ing lifestyle patterns and obesity-related factors: K-Means, Agglomerative Clustering, and Gaussian Mixture Model (GMM). The data used in this study is sourced from the Food Nutrition dataset, which includes variables such as dietary habits, physical activity, and socio-economic status. The three clustering methods were assessed using evaluation metrics such as Silhouette Score, Davies-Bouldin Index (DBI), and Calinski-Harabasz Index (CHI). The findings revealed that K-Means exhibited the best performance in terms of cluster separation with a Silhouette Score of 0.5559, while GMM showed better flexibility in handling more complex data. Although Agglomerative Clustering produced acceptable results, it had a higher overlap between clusters compared to the other methods. This study offers valuable insights into selecting the most appropriate clustering technique based on the data characteristics.

rveyed regarding the handling of the Covid-19 pandemic. This research is an attempt to critique the Lowy Institute's assessment. The COPRAS-AHP hybrid method was used. The AHP method, especially in the pairwise comparison section, is used as a method to determine the validity of the criterion weights. Five criteria were used in determining the ranking of the handling of the Covid-19 pandemic in countries in the Southeast Asian region. Each criterion is given a weight that is determined subjectively but by considering the level of importance of each criterion. The weighting of the criteria by using pairwise comparison resulted in: test per population, positive per test, vaccine per population, recovered per positive, deaths per positive. This study produces conclusions that are not much different from the Lowy Institute release. Indonesia is one of the countries where the handling of the Covid-19 pandemic is at a low level, Indonesia is ranked 10th out of 11 countries in the Southeast Asia region, with a utility value 16.29%.
