Abstract

Dinamika Laut Arafura dipengaruhi oleh iklim yang terjadi seperti angin Monsun dan ENSO. Pengaruh iklim terhadap perairan, tentunya juga akan berdampak pada parameter oseanografi yang ada pada perairan tersebut seperti suhu dan salinitas. Tujuan penelitian ini adalah untuk mengkaji variasi angin, suhu dan salinitas permukaan saat fenomena Enso di Laut Arafura. Data suhu dan salinitas yang digunakan adalah data dari model Marine Copernicus, data angin dari ECMWF dan data indeks Enso bersumber dari NCEP. Pengolahan data menggunakan perangkat lunak ODV, Mcrosoft. Exel dan Panoply. Hasil penelitian menunjukkan bahwa kecepatan angin cenderung lebih tinggi saat periode El Nino, sedangkan periode La Nina angin lebih rendah. Variasi suhu selama periode La Nina tahun 2010/2011 cenderung lebih tinggi daripada periode Normal tahun 2013, sementara selama periode El Nino tahun 2015 suhu laut lebih rendah daripada periode Normal. Suhu maksimum selama ketiga periode 31.8 oC dan suhu minimum 23.6 oC, sebaliknya sebaran salinitas selama periode El Nino cenderung lebih tinggi daripada periode Normal, sedangkan periode La Nina memiliki salinitas lebih rendah daripada periode Normal. Salinitas maksimum selama ketiga periode 35.5 psu dan salinitas minimum 22.3 psu. Perubahan suhu dan salinitas diduga dipengaruhi oleh fenomena ENSO dan pengaruh angin Monsun yang memengaruhi sirkulasi massa air di Laut Arafura.

Abstract

Salah satu permasalahan di wilayah pesisir yaitu intrusi air laut yang mempengaruhi kualitas airtanah di daratan. Kondisi ini sementara terjadi di Negeri Latuhalat, dimana masyarakat harus membeli air tawar untuk memenuhi kebutuhan air minum sehari-hari karena air sumur payau yang oleh penduduk setempat disebut salobar. Penelitian ini bertujuan untuk menganalisis tingkat salinitas air tanah dan luasan intrusi air laut di kawasan pesisir Latuhalat. Metode yang digunakan yaitu interpolasi spasial parameter fisika dan kimia serta analisis rasio klorida bikarbonat menggunakan software ArcGIS. Hasil penelitian  menunjukan kondisi pasang surut mengontrol konduktivitas air tanah dan distribusi klorida, dimana nilai konduktivitas dan klorida meningkat seiring dengan meningkatnya elevasi permukaan (pasang banjir). Nilai konduktivitas yang disurvei pada 14 sumur berkisar antara 446 μmhos/cm hingga 3236 μmhos/cm, sedangkan kandungan klorida berkisar antara 50 mg/L hingga 6631 mg/L. Analisis rasio klorida bikarbonat yang ditentukan oleh nilai Revelle Index (RI) mulai dari 0,017 hingga 2,321 menunjukan bahwa intrusi air laut terjadi dari tingkat rendah hingga menengah. Di area pesisir sepanjang 5 km, luasan wilayah yang tidak terintrusi adalah 3,18 km2 (63,6%). Sebaliknya intrusi rendah hingga menengah mencakup area sekitar 1,82 km2 (36,4%). Selain distribusi spasial konduktivitas dan klorida, konsentrasi yang cukup tinggi hanya diamati di Dusun Omputty, diinterpretasikan  pergerakan air laut ke daratan diakibatkan pasang surut air laut memperburuk kualitas airtanah.   One of the problems in coastal areas is seawater intrusion affecting the quality of groundwater on land. This is temporarily happening in Latuhalat Villages, where people need to buy fresh water to occupy their daily drinking water needs because of the brackish well water where locals called it salobar. This study aims to analyze the level of groundwater salinity and the magnitude of seawater intrusion in the Latuhalat coastal area. The method used is an interpolation of physical and chemical parameters and analysis of the bicarbonate chloride ratio using ArcGIS software. The results show that the tidal condition controls the groundwater chloride and conductivity distribution whereby the value of chloride and conductivity increased with the increasing surface elevation (flood tides). The conductivity value surveyed in the 14 wells ranged from 446 μmhos/cm to 3236 μmhos/cm, while the chloride content ranged from 50 mg/L to 6631 mg/L. The analysis of the bicarbonate chloride ratio determined by Revelle Index (RI) values ranging from 0.017 to 2.321 indicated that the seawater intrusion occurred from a low to moderate level. Within the coastal zone with an area of about 5 km, the non-intruded area was 3.18 km2 (63.6%). In contrast, the low-moderate intrusion covers an area of approximately 1.82 km2 (36.4%). In addition to the spatial distribution of conductivity and chloride, sufficiently high concentrations were only observed in Omputty Village. This state was due to the movement of seawater into land evoked by tidal regimes worsening groundwater quality.

Abstract

The northern coastal area of eastern Seram is a region prone to flood disasters, especially those caused by sea level rise or tidal flooding. The coastal flood case that occurred on February 22, 2022, in the eastern Seram region resulted in significant losses. In order to reduce material losses and improve the accuracy of early warning systems for coastal floods, a more in-depth identification of coastal flooding in the area is necessary. This study integrated the DELFT3D model with flood mapping using change detection and threshold methods to obtain the characteristics of tidal fluctuations and flood distribution in the case study on February 22, 2022. Water level observation data from the National Geospatial Information Agency (BIG) were used to validate the model results. The analysis showed that the DELFT3D model had a high correlation with the BIG observation data, with a correlation value of 0.98 and an RMSE value of 0.11. The flood-prone areas were found to be distributed along the eastern Seram coastline. The DELFT3D model also successfully predicted the water level during coastal floods with adequate accuracy. These results can be used to develop disaster mitigation strategies and improve the accuracy of early warning systems for coastal floods in the eastern Seram region. ABSTRAK Wilayah pesisir utara Seram Bagian Timur merupakan wilayah yang rawan terjadi bencana banjir yang diakibatkan adanya kenaikan muka air laut atau ROB. Kasus banjir pesisir yang terjadi pada tanggal 22 Februari 2022 di wilayah Seram Bagian Timur telah menimbulkan kerugian yang signifikan. Dalam rangka mengurangi kerugian materi dan meningkatkan akurasi peringatan dini banjir pesisir, perlu dilakukan identifikasi yang lebih mendalam terkait terjadinya banjir pesisir di wilayah tersebut. Dalam penelitian ini, dilakukan integrasi antara model DELFT3D dan pemetaan wilayah banjir menggunakan metode deteksi perubahan (change detection) dan ambang batas (threshold) untuk mendapatkan karakteristik pasang surut dan sebaran banjir pada studi kasus tanggal 22 Februari 2022. Data pengamatan water level dari Badan Informasi Geospasial (BIG) digunakan untuk memvalidasi hasil model. Hasil analisis menunjukkan bahwa model DELFT3D memiliki korelasi yang tinggi dengan data pengamatan BIG, dengan nilai korelasi sebesar 0,98 dan nilai RMSE sebesar 0,11 serta wilayah terjadinya banjir menyebar sepanjang pesisir Seram Bagian Timur. Pemodelan DELFT3D juga berhasil memprediksi tinggi muka air selama banjir pesisir dengan akurasi yang memadai.

Abstract

The Maluku Province region has the potential and is prone to high threats of natural disasters. The condition of the area consisting of small islands requires the community to have knowledge of coastal and marine disaster mitigation, so that it will increase awareness and minimize the impact when a disaster occurs. There are several stages in the implementation of PKM, including initial survey, coordination, problem identification, PKM implementation and counseling. Through this PKM, it has increased the understanding of the public (Angkasa high school students) to be more alert and alert to the potential vulnerability of coastal and marine disasters which can occur at any time

Abstract

Participatory mapping techniques are a way to facilitate the rapid collection of data and information at the community level. The Aru Islands, which have a considerable coastal resource potential, need to be supported by rapid data collection in support of sustainable management of coastal areas. Strengthening the local community in Aru is very much needed in terms of gathering such data through participatory mapping. The purpose of this participatory mapping is to identify the potential and utilization of space. In accordance with the entire phase of the process, a map of the fish species is produced which are potentially captured; the crustaceans which have economic value, the river streams of mega species and the locations which are the green turtle breeding areas, as well as three types of space utilization.

Abstract

This study investigated the characteristics of stratification and vertical stability of southern waters of Tanimbar Islands Regency. CTD Data from World Ocean Database 2018 especially November 1995 to represent second transitional season were utilized in this study. The CTD data were processed using Ocean Data View. This study showed that vertically the temperature of the surface layer ranged between 29 to 30 oC and the thickness of surface mixed layer was found to be 44 m. The thermocline layer has temperature ranging between 12 to 28 oC and a maximum depth of 306 m. Below thermocline layer temperature reduced to reach less than 7 oC (depth > 500 m). On the halocline layer, a high saline water was found between 66 - 94 m depth and was located on the southern part between Barbar Islands and Tanimbar Islands. Water mass was found to be unstable in the mixing layer.

Abstract

The Deep chlorophyll maximum (DCM) in the Banda Sea during the second transitional season (October 2015) was relatively shallow (25 - 64 m) above the mixed layer and far from the base of the euphotic layer or compensation depth. Its presence was identical to the depth of nitraclin injected into the mixed layer as a result of upwelling generated by internal waves. The contribution of these waves to the increase in Banda Sea fertility calculated using ocean color data is 56.87%. This phenomenon is due to the shallow optical depth of the satellite (20-25 m) while high chlorophyll-a concentrations are below. DCM was also associated with the swimming layer of Madidihang (Thunnus albacares) (34 - 68 m) caught with longline gear during the same period.

Abstract

The waters of Ambon Rumahtiga and Galala-Hative Kecil are part of the waters of Ambon Bay which connects Outer Ambon Bay (TAL) and Inner Ambon Bay (TAD). The characteristics of the waters are influenced by the tides and the input of fresh water which flows into the surrounding waters. This research aims to analyze front events both horizontally and vertically based on the distribution of temperature, salinity and water density. The research was conducted in August 2023 at 9 observation stations. Temperature, salinity and density measurements were carried out in-situ using a CTD (CTD type), and analysis of the vertical and horizontal distribution of temperature, salinity and density using ODV software version 5.6.2 and Surfer 12. Front analysis used a quantitative discrete method approach by comparing differences in temperature, salinity and density characteristics. The research results show that a front is formed on the water surface to a depth of 5 m between the water mass moving from TAD (Station 8) with a temperature of 26.16-26.58 oC, salinity of 30.98-33.37 Psu and sigma-t of 19.92 -21.64 Kg/m3 and water mass from TAL (Station 5) with a characteristic temperature of 25.97 oC, salinity of 33.03-34.22 Psu and sigma-t of 21.47-22.47 Kg/m3. Front events also occur between water masses with temperature characteristics of 26.17-26.32 oC, salinity 34.12-34.32 Psu, sigma-t 21.66-22.30 Kg/m3 (Station 6) with water masses with temperature characteristics 26.43-26.41oC, salinity 33.37-34.22 Psu and sigma-t 21.66-22.42 Kg/m3 (Station 9). Tidal currents and freshwater input that flows from the Wairuhu River are the causes of fronts.

Abstract

Upwelling is the rise of water mass in the lower layer to the surface. The rise of water mass is due to wind moving above the waters so that this wind will push the water mass on the surface as a result of which water from below replaces the emptiness above. The variation in SST distribution is relatively lower and the abundance of chlorophyll as an indicator of the occurrence of the upwelling phenomenon and the effect of wind on the upwelling phenomenon. The purpose of this study was to determine the variability of SST and chlorophyll in the waters of South Buru Island to Seram Island and its effect on the upwelling phenomenon. The method used is a quantitative method with the aim of describing the state of SST and Chlorophyll in the Waters of South Buru Island to Seram Island. The results of the study showed that the analysis of the distribution of SST and chlorophyll from June to October was an upwelling phenomenon with SST in June 28.15 ° C and chlorophyll-a 0.44 mg / m3 with an average wind speed of 4.58 m / s which was the beginning of the upwelling phenomenon. For July, the SST distribution was 27.21°C and chlorophyll-a 0.54 mg/m3 with an average wind speed of 5.42 m/s. In August, the SST distribution was 26.95°C and chlorophyll-a 0.58 mg/m3 with an average wind speed of 5.32 m/s. In September, the SST distribution was 27.73°C and chlorophyll-a 0.50 mg/m3 with an average wind speed of 4.09 m/s, while in October, the distribution was 28.97°C and chlorophyll-a 0.29 mg/m3 with an average wind speed of 2.65 m/s.
