Abstract

This study aims to detect mushroom diseases based on digital images using the Deep Learning Convolutional Neural Network (CNN) method. Fungal diseases are often the main cause of decreased quality and yield, so a fast and accurate detection method is needed. The dataset used consists of images of healthy mushrooms and diseased mushrooms obtained through direct image capture at the cultivation location. The research stages include image preprocessing, CNN model training, and performance evaluation using accuracy, precision, recall, and F1-score metrics. The results show that the CNN model is able to detect mushroom diseases with a high level of accuracy, so this method has the potential to be used as a decision support system in mushroom cultivation.

Abstract

The rapid growth of mobile-based ride-hailing services in Indonesia has significantly increased the use of digital platforms such as Gojek. This growth has generated a large volume of user reviews on the Google Play Store, reflecting user experiences, perceptions, and satisfaction levels. However, manual analysis of these reviews is inefficient due to their volume and subjective nature. Therefore, this study aims to model sentiment patterns in Indonesian Gojek user reviews using a machine learning approach. This research applies the Support Vector Machine (SVM) algorithm combined with Term Frequency–Inverse Document Frequency (TF-IDF) for feature extraction. The dataset consists of 5,000 Indonesian-language user reviews collected from the Google Play Store. Text preprocessing includes case folding, cleaning, tokenizing, stopword removal, and stemming. Sentiment labeling is performed automatically using a lexicon-based approach, classifying the data into positive, negative, and neutral categories. The results indicate that neutral sentiment dominates the dataset (60.26%), followed by positive (31.34%) and negative (8.40%) sentiments. The SVM model achieves an accuracy of 72.58%. The neutral class shows the highest recall (99.17%), while the positive class achieves the highest precision (99.65%). These findings indicate that TF-IDF and SVM are effective for modeling sentiment patterns, although challenges remain in handling ambiguous expressions, such as sarcasm or mixed sentiments, which can lead to misclassification.

Abstract

This study examines the sensitivity of hierarchical clustering results to the choice of distance metrics using Z-score standardized data from the World Happiness Report. Socio-economic datasets often contain variables with different scales, which can bias distance-based clustering methods if not properly addressed. Therefore, Z-score normalization was applied to ensure each variable contributes equally to the distance computation. The analysis focuses on six socio-economic indicators, namely gross domestic product (GDP), social support, healthy life expectancy, freedom to make life choices, generosity, and perceptions of corruption. Hierarchical clustering was performed using a fixed average linkage method to control the cluster-merging strategy, while three distance metrics Euclidean, Manhattan, and Cosine were compared to evaluate their influence on clustering outcomes. The results demonstrate that the selection of distance metrics affects dendrogram structure, cluster membership, and the relative proximity among countries. Differences across distance metrics were further reflected in internal cluster evaluation using the silhouette coefficient, indicating varying levels of cluster compactness and separation. These findings highlight that, even after proper normalization, distance metric selection plays a critical role in shaping hierarchical clustering results and their interpretation in socio-economic analyses. Overall, the study underscores the importance of methodological consistency and careful metric selection when grouping countries based on multidimensional happiness-related indicators.

Abstract

This study examines the robustness of the K-Medoids algorithm to the presence of outliers in management data derived from Airbnb property listings, focusing on price and review rating attributes as key indicators in market segmentation and managerial decision-making. The increasing use of data from digital platforms is often accompanied by the emergence of extreme values that have the potential to disrupt the cluster structure and reduce the reliability of the analysis results. Therefore, a clustering method is needed that is able to maintain the stability and consistency of results even though the data contains outliers. This study uses a quantitative and experimental approach based on secondary data, where the implementation of the K-Medoids algorithm and visualization of clustering results are carried out using Python programming, while manual calculations based on Excel spreadsheets are used as a means of conceptual validation of the medoid selection process and distance measurement. The analysis is carried out by comparing the cluster results before and after the presence of outliers using the Manhattan distance metric and evaluating the total cost function at each iteration. The results show that although extreme values in the price attribute cause a wider spread in the data, the cluster structure and medoid positions remain relatively stable. The resulting clusters also retain clear managerial significance, grouping properties into economy, regular, and premium segments, thus remaining relevant to support pricing strategies, service differentiation, and reputation management.

Abstract

Decision tree models are widely applied in educational data analysis due to their simplicity and interpretability. However, these models exhibit high sensitivity to variations in training data, where minor sampling changes can result in substantially different tree structures, potentially reducing model reliability and consistency. This study aims to empirically investigate the structural robustness of decision trees under variations in educational data sampling and to evaluate strategies for improving model stability. An experimental framework is implemented using several educational datasets processed through random subsampling, bootstrap resampling, and k-fold cross-validation. Structural robustness is quantitatively assessed using tree edit distance, node similarity ratio, and tree depth variability. The results indicate that small sampling perturbations can cause significant structural divergence, particularly in datasets characterized by high noise levels and feature correlations. Nevertheless, pruning techniques and ensemble-based stabilization methods effectively enhance structural consistency and reduce model variance. These findings highlight the importance of robustness evaluation in educational data mining and provide empirical insights for developing reliable, stable, and interpretable decision-support systems in educational environments.
