This study aims to determine the extent of the implementation of the Regional Regulation No. 12/2018 on Regional Levies in Gunung Mas Regency on Calibration/Recalibration Service Charges, and to find out the obstacles that occur in implementing these policies. This research is located in Kurun Subdistrict, Gunung Mas Regency. The data collection technique was carried out in three steps, namely: observation, interview, and documentation. The informants of this research consisted of: 1) Head of Consumer Protection and Metrology Division of the Industry and Trade Service of Gunung Mas Regency; 2) Head of Metrology Section; 3) Metrology Sector Staff; and 4) Traders who have received services and who will assess how the policies calibration/recalibration are applied. This study uses qualitative data analysis following the concept of Miles and Huberman's model with the theory of policy implementation according to Edward III. The results of the study show that the implementation of Regional Regulation Number 12 of 2018 concerning Retribution for Recalibration Services in Gunung Mas Regency is still not effective. This ineffectiveness occurs due to several obstacles, namely the absence of socialization from the Dinas regarding the SOP for implementing Recalibration services to the community. This also resulted in a lack of public knowledge about the policy, which hindered policy implementation. Limited funds are also an obstacle in the distribution of information to the public.
