem pendukung keputusan.

Abstract

Penentuan developer yang tepat berdasarkan log aktivitas berupa teks tidak terstruktur merupakan tantangan penting dalam manajemen penugasan proyek. Penelitian-penelitian sebelumnya umumnya menggunakan Content-Based Filtering atau algoritma clustering konvensional seperti K-Means dan DBSCAN, yang memiliki keterbatasan dalam menangani data aktivitas developer yang padat. Penelitian ini mengusulkan pendekatan sistem rekomendasi yang mengintegrasikan Content-Based Filtering (CBF) dengan clustering berbasis kepadatan menggunakan HDBSCAN, yang  belum pernah diterapkan secara langsung dalam konteks rekomendasi developer berbasis log aktivitas. Log aktivitas direpresentasikan menggunakan TF-IDF dan direduksi dimensinya dengan UMAP, kemudian dikelompokkan menggunakan HDBSCAN tanpa memerlukan penentuan jumlah klaster di awal, sehingga lebih efektif dalam mengelola data aktivitas yang padat. Rekomendasi dihasilkan berdasarkan kedekatan jarak dalam klaster yang terbentuk. Evaluasi pada dataset yang terdiri dari 4.505 log aktivitas dan 45 data uji menunjukkan bahwa konfigurasi parameter min_cluster_size = 2 dan min_samples = 2 menghasilkan performa terbaik dengan nilai Hit Ratio sebesar 88,8%, Recall sebesar 80%, dan Mean Reciprocal Rank (MRR) sebesar 56,3%. Dibandingkan dengan pendekatan Content-Based Filtering saja, metode yang diusulkan menunjukkan peningkatan pada Hit Ratio dan Recall, yang mengindikasikan peningkatan cakupan dan relevansi rekomendasi developer.

Abstract

Low contrast variation, uneven intensity distribution, and the presence of noise in retinal fundus images pose major challenges for blood vessel segmentation, particularly regarding thin and complex structures. These conditions make it difficult for models to accurately distinguish between blood vessels and the background. This study aims to analyze the impact of contrast enhancement techniques on retinal blood vessel segmentation performance using a CAS-UNet architecture modified with Coordinate Attention (CA). The methodology involves three preprocessing scenarios: Grayscale, Grayscale + CLAHE, and Grayscale + CLAHE + Gamma Correction. The model was trained using the DRIVE and CHASE_DB1 datasets with an 80:20 data split, an SGD optimizer, a learning rate of 0.01, and a combined BCE and Dice loss function over 50 epochs. Evaluation was conducted using a confusion matrix based on accuracy, sensitivity, specificity, F1-score, and IoU metrics. The results indicate that the Grayscale + CLAHE combination yielded the best performance—achieving a sensitivity of 81.46%, an F1-score of 81.63%, and an IoU of 69.01%—while also improving the detection of small blood vessels more consistently. These findings demonstrate that the appropriate application of contrast enhancement plays a crucial role in improving the quality of medical image segmentation.

Abstract

Foot and Mouth Disease (FMD) is a highly contagious livestock disease that causes significant economic losses. Timely detection is essential to prevent rapid transmission. While deep learning has shown promise in image-based disease identification, the impact of integrating lightweight attention mechanisms, such as the Convolutional Block Attention Module (CBAM), into robust multi-scale backbones, such as InceptionV3, for FMD detection on small, imbalanced primary field datasets remains underexplored. This study contributes by providing a systematic evaluation of CBAM integration under varying data-splitting scenarios, highlighting the interaction between attention mechanisms and data distribution. This study evaluates the integration of CBAM into InceptionV3 for the classification of cattle lesion images. It compares its performance with the baseline InceptionV3 model across three train-validation-test splits (70:20:10, 80:10:10, and 70:15:15). The dataset comprises 798 primary images (514 FMD-positive and 284 healthy), indicating a limited size with moderate class imbalance. Images were resized to 299 × 299 pixels and normalized to [-1, 1], with augmentation applied only to the training set. The InceptionV3-CBAM model achieved the best performance under the 70:15:15 split, with 96.69% accuracy, 96.25% precision, 98.72% recall, and 97.48% F1-score. These findings suggest that CBAM can enhance lesion-focused feature representation and detection sensitivity. However, performance gains were inconsistent across splits and appear influenced by both architectural changes and dataset characteristics. The model demonstrates potential for early FMD screening in resource-limited settings, but further validation on larger, more diverse datasets is essential to confirm robustness and generalizability

Abstract

In Indonesia, rice is a vital component of food security, but persistent leaf diseases threaten productivity. Currently, field identification relies on labor-intensive, human-error-prone manual observation. To address this, we developed an accurate and interpretable classification model integrating the MobileNetV3-Large with Gradient-weighted Class Activation Mapping (Grad-CAM). The model obtained 98.82% validation accuracy after being trained via transfer learning on a public dataset with four classes: healthy, bacterial leaf blight, brown spot, and blast. The dataset was partitioned using a 90:10 data split (5,018 training and 612 validation samples). The model achieved a validation accuracy of 98.82% alongside robust multi-metric performance, obtaining a weighted average precision of 99.00%, a recall of 98.80%, Micro AUC and Macro AUC both reached 0.9977, and an F1-score of 98.90%. Furthermore, Grad-CAM analysis confirmed that the model's predictions are interpretable. The resulting heatmaps consistently concentrated on leaf regions exhibiting disease symptoms, demonstrating that the network learned visually meaningful features despite minor background activations. These findings validate that combining MobileNetV3-Large with Grad-CAM yields an effective, transparent classification system, offering strong potential for robust, user-verifiable rice disease diagnosis in agricultural deployments.
