From the results of this research, it can be concluded that; Sapaia's PILSADAR program is currently not running effectively because this program has only been implemented in the Sembalun area and is only implemented twice a week. The author says that there needs to be more intensive evaluation and coordination as well as follow-up to ensure that PILSADAR is implemented according to expectations and achieves appropriate results. Overall, this could have a positive impact on the entire Tanjung Karang Village; Furthermore, the obstacles faced by the Government in implementing the Segregate Waste from Home (Pilsadar) Program in Tanjung Karang Subdistrict are the limited budget in the subdistrict which is the main obstacle in implementing the pilsadar program.

This can hinder the distribution of rubbish sacks or transport of rubbish from home to waste management centers.
