In this case, the analysis used is qualitative data analysis, namely data that cannot be measured or assessed with numbers directly. Thus, after the primary data and secondary data in the form of documents are obtained completely, then they are analyzed with regulations relating to the problem under study.From the results of research conducted that the role of the Regional Revenue Unit of Mandau District, Bengkalis Regency in collecting hotel taxes in terms of Article 17 of the Bengkalis Regency Regent Regulation No. 17 of 2012 concerning Instructions and Implementation of Hotel Taxes can be said to have not run optimally.
