Waste management is an essential aspect of fulfilling the community’s right to a clean and healthy environment. This study aims to analyze the implementation of Regional Regulation of Timor Tengah Selatan Regency Number 4 of 2018 on Waste Management in Kota Soe District and to identify factors that hinder its implementation. The research employs an empirical juridical method with a socio-legal approach. Data were collected through interviews, field observations, and literature studies. The respondents consisted of 26 individuals, including officials of the Environmental Agency, the Technical Implementation Unit for Sanitation and Parks, village officials, sanitation workers, and community members. Data were analyzed qualitatively using a descriptive juridical method. The findings indicate that waste management implementation has been carried out through planning, implementation, supervision, and accountability stages by the Environmental Agency with the support of the Technical Implementation Unit; however, it has not been fully effective. Internal obstacles include limited human resources, budget constraints, and inadequate facilities and infrastructure. Meanwhile, external obstacles mainly arise from the low level of community participation and awareness in waste segregation and management at the source. This study concludes that the effectiveness of waste management policies depends not only on the existence of regulations but also on the availability of adequate resources, budgetary support, effective institutional coordination, and active community involvement.
