The increasing population of Indonesia has led to a rise in household waste generation. According to data from the Ministry of Environment and Forestry (KLHK), Indonesia produces approximately 21 million tons of waste annually, with 34.29% (7.2 million tons) being poorly managed, resulting in environmental pollution. The lack of public awareness, especially among children, in waste sorting exacerbates this issue. Research indicates that 56.3% of students have limited knowledge of waste types, and 37.5% have not yet implemented waste sorting at school or home. To address this problem, the author developed an educational waste-sorting game using Construct 2. This study employs the Multimedia Development Life Cycle (MDLC) method, which consists of six stages: concept, design, material collection, assembly, testing, and distribution. The test results show that the application achieved an average score of 78.57% among SD Muhammadiyah students, 80% in media testing, and 100% in material testing, with most respondents providing positive feedback. The application was successfully designed and tested, demonstrating that its features align with user needs. Hopefully, this educational game can be an innovative solution to raise children's awareness of the importance of waste sorting from an early age.
