The results of this study are based on several informants saying that it is important to have this L2T2 program. Due to the blessings of this program, cleanliness in several disposal sites such as ditches and rivers has become cleaner. The conclusion of this study is the lack of public knowledge about this program, and the community does not want to pay a predetermined monthly rate and they do not want to damage the condition of their homes due to a control hole created.
