| Trash is known as a problem that is difficult to solve, especially in big cities. Lack of discipline, understanding, and public awareness of cleanliness is caused by social factors namely the low level of education of the community and the consequences of lifestyle or habits (behavior) patterns of the population, for example throwing garbage in any place. The selection of waste temporary disposal sites (TPS) is one of the important things in the waste processing, which is to determine the total cost of transportation which improper allocation will cause increased cost. In this study, the existing disposal site in Semper Barat and Semper Timur villages totaled 16 locations. Government regulations state that a TPS can cover a radius of 1 km and with a minimum capacity of 400 households. Determine the optimum number of TPS using the Set Covering Problem model with the help of LINGO and AutoCAD software. Set Covering is a way to determine the lowest cost of placing a number of facilities where each demand node can be reached by at least one facility. Based on the results of calculations, the optimal number of TPS for the regions of Semper Barat and Semper Timur villages is 12 locations selected from a total of 16 TPS. |
