Equipment plan are separated bin (40 liter and 110 liter), collection vehicles (820 liter), transfer station with 3R and non 3R, collection vehicles with hauled container (armroll  6 m3) and stationery container (pick up 2,5 m3).  Total cost management and retribution are  Rp.. 7,241,744,260.50 and Rp.  5.500-262.500.
