Collaboration program between the Faculty of Science and Technology, Medan Area University and PT. Nusantara Siana Eko Solusi (PT. NSES) and Malaysia, which involved consultants from Singapore from 20 to 22 February 2020. In this case, the collaboration is engaged in waste management in several Regencies / Cities in Indonesia. The first city visited was Dumai City, because Dumai was one of the Regencies / Cities that had problems with waste management. The rubbish there is treated lenfil (planted in the ground) and then given a pipe to release gas, this model is very dangerous, can cause fires and blasting large enough that can cause poisoning to the surrounding community.
