THE EFFECT OF ENSO ON RAINFALL AND CHLOROPHYLL-A VARIABILITY IN THE WATERS OF PULAU LAUT
type: item
description: The waters of Pulau Laut have considerable marine and marine resource potential. The waters of the Pulau Laut cluster have been studied for the feasibility of mariculture (cage farming, floating nets) based on oceanographic and water chemistry parameters. Coastal areas and small islands such as Pulau Laut are also seen as potential locations for marine ecotourism development. This study aims to analyze the influence of the El Niño Southern Oscillation (ENSO) phenomenon on rainfall variability and chlorophyll-a concentration in the Pulau Laut waters. This study is relatively new, considering that there are not many previous studies that specifically discuss the relationship between ENSO, rainfall, and chlorophyll-a in this area. This study uses satellite-based observation data. The rainfall and chlorophyll analyzed cover a 16-year period, from 2007 to 2022. The rainfall data was taken from the Global Satellite Measurement of Precipitation (GSMaP) available through JAXA Global Rainfall Watch with a spatial resolution of 0.10°. Chlorophyll-a concentration data were obtained from the Ocean Color CCI (OC-CCI) Level 3 Standard (L3S) product provided by Marine Copernicus. The research method refers to a quantitative approach as described by, where numerical data are statistically analyzed and displayed through graphs and maps as a form of visualization. All temperature, wind, chlorophyll, and rainfall data are processed spatially using IDL (Interactive Data Language) software. Analysis of the relationship between ENSO and rainfall and chlorophyll-a in the waters of Pulau Laut shows that in the west season there is no significant relationship between ENSO and rainfall, indicated by a p-value of 0.595 (>0.05) with a correlation of -0.079, reflecting a very weak negative relationship. In the east season, the relationship becomes significant, with a p-value of 0.008 and a correlation of -0.378, indicating that the stronger El-Nino, the rainfall tends to decrease. In the west s…

type: item
description: Abstract The study was conducted in Pejarakan Village, Gerokgak District, Buleleng, Bali. The objective was to determine the value and correlation of the C/N ratio with the total bacteria in the wastewater of vannamei shrimp aquaculture. Bacteria spread in the water column and sediment surface and exhibit faster population growth when the C/N ratio is optimal. The study was conducted from October to December 2024 using a descriptive quantitative research method, with purposive sampling from two stations in different vannamei shrimp aquaculture locations. Carbon, nitrogen, and total bacterial content were measured using the Walkley-Black method, Kjeldahl method, and Total Plate Count (TPC), respectively. The results showed average C/N ratios of 12.84 ± 4.10 at station one and 15.94 ± 9.43 at station two. The average total bacterial counts were 1.0 x 105 CFU/ml at station one and 3.2 x 104 CFU/ml at station two. The C/N ratio and total bacterial counts were within safe values for aquaculture wastewater, while correlation tests showed a negative relationship at both stations, with a strong correlation at station one and a weak correlation at station two.

Hubungan Panjang–Berat dan Morfometrik Gastropoda di Ekosistem Mangrove Pulau Tunda
type: item
description: Penelitian ini mengkaji variasi morfometrik serta hubungan panjang–berat dua spesies gastropoda, Terebralia sulcata dan Clypeomorus batillariaeformis, yang menghuni ekosistem mangrove Pulau Tunda. Pengambilan sampel dilakukan menggunakan metode transek kuadrat pada tiga arah pengamatan (utara, timur, dan selatan), menghasilkan 59 individu dengan dominasi Terebralia sulcata. Analisis morfometrik menggunakan Principal Component Analysis (PCA) menunjukkan bahwa transek selatan memiliki keragaman bentuk terbesar, terutama dipengaruhi oleh ukuran aperture, sedangkan variasi pada transek timur dan utara lebih ditentukan oleh dimensi cangkang. Analisis hubungan panjang–berat menggunakan model regresi allometrik menunjukkan korelasi positif pada kedua spesies, dengan nilai koefisien determinasi lebih tinggi pada Terebralia sulcata, yang menandakan konsistensi pertumbuhan yang lebih stabil dibandingkan Clypeomorus batillariaeformis. Hasil ini menegaskan adanya perbedaan pola pertumbuhan dan karakter morfometrik antarspesies, yang mencerminkan strategi biologis masing- masing dalam memanfaatkan ruang dan sumber daya di ekosistem mangrove. Secara keseluruhan, penelitian ini memberikan gambaran komprehensif mengenai variasi struktur tubuh serta hubungan dimensi morfometrik kedua spesies gastropoda, sehingga dapat menjadi dasar bagi kajian lanjutan terkait ekologi, pertumbuhan, maupun dinamika komunitas gastropoda di kawasan pesisir.

Analysis of Primary Productivity of Waters in Jakarta Bay
type: item
description: The Jakarta Bay is a coastal area that receives input from 13 major rivers and various anthropogenic activities, making it vulnerable to environmental degradation. This study aims to analyze the primary productivity of Jakarta Bay by identifying limiting factors from physical, chemical, and benthic aspects. This research uses a quantitative descriptive approach by utilizing secondary data from previous studies, monitoring reports, and official data from relevant agencies. The results show that high turbidity, fluctuations in temperature, salinity, and low dissolved oxygen are the main physical factors that limit light penetration and reduce photosynthesis efficiency. From a chemical perspective, excess nutrients such as nitrates and phosphates, along with heavy metal pollution, trigger eutrophication, phytoplankton blooms, and oxygen depletion. From a benthic aspect, the dominance of tolerant species, low diversity, and the presence of foraminifera with abnormal shells indicate ecosystem degradation in coastal and estuarine areas, while relatively stable conditions are found in the open sea. To maintain the sustainability of the ecosystem, integrated management is required through the control of nutrient loads, periodic monitoring of water quality, and the restoration of coastal ecosystems such as mangroves, seagrasses, and coral reefs. These efforts are expected to preserve ecological functions while also supporting the continuity of coastal community activities.

Diversity, Evenness, and Dominance of Coral Biota on the Eastern and Western Sides of Tarahan Island, Bojonegara District, Banten
type: item
description: Tarahan Island is a small island located in the northern part of Banten Province, Indonesia. Its proximity to the industrial zone near Bojonegara, Banten, makes it susceptible to pollution, leading to a decline in the diversity, evenness, and dominance of biota inhabiting dead coral reefs in the area. The objective of this study was to determine the diversity index, evenness index, and dominance index of biota on dead coral at Tarahan Island, Banten. The research focused on two sampling stations: the western and eastern sides of the island, using a random sampling method. The findings revealed both similarities and differences in species composition between the two stations. At the western station, 4 phyla comprising 24 species were identified, while the eastern station recorded 4 phyla with 21 species. The calculated diversity index (H') was 2.83 for the western station and 2.55 for the eastern station. The evenness index (J') was 0.90 (west) and 0.84 (east), while the dominance index (D) was higher at the eastern station (0.12) compared to the western station (0.08). By analyzing these indices in relation to the aquatic conditions of Tarahan Island, conclusions can be drawn regarding the ecological stability of the biota inhabiting the dead coral reefs.

Arthropod Diversity in Seagrass Ecosystems in the Eastern part of Tarahan Island, Serang Regency, Banten
type: item
description: Tarahan Island, Banten, has the potential for coastal ecosystem wealth, including seagrass beds and various other biodiversity. However, scientific information on the diversity of Arthropods and the condition of seagrass there is still minimal, so researchers conducted research on information on the diversity of Arthropods and the condition of seagrass on Tarahan Island. Through a purposive sampling technique considering the density and distribution of seagrass in the research area, the results of the study showed the presence of a dominant seagrass species Thalassia Hemprichii with a seagrass ecosystem health index (IKEL) score of 0.25 indicating very poor conditions due to low seagrass cover and density. The Shannon-Wiener arthropod diversity index (H') of 3.07 indicates high diversity with the dominance of the Gastropoda class (15 species). However, the uniformity index (E = 0.11) indicates non-uniform species diversity, compared to the dominance index (D) which justifies the dominance of Gastropoda over other classes.

Comparative Analysis of Crustacean Diversity in Dead Coral and the Eastern Coastal Area of Tarahan Island.
type: item
description: In this study, the species diversity of crustaceans in two different habitats on the eastern side of Tarahan Island—coastal and dead coral reef areas—will be compared, and their link to water quality will be investigated. Purposive sampling and handpicking methods were used for the sample process. Dissolved oxygen (DO) and biochemical oxygen demand (BOD) metrics were used to evaluate the quality of the water. According to the findings, there were more species and individuals in the coastal area than in the habitat of dead coral. A balanced community was indicated by the moderate Shannon-Wiener diversity index (H') in both locations (1.94 and 1.96) and the low dominance index (C) (0.1). Water quality met aquatic life standards. The structure of crustacean communities is influenced by variations in habitat features and environmental quality, which also act as ecological indicators.

The Effect of Habitat Differences on the Distribution of Mollusc Communities on the North Coast of Tarahan Island, Banten
type: item
description: This study examines the diversity of mollusks in Tarahan Island, Banten Bay, which has coastal ecosystems such as coral reefs, macro algae, and debris. Samples were taken from three stations using purposive sampling method. Data analysis included ANOSIM to test for differences in community structure across habitats and nMDS to visualize species distribution patterns. The findings showed that coral reef ecosystems had the highest species diversity, while rubble had the lowest variation. Species such as Turbo argyrostomus contributed significantly to community variation between habitats. The R value obtained from ANOSIM showed that the differences between habitats were not statistically significant, suggesting that environmental factors such as food availability and water quality have more influence on mollusc distribution than habitat substrate type. This study confirms that Tarahan Island is a significant area for representing mollusc diversity, especially in recognizing the distribution and variation of species in its coastal habitats..

Analysis of Coral Life Form Based on Oceanographic Parameters in Ayer Island, Thousand Islands
type: item
description: Coral reefs are aquatic ecosystems that play a crucial role in marine life. Coral reefs have a highly sensitive relationship with oceanographic parameters, which can influence the diversity of coral growth forms. The purpose of this study is to understand the relationship between lifeform diversity and oceanographic parameters in Pulau Ayer, Kepulauan Seribu. The Underwater Photo Transect (UPT) method was used for data collection, and the CPCe (Coral Point Count with Excel extensions) software was employed for data analysis based on observations. Principal Component Analysis (PCA) was used in data processing and in analyzing the relationship between growth form diversity and oceanographic parameters. The data analysis results show that the most abundant or dominant growth forms in Pulau Ayer waters are the branching form with the genus Acropora (ACB), the encrusting form with the genus Acropora (ACE), and the massive form (CM). The diversity of these growth forms is influenced by oceanographic parameters; for example, ACB can thrive in clear waters with weak currents, while CM can live in areas with strong currents and high turbidity.

Distribution and Characteristics of Marine Debris in the Coastal Area of The villages of Banyubiru, Baluk, and Cupel, Bali
type: item
description: Marine debris is a living environmental problem that is now a global issue that attracts everyone's attention as it threatens marine ecosystems. The shipment of garbage from the State district crossing the Kaliakah and Ijogading rivers contributed to the scale of the waste distribution on the coast. The study aims to analyze the concentrations (quantity and weight), characteristics (type, weight, size and shape) and distribution of garbage stranded in the coastal areas of Banyubiru Village, Baluk and Cupel. The waste data collection method adopts the method developed by the Commonwealth Scientific and Industrial Research Organization (CSIRO) Global Plastic Pollution Project by naming the transec line vertically to the coastline three times. Deposits in the coastal areas of Banyubiru Village, Baluk and Cupel are scattered across the area with concentration values of marine garbage ranging from 1.20 to 6.71 items/m2 with an average of 2.74 items/m2 and the resulting concentration of massive marine waste ranges from 13.50 to 93.05 grams/m2, with average of 49.416 grams/m2. Based on the amount of garbage it is classified by the soft plastic class 30%, while weight it is dominated by the wood class 23%. The total weight of all types of marine waste is 37.370 grams. The size of trash is 16-21 cm2 29%. 46% of the waste in the coastal area is whole and 54% is fragmented. In general, coastal marine debris is mostly consumer products. Therefore, public awareness plays an important role in reducing the amount of garbage in the region.

The chlorophyll-a parameter contributes the most to the distribution of flying fish (69.8%) with a permutation importance value of 58.5%, while sea surface temperature contributes 30.2% with a permutation importance value of 41.5%. The potential fishing areas are concentrated in the central part of the Arafura Sea, with 66.10% of the catch points located in the Habitat Suitability Index (HSI) zone of 0.5-0.8. Flying fish show a habitat preference in the optimal temperature range of 29-31°C with a presence probability reaching 0.8-0.9. Jackknife analysis confirms that the combination of sea surface temperature and chlorophyll-a parameters produces a more accurate predictive model compared to the use of individual parameters. This predictive model can be used as a reference to optimize flying fish capture activities efficiently and sustainably in the Fisheries Management Area (WPP) 718.

Analysis of Oceanographic Parameter Distribution of Tembang Fish Using ArcMap Case Study of the Arafura Sea
type: item
description: The Arafura Sea is a water area that is rich in biodiversity, including tembang fish (Selar spp.), which have high economic and ecological value. However, fishermen often face obstacles in determining optimal fishing locations due to the lack of oceanographic information. This research aims to analyze the distribution of oceanographic parameters such as sea surface temperature (SST) and chlorophyll-a concentration using MODIS satellite imagery and ArcMap software. SST and chlorophyll-a data were processed using the Inverse Distance Weighting (IDW) method to produce a distribution map of oceanographic parameters in the Arafura Sea. The results show that the optimal SST for tembang fish ranges from 26°C to 28°C, with high chlorophyll-a concentrations (0.8–1.2 mg/m³) found in coastal areas. The combination of these two parameters identifies promising Fishing Potential Zones (ZPPI). These findings provide benefits for fishermen in reducing operational time and costs, as well as supporting the sustainability of fisheries resources. This research emphasizes the importance of using oceanographic data and geospatial technology to improve fishing efficiency and marine resource management.

Analisis Arah dan Kecepatan Arus Laut Di Perairan Pulau Pelapis, Kabupaten Kayong Utara
type: item
description: This research aims to examine the speed and direction of currents in the waters of Peputar Village, Dusun Raya, Karimata Islands District. Current data collection is carried out through direct measurements using conventional current kites at several observation points. The measurement results show that the current speed at the surface ranges from 0.0138 to 0.4082 m/s, with the dominant direction towards the southwest and northeast, indicating the influence of the monsoon winds. These data indicate the existence of weak current stratification, as seen from the relatively stable current speed at various depths. The current pattern found is also consistent with the Wyrtki current model, which explains the current circulation in Indonesian waters which is influenced by monsoon winds. The results of this study can be used to understand water dynamics that impact local ecosystems and local fishing activities.

Analisis Pasang Surut Perairan Pulau Pelapis, Kabupaten Kayong Utara
type: item
description: Pelapis Island is one of the islands located in Dusun Raya, Pelapis Village, District. Karimata Islands, Kab. North Kayong, Prov. West Kalimantan. The pelapis island consists of several other small islands, both inhabited and uninhabited. Pelapis village is a village that has a variety of potential natural beauty and abundant natural resources that can be enjoyed. Tides are one of the oceanographic parameters that have a big influence on waters. Tides are fluctuations in sea level due to the gravitational force of objects in the sky, especially the sun and moon, on the mass of sea water on earth. This research aims to analyze the characteristics of tides in the waters of Pelapis Island, North Kayong Regency. Analysis was carried out using a tide staff 350 cm long for 3 days every 1 hour for 24 hours. The results of the analysis show that the tidal pattern in the waters of Pelayang Island has a semi-diurnal tidal type or high and low tides that occur twice a day. From the observations we made in the waters of the Pelaway Island Water Pier, the lowest tide was at around 20.00 WIB, namely 61 cm and continued to rise slowly so that the highest peak tide occurred at 07.00-09.00 WIB at a height of 265 cm. Then sea water will experience a continuous decline. Factors that influence tidal characteristics in this region, such as astronomy, include the position of the moon and sun, as well as local meteorological conditions. In addition, this research also identifies the impact of climate change on tidal patterns, which can affect the ecosystem and economic activities of local communities.
