The presence of microplastics adversely affects the presence of toxic absorbs such as PBTs (persistent, bioaccumulative, and toxic substances) and POPs (persistent organic pollutants). The process of degradation of plastic waste into microplastics can be through natural and chemical processes. Plastic type waste and synthetic / elastic will be difficult to decompose naturally. The increase in population will have an impact on the value of consumption so that it has an impact on individual or household waste production. Residents have the potential to move from one place to another in making tourist visits to water areas. As a result of poor behavior, garbage has the potential to be thrown anywhere. The types of waste found are plastic, cigarette wraps and butts, thread, nylon, bottles, plastic materials and other types. The research method used is an approach to scientific journals on various platforms (Mendeley, Google, University Journals and so on). Plastic decomposition will decompose in the soil very slowly and takes up to 1000 years, even waste from plastic bottles can decompose within 450 years to degrade to make microplastics. Microplastics are found in marine life such as fish, snails and sediments in waters. Microplastics are found in several types, namely pellets, fragments, fibers, Styrofoam films, and foams. The shape or type that dominates is the shape of fiber. Microplastics have an adverse impact on the health of organisms in the waters, including disorders of organisms in the waters are disorders of endoctrination, metabolism, tissue destruction, inflammation and growth disorders and decreased survival.

Terjadinya perubahan penggunaan lahan pada kawasan waduk dapat menurunkan fungsi hutan dalam penyerapan dan mentransfer air dan fungsi lainnya air. Tujuan penelitian adalah melakukan prediksi potensi perubahan tutupan lahan dan pengaruhnya terhadap waduk Sungai Pulai Kota Tanjungpinang Provinsi Kepulauan Riau. Metode yang digunakan adalah kuantitatif dengan pengukuran evapotranspirasi dengan Model Penman dan debit andalan menggunakan Model FJ Mock dengan mempertimbangkan data klimatologi dan hidrologi dan analisis spasial. Hasil perhitungan evapotranspirasi berkisar antara 2,78 mm/H hingga 4,64 mm/H dan diintegrasikan kedalam perhitungan debit andalan pada tahun 2023, dengan hasil Debit hitung antara 0,138 m3/detik s.d. 0,605 m3/detik yang dipengaruhi oleh faktor curah hujan diatas 100 mm/bulan. Pada Catchment Area (CA) seluas 409,85 Ha penggunaan lahan hutan/bervegetasi diperkirakan sebesar 172,52 Ha (42 %). Dengan luas lahan terbuka sebesar 236,17 Ha (58 %) maka diprediksi potensi penyimpanan air sebanyak 213.939 m3/tahun dan transfer air sebesar 347.057.329 liter/Tahun. Jika CA yang dapat ditumbuhi pohon besar seluas 350 Ha maka dapat diprediksi Potensi menyimpan air sebesar 315 m3/tahun dan potensi transfer air sebesar 511.000.000 liter/Tahun. Oleh karena itu perlu dilakukan langkah kuratif untuk menjaga keseimbangan ekosistem sumber daya air pada waduk yaitu dengan melakukan langkah reforestasi terhadap CA yang terdegredasi. Untuk penelitian lebih lanjut agar dapat dilakukan penelitian tentang pengaruh evapotranspirasi pada setiap penggunaan lahan.

This study compares the growth of two seaweed species, Kappaphycus striatus and Kappaphycus alvarezii (green variety), using the longline method in the waters of Pelakak Village, Lingga Regency. This research aims to identify differences in daily growth rates and environmental factors affecting the productivity of both seaweed species. The study was conducted over 45 days using a randomized block design with two treatments and four replications. Measured parameters included absolute weight growth, specific growth rate, and water quality. The results showed that K. alvarezii (green variety) exhibited a higher daily growth rate (0.55% weight/day) compared to K. striatus (0.31% weight/day). Environmental factors such as temperature (28–30°C), salinity (30–31 ppt), and pH (7.1–7.4) were within the optimal range, but the current velocity (0.4–0.5 m/s), which exceeded the standard, potentially inhibited growth an increased the risk of talus damage. The t-student test indicated no significant difference in growth between the two seaweed species (p>0.05). These findings suggest that K. alvarezii (green variety) is more adaptive to local environmental conditions than K. striatus, although current velocity and pest presence remain challenges in seaweed cultivation. This study contributes to optimizing seaweed farming strategies in coastal areas. Keywords: Growth; Kappaphycus striatus; Kappaphycus alvarezii Green Variety; Longline
