This study is a comparative analysis that compares five Indonesian folklores that possess a theme of a love story between a mere human being and a fairy. The folklores are Mamanua Lumalundung, Jaka Tarub, Lengajan, Salambous, and Rajapala. This study focuses on finding the similarities and differences among these five. By implementing Robert Stanton’s Structuralism theory in analyzing the data, it is found that they have similarities and differences in the characters or characterizations, plot, setting, and point of view. The similarity among the characters lies on the existence of a regular man and a fairy while the differences lie in their attitude, power, and life priorities. The similarity that can be found in the plot is the love story between a regular man and a fairy while the differences focus on the problems that are described in each folklore and how they handle the situation. For the setting, the similarity is the time setting which is ancient time while the differences are only the description of lakes, forests, and kingdoms. Lastly, the similarity of the point of view is being delivered by the third singular person while only Lengajan and Salambous use the first singular person in the dialogue.

Breast cancer is the most prevalent cancer among women worldwide, requiring early and accurate diagnosis to reduce mortality. This study proposes a hybrid classification pipeline that integrates Hybrid Statistical Feature Selection (HSFS) with unsupervised LSTM-guided feature extraction for breast cancer detection using the Wisconsin Diagnostic Breast Cancer (WDBC) dataset. Initially, 20 features were selected using HSFS based on Mutual Information, Chi-square, and Pearson Correlation. To address class imbalance, the training set was balanced using the Synthetic Minority Over-sampling Technique (SMOTE). Subsequently, an LSTM encoder extracted non-linear latent features from the selected features. A fusion strategy was applied by concatenating the statistical and latent features, followed by re-selection of the top 30 features. The final classification was performed using a Support Vector Machine (SVM) with RBF kernel and evaluated using 5-fold cross-validation and a held-out test set. Experimental results showed that the proposed method achieved an average training accuracy of 98.13%, F1-score of 98.13%, and AUC-ROC of 99.55%. On the held-out test set, the model reached an accuracy of 99.30%, precision of 100%, and F1-score of 99.05%, with an AUC-ROC of 0.9973. The proposed pipeline demonstrates improved generalization and interpretability compared to existing methods such as LightGBM-PSO, DHH-GRU, and ensemble deep networks. These results highlight the effectiveness of combining statistical selection and LSTM-based latent feature encoding in a balanced classification framework.
