The consumption of snacks sold outside of school environments contains a lot of sugar, such as artificial sweeteners. Environmental and social factors in schools, like unsupervised off-campus cafeterias, can influence children's food consumption patterns and oral health habits. This study aims to analyze the relationship between snack consumption and dental caries in school children. The research method used is correlation with a cross-sectional approach. A total sampling technique is applied to 80 respondents. Based on the research results, snack consumption is found to be 86.3% in the sufficient category, while 73.8% of respondents are categorized with dental caries. The Spearman rank correlation test resulted in p-value of 0.168 (p > 0.05), indicating that there is no significant relationship between snack consumption and dental caries among third and fourth-grade students. This study suggests that good oral hygiene and promoting healthy snacks should be targeted for preventing dental caries in children.

The policy of ownership of the right to the flats is an important aspect in the arrangement of vertical housing in Indonesia, especially in dense urban areas such as Kampung Utama Batam City. The background of this research focuses on the complexity of ownership dualism between individual property rights over units and collective rights to common parts, common objects, and common land. Conflicts of interest and management problems often arise, hindering the optimal implementation of policies. The purpose of this study is to analyze the implementation of government policies on ownership of rights to apartment units in Kampung Utama Batam City, identify existing obstacles, and provide recommendations for improvement. The research method used is a normative juridical approach with case studies. Data was collected through analysis of legal documents, interviews with stakeholders, and field observations. The analysis was carried out using positive legal theory from John Austin to understand the existing legal framework, legal system theory from Lawrence M. Friedman to evaluate the interaction between legal structure, substance, and culture, and legal certainty theory from Sudikno Mertokusumo to assess the clarity and predictability of applicable laws. The results of the study show that although the policy has been well drafted in Law No. 20 of 2011 concerning Flats, its implementation in the field still faces various obstacles. Dualism of ownership, unclear certificate status, complex administrative procedures, and lack of legal socialization are some of the main problems found. Strengthening the role of the Flats Owners and Occupants Association (P3SRS), the use of digital technology for administrative procedures, and increased supervision and law enforcement were identified as solutions to overcome these obstacles. The suggestions provided include increased coordination between related agencies, active community participation in the management of flats, and simplification of administrative procedures by the government. More effective implementation is expected to provide better legal certainty and create a harmonious residential environment in Kampung Utama Batam City.
