Garbage problems occur due to the imbalance between waste production in the community and the government’s ability to manage the waste. The old patern of collect–transport–dispose will give more burden to the system because of the increasing needs of infrastructures. This study aims to develop the integrated waste management model of Medan City with dynamic system approach. To be able to apply the new waste management model, the active roles of community are needed; therefore, it is necessary to know how far the perception and participation of community in the waste management nowadays. Based on the Law No. 18 of 2008 that the waste management starts from the source level (community) that is by reducing, reusing and recycling. The result of the study showed that the community perception on the waste management was good enough, but the participation was still very low both direct and indirect participation. The implementation of waste bank scenario and independent composter per–neighborhood can decrease the waste production entering the landfill (TPA) up to 13.5% and decrease the need of waste truck from 394 units to 333 units. The total cost of waste processing also decrease in amount of 180,257,000,000 in 10 years.
