This study aims to explore gross motor developmental delays in 6-year-old children as an early indication of possible Tourette syndrome. Tourette syndrome is a neuropsychiatric disorder characterized by the emergence of spontaneous movements and sounds (tics) that are not realized and can interfere with the child's daily activities. In this study, a qualitative approach was used with a case study method on a boy in Malang City who showed symptoms of motor and vocal tics. Data collection was carried out through observation, in-depth interviews with teachers and parents, and documentation of the child's activities in the home and school environment. The results of the observation showed that the child had difficulty maintaining balance and showed spontaneous movements such as shaking his head, blinking, and clearing his throat repeatedly. These symptoms do not always appear consistently and occur more often when the child is tired or mildly stressed. Data analysis showed that motor delays were not caused by muscle disorders, but by an imbalance in neurological regulation that affects movement coordination. The main risk factors come from daily habits such as excessive use of gadgets, lack of rest time, and unstable emotional responses. The treatment carried out involves a combination of medication from a neurologist and environmental support such as reducing stress triggers, regulating playtime, and an inclusive educational approach. This study emphasizes the importance of early detection, holistic intervention, and ongoing support from families and educators in dealing with children with Tourette syndrome symptoms so that motor delays do not develop into more serious disorders.

This study aims to analyze the impact of online gambling and drug abuse on the economy of the community in Beratkulon Village, Kemlagi District. The method used in this research involves socialization and discussions with local residents to gather data and information regarding the issues faced. The results indicate that online gambling and drug abuse not only lead to financial losses for individuals but also trigger family conflicts, accumulation of debt, and loss of community productivity. Furthermore, the lack of education about the dangers of drugs and weak supervision are contributing factors to the increasing cases of abuse. This research recommends the need for enhanced community awareness through more intensive educational and socialization programs, as well as strengthening the role of media in disseminating positive messages to prevent drug.

The set theory approach, which is often used in pure mathematics, can be applied to analyze relations between indigenous communities in Papua. This article maps cultural relations between three main indigenous communities Kamoro, Amungme, and Dani with a mathematical approach. Each community is represented as a collection of unique cultural elements, such as wood carving traditions (Kamoro), mountain beliefs (Amungme), and ancestral mummy traditions (Dani). This analysis involves the concepts of intersection, combination, and complementation to identify similarities, uniqueness, and potential conflicts and synergies between communities. This study found that although there is no direct cultural intersection, the combination of cultural elements shows significant richness. This approach provides a systematic tool for understanding relationships between communities, supporting cultural preservation, and creating social harmony.
