This study discussed the macro and microplastics abundance on beaches of Malaysian islands namely, Pulau Besar, Langkawi Island, Sibu Island and Perhentian Island. The objectives of this study are to determine the current waste management and evaluate the cleanliness index (BCI) of the beach. It is also aimed to determine the composition of marine waste and abundance distributions of macro and microplastic as well as to determine their correlations. The BCI scores on each beach sites was evaluated by using a five point Likert scale ranged from 0 (very negative responses) to 4 (very positive responses). For the waste composition studies, debris on each beach sites were collected, weighed and counted after the segregation into 27 predetermined types. As for the microplastic quantification, a triplicate of 12.5 L of sediment samples was collected using 50 x 50 cm quadrat to a depth of approximately 5cm, at different tidal zones. The sediment samples were sieved to group them according to their respective sizes. Results indicated that, beach of Pulau Besar that faces the open sea was the cleanest with the highest BCI value (3). Recreational, fishing andUniversity shipping activities are the anthropogenic of activities Malaya conducted on all the beaches studied. Marine waste found on these beaches includes hard plastic, film, polystyrene, paper, aluminium cans, and drinking packs. The distributions of macro and microplastic debris in this study are dependent of the economic activities of the respective beaches. The quantity of macroplastics was highest in Pinang Seribu Beach (103 items/m2), followed by beach of Sibu Island that faces the mainland (76 items/m2) and Tanjung iii Butong Beach (60 items/m2). The highest quantity of microplastics were collected at Pinang Seribu Beach with 2517 items/m2 and followed by beach of Sibu Island that faces the open sea with 401 items/m2. While fishing beaches have abundant quantities of plastic line, foam and film, recreational beaches accumulated more plastic film, fragment and foamed plastic. Remote beaches on Perhentian Island had the highest quantity of plastic foam, fragment and line. In general, a positive correlation (0.917) with R2 = 0.841 was found between the abundance of macro and microplastics on the selected beaches of Malaysian islands. This demonstrates that continued cleaning efforts are crucial to reduce the plastic debris pollution on beaches of Malaysian islands.

Kajian ini membincangkan mengenai taburan makro dan mikroplastik di pantai- pantai pulau terpilih di Malaysia iaitu Pulau Besar, Pulau Langkawi, Pulau Sibu dan Pulau Perhentian. Kajian ini bertujuan untuk menentukan pengurusan sisa di kawasan pantai dan untuk menilai indeks kebersihan pantai. Kajian ini juga bertujuan untuk menentukan komposisi sisa-sisa marin dan taburan serta jumlah makro dan mikroplastik yang terdapat di pantai-pantai tersebut selain menentukan korelasi di antara taburan makro dan mikroplastik. Indeks kebersihan di setiap pantai dinilai dengan menggunakan skala Likert lima titik bermula dari skor 0 (tindak balas yang sangat negatif) kepada skor 4 (tindak balas yang sangat positif). Kesemua sisa di setiap pantai dikumpul, ditimbang dan dikira selepas diasingkan kepada 27 jenis sisa yang telah ditetapkan. Bagi kajian mikroplastik, triplikasi sampel pasir sebanyak 12.5 L diambil menggunakan kuadrat bersaiz 50 x 50 cm dengan kedalaman kira-kira 5 cm di kawasan pasang surut yang berbeza. Sampel-sampel pasir ini diayak untuk mengasingkan sisa mikroplastik mengikut saiz. Keputusan menunjukkan bahawa, kawasanUniversity pantai yang menghadap laut terbuka of di PulauMalaya Besar merupakan pantai yang paling bersih dengan nilai indeks kebersihan pantai yang paling tinggi (3). Aktiviti rekreasi, perikanan dan perkapalan merupakan aktiviti antropogenik yang terdapat di pantai-pantai kajian. Antara sisa-sisa marin yang terdapat di pantai kajian ialah plastik HDPE, filem, polistirena, kertas, tin aluminium dan kotak minuman. Taburan sisa makro dan mikroplastik dalam kajian ini bergantung kepada aktiviti ekonomi di pantai- v pantai kajian. Pantai Pinang Seribu mencatatkan jumlah makroplastik tertinggi (103 item/m2), diikuti oleh kawasan Pantai Pulau Sibu yang menghadap tanah besar (76 item/m2) dan Pantai Tanjung Butong (60 item/m2). Pantai Pinang Seribu juga mencatatkan jumlah mikroplastik yang paling tinggi (2517 item/m2) dan diikuti oleh kawasan pantai Pulau Sibu yang menghadap laut terbuka (401 item/m2). Kawasan pantai yang terkenal dengan aktiviti memancing dan petempatan nelayan mencatatkan jenis-jenis mikroplastik seperti tali, buih dan filem, manakala pantai rekreasi mencatatkan lebih banyak mikroplastik filem, pecahan dan buih. Pantai terpencil di Pulau Perhentian memperolehi jumlah buih, pecahan dan tali yang tinggi. Secara umumnya, terdapat korelasi positif (0.917) dengan R2 = 0.841 di antara taburan makro dan mikroplastik di pantai-pantai pulau terpilih di Malaysia. Hal ini menunjukkan bahawa usaha pembersihan pantai yang berterusan adalah sangat penting untuk mengurangkan pencemaran sisa plastik di pantai-pantai pulau di Malaysia.
