Elopement often arranged by parents, demonstrating bravery and maintaining family relationships. However, endogamous marriages in Merariq families can lead to health issues and genetic disorders. Among them, 75% of participants were admitted to endogamous marriages among relatives, and some parents forbid their children from marrying relatives due to guilt. Merariq marriages are decreasing due to the rupture of family ties. Elopement is a traditional rational action, low-risk, and based on customs and traditions. However, the community is unaware of the health risks and lacks prior socialization.

The existence of child exploitation and child labor will add to labor problems in Indonesia. The term "child labor" refers to people who employ children. The term "child labor" can be associated with the use of children's labor with low compensation or considerations regarding their personality development, safety, health, and future prospects. Most child workers do not have time to play or go to school like other children. Underage people work as hard as adults, both in formal and informal jobs. To save child labor in the future, a holistic and comprehensive solution model is needed. One method that can be used is a client-centered case management approach (centered on the client or child worker).
