Abstract

Marine environmental damage is one of the problems that has not yet been properly resolved to this day. Dumping waste into the sea is a global issue that the government continues to address by urging the public to preserve the marine environment in order to safeguard nature for the future. This Community Service (PkM) activity is carried out with the aim of fostering a sense of love and care for the marine environment from an early age, so that students are expected to continuously maintain and preserve the marine environment. The PkM activity was held on Wednesday, September 10, 2025, targeting 20 students from grades 1 and 2. The methods carried out in this Community Service Program (PkM) include an initial survey, coordination, preparation of materials, and outreach and implementation. The material was delivered for 60 minutes, followed by a question-and-answer session. During the outreach, the enthusiasm of the students was very high, indicated by the critical questions posed by the students, and the questions asked by the team could be answered well.

Abstract

This research was conducted to examine the seasonal variations in the Banda Sea's thermocline layer and its water mass characteristics. The research was conducted by analyzing Argo Float data. The data consists of six observation stations in West Season and Transitional Season II, and four stations in Transition Season I and East Season The thermocline layer thickness was identified based on the depth where the temperature decreased ≥ 0.05oC/m. The thermocline layer's distribution of depth and thickness and the distribution of temperature and salinity seasonally in the thermocline layer were analyzed with Microsoft Excel 2010. The analysis results showed that East Season and Transition Season II have a shallower upper boundary depth of the thermocline layer, a deeper lower boundary of the thermocline layer, and the thermocline layer is thicker when compared to the West Season and Transition Season I. The average temperature distribution is higher and the average salinity is lower in the West Season and Transition Season I. The mean rate of change in salinity and temperature in the thermocline layer seasonally ranged from 0.002-0.004 PSU/m and 0.06-0.08oC/m. The thermocline layer's stratification is stronger in the West Season and Transition Season I.

Abstract

Sea surface temperature (SST) plays a key role in modulating tropical convection, yet its influence on the vertical structure of convective clouds in island-based, anti-monsoonal regions remains poorly quantified. This study examines the relationship between SST variability and convective cloud characteristics over the coastal waters of Ambon Island during 2023. Daily SST data were obtained from ERA5 reanalysis, while convective parameters Convective Condensation Level (CCL) and Equilibrium Level (EL) were derived from twice-daily radiosonde observations. Owing to non-normal distributions and serial autocorrelation, Spearman rank correlation was applied with effective sample size (ESS) correction and bootstrap confidence intervals. Results show that SST exhibits a pronounced seasonal cycle primarily governed by monsoonal forcing. SST displays a moderate positive correlation with CCL (ρ = 0.532-0.580) and a consistently strong correlation with EL across all stations (ρ = 0.770-0.778; p_adj < 0.001), indicating a stronger SST control on convective depth than on cloud-base height. Although large-scale climate modes (ENSO, IOD, and MJO) contribute to short-term variability, seasonal monsoonal forcing remains the dominant modulator of SST-convection coupling. These findings represent robust statistical associations and highlight the importance of ocean-atmosphere coupling in regulating convective cloud structure in tropical maritime island environments.

Abstract

The Banda Sea serves as Indonesia's central region of water mass circulation and receives water flows from the Pacific Ocean, Indian Ocean, and South China Sea. This unique position facilitates significant interactions between the atmosphere and the ocean. This study aims to assess the dynamic factors supporting tropical cyclone Lili's growth in the Banda Sea. This study uses data from the Climate Data Store (CDS) and Marine Copernicus for May 4-12, 2019. The results show atmospheric dynamics, including the presence of low-pressure zones, high air humidity, and other meteorological factors that support the formation and movement of cyclones. During the study period, oceanographic conditions showed varying wind directions from various sources, hindering the wave formation process. Current patterns were observed moving from Australia through Tanimbar waters towards the Banda, Seram, and Timor Seas. In addition, eddy formation was found in Wetar waters, with downwelling processes occurring in the Banda Sea, while upwelling was detected in eastern Seram waters.

Abstract

The eastern Seram waters are influenced by both the Seram Sea and the Banda Sea. This study aimed to examine variations in wind, surface currents, and sea surface temperature (SST) during 2015, coinciding with the super El Niño event. Data were obtained from the Group for High Resolution Sea Surface Temperature (GHRSST) and the Copernicus Marine Environment Monitoring Service (CMEMS). The results indicated that the monthly average wind speed in this area ranged from 0.01 to 8.98 m/s, with the lowest speed in November and the highest from January and June to September. Surface currents also exhibited seasonal variability, flowing from the Seram Sea to the Banda Sea during the west season (December–January) and reversing eastward in February. During the east season, Banda Sea water masses were supplied by Seram Sea water. Sea surface temperature decreased notably from June to August, with the lowest temperature recorded in August due to upwelling in the Banda and Arafura Seas. Surface currents formed eddies with warm water centers in the northern part of eastern Seram waters, and cold water centers (25,4 °C) were also observed. The convergence of these two water masses with distinct characteristics generated thermal fronts with temperature differences, resulting in strong temperature gradients from August to October as a consequence of upwelling and cooling induced by the intense El Niño at the end of 2015.

Abstract

The Kei Islands water area is quite productive in fisheries management. Environmental characteristics and oceanographic factors in a body of water will determine the potential of fisheries resources in a water body, and influence fish movement patterns and the formation of fishing areas for flying fish eggs. This research aims to examine the distribution of sea surface temperature and chlorophyll-a concentrations and analyze the relationship between sea surface temperature and chlorophyll-a concentrations with catches of flying fish eggs. The research focused on the waters of the Kei Islands, Southeast Maluku, which is an area for catching flying fish eggs. The research data was studied in the period December 2014 – November 2017. SPL and Chlorophyll-a data were downloaded from Citra MODIS-Aqua, while data on flying fish egg production was obtained from PPN Tual. The research results show that the monthly average SST distribution is between 25.03-30.42ºC, and the monthly average of chlorophyll-a varies quite widely with a range of 0.05-3.09 mg/m3. The number of flying fish egg production fluctuates every year with a production range of 36.28-81.905 kg. The peak of catching flying fish eggs occurs in June-September (eastern season and transition season II). The results of the analysis show that the correlation between SST and chlorophyll-a variables has a very dominant influence on the abundance of flying fish eggs.

Abstract

The hydrodynamic conditions of the Maluku waters are highly dynamic and are generally influenced by several oceanographic factors, including current patterns that are also affected by variations in monsoonal winds. At present, global climate change associated with the El Niño–Southern Oscillation (ENSO) phenomenon is suspected to have altered wind and current patterns. This study aims to examine the variations in monsoonal wind patterns and monsoonal current patterns during ENSO events in the Maluku waters, including the Seram Sea, Banda Sea, and Arafura Sea. Monthly averaged wind and current data were obtained from the Copernicus database, while ENSO index data were acquired from the National Oceanic and Atmospheric Administration (NOAA) database. The results indicate that the average maximum wind speed during the West Monsoon reaches 6.1 m/s with a southeastward direction, whereas during the East Monsoon it reaches 9.2 m/s with a northwestward direction. Based on the direction of movement, the prevailing winds are characterized as monsoonal winds. The average maximum current velocity during the West Monsoon reaches 0.8 m/s with an eastward direction, while during the East Monsoon it reaches 1.4 m/s with a dominant westward movement. The dominant direction of current movement generally follows the direction of the monsoonal winds. The influence of ENSO indicates that the average wind speed and spatial distribution of winds increase during El Niño events, whereas the average current velocity and spatial distribution of currents increase during La Niña events.
