Abstract

Seawater intrusion is a problem in coastal areas affecting groundwater quality. Seawater intrusion's impact is thought to have occurred on the coast of Latuhalat, which is indicated by groundwater that tastes brackish in community wells. Consequently, people must buy fresh water to meet their drinking water needs. In addition, seawater intrusion disrupts biodiversity in coastal areas. This study aims to examine the phenomenon of seawater intrusion on the coast of Latuhalat by analysing the conductivity level of groundwater and the area of the coastal area intruded by seawater during the tidal phase. The method used is interpolating physical and chemical parameters and analysing the bicarbonate-chloride ratio based on the Revelle Index. The measurement and analysis of tidal phase data using the interpolation method show that the tide phase increases the electrical conductivity and groundwater chloride values. Electrical conductivity values in the fourteen wells ranged from 446 μmhos/cm to 3236 μmhos/cm, while chloride concentrations ranged from 50 mg/L to 6631 mg/L. Analysis of the bicarbonate-chloride ratio obtained Revelle Index (RI) values ranging from 0.017 to 2.321, which indicates that seawater intrusion occurs from low to medium levels. In the coastal area along ± 5 km, it is known that the area of the intruded area in the relatively low to moderate category covers an area of 1.82 km2 (36.4%). The spatial distribution of electrical conductivity and chloride values which are pretty high are concentrated in Omputty Hamlet, where it is strongly suspected that seawater's movement into inland aquifers, which is caused by the geological structure of the Latuhalat area, is exacerbated by the intensity of excessive use of groundwater by the surrounding community. ABSTRAK Intrusi air laut merupakan salah satu permasalahan di wilayah pesisir yang mempengaruhi kualitas air tanah. Dampak intrusi air laut diduga terjadi di pesisir Latuhalat yang diindikasikan oleh air tanah yang terasa payau pada sumur masyarakat. Sebagai konsekuensinya, masyarakat harus membeli air tawar untuk memenuhi kebutuhan air minum. Selain itu, intrusi air laut mengganggu keanekaragaman hayati di wilayah pesisir. Penelitian ini bertujuan mengkaji fenomena intrusi air laut di pesisir Latuhalat melalui analisis tingkat konduktivitas air tanah dan luasan daerah pesisir yang terintrusi air laut selama fase pasang surut. Metode yang digunakan yaitu interpolasi parameter fisika dan kimia, serta analisis rasio klorida bikarbonat berdasarkan Revelle Index. Hasil pengukuran dan analisa data fase pasang surut air laut dengan metode interpolasi menunjukkan fase pasang air laut berpengaruh meningkatkan nilai daya hantar listrik (DHL) maupun klorida air tanah. Nilai DHL pada keempat belas sumur mulai dari 446 μmhos/cm hingga 3236 μmhos/cm, sedangkan konsentrasi klorida mulai dari 50 mg/L hingga 6631 mg/L. Analisis rasio klorida bikarbonat mendapatkan nilai Revelle Index (RI) mulai dari 0,017 hingga 2,321 yang menandakan bahwa intrusi air laut terjadi mulai dari tingkat rendah hingga menengah. Pada area pesisir sepanjang ± 5 km, diketahui luasan wilayah yang terintrusi dengan kategori agak rendah hingga sedang mencakup area seluas 1,82 km2 (36,4%). Distribusi spasial nilai DHL dan klorida yang cukup tinggi terkonsentrasi terdapat di Dusun Omputty, dimana kuat dugaan pergerakan air laut ke akuifer daratan yang disebabkan oleh struktur geologi daerah Latuhalat diperparah oleh intensitas penggunaan air tanah berlebih oleh masyarakat sekitar.

Abstract

Madden Julian Oscillation (MJO) based on its propagation through the maritime continent can be divided into two types, namely MJO-C (Crossing) and MJO-B (Blocked) as evidenced by the spatial diagram of Hovmöller OLR anomaly. This study aimed to determine the effect of MJO variations, namely MJO-C and MJO-B on sea surface temperature and rainfall in the Indonesian region in the period of 1998 to 2015. The data used in this study are reanalysis models including sea surface temperature and rainfall with composite events (one month before propagation, during propagation, and one month after propagation of MJO-C and MJO-B). The results show that when MJO-C and MJO-B are active, sea surface temperature and the amount of rainfall are increased, especially in equatorial Indonesia and the southern hemisphere. When compared, MJO-C has a more significant impact than MJO-B.Keywords: MJO, Sea Surface Temperature, Precipitation

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

Pembangunan wilayah yang pesat di Desa Wangel, Kabupaten Kepulauan Aru, menyebabkan peningkatan aktivitas penambangan galian C, terutama pasir laut, yang berdampak langsung pada perubahan garis pantai. Fenomena ini merupakan hasil dari interaksi antara proses alami seperti abrasi dan akresi dengan aktivitas manusia yang menghasilkan penurunan garis pantai. Melalui pendekatan fisika, artikel ini mengkaji proses-proses fisik yang terlibat, seperti energi gelombang laut yang menyebabkan erosi serta dampak mekanis penambangan terhadap lingkungan. Penelitian ini menggunakan metode Digital Shoreline Analysis System (DSAS) dan Net Shoreline Movement (NSM) untuk mengukur perubahan garis pantai antara tahun 2012 dan 2023. Hasil analisis menunjukkan bahwa abrasi lebih dominan daripada akresi, yang dipercepat oleh penambangan galian C. Studi ini diharapkan memberikan wawasan bagi pengelolaan sumber daya alam yang berkelanjutan.

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

Konsentrasi klorofil-a merupakan parameter yang dapat digunakan untuk pendugaan penyuburan perairan. Penelitian ini bertujuan mengkaji karakteristik konsentrasi klorofil-a secara temporal dan spasial di perairan Kepulauan Kei, pada periode Desember 2017 hingga November 2018. Data klorofil-a merupakan hasil perekaman Citra MODIS kemudian dianalisis pola sebaran dan dinamika yang terjadi di perairan. Fluktuasi konsentrasi klorofil-a secara umum menunjukkan pola musiman, sedangkan pola variabilitas konsentrasi klorofil-a antar musim memperlihatkan kandungan klorofil-a maksimum ditemukan pada musim timur sebesar 0,70 mg/m3, dan kandungan klorofil-a terendah terlihat pada musim barat sebesar 0,10 mg/m3. Variabilitas klorofil-a sangat dipengaruhi oleh curah hujan, angin, gelombang dan intensitas upwelling di perairan.

Abstract

The Banda Sea waters are open waters that have very complex dynamics and water characteristics. Those waters have a diverse underwater topography and are surrounded by many islands, both large and small. In addition, these waters are also strongly influenced by the ENSO phenomenon. The purpose of this study was to analyze the distribution pattern of chlorophyll A in marine waters during the La Nina period and the level of primary productivity. This study uses monthly chlorophyll-a data in 2010, from the MODIS AQUA satellite which is then processed using Surfer-12 software. The results showed that there was a pattern of variation in the distribution of chlorophyll-a in the Banda Sea during the El Nino and La Nina phenomena.

Abstract

Strait waters are influenced by tides, water masses and surrounding land. This study aims to analyze the spatial distribution of nutrients in the waters of the Haruku Strait, Central Maluku Regency, Maluku Province. The research method used is the survey method by taking water samples. Water samples were taken from 17 observation stations spread across the Haruku Strait at depths of 1 meter, 25 meters and 50 meters using the Niskin Bottle Water Sampler. Nitrate concentration analysis using the OPTIZEN Alfa equipment (Spectrophotometer UV-Vis) and the Brucine Sulfate method (SNI: 06-2480-1991) and phosphate concentration analysis using the Ammonium Molybdate method (APHA 10th ed. 5400-PD, 1998). The time of observation took place on July 23, 2022. The results showed that the average concentration of nitrate at a depth of 1 m was 1.146 ± 0.647 mg/L, a depth of 25 m was 1.148 ± 0.709 mg/L and a depth of 50 m was 1.136 ± 0.701 mg/L while the average concentration of phosphate at a depth of 1m was 0.051 ± 0.028 mg/L, a depth of 25 m was 0.053 ± 0.029 mg/L and at a depth of 50 m was 0.049 ± 0.020 mg/L. The waters of the Banda Sea, the Seram Strait and contributions from the rivers on the coast of Ambon Island play a role in the distribution of nutrients in the waters of the Haruku Strait.
