The decision to open/close the facility and or change the existing facility's size is a solution due to the imbalance between the volume of demand (amount of waste) and the facility's capacity (temporary disposal site). In some locations, there are restrictions or restrictions on receiving waste sources from outside the area. The existing Environmental Service facility has several types with different capacity sizes. The possibility of opening the facility starts with screening the location of the location points that meet the requirements and the size of their possible capacity.  

Then modeling this set covering problem by considering the capacity, type of facility, and area using pure integer non-linear programming (PINLP).  The decision was obtained from 78 facilities that have been operating so far; only 27 facilities will be maintained, closing 51 facilities and opening three new ones. Of the 27 facilities that have been maintained, 17 have been resized. This decision will give a total facility capacity of 655 m3 / day, which is more significant than the initial conditions of only 565.29 m3 / day. The proposed decision is expected to cover the total amount of waste, namely 629.18 m3 / day.
