Abstract

The Togean Islands, located in Tomini Bay, Central Sulawesi, Indonesia, are part of the coral triangle that encompasses the waters of Indonesia, the Philippines, Malaysia, Papua New Guinea, Japan, and Australia. This region hosts a coral reef ecosystem that relies on ocean currents for nutrient distribution and coral larval dispersal. Maintaining the balance and health of ocean currents is crucial for the sustainability of this ecosystem. This study aims to map ocean current patterns in the waters of the Togean Islands during the 2021–2022 period using data from Copernicus Marine. A secondary data analysis with a descriptive approach was employed. Data were obtained from the Copernicus Marine platform and processed using SeaDAS and ArcGIS software. In 2021, the recorded current speed was relatively lower, ranging from 0.04 m/s to 0.16 m/s, whereas in 2022, the current movement was stronger, with an average speed ranging from 0.06 m/s to 0.21 m/s. The comparison of ocean currents in the Togean Islands showed peak values in December for both years, while the lowest average speeds were recorded in March 2021 and October 2022. These current patterns are influenced by seasonal factors and play a significant role in marine ecosystem dynamics. This mapping is expected to serve as a reference for the management and conservation of coral reefs in the Togean Islands.

Abstract

Mangrove forests are types of vegetation that grow under the influence of the rising and falling sea water. They play a crucial role ecologically, physically, and economically. However, without proper management, this ecosystem is at risk of harm. In Segarajaya Village, Tarumajaya District, Bekasi Regency, West Java, mangrove forests are threatened by human activities, such as clearing land for fish farming without preserving mangrove vegetation, along with pollution from plastic and household waste. This study aimed to assess the health of mangroves based on two aspects: (1) MHI parameters, which include canopy cover, individual density, and stem diameter; and (2) environmental parameters, which consist of salinity, water and air temperature, soil pH, and substrate type. The method employed is the Mangrove Health Index (MHI), which involves calculating the parameters of canopy cover, stake density, and average stem diameter at breast height, along with environmental parameters (salinity, water and air temperature, soil pH, and substrate) conducted from February 25 to April 20, 2025. The observation site was divided into three stations. Station 1 had the species Rhizophora apiculata, Avicennia marina, and Sonneratia caseolaris. Station 2 was populated with Bruguiera gymnorhiza and Sonneratia caseolaris, while Station 3 only contained Avicennia marina. The MHI value calculations indicated that the mangrove forest's condition falls into the moderate category, with an average MHI value of 61.78%. Station 1 recorded 62.69%, Station 2 61.63%, and Station 3 61.02%. The average values of environmental parameters were a salinity of 30.44‰, water temperature of 27.94°C, air temperature of 30.89°C, soil pH of 7.33, and substrates consisting of sandy clay and mud. This study aims to inform readers about the health conditions of mangroves and serve as a foundation for managing and protecting mangrove forests.

Abstract

Bathymetry studies the depth and topographic features of the seabed, which aremapped using underwater acoustic technologies such as Multibeam Echosounder. This research was conducted in the Setangga Waters, Tanah Bumbu Regency, South Kalimantan Province, using a Multibeam Echosounder T-20P. Data acquired from a four-day survey were processed using PDS software, including data cleaning, Sound Velocity Profile (SVP) correction, and tidal correction. Tidal data were processed using LP-TIDES software based on 26 days of observations, resulting in a Mean Sea Level (MSL) value of 1.08 meters. All data met the International Hydrographic Organization (IHO) standards, and the final results were presented in the form of a Digital Elevation Model (DEM) and depth contour maps that accurately represent the seabed morphology.

Abstract

This study explores the application of underwater 3D photogrammetry and accuracyevaluation in measuring coral reef volume in the northern waters of Tunda Island. The global decline in coral populations—due to environmental stressors such as rising sea temperatures, predation, and destructive human activities— necessitates accurate and non-destructive monitoring methods. 3D photogrammetry allows digital recording of coral shapes in three dimensions by processing underwater images using Agisoft Metashape and analyzing volume through MeshLab. The research focuses on three coral growth forms: branching, massive, and foliose, using varying numbers of photos (50, 100, 150, 200, and 250) to assess their impact on model accuracy. Results indicate that while more photos generally improve accuracy, this relationship is not always linear. For example, foliose corals showed a slight decrease in accuracy at 250 photos due to increased error points. Volume values remained relatively consistent despite accuracy variations. Several factors influenced reconstruction accuracy, including light conditions, water turbidity, current velocity, and camera positioning. Among all photo counts, 150 photos emerged as the most ideal—offering high accuracy with significant efficiency in data acquisition, storage, and processing time. This optimal balance makes it suitable for repeated monitoring efforts. In conclusion, this study demonstrates that underwater 3D photogrammetry is a practical and effective method for coral growth assessment. It supports the development of sustainable coral reef monitoring techniques that provide detailed, repeatable, and non-invasive data, crucial for marine conservation efforts.

Abstract

Tunda Island in Serang Regency, Banten Province, hosts a mangrove ecosystem with significant carbon storage potential, yet remains underutilized in climate mitigation efforts. This study aims to estimate the carbon stock of mangrove vegetation, focusing on leaf and branch components using both destructive and non-destructive methods. Samples were collected from six stations using line transect and 10×10 meter plot techniques. The identified mangrove species included Rhizophora apiculata, Rhizophora stylosa, Avicennia marina, Avicennia officinalis, and Bruguiera gymnorrhiza. Results showed estimated biomass ranging from 0.001757 to 0.024657 tons/ha, while carbon stock in leaves and branches ranged from 0.01197–0.01791 tons/ha and 0.02559–0.04184 tons/ha, respectively. Variations in carbon stock were influenced by dominant species, vegetation density, tree diameter (DBH), and environmental factors. The relatively low carbon values suggest that the mangrove ecosystem in Tunda Island is still in a developing phase. This highlights the need for sustainable conservation and rehabilitation efforts. The findings serve as a scientific foundation for coastal ecosystem management and blue carbon strategies in mitigating climate change.

Abstract

Mangrove forests thrive under tidal influences and play vital ecological, physical, and economic roles. However, without proper management, they are prone to degradation. In Segarajaya Village, Tarumajaya District, Bekasi Regency, West Java, mangroves face threats from human activities such as land clearing for aquaculture and pollution from plastic and domestic waste. This study, conducted from February 25 to April 20, 2025, used the Mangrove Health Index (MHI) method by assessing canopy cover, density, stem diameter, and environmental factors (salinity, water and air temperature, soil pH, and substrate). The aim was to evaluate mangrove health based on these parameters. Three observation stations were established: Station 1 (Rhizophora apiculata, Avicennia marina, Sonneratia caseolaris), Station 2 (Bruguiera gymnorhiza, Sonneratia caseolaris), and Station 3 (Avicennia marina). The MHI results indicated a moderate health status with an average value of 61.78% (Station 1: 62.69%, Station 2: 61.63%, Station 3: 61.02%). Environmental conditions averaged 30.44‰ salinity, 27.94°C water temperature, 30.89°C air temperature, soil pH 7.33, and sandy clay to muddy substrates. The study provides baseline data for mangrove management and conservation efforts.
