This research investigates the factors contributing to low understanding of environmental degradation among sixth-grade students at SDN 12 Padang Koto Gadang. The study aims to identify internal and external factors affecting students' comprehension of environmental issues within the IPAS (Natural and Social Sciences) curriculum. Using a qualitative descriptive approach, data were collected through in-depth interviews with the class teacher, classroom observations, and document analysis of lesson plans and student assessment records. The findings reveal that internal factors include low learning motivation, where students perceive environmental materials as mere memorization tasks, and a significant mismatch between students' kinesthetic-visual learning styles (78%) and the predominantly auditory-lecture teaching methods. External factors encompass conventional teaching approaches dominating 85% of classroom time, limited technological infrastructure, and insufficient interactive learning resources. A paradoxical finding shows that while 70% of students claim environmental concern, only 23% consistently practice eco-friendly behaviors, indicating a substantial gap between cognitive knowledge and behavioral application. The study recommends implementing a hybrid learning model combining Problem-Based Learning with local contexts, utilizing simple nature-based media, and establishing strategic community partnerships. These findings contribute to developing more adaptive and contextual teaching methods aligned with Merdeka Curriculum principles for elementary environmental education.

Oil palm is a key commodity supporting Indonesia’s economy through exports and employment. The industry’s success depends heavily on the selection of superior seedlings, which determine productivity, crop quality, and resistance to pests and diseases. Manual selection, however, often leads to subjectivity and inconsistency due to limited human resources and genetic variation. To address this, the study applies the Naïve Bayes algorithm for classifying oil palm seedlings based on seven variables: height, stem diameter, number of leaves, leaf color, disease resistance, root growth, and fruit yield. Using an explanatory quantitative method, the study follows seven stages: identifying problems, literature review, collecting 1,000 data entries from PT Intitama Berlian Perkebunan, data pre-processing, system modeling (UML), algorithm implementation, and evaluation using a confusion matrix and black box testing. Data was split into 80% training and 20% testing. The Naïve Bayes-based classification achieved 95% accuracy and perfect recall (1.00) for the superior seedling class. However, its performance on the minority class (non-superior seedlings) was weaker due to dataset imbalance. Black box testing verified all system functions worked correctly, enabling effective and efficient use by administrators. The study concludes that Naïve Bayes improves objectivity, efficiency, and accuracy in seedling selection. Nonetheless, attention is needed on data balancing and optimization to maintain consistent performance across classes. This system shows strong potential as a decision-support tool in plantations and promotes digital transformation in agricultural processes.

This can be seen from (1) the rarity of students asking or responding to questions (2) students rarely communicate difficulties to teachers (3) students are also often late in submitting assignments. With these problems, researchers tried to apply the project based learning model with a constructivist approach analysis implemented at SMA Negeri 1 Majene. The subjects of this study were 38 grade X MIPA students of PAI subjects and one of the PAI subject teachers. The method used is descriptive qualitative, data collection techniques are observation, interviews and documentation. Data analysis techniques by means of data collection, data reduction, data presentation and drawing conclusions. The results of this study students have been faced with a problem and have the ability to analyze complex problems, investigate, evaluate, viewpoints and draw conclusions based on evidence and reasoning coupled with the spirit of student collaboration is very compact in each group, where a collaboration is a process of achieving a goal that is done together helping each other, and the most supportive thing in the learning process activities is the extrinsic factor of students which is the stimulation from outside, namely the people around them. In the application of constructivism in learning, it is expected that students are more active and teachers as facilitators become more innovative.

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.
