This research delineates the worrisome phenomenon of suicidal ideation among adolescents, particularly students, which is on the rise. This issue poses serious challenges to mental well-being and public health. The objective of this study is to investigate suicidal ideation among adolescents, focusing on the impact of insufficient social support as a contributing factor. A total of 101 respondents aged 18-24 participated in the study, utilizing qualitative descriptive methods and questionnaires as data collection instruments. The results indicate that a significant portion of respondents experiences suicidal ideation, with a high belief in the role of family support in reducing the risk of such thoughts. The complexity of social relationships, including a lack of support from friends and the repercussions of losing a partner, also plays a crucial role in suicidal ideation among adolescents. This research provides a foundation for an in-depth understanding of the factors influencing suicidal ideation and encourages more effective prevention efforts in the future. It contributes significantly to prevention by informing strategies with a specific emphasis on enhancing social support to reduce the prevalence of suicidal ideation and improve the overall mental well-being of adolescents.
