Waste is still a problem in major cities in Indonesia. The high production of waste is not proportional to the availability of the landfill (TPA). The land use plans for waste landfill by local governments have conflict potential between government and community when such infrastructure facilities are not desired by the community. Environmental conflicts/disputes can be resolved through mediation mechanisms. This research uses linear regression modeling system to see the correlation between the amount of waste volume generated with the availability of landfill (TPA) in Central Java Province. The results showed the greater the number of residents the greater the volume of waste generated. In contrast the number of available landfill (TPA) is not affected by the volume of waste because the regression coefficient is only 0.0256.
