<![CDATA[This article examines the effectiveness of Article 34 of West Pasaman Regency Regional Regulation Number 13 of 2018 concerning Public Security and Public Order, particularly the prohibition of wearing revealing clothing in entertainment venues, and analyzes it from the perspective of fiqh siyasah tanfidziyah. The implementation of this provision faces several challenges, including differing interpretations of the term "revealing clothing" and varying levels of public compliance. This study aims to identify the factors that support and hinder the enforcement of the provision and to assess its conformity with the principles of siyasah tanfidziyah. The research employs a normative-empirical legal research method with a descriptive qualitative approach, using field research conducted in Nagari Parit, Koto Balingka District. Primary data were collected through observation, structured interviews, and documentation, and were analyzed inductively using Soerjono Soekanto's theory of legal effectiveness. The findings indicate that the implementation of Article 34 is reasonably effective but not yet optimal. Supporting factors include the legal validity of the regulation, support from law enforcement officers and the nagari government, and its compatibility with local customs and religious values. Meanwhile, the inhibiting factors include the lack of a clear operational definition of "revealing clothing," limited institutional capacity and facilities, and the influence of external cultural values. From the perspective of fiqh siyasah tanfidziyah, the implementation of Article 34 is consistent with the objectives of maqashid al-shariah and is justified as an exercise of governmental authority within the framework of siyasah tanfidziyah wilayahiyah. These findings imply the need for implementing technical regulations to strengthen legal certainty and improve the effectiveness of enforcement at the nagari level.]]>
