I Indonesia has both constitutional and international obligations to preserve the environment and wildlife, including species listed in the cites appendices. batam city, particularly the industrial area of tanjung riau, is vulnerable to the illegal trade of protected wildlife due to its strategic location along international transit routes.the issue addressed in this study is: what efforts have been made by the batam city government to protect the sustainability of appendix-listed wildlife and the environment in the tanjung riau industrial area based on batam city regional regulation no. 8 of 2014, and what obstacles does the batam city government face in protecting the sustainability of appendix-listed wildlife and the environment in the industrial area, as well as the possible solutions?this thesis employs normative legal research with a descriptive approach, using secondary data analyzed qualitatively and drawing conclusions through a deductive method.the findings of the study indicate that protective efforts include monitoring activities at ports and airports, public education, and legal enforcement. however, these efforts have not been fully effective and require revision. human resource limitations, lack of active cooperation from the city government, and minimal community participation exacerbate the situation. the complexity of smuggling networks, supported by the border location, weak supervision, and rapid movement of goods, poses major challenges and risks of exploitation.therefore, optimal implementation of central resources, increased collaboration and synergy with the city government through memorandums of understanding (mous), utilization of modern technology, and enhanced public participation are necessary.
