This research on Street Vendors (PKL) aims to explain the policies of the Mataram City Government in structuring street vendors while at the same time identifying whether the arrangement of street vendors can contribute to Mataram City's Original Regional Income (PAD). This type of research is a descriptive quantitative evaluative research that uses field data as primary data through a regulatory approach and the legal basis in force in the Mataram City Government. The results of the study show that the arrangement of street vendors in the city of Mataram still cannot run effectively because there is still no regulation that should be followed up on by Regional Regulation Number 5 of 2010 along with the Mayor of Mataram Regulation Number 56 of 2017 concerning Instructions for the Implementation of Regional Regulation of Mataram City Number 10 of 2015 about street vendors, namely the zoning arrangement of street vendors. From a simple calculation carried out by the researcher, the potential PAD that is likely to be obtained from the business activities of street vendors is Rp. 4,026,000,000 (Four Billion Twenty-Six Million) collected on the basis of a business service levy due to the use of government-owned land in accordance with the Mataram City Regional Regulation Number 4 of 2017 concerning Amendments to Regional Regulation Number 16 of 2011 concerning Business Service Retribution. This value, if measured by its contribution to the percentage of the realization value of regional retribution in 2019, can be categorized in the "Medium" criteria, while when viewed from its contribution to the percentage of business service levies, it can increase up to 392.92% or the "Very High" category. So the researchers suggest accelerating the determination of the legality of determining the Mataram Mayor's Decree regarding the zoning of street vendors so that the potential for retribution on street vendors' activities on government land can be collected and can contribute to increasing Mataram City PAD.
