Sampah laut, khususnya plastik, merupakan masalah serius di kawasan pesisir karena dapat merusak ekosistem dan mengganggu aktivitas wisata maupun perikanan. penelitian ini bertujuan menganalisis jenis, kepadatan, dan berat sampah makroplastik di pantai manohara, kecamatan meureudu, kabupaten pidie jaya, aceh. pengambilan sampel dilakukan pada februari 2025 di tiga stasiun yang mewakili area wisata, aktivitas nelayan, dan muara. metode transek digunakan untuk mengumpulkan sampah makroplastik (>2,5 cm) yang kemudian diidentifikasi, ditimbang, dan dihitung kepadatannya. hasil penelitian menunjukkan bahwa makroplastik didominasi gelas plastik, kemasan makanan, dan tali rafia, dengan kepadatan tertinggi 0,32 unit/m² di stasiun iii. berat makroplastik terbesar tercatat pada kemasan makanan di stasiun ii sebesar 11,856 g/m², variasi jenis dan jumlah sampah dipengaruhi aktivitas manusia, terutama wisata dan perikanan. hasil ini menegaskan perlunya strategi pengelolaan pesisir serta peningkatan kesadaran masyarakat untuk mengurangi pencemaran plastik di pantai manohara. kata kunci : sampah laut, makroplastik, pantai manohara, pidie jaya

Marine debris, especially plastic, is a serious problem in coastal areas because it can damage ecosystems and disrupt tourism and fishing activities. This study aims to analyze the types, density, and weight of macroplastic debris on Manohara Beach, Meureudu District, Pidie Jaya Regency, Aceh. Sampling was conducted in February 2025 at three stations representing tourist areas, fishing activities, and estuaries. The transect method was used to collect macroplastic (>2.5 cm), which was then identified, weighed, and counted for density. The results showed that macroplastics were dominated by plastic cups, food packaging, and raffia ropes, with the highest density of 0.32 particles/m² at Station III. The highest weight of macroplastics was recorded in food packaging at Station II at 11.856 g/m². Variations in the type and amount of waste were influenced by human activities, particularly tourism and fishing. These results emphasize the need for coastal management strategies and increased public awareness to reduce plastic pollution on Manohara Beach.
