OPTIMASI RUTE PENGANGKUTAN SAMPAH DI KOTA LAMONGAN DENGAN MENGGUNAKAN METODE SAVING MATRIX

Abstract

The system and transport of waste is one of the most expensive elements of waste management   system   in   city.   According  to   Apaydin   (2007),   the   system   and transport   of   waste   requires   about   85%   of   the   total   waste   management   system. Meanwhile, according to Damanhuri (2010) transportation costs of waste is 50% - 60% of the total cost of waste management. Limitations of funds allocated by the Lamongan   District   Government   for   waste   management   is   another   problem   that adds to the complexity of waste problems, especially by means of waste transport. The   impact   is   waste   accumulation   in   some   areas.   This   research   is   conducted   to give recommendation of waste transportation route optimally using saving matrix method in the Lamongan city. Saving Matrix method is one of the methods used to determine the optimal route of waste transportation by minimizing the distance and travel time based on the transport load so that the shortest route and minimum transportation   cost   are   obtained.   This   research   resulted   14   routes   of   waste transportation   at   Lamongan   City   with   total   distance   120.24   km   with   total   time 180.33 minutes. Total cost monthly is Rp. 9.288.540, -. So from the use of saving matrix method can save costs Rp. 656.625- per month or Rp. 7.879.500 - per year.
