Environmental cleanliness problems in Neighborhood Unit 10 Community Unit 5, Pematang Gubernur Subdistrict, Muara Bangkahulu District, Bengkulu City, are influenced by limited waste disposal and segregation facilities as well as the absence of established habits in sorting waste according to its type. This condition reduces the comfort of shared spaces and increases the potential for waste accumulation, particularly in areas frequently used for social and religious activities. This community service activity aimed to provide waste segregation facilities and encourage behavioral change by promoting waste sorting at the source. The implementation method included environmental observation, discussions with local authorities and mosque administrators, design and construction of organic and non-organic waste bins, placement of facilities at strategic locations in Al Fathonah Mosque, and brief socialization regarding proper waste disposal practices. Evaluation was conducted through observation of initial utilization, feedback from mosque users, and coordination with local administrators regarding maintenance. The results showed the availability of separated waste bins that were actively used by worshippers and nearby residents, improved orderliness in waste disposal, and the early formation of waste sorting habits. Program sustainability was supported through routine coordination between mosque administrators and neighborhood leaders to ensure regular cleaning, condition monitoring, and consistent implementation of usage guidelines so that the benefits could be maintained in the long term.
