<![CDATA[Coastal areas like Kota Tua Ampenan Beach in Mataram hold significant historical, cultural, and tourism value, yet rising visitor and community activity has increased waste generation, threatening coastal sustainability. This activity aimed to identify the types and distribution of waste in the area and to raise community environmental awareness through education. A descriptive method with a participatory approach was used, involving direct observation, interviews, documentation, and environmental education for residents, vendors, and visitors. The observation results showed a total of 510 waste items, dominated by plastic waste (250 items, 49.0%), followed by wood branches and dried leaves (180 items, 35.3%), cans (50 items, 9.8%), and vegetable residues (30 items, 5.9%). The environmental education activities improved participants' understanding of the impact of waste on the coastal ecosystem and encouraged more environmentally responsible behavior, although littering was still observed. It can be concluded that plastic waste is the main pollutant at Kota Tua Ampenan Beach, while environmental education effectively increased community awareness and participation in coastal conservation. These findings imply the need for sustainable community-based waste management, including adequate facilities and ongoing education, to support the area's conservation.]]>
