Abstract

Sea water intrusion is a process where sea water is mixed with underground water around the coast, causing the ground water to become salty because it is contaminated by sea water which is rich in salt. Sea air that enters the ground causes the air to become unfit for consumption and causes the land to become unproductive for planting. People in the Pakis Jaya area, Karawang face difficulties, especially regarding land use for agricultural activities. This is because the land used for cultivating plants is saline soil with a high salt content. Phytoremediation is a method used to clean air or soil contaminated with pollutants, by using the ability of plants to absorb these substances. Cynodon Dactylon and lolium Perenne Brightstar plants are a type of grass that can be used to reduce high salt levels in the soil because these plants are able to live in places with high salinity and also have the ability to reduce salinity by absorbing chloride ions in it. The methods used in this research consisted of: Sampling Process, Plant Acclimatization Stage, Salinity Concentration Test before and after planting grass in Soil Media. The test results showed that the salt content in the soil before planting was 19.20 dS/m and after planting it was 0.02-0.03 dS/M.

Abstract

This research is focused on conflict management of school discipline policies carried out by the school to late students entering school. The background of the research is that there are many violations of the rules, especially in terms of being late for school. The research was conducted with the aim of knowing the factors of being late for school and the implementation of conflict management policies on school discipline in handling students late for school at SMA Negeri 1 Tamanan. The research conducted is descriptive qualitative, namely research that produces data in the form of descriptive or written or unwritten words from sources. Informants in the study were counseling teachers, student teachers, and 5 students who were often late for school at SMA Negeri 1 Tamanan. Data collection techniques using observation and interviews. As for the research results obtained, namely the factor of students entering school late comes from self factors and school discipline policy factors. The application of conflict management policies for school discipline in handling students late for school is by giving points, encouraging motorbikes and reprimands when entering class by the teacher who is teaching.

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

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.
