Developing Suicide Risk Idea Identification for Teenager (SERIINA) Mobile Apps Prototype using Extended Rapid Application Development

Suicide death is the number 15 cause of death in the world. Suicide cases go undetected because the perpetrator shows no signs beforehand. Therefore, it is necessary to identify the risk of suicide in adolescents early, accessed quickly, maintains user privacy, and understand user needs. Using the Risk Factors of Suicidal Ideation (RFSI) questionnaire, it hoped to detect early suicide incidents in adolescents. This research proposed a Suicide Risk Idea Identification for Teenager (SERIINA), a mobile application developed using the Extended Rapid Application Development (ERAD) method. The ERAD method combines the concept of design sprint and RAD in the system development cycle. Based on the research results, SERIINA mobile apps development is completed in 19 days. The functional testing using Black-Box testing shows that the application works well and compatible with the five main scenarios. The results of interface design testing using heuristic evaluation indicate that the application has been well designed, with a usability value of 2.34 or about 72-85% according to design rules.
