Abstract

The aim of the proposed research is to compare and test the accuracy of data mining classification algorithms. Comparing algorithms that depend on different parameters of a given data set. There are learning and classification algorithms that are used to analyze, study and classify the available data. However, the problem is finding the best algorithm and the desired results with the highest level of accuracy in predicting future values ​​or events from a data set. Where the classification models used are the C4.5 and Naïve Bayes algorithms. Testing and validation using k-fold Cross Validation as well as evaluating the performance of the prediction model using the ROC-AUC graph with graphic visualization. The data used as samples were taken from ATM machine problem data with a total of approximately 250 samples. Testing was carried out with the help of the Rapidminer tool with operators and parameters used in creating models of the algorithms being compared. The tests that have been carried out prove that the C4.5 algorithm has the best performance with an average accuracy value of 96.00%, a recall value of 97.78% and a precision value of 92.14%, while the naïve Bayes algorithm produces an accuracy value of 83. 00%, the recall value is 76.40% and the precision value is 84.82%. Apart from that, evaluation and validation in this test is also seen based on the ROC curve called AUC (Area Under the ROC Curve) where for the C4.5 algorithm the value is 0.931 while naïve Bayes is 0.894 so the C4.5 algorithm is categorized as Very Good Classification because it has a value between 0.90-1.00. These results show that the C4.5 algorithm is proven to be a potentially effective and efficient classification algorithm.

Abstract

Hypertension is a major risk factor for cardiovascular disease, posing significant public health challenges globally. The prevalence of hypertension with uncontrolled blood pressure and its increasing number is not only caused by individual negligence but can be caused by community ignorance as a result of a lack of information on a disease. Measures to control and prevent hypertension in the community can be carried out including hypertension self-management education, introduction of antihypertensive plants, and training in making health supplements from herbs. To improve the degree of public health and knowledge of the community in the area of West Martapura Subdistrict, counseling, and training were conducted with the PKK mobilizing team of West Martapura Subdistrict using visual (electronic) media, leaflets in the form of education and demonstrations of making health supplements (fermented garlic). In this activity, the average post-test results of knowledge about self-management of hypertension prevention and control were 90.5, the average knowledge of herbal plants that have the potential as antihypertensives was 89.0 and the average post-test value of knowledge and skills in making health supplements from herbal plants in the form of fermented garlic was 84.5.

Abstract

Stunting remains a major public health challenge in Indonesia, with national prevalence among children under five reaching 21.6% in 2022, according to the Ministry of Health. This condition, defined by the World Health Organization as a height-for-age less than -2 SD, is associated with long-term consequences including impaired cognitive development, reduced educational attainment, and diminished economic productivity. Addressing stunting is therefore critical to achieving Sustainable Development Goals (SDGs) related to hunger, health, and education. Despite multiple national initiatives, early identification of stunting risk is still limited by reliance on conventional, reactive surveillance methods. Recent advances in machine learning (ML) provide promising alternatives for proactive stunting prediction, with several studies reporting high predictive accuracy using ensemble methods, hybrid frameworks, and geographically weighted models. Building upon this evidence, the present study develops and evaluates ML models for stunting risk prediction using a large dataset of 10,000 records from North Sumatra, Indonesia. The dataset included three predictor variables—age, height, and weight—and a target variable, nutritional status (Normal, Stunted, Severely Stunted, Tall). Four algorithms were compared: K-Nearest Neighbors (KNN), Naïve Bayes, Decision Tree, and Random Forest. Performance was assessed using accuracy, precision, recall, F1-score, and ROC area, with 10-fold cross-validation ensuring robust estimation. Results demonstrated that Decision Tree (88.6% accuracy) and Random Forest (88.3% accuracy) outperformed KNN (84.7%) and Naïve Bayes (72%). ROC areas further confirmed the superiority of ensemble-based approaches, particularly Random Forest (0.979). Statistical significance was tested using McNemar’s test, revealing that Decision Tree and Random Forest achieved comparable performance (p = 0.651), both significantly outperforming KNN and Naïve Bayes (p < 0.05). This study contributes a context-specific evaluation of ML methods for stunting prediction in North Sumatra, emphasizing not only predictive accuracy but also interpretability to support health policy and program implementation. By bridging data-driven insights with actionable decision support, the proposed framework advances progress toward SDG-aligned strategies and provides a foundation for more targeted and preventive interventions in child nutrition and growth monitoring.

Abstract

ABSTRACT Wastewater management is one of the most important environmental issues, especially in sectors that generate large amounts of liquid waste, such as restaurants and other public facilities. With the increasing awareness of the importance of environmental sustainability, research on wastewater management continues to grow, focusing on treatment technologies, management policies, as well as the behavior of waste managers themselves. The purpose of this study is to analyze publication trends and bibliometric mapping related to wastewater management, as well as identify factors that influence the behavior of waste managers, particularly in the context of the restaurant and public facilities sector. The method used in this research is a bibliometric approach, using the Publish or Perish application to collect relevant articles from various scientific publications between 2014 and 2024, which were then analyzed with VOSviewer to produce network visualizations, overlays, and densities to map trends, relationships between keywords, and emerging clusters. The results of the analysis show that research related to wastewater management focuses mostly on technical aspects and treatment technologies, but also increasingly pays attention to the influence of waste management behavior and social and cultural factors that influence management decisions. Some of the research gaps found are the need to dig deeper into the influence of social, cultural factors, as well as education policies in influencing waste management. The conclusion of this study is that wastewater management requires a holistic approach, incorporating technology, human behavior, and more effective policies. Further research focusing on the factors that influence the behavior of waste managers will be crucial to formulate more effective and sustainable policies in waste management in the future. Keywords: Wastewater Management, Manager Behavior, Treatment Technology, Environmental Policy, Bibliometric Study  ABSTRAK Pengelolaan air limbah merupakan salah satu isu lingkungan yang sangat penting, terutama di sektor-sektor yang menghasilkan limbah cair dalam jumlah besar, seperti restoran dan fasilitas umum lainnya.
