Penentuan Jenis Citra Satelit Dalam Interpretasi Luasan Ekosistem Lamun Menggunakan Pengolahan Algoritma Cahaya Tampak

Abstract: <h4>Peran dan manfaat ekosistem lamun secara ekologis merupakan hal yang harus diamati secara terperinci, terlebih potensi kerusakan yang dapat terjadi. Pemantauan kondisi ekosistem tersebut dapat dilakukan dengan memanfaatkan teknologi penginderaan jauh. Dalam penelitian ini, algoritma Lyzenga digunakan untuk mengolah nilai piksel yang ada pada citra satelit Landsat-8 dan Sentinel-2. Aplikasi algoritma Lyzenga akan menghasilkan nilai yang menunjukkan identitas dari objek yang terdapat di perairan pesisi… Show more

“…Satelite data using Sentinel-2A which is a polar-orbit satellite launched by European Space Agency (ESA). Sentinel-2A has 13 bands with a spatial resolution of 10 m and 20 m and acquisition from the website of https://scihub.copernicus.eu/dhus/ (Yanuar et al, 2018) . Field variable measured are seagrass species, density, chlorophyll-a, biomass and carbon.…”

“…The user accuracy value is an accuracy value that shows the right classification class based on the field data and the producer accuracy value is the accuracy value in the classified class from the classification results [31]. While the overall accuracy value is an overall picture of the error rate of image data processing that is applied, where the closer to the maximum value, the smaller the error data generated [32][33]. Table 8 shows the results of the calculation of the accuracy-test using the confusion matrix method for the classification of Sentinel-2 images in 2019 and Unmanned Surface Vehicle field data.…”

“…For example, the producer accuracy value is influenced by the calculation factor of the Lyzenga algorithm, while the user accuracy value is influenced by the input or calculation process. In addition, factors such as training samples, correction process, spatial resolution, GPS accuracy also affect the accuracy value obtained [32]. Please explain why such things have influenced the result of the accuracy test.…”

“…Waktu pengolahan citra Sentinel-2 sedikit lebih lama dari Landsat 8 tetapi lebih cepat dibandingkan SPOT 7. Resolusi pada citra Landsat 8 dan Sentinel-2 termasuk menengah karena memiliki resolusi 30 m dan 15 m, sedangkan SPOT 7 merupakan citra yang memiliki resolusi tinggi yaitu 6 m. Hal ini sesuai dengan pengelompokkan resolusi spasial (Yanuar et al 2018) sebagai berikut: 30m -1.000 m (resolusi rendah), 5 -30 m (resolusi menengah), dan 0,4 -5 m (resolusi tinggi). Menurut Oktaviani dan Johan (2016) waktu pengolahan citra Sentinel-2 hampir sama dengan citra Landsat 8 karena keduanya tidak memakan waktu lama, tetapi untuk citra SPOT 7 cukup lama karena memiliki resolusi tinggi sehingga membutuhkan ruang data yang lebih besar Biaya Sentinel-2 sama dengan Landsat 8 karena keduanya bisa didapatkan secara gratis, berbeda dengan SPOT 7 yang membutuhkan biaya yang cukup mahal untuk mendapatkannya.…”
