Abstract

Perubahan iklim secara langsung menyebabkan terjadinya kenaikan muka air laut bagi wilayah kepesisiran. Hal ini menyebabkan garis pantai menjadi tidak stabil, sehingga perlu untuk dilakukan pemantauan secara spasial dan temporal. Pulau Karimunjawa dan Kemujan merupakan dua pulau kecil dengan garis pantai yang saling terhubung oleh hutan mangrove. Penelitian ini bertujuan untuk mengidentifikasi dinamika garis pantai Pulau Karimunjawa dan Kemujan tahun 2000 – 2030. Identifikasi garis pantai tahun 2000 – 2020 diperoleh melalui ekstraksi garis pantai metode single band (B5) dan band ratio (B4/B2 dan B5/B2) citra Landsat 7 ETM+, sedangkan untuk identifikasi garis pantai tahun 2030 diperoleh melalui prediksi garis pantai metode Kalman Filter Model. Hasil penelitian menunjukkan bahwa garis pantai cenderung mengalami akresi dengan rata-rata perubahan garis pantai sebesar +0,76 meter per tahun dan diprediksi akan mengalami kemajuan garis pantai rata-rata sebesar +1,02 meter per tahun. Garis pantai daerah penelitian tergolong stabil dengan sedikit akresi (akresi sedang).Climate change causes sea level rise for coastal region. This causes the shoreline become unstable, so spatial and temporal monitoring is necessary. Karimunjawa and Kemujan Islands are two small islands with a shoreline [H1] that are connected by mangrove forests. This research aims to identify shoreline dynamics of Karimunjawa and Kemujan Islands in 2000 – 2030. The identification of shoreline in 2000 – 2020 was obtained through the extraction of shoreline using single band (B5) and band ratio (B4/B2 and B5/B2) method from Landsat 7 ETM+, while for identification of shoreline in 2030 was obtained through shoreline forecasting using Kalman Filter Model method. The results show that the shoreline tends to be accreted with an average shoreline change of +0.76 meters per year and predicted to be accretion with an average shoreline change of +1.02 meters per year. The Shoreline of the study area is [H2] relatively stable with little accretion (medium accretion).

2000-2030年卡里蒙贾瓦岛海岸线和事件的动态

气候变化直接导致总统的海面上升。这导致海岸线变得不稳定，因此有必要进行空间和时间监测。Karimunjawa和Kemujan是两个小岛，海岸线由红树林连接。本研究旨在确定卡里蒙贾瓦岛海岸线的动态和2000-2030年的老龄化。2000-2020年海岸线识别是通过提取单波段（B5）和波段比（B4/B2和B5/B2）Landsat 7 ETM+获得的，而对于2030年海岸线标识，则是通过预测卡尔曼滤波模型方法海岸线获得的。研究表明，海岸线往往会发生剧烈变化，平均海岸线每年变化+0.76米，预计海岸线平均每年进展+0.02米。气候变化导致沿海地区海平面上升。这导致海岸线变得不稳定，因此有必要进行空间和时间监测。Karimunjawa和Kemujan群岛是两个由红树林连接的海岸线为[H1]的小岛。本研究旨在确定2000年至2030年卡里蒙贾瓦群岛和克穆詹群岛的海岸线动态。2000-2020年的海岸线识别是通过使用Landsat 7 ETM+的单波段（B5）和波段比（B4/B2和B5/B2）方法提取海岸线获得的，而2030年的海岸线上识别则是通过使用卡尔曼滤波器模型方法进行海岸线预测获得的。结果表明，海岸线倾向于以每年+0.76米的平均海岸线变化进行吸积，并预测为以每年+1.02米的平均岸线变化进行吸藏。研究区域的海岸线为[H2]Ş，相对稳定，几乎没有吸积（中等吸积）。

期刊介绍： The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
