Abstract

The pervasive use of smartphones in daily life has led to significant benefits, but excessive use has caused alarming behavioral and health issues, particularly among adolescents. Addressing smartphone addiction requires early detection to enable timely interventions. This study investigates the application of machine learning, specifically Linear Discriminant Analysis (LDA) and Quadratic Discriminant Analysis (QDA), for the early prediction of smartphone addiction. The research used a dataset containing 394 instances categorized into "addicted" and "non-addicted" classes. Dataset is derived from questionnaire responses. After preprocessing steps, including feature selection and ordinal encoding, the data was split using 10-fold cross-validation to ensure robust evaluation. The models were assessed using metrics such as accuracy, precision, recall, and F-measure. Results indicate that LDA significantly outperforms QDA across all metrics, achieving an accuracy of 94.16%, a precision of 94.2%, a recall of 94.2%, and an F-measure of 94.2%. Additionally, the Receiver Operating Characteristic (ROC) curve analysis showed an Area Under the Curve (AUC) of 0.9875 for LDA, indicating its high reliability and stability in classifying smartphone addiction. QDA, while effective, has a slightly lower performance due to the linear separability of the dataset. This study concludes that LDA is a robust and effective method for early prediction of smartphone addiction, offering valuable insights for health monitoring systems. The findings provide a foundation for future applications of discriminant analysis in addressing behavioral health issues.

Abstract

Human health is an important thing to keep. Health has to be maintained with appropriate rest. Lack of rest has a bad impact on the body such as hormonal imbalances. One of the causes of lack of rest is insomnia. Insomnia is a phenomenon that describes someone's difficulty sleeping. Insomnia is often considered trivial, but chronic insomnia puts the sufferer at risk of serious illness physically and psychologically. Some people sometimes don't realize that they have insomnia because they feel like they have trouble sleeping. Therefore, early detection of insomnia is necessary to do. This study uses a machine learning approach to make predictions, namely the AdaBoost + grid search method. AdaBoost is used because of its reliability in making strong classifiers and grid search is applied to tuning parameters from AdaBoost. Parameters that are optimized are the n estimator and learning rate. Parameter tuning by grid search gives n – estimator = 76 and learning rate = 0.1. Some preprocess technique is done, there are normalization and ordinal encoding then data splitting based on the determined ratio. There are 80% for training data and 20% for testing data. On training data, the result is 98% percentage for each accuracy, precision, recall, and f1 score. This value is better than the comparison method, it is LogRegression that only reaches 97% value on each evaluation measure. The model implemented on test data and AdaBoost + grid search obtained 100% accuracy, precision, recall, and f1 score. However, LogRegression only gives 98% result. This study proved that AdaBoost with grid search is sustainable to do early prediction of insomnia.

Abstract

Mental health disorders are often difficult to detect and diagnose, causing misdiagnoses which lead to inappropriate treatment and have a negative impact on the sufferer's quality of life. This research aims to develop an accurate and efficient model for identifying mental health disorders by utilizing the Random Forest method and Cross Validation techniques. Random Forest was chosen because of its ability to improve prediction accuracy and training speed. Cross Validation is used to train and test models with various combinations of data, and reduces the risk of Overfitting. The dataset consists of 120 data with 18 behavioral attributes and diagnoses, with four target classes: Bipolar Type-1, Bipolar Type-2, Depression, and Normal. Four Cross Validation experimental scenarios were tested: k=5 and k=10, and k=5 and k=10 with Stratified to reduce data bias. Experimental results show that k=10 stratified cross-validation produces the highest accuracy (87.5%), with precision, recall, and F1-score also reaching 87.5%. The Stratified technique is proven to improve the balance of class distribution and reduce the risk of Overfitting. These findings confirm that Random Forest with k=10 Stratified Cross-Validation is the optimal approach for diagnosing mental health disorders. The implications of this research include the potential for applying models in AI-based systems to assist medical personnel in more accurate and efficient early diagnosis.

Abstract

Stroke is a leading cause of disability and mortality worldwide, necessitating immediate and accurate first aid to mitigate severe outcomes. In Indonesia, limited public knowledge about stroke management, particularly among high school students, underscores the urgent need for targeted educational interventions. This study aims to evaluate students’ understanding of stroke first aid and identify optimal methods for clustering educational data using Agglomerative Hierarchical Clustering (AHC). A validated questionnaire was distributed to 112 high school students, focusing on their knowledge of stroke symptoms, risk factors, and first-aid practices. Data preprocessing ensured quality and consistency before applying AHC with three linkage methods: Single Linkage, Complete Linkage, and Ward’s method. The results were evaluated using Davies-Bouldin Index and Silhouette Coefficient to determine the most effective clustering approach. Ward’s method outperformed other linkage methods, achieving superior cluster compactness and separation. Four clusters were identified, representing varying levels of knowledge, from basic understanding to high awareness of stroke and seizure management. These findings provide a foundation for designing tailored educational programs, addressing specific knowledge gaps, and enhancing firstaid preparedness. This study demonstrates the utility of machine learning in educational research and contributes to improving public health education. Future research should expand on these findings by incorporating diverse datasets and alternative clustering algorithms.

Abstract

Self-esteem plays a crucial role in students' psychological well-being, influencing their academic performance and personal development. Despite its importance, self-esteem is challenging to measure due to its abstract and subjective nature. This study aims to develop a predictive model to classify students’ self-esteem levels as high or low using machine learning and tabular data obtained through questionnaires. A dataset comprising 47 student responses, with 19 features consisting of social, emotional, demographic aspects, were analyzed. Five machine learning models were evaluated: Naïve Bayes, Decision Tree, Random Forest, Logistic Regression, and Support Vector Machine (SVM). To address the class imbalance in the dataset, the study applied SMOTE for data balancing and min-max normalization for feature standardization. Model performance was assessed using accuracy and F1-score. The results reveal that SVM, particularly with an RBF kernel, outperformed other models across all scenarios. On raw data, SVM achieved 66% accuracy and an F1-score of 57.3%. After applying SMOTE, the performance improved to 80% accuracy and a 79.9% F1-score. Further enhancement with normalization resulted in the best performance, with SVM achieving 83.33% accuracy and an F1-score of 83.3%. These results demonstrate how well preprocessing methods work to enhance machine learning models for datasets that are unbalanced. The proposed SVM-based model offers promising applications in educational and psychological settings, enabling early interventions to support students’ mental health.

Abstract

Jamur memiliki peran penting dalam keanekaragaman hayati, namun beberapa spesies seperti Agaricus xanthodermus dan Amanita muscaria bersifat beracun dan dapat menyebabkan risiko kesehatan serius jika dikonsumsi. Identifikasi jamur beracun secara akurat menjadi tantangan karena kemiripan morfologinya dengan spesies non-beracun. Penelitian ini mengusulkan model klasifikasi jamur beracun menggunakan metode transfer learning dengan arsitektur MobileNetV2, yang dikenal efisien dalam memproses data visual. Dataset terdiri dari 632 gambar, masing-masing 304 gambar untuk Agaricus xanthodermus dan 328 gambar untuk Amanita muscaria, yang diperoleh dari platform Kaggle dan dibagi menjadi 80% data latih dan 20% data validasi. Augmentasi data seperti rotation, shift, flipping, dan rescaling diterapkan untuk meningkatkan generalisasi model. Eksperimen dilakukan dengan menguji pengaruh jumlah epoch terhadap performa model, menggunakan rentang 10 hingga 100 epoch dengan interval 10. Hasil menunjukkan bahwa akurasi model meningkat seiring bertambahnya jumlah epoch, dengan performa optimal pada epoch ke-60. Pada epoch ini, akurasi validasi mencapai 99.21% dengan nilai loss validasi terendah sebesar 0,0447, menunjukkan bahwa model mampu mengklasifikasikan kedua spesies jamur secara akurat dan efisien. Selain itu, tren akurasi dan loss pada data pelatihan menunjukkan bahwa model mampu belajar secara stabil dan tidak mengalami overfitting, bahkan ketika menggunakan dataset yang relatif kecil. Penelitian ini berkontribusi pada pengembangan metode klasifikasi jamur beracun yang lebih akurat dan efisien, yang memiliki implikasi penting dalam kesehatan masyarakat dan konservasi keanekaragaman hayati.
