Legal Literacy - Coastal boundaries are a very important area in maintaining coastal ecosystems and protecting communities from the threat of abrasion. However, this area is often forgotten in coastal area planning and management. According to the Indonesian Central Statistics Agency (2024), around 70% of Indonesia's coastline is experiencing abrasion, which can threaten the existence of ecosystems and the lives of coastal communities. In this context, regulations on abrasion-resistant plants are very important to prevent further damage and protect existing natural resources.

Good management of coastal boundaries not only protects ecosystems, but also provides economic benefits for the community. Abrasion-resistant plants, such as mangroves, have the ability to reduce the impact of sea waves and strengthen the soil around the coast. Data shows that mangrove planting can reduce wave speed by up to 70% (Nugroho, Setyandito, & Purwanto, 2020). Therefore, it is important for the government and the community to understand the urgency of regulating abrasion-resistant plants as a preventive measure in facing the threat of abrasion.

This paper will discuss various aspects related to the regulation of abrasion-resistant plants, from the definition and importance of coastal boundaries, to the challenges and solutions that can be applied. With a better understanding of this issue, it is hoped that a collective awareness will emerge to maintain and protect coastal boundaries that are often forgotten.
