ABSTRAKPerairan Kota Tanjungpinang memiliki kompleksitas tinggi dengan berbagai bentuk pemanfaatan lingkungan. Aktivitas tersebut menyebabkan peningkatan buangan bahan pencemar organik maupun anorganik ke perairan. Distribusi sampah laut yang tidak tenggelam ke dasar perairan akan hanyut dan mengendap di sepanjang pantai. Proses ini sangat dipengaruhi oleh faktor hidro-oseanografi seperti arus. Penelitian ini bertujuan untuk mengetahui keterkaitan arus laut terhadap distribusi sampah laut di perairan. Pengambilan sampel sampah laut menggunakan metode line transect untuk pengambilan sampel di pantai dan pengambilan sampel di laut menggunakan Manta Net. Pengukuran arus, pasang surut, batimetri dan kecepatan angin dilakukan secara langsung di lapangan. Analisis pola arus menggunakan model hidrodinamika untuk mensimulasikan pola arus di lokasi penelitian. Saat kondisi pasang, arus bergerak dari utara menuju selatan dengan kecepatan 0,15-0,24 m/s. Sedangkan saat surut, arus bergerak dari selatan menuju utara dengan kecepatan 0,00-0,09 m/s. Plastik merupakan jenis sampah laut dengan tingkat kepadatan tertinggi yang paling banyak ditemukan, baik yang berukuran makro maupun meso. Sirkulasi arus diduga memberikan pengaruh terhadap distribusi sampah laut di lokasi penelitian. Ketika perairan dalam kondisi pasang, sampah laut dengan massa yang lebih ringan akan terbawa ke pantai. Pada saat surut, kecepatan arus yang cenderung jauh lebih lemah menyebabkan sampah laut akan tertinggal di pantai.Kata kunci: Arus Laut, Hidro-Oseanografi, Kota Tanjungpinang, Sampah LautABSTRACTThe waters of Tanjungpinang City have a high complexity with various of environmental utilization. This activity leads to increased discharge of organic and inorganic pollutants into the waters. The distribution of marine debris that does not sink to the bottom of the water will be washed away and settle along the coast. This process is strongly influenced by hydro-oceanographic factors such as currents. This study aims to determine the relationship between ocean currents and the distribution of marine debris in the waters. Marine debris sampling using line transect method for beach samples and Manta Net for marine sampling. Measurements of currents, tides, bathymetry and wind speed are carried out directly in the field. Current patterns analysis using hydrodynamic models to simulate current patterns. During high tide conditions, the current moves from north to south at a speed of 0,15-0,24 m/s. While at low tide, the current moves from south to north at a speed of 0,00-0,09 m/s. Plastic is the highest density type of marine debris found, either macro and meso. Current circulation have an influence on the distribution of marine debris. At high tide conditions, marine debris with a lighter mass will be carried to the beach. At low tide, the speed of the current which tends to be much weaker causes marine debris to be left on the beach.Keywords: Hydro-Oceanography, Marine Debris, Sea Current, Tanjungpinang City

Sedimentation and erosion processes can be influenced by hydro-oceanographic factors. These factors include waves, currents, and tides because they interact directly with the coastal/coastal area. Related to these problems, sedimentation and erosion is one thing that needs to be studied. One way that is used in providing information about these that is widely used is to use a hydrodynamic model. Based on this, it can be seen that it is important to conduct research to determine sediment properties such as the type and type of sediment with sediment transportt modeling in Berakit and Pengudang villages. This research was carried out using the MIKE21 Software hydrodynamic modeling for one month in June 2021 using hydrodynamic modeling, the Flow Model FM Sand Transportt module. Sediment transportt observed is bottom sediment or bed load. The research results are shown in 4 conditions, namely towards high tide, highest tide, towards low tide and lowest tide. Sediment transportt at high tide with erosion of -0.10 and sedimentation of 0.25 m/day and at the highest tide shows an erosion value of -0.24 and sedimentation of 0.32 m/day. Sediment transportt towards low tide with erosion of -0.15 and sedimentation of 0.20 m/day and at the lowest ebb erosion occurs with a value of -0.36 and sedimentation of 0.20 m/day.

Ekosistem lamun dapat terganggu oleh berbagai faktor seperti perubahan suhu, polusi, kerusakan habitat, destructive fishing, dan pencemaran laut. Pemantauan kondisi lamun sangat penting dilakukan untuk memastikan keseimbangan ekosistem tetap terjaga, terutama pada daerah konservasi seperti di Desa Pengudang yang menjadi wilayah konservasi lamun. Salah satu cara yang dapat digunakan dalam mengamati kondisi ekosistem lamun untuk melihat perubahan yang terjadi adalah menggunakan kombinasi sistem informasi geografis dengan pengindraan jauh. Pada teknologi pengindraan jauh data yang digunakan yaitu Citra Sentinel-2A. Tujuan dari penelitian ini adalah memetakan luasan lamun di perairan Desa Pengudang dengan menggunakan Algoritma Lyzenga. Metode Lyzenga dikenal dengan nama metode depth-invariant index atau metode water column correction (koreksi kolom air). Koreksi kolom air bertujuan untuk mengeliminasi kesalahan identifikasi spektrum habitat karena faktor kedalaman selanjutnya dilanjutkan dengan proses supervised classification pada citra. Luasan lamun di perairan Desa Pengudang didapatkan berdasarkan hasil analisis klasifikasi terbimbing. Citra Sentinel-2A pada tahun 2018 mencapai angka 8.43 dan pada tahun 2020 mengalami penurunan dengan angka 7.30 hektar dengan nilai uji akurasi 80%. Penurunan luas padang lamun di perairan Desa Pengudang disebabkan oleh beberapa faktor, salah satunya adalah pencemaran minyak di wilayah Bintan yang terjadi secara teratur setiap tahun dan telah mempengaruhi kondisi ekosistem di wilayah tersebut. Seagrass ecosystems can be disturbed by various factors such as changes in temperature, pollution, habitat destruction, and human activities, including unsustainable fishing, marine pollution, and chemical use. Therefore, monitoring the condition of seagrass ecosystems is essential to ensure the balance of the ecosystem is maintained, especially in conservation areas. Pengudang Village is one of the villages that has been designated as a seagrass conservation area. One of the ways to observe the condition of seagrass ecosystems and detect changes is to use a combination of geographic information systems and remote sensing. The data used in remote sensing technology is the Sentinel-2A image. The purpose of this research is to map the seagrass area in the waters of Pengudang Village using the Lyzenga Algorithm, also known as the depth-invariant index method or water column correction method. The water column correction method aims to eliminate errors in habitat spectral identification due to depth factors before proceeding with the supervised classification process on the image. The seagrass area in the waters of Pengudang Village was obtained based on the results of the supervised classification analysis. The Sentinel-2A imagery in 2018 covered an area of 8.43 hectares, and in 2020, it decreased to 7.30 hectares with an accuracy test value of 80%. The decrease in the seagrass area in the waters of Pengudang Village is caused by several factors, one of which is oil pollution in the Bintan region, which occurs regularly every year and has affected the condition of the ecosystem in the region.

Penelitian ini bertujuan untuk mengetahui jarak dan laju perubahan garis pantai yang terjadi di Pantai Tanjung Siambang menggunakan citra satelit Sentinel-2A. Metode yang digunakan untuk menghitung perubahan garis pantai yaitu metode Net Shoreline Movement (NSM) dan End Point Rate (EPR) yang terdapat dalam Digital Shoreline Analysis System (DSAS). Hasil penelitian menunjukkan bahwa selama 5 tahun terakhir, Pantai Tanjung Siambang mengalami abrasi dengan rata-rata perubahan sebesar -10.18 meter dengan laju -2.12 meter/tahun. Akresi juga terjadi dekat muara sungai dengan rata-rata akresi sebesar 1.43 meter dan laju 0.3 meter/tahun. Secara keseluruhan, pada periode 2016-2021 Pantai Tanjung Siambang dominan mengalami pengurangan daratan (abrasi). Pemanfaatan data penginderaan jauh dan berbagai software pengolahan data penginderaan jauh sangat bermanfaat untuk penyediaan informasi mengenai perubahan garis pantai yang akan berguna dalam pengambilan kebijakan terkait pembangunan di wilayah pesisir dan juga pencegahan atau mitigasi terhadap kemungkinan bencana yang akan terjadi di wilayah pantai tersebut.Kata Kunci: Abrasi, Akresi, Citra Satelit Sentinel-2A, Digital Shoreline Analysis System, Pantai Tanjung SiambangABSTRACTTanjung Siambang Beach is a tourist spot that is vulnerable to natural influences because it has a sloping topography, sandy and muddy substrate and lots of human activities. This affects the position of the coastline at Tanjung Siambang Beach from year to year, so it is necessary to conduct research to monitor shoreline changes that occur on the beach. This study aims to determine the distance and rate of change of coastline that occurs at Tanjung Siambang Beach using Sentinel-2A satellite imagery. The methods used to calculate shoreline changes are the Net Shoreline Movement (NSM) and End Point Rate (EPR) methods contained in the Digital Shoreline Analysis System (DSAS). The results showed that during the last 5 years, Tanjung Siambang Beach experienced abrasion with an average change of -10.18 meters at a rate of -2.12 meters/year. Accretion also occurs near river mouths with an average accretion rate of 1.43 meters and a rate of 0.3 meters/year. Overall, in the 2016-2021 period Tanjung Siambang Beach has predominantly experienced land reduction (abrasion). Utilization of remote sensing data and various remote sensing data processing software is very useful for providing information about changes in the coastline that will be useful in making policies related to development in coastal areas as well as prevention or mitigation of possible disasters that will occur in these coastal areas.Keywords: Abrasion, Accretion, Sentinel-2A Satellite Imagery, Digital Shoreline Analysis System, Tanjung Siambang Beach
