Bawean Island is a sheltered and clean coastal waters that can be exploited for mariculture, particularly seaweed. Due to its enclosed environment, the presence of different wastes, particularly microplastics, is deemed negligible. The purpose of this research is to investigate the prevalence of microplastics in numerous seaweeds on Bawean Island's southwest shore, as well as the viability of seaweed production. At a depth of 1-6 meters, samples of red, green, and brown seaweed were obtained and examined for microplastics by destroying the cell walls. At the two observation sites, water characteristics such as current, pH, salinity, TDS, DO, substrate, temperature, depth, and brightness were also monitored. Based on the results, the southwest coastal waters of Bawean were suitable for seaweed cultivation. Furthermore, the lowest-highest microplastic concentration was discovered in Gracillaria sp. 44±18 particles/100g, Halimeda sp. 52±16 particles/100g, Caulerpa sp. 94±31 particles/100g, and Sargassum sp. 251±59 particles/100g, with a form of microplastic found in fragments, fibers, and films. Various colors of microplastics were found. According to this study, seaweed can act as a vector for microplastics to infiltrate the food chain. This is indicated by the substantial accumulation of microplastics in cultivation potential zones of seaweed where there are fewer human activities. This microplastic accumulation could then occur at a higher trophic level, thus seaweed in nature must be quarantined and cleaned after cultivation to reduce the concentration of microplastic contamination.

“…C. taxifolia kaya akan molekul polimer (polisakarida) dan dapat hiperakumulasi ion logam berat dan dapat mengubahnya menjadi bentuk lunak dengan proses reduksi (bio). C. taxifolia mengandung kadar protein yang cukup tinggi dibandingkan dengan jenis Caulerpa lainnya, yakni sebesar 11,02 ± 0,33%, C. racemosa 10,41 ± 0,08% (Jumsurizal et al, 2021), dan C. lentillifera 5,62% (Tapotubun, 2018). Menurut Merdekawati (2009), C. taxifolia mengandung protein sebesar 10,7%, protein tersebut bertindak sebagai capping agent dalam sintesis nanopartikel ZnO dan terlibat dalam proses reduksi Zn 2+ menjadi Zn 0 (Peletiri et al, 2012 (Triyono, 2003).…”

Penelitian mengenai nanotechnology telah banyak dilakukan dalam merekayasa sifat-sifat material. Unsur Zink atau Seng (Zn) menjadi salah satu material yang dijadikan nanopartikel. Sintesis nanopartikel di antaranya dapat dilakukan dengan metode biosintesis, yaitu memanfaatkan tumbuhan (di antaranya adalah rumput laut hijau) dalam proses sintesis nanopartikel. Rumput laut hijau jenis Caulerpa taxifolia mudah ditemukan dan sangat melimpah di Pantai Teluk Sepang, Kota Bengkulu, namun selama ini penggunaannya belum dimanfaatkan secara optimal. Tujuan penelitian ini adalah melakukan proses ekstrak C. taxifolia untuk menghasilkan nanopartikel ZnO dan menjelaskan karakterisasinya. Nanopartikel ZnO C. taxifolia yang dihasilkan berupa bubuk ZnO berwarna putih susu (milky white). Analisis gugus fungsi ZnO C. taxifolia menunjukkan bahwa pita serapan yang muncul telah berada dalam rentang nilai spektral ZnO hasil penelitian sebelumnya. Hasil pencitraan SEM menggambarkan morfologi nanopartikel ZnO C. taxifolia yang terlihat tidak seragam dan umumnya berbentuk nanorod. Ukuran partikel ZnO sintesis ekstrak C. taxifolia cenderung bervariasi yaitu berkisar antara 1,28-1764,23 nm. Kurva menunjukkan distribusi ukuran partikel ZnO C. taxifolia dengan ratarata diameter 254,95 nm membuktikan ekstrak rumput laut C. taxifolia berhasil berperan sebagai agen penstabil, capping agent, dan agen pereduksi.
