Abstract

Jakarta Bay is a coastal area influenced by both natural factors (wind, currents, waves) and human activities (residential areas, coastal development, industry, and resource exploitation). The monsoon phenomenon in the Java Sea affects hydrodynamic patterns, especially current dynamics in Jakarta Bay. This study analyzes changes in current patterns during two distinct monsoon seasons (west and east) in 2021 using a hydrodynamic modeling approach. The model was developed using OpenFlows software with input data including bathymetry, tidal, wind, and wave conditions. Model validation was conducted using tidal and current measurements from field observations in March and August 2021. The results show seasonal variations in current direction and velocity, both in tidal phases and non-tidal (residual) currents. The current patterns aligned with seasonal wind directions, indicating a strong monsoonal influence. Model validation using Root Mean Square Error (RMSE) and Taylor diagram analysis demonstrated good agreement between modeled and observed data, confirming the model's reliability. These hydrodynamic modeling results can serve as a foundation for further studies, such as simulations of pollutant, sediment, and debris dispersion in Jakarta Bay.

Abstract

Turbidity is a parameter of the marine environment that greatly affects the condition of seagrass whose habitat is an intertidal zone in shallow sea waters. Seagrass is an important type of ecosystem that can be found in several coastal areas of Ternate Island. This study aims to analyze the turbidity conditions of seagrass habitat waters and apply a remote sensing algorithm using Sentinel 2B images. The turbidity research method was carried out by field measurements. The turbidity algorithm model used refers to references with mathematical equations (Rrs665-0.014)/0.013, and the development of a new algorithm as a comparison algorithm. Both algorithms were validated with field data to determine the level of accuracy using the Normalized Mean Absolute Error (NMAE) and determination coefficient (R2). The results were obtained from turbidity data with values ranging from 0.3 NTU to 1.5 NTU with an average value of 0.87 0.45 NTU. The Sentinel 2B image in this study was restored with geometric corrections, atmosphere, radiometric digital values, land masking, and sun glint. The turbidity algorithm model used obtained good accuracy in mapping and monitoring the turbidity of seagrass habitat waters on Ternate Island. The application of the turbidity algorithm used as a reference in this study has an NMAE value of 50.44 and R2 of 0.8822, while the newly discovered turbidity algorithm has an NMAE value of 29.38 and R2 of 0.8827.Keywords:remote sensingecosystemscoastalsedimentationNorth Maluku

Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic species in the Halmahera Sea. Information related to the environment in general has not been described in a complex manner. The environment is the main factor to support the life of biota. Environmental characteristics are a determining factor in the sustainability of biota. The study aims to provide information related to the physical environment of the habitat of the H. halmahera species. Primary data collection was carried out directly (in situ). Current data was taken using the Lagrange method using a currents drogue. Tides using tidal palms and observed for 24 hours. Secondary data was taken from Marine Copernicus and the Geospatial Information Agency (BIG). All data were tabulated and analyzed by Ocean Data View (ODV) software. The results of the study found that the surface current velocity was found to be in the fast current category. Current speed descriptively provides information on the life of H. halmahera. Primary data shows that the direction of the surface current moves to the east and north. Secondary data in vertical distribution shows weak zonal and meridional current shifts. The tidal pattern was found to be two high and low tides (semidiurnal). The distribution of surface temperature was found to be around 30-32oC. The vertical temperature profile found three layers, namely 1-13m (30oC), 65m (25oC) and 71m (20oC). The chemical environment showed all normal variables. The physical and chemical environmental conditions support H. halmahera to inhabit the sea area of Morotai Island. The environmental description has provided a brief understanding of how the ecological role of the H. halmahera species. Management and sustainability of the environment in the future due to climate change can be done with information on habitat characteristics.Keywords:coral triangleHalmaheranicheNorth Malukutropical

Abstract

Perubahan garis pantai merupakan proses yang terjadi akibat adanya pengaruh dari kondisi pantai dalam mencapai keseimbangan terhadap dampak yang terjadi dari faktor alami dan kegiatan manusia. Secara geografis, wilayah pesisir pantai Kabupaten Tanah Laut Kalimantan Selatan mencakup dua wilayah yang berada di tepi barat dan tepi selatan. Secara fisik wilayah ini dipengaruhi oleh dinamika oseanografi dari perairan Laut Jawa serta aliran Sungai Barito yang bervariasi secara musiman. Penelitian ini bertujuan untuk menganalisis perubahan garis pantai di wilayah pesisir Pantai Barat Kabupaten Tanah Laut, Kalimantan Selatan. Data yang digunakan adalah citra Landsat 8 tahun 2016 untuk menggambarkan kondisi terkini dan citra Landsat 7 tahun 2003 sebagai kondisi awal. Citra tersebut dianalisis untuk dipetakan perubahan garis pantai yang mengalami akresi atau abrasi. Hasil penelitan menunjukkan bahwa garis pantai wilayah studi mengalami perubahan, dimana sebagian telah mengalami abrasi dan sebagian garis pantai telah mengalami akresi. Secara keseluruhan garis pantai wilayah Pantai Barat Kabupaten Tanah Laut dominan mengalami akresi dibandingkan abrasi karena adanya proses sedimentasi tinggi dari sungai Barito. Tetapi, di segmen garis pantai sel 3 dan 4 telah mengalami abrasi, meskipun area ini dekat dengan estuari Sungai Barito.

Abstract

The benthic habitats of shallow waters of Sebaru Island and Lancang Island have different water characteristics from geographical location. Data and information about benthic habitat are needed to maintain and preserve ecosystems in the waters. This study aims is to know the effect of different satellite image resolution, different algorithms and water quality e.g chlorophyll-a (Chl-a) and total suspended solid (TSS) on the accuracy of shallow-water benthic habitats mapping on Sebaru Besar Island and Lancang Island. The accuracy (OA) of the application of different classification algorithms showed a good results. The highest OA results in shallow waters of Sebaru Island with Wordview 2 imagery were obtained from the SVM and DT algorithms with the same value of 76.24%, while the Sentinel 2B image with the DT algorithm obtained results (OA) of 68.08%. In Lancang Island the highest OA value of Wordview 2 imagery was obtained by DT algorithm with a value of 74.44%, while Sentinel 2B imagery was obtained from KNN algorithm with a value of 59.0%. High concentrations of Chl-a and TSS cannot yet be said to affect the low accuracy in mapping shallow water benthic habitats.
