Teenager’s obesity is public health issue that needs attention because of the increasing risk of other diseases such as diabetes. This study purposes to build a system that can predict the risk of teenager’s obesity. The data is in the form of a secondary dataset that has 17 features that include eating habits, physical activity, and others. Random Forest is used because of its ability to handle high-dimensional data and produce accurate classifications. This system is console-based, where users can add their lifestyle data and get results in the form of obesity predictions with low, medium, and high levels. The results of the model evaluation show very good results, which 90%  accurate and high consistency, recall, and f1-score values. This method shows stable and competitive performance compared to other algorithms such as Decision Tree and KNN. So the results are expected to be used as a learning and prevention tool to detect the risk of obesity in adolescents early on.

Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis. Indonesia is one of the countries with the highest number of TB cases in the world. The key to successful TB treatment is treatment adherence. One factor that influences treatment adherence is stigma, which can result in incomplete treatment. This study aimed to determine the relationship between stigma and adherence to pulmonary TB treatment in the city of Lhokseumawe. The research method used was descriptive correlational with a cross-sectional approach. The sampling method was quota sampling with a sample size of 83 pulmonary TB patients. Data were filled in by filling out the Internalized Stigma of Mental Illness (ISMI) scale and Morisky Medication Adherence Scale (MMAS-8) questionnaires, and the data were analyzed using the Spearman correlation test (p = 0.05). The results of the bivariate test of age, gender, last education, occupation, and PMO did not have a relationship with adherence to pulmonary TB treatment, with a p value> 0.05. However, the duration of treatment had a relationship with the level of adherence to pulmonary TB treatment, with a p-value = 0.008. The study's results also showed that stigma and treatment compliance did not have a significant relationship, with p-value = 0.197. It was concluded that there was no relationship between stigma and compliance with pulmonary TB treatment.

Diabetes mellitus, especially type 2, is a growing epidemic with almost 90% of cases reported worldwide. Antioxidants are compounds that are in lower concentrations compared to the concentration of oxidizable compounds, can significantly prevent or inhibit the oxidation of the substrate. The formation of more stable oxidant compounds through intramolecular hydrogen bonds in the further oxidation process. Data collection was carried out using Google Scholar, Science Direct and PubMed databases. The literature sources used were in the form of research results that had been published in 2011-2021 in national and international journals. Providing antioxidants is an effort to inhibit the production of intracellular free radicals or increase the ability of defense enzymes against free radicals in order to prevent the emergence of oxidative stress and diabetes-related blood vessel complications. Various supplements containing antioxidants and/or factors that can increase the production of nitric oxide (NO) have the potential to improve endothelial dysfunction and mitochondrial function in cells, as well as reduce the activity of the NAD(P)H oxidase enzyme.
