Abstract

One of the determining variables that influences coral growth morphology is the aquatic environment. Reef corals are unusual organisms with plant-like development patterns. Reef growth is influenced greatly by the aquatic environment, particularly hydro-oceanography. The same type of coral can have different morphological forms. This mismatch in form can lead to type identification mistakes. There is still a lack of research on morphological changes as an impact of coral plasticity in responding to environmental variables. The goal of this work is to compile a bibliography of coral morphological plasticity studies. Publish or Perish (PoP) program locates the Scopus database and processes the articles. After screening, 101 of the 138 articles found in the Scopus database are eligible to be found. Mendeley reference manager software is then used to handle the selected references. After maintaining the database, use VOSviewer software to classify and visualize the data. The findings suggest that the research topic was chosen based on keywords. Coral morphological plasticity research is primarily focused on the terms coral colonies and species. Small-scale coral morphology, morphological variability, and coral morphometrics are among the topics that have received little attention. The possibility of conducting research on the three subjects is still open. There are still many unanswered mysteries about coral. This work is crucial to research since it illustrates the direction of future plans for exposed coral morphology and plasticity. This review serves as a useful starting point for future coral morphology and plasticity research.

Abstract

The Tomini is one of the largest gulf in Indonesia. The gulf also has a unique profile and adjacent to Maluku Sea which is the eastern route of the Indonesian Throughflow. The purpose of this research is to investigate and analyze the circulation patterns that occur inside the gulf of Tomini and Maluku Sea as well as the variability of physical parameters such as temperature, salinity and transport volume and to correlate the driving factors of ocean-atmosphere phenomena that affect these physical parameters using the INDESO model dataset from January 2008 to December 2014 (7 years). The results showed that the surface circulation in the gulf and Maluku Sea flows southeastward to the Lifamatola Strait during the northwest and 1st transition, during the southeastern season the circulation flows leaving Maluku Sea through the ITF entry to the Pacific and Sulawesi Seas, and then flows southeastward during 2nd transition. The seawater temperature in the study area ranges between 28.6 - 32.0°C and the salinity varies between 32.2-34.4 psu. Vertical structure of zonal current in the gulf reveals velocity range from 0.02-0.3 Sv and the surface layer current is dominated by the westward flow, while at 20-60 m depth the flow is eastward. The mean transport volume at transects 123°E is about -0.028 (±0.2578) Sv. Variability of transport volume revealed spatial anomalies and periodicity on the intra-seasonal, semi-annual, annual, and inter-annual time-scales. Those are significantly coherence with zonal and meridional winds forcing in the Indo-Pacific region.

Abstract

Coastal areas are characterized by complex dynamics between freshwater entering through the estuary from land and seawater from open water. This study aims to calculate the salinity anomaly found on the sandy coast of Mayang, estimate the number of fractions and the volume of mass transport of fresh water entering the waters through the river flow and measure the total dissolved solids (TDS) in the west season. Water mass characteristics data collection using Water Checker. The determination of 17 data collection stations is assumed to be representative in representing the overall condition of the research location. The results of the anomaly salinity calculation show the low anomalous salinity values that are distributed horizontally on the coast. The distribution of salinity as anomaly values transversely on lines 1 to 4 ranges from -1 to -15. Freshwater fraction is concentrated as far as 1.16 km from the coast of Pasir Mayang with concentration values ranging from 0.44% to 0.13%. The mass transport of fresh water in the Pasir Mayang coastal waters is 1,130 m3s -1. The value of the transport volume of fresh water depends on rainfall and the flow of fresh water through rivers and then into sea waters. The total dissolved solids at the study site at each station ranged from 7.88 ppm to 17.8 ppm.

Abstract

The geomorphology of small islands in the eastern and western parts of Halmahera Island encompasses diversities of geological processes, island forms and types, and topography. The typology of the small islands to the west of Halmahera Island is volcanic and are categorized as hilly islands. To the east, there are coral islands classified as flat islands with smaller area contrast to volcanic ones. This study aims to analyze the land mass elevation of the small islands and the sub-bottom profiles in the eastern and western Halmahera waters. Island elevation data was obtained from Sentinel-2B imagery, whereas seafloor topographic data was acquired from direct field measurements using a GPS sounder. First, the image data underwent atmospheric, radiometric, and sunlight corrections, while the actual depth was estimated through bathymetry correction using tidal data. Then, QGIS version 3.16.6 and ArcGIS version 10.8 were used to analyze the data. The results show that the slope degree of volcanic islands is higher and their seafloor topography is steeper than that of coral islands. The slope degree of Ternate, Maitara, Tidore, and Hiri Islands, abbreviated as Termadoreh, is more than 30o with elevation of more than 100 meters, characterizing hilly islands. While there is only Pakal Island in Buli Bay that has a slope of 33o and the highest elevation of only 100 meters, it is nevertheless considered a flat island. Significantly, the different typologies indicate different morphogenesis and sub-bottom topography; i.e., volcanic islands have higher slope degrees and steeper seafloor profiles compared to coral islands.

Abstract

The waters of Jakarta Bay are one of the waters that are influenced by several fresh water flows that enter from the DKI Jakarta area and its surroundings. Sediment that enters the waters of Jakarta Bay is produced by the activities of the people who live in the Jakarta area and its surroundings. This study aims to analyze the sedimentation and distribution of suspended solids in the Jakarta Bay estuary using an observational approach and spatial analysis. This study uses the Inverse Distance Weighting (IDW) interpolation method. The dominant distribution of sediment in Jakarta Bay is sand with a size ranging from 0.25 to 0.125 mm. TSS (Total Suspended Solids) levels in 11 estuaries in Jakarta Bay ranged from 21 to 150 mg/L in first period and 11 ˗ 259 mg/L in second period. Sedimentation rates that occurred in 11 Jakarta Bay estuaries ranged from 11.12 g/cm2/day to 619.5 g/cm2/day in period one and 10.96 g/cm2/day to 1232.06 g/cm2/day in the second period which is located in Muara Cilincing in both periods. There is a suitable relationship between the TSS value and the sedimentation rate. Estuary TSS values and sedimentation rates are influenced by seasons and anthropogenic activities that occur in the estuary such as reclamation.

Abstract

Perairan Selat Bangka banyak mendapat pasokan air tawar dari sungai-sungai di pesisir timur Provinsi Sumatera Selatan, termasuk estuari Banyuasin.  Percampuran air tawar dan air laut menentukan kondisi lingkungan estuaria, khususnya pola salinitas, termasuk pembentukan habitat yang kompleks untuk komunitas tumbuhan dan hewan yang khas di dalamnya.  Tujuan penelitian ini adalah mengestimasi besarnya masukan air tawar dari empat muara sungai di estuari Banyuasin ke Perairan Selat Bangka pada bulan Oktober (musim peralihan II).  Pengukuran data lapangan dilakukan di 23 lokasi pada bulan Oktober 2018 menggunakan Valeport Midas CTD+ Model 606.  Selanjutnya, data salinitas digunakan untuk mengetahui kisaran nilai salinitas, menganalisis nilai anomali, fraksi air tawar dan stabilitas massa air dari masing-masing sungai.  Kisaran salinitas massa air di perairan Selat Bangka pada musim peralihan II adalah 2,19 sampai 31,42 psu dengan nilai anomali salinitas sebesar -30,23 sampai -1,00 psu. Masukan massa air tawar dari empat sungai adalah berbeda satu sama lain sehingga terbentuk kontur lidah salinitas di mulut estuari dan nilai salinitas bervariasi secara spasial di Selat Bangka.  Fraksi air tawar yang paling dominan berasal dari Sungai Musi dengan kontribusi sebesar 31,2 %, selanjutnya diikuti Sungai Air Saleh (21,9%), Sungai Banyuasin (20,5%) dan Sungai Upang (20,3%).

Abstract

Telah dilakukan penelitian tentang sebaran salinitas perairan laut Kabupaten Bengkayang pada musim kemarau. Penelitian ini dilakukan dengan melalukan pengambilan data salinitas, suhu dan konduktivitas massa air berdasarkan kedalaman di 23 stasiun pengukuran.  Lokasi penelitian berada pada koordinat 107,68 s.d 108,93 BT dan 0,69 LS s.d 0,87 LU. Lokasi penelitian terdiri atas lima lintasan yang membentang dari timur ke barat dan setiap lintasan terdiri atas empat stasiun pengamatan serta penambahan tiga stasiun pengukuran di sisi timur, barat dan selatan Pulau Lemukutan. Analisis dan visualisasi data massa air (suhu, salinitas, dan densitas) dilakukan dengan menggunakan perangkat lunak Ocean Data View (ODV) versi 4.7.6. Hasil analisis dan visualisasi data massa air menunjukkan bahwa salinitas massa air di perairan laut Kabupaten Bengkayang pada musim kemarau berada pada rentang 28,96 s.d 32,5 psu. Sebaran salinitas permukaan di daerah penelitian terbagi atas tiga bagian yaitu bagian utara, bagian tengah dan bagian selatan daerah penelitian, dengan tiap bagian membentang dari timur ke barat atau tegak lurus garis pantai. Massa air bersalinitas rendah (MABR) yang terjebak di bagian tengah diduga berasal dari massa air dari sungai yang terletak di bagian selatan pesisir Kalimantan yaitu Sungai Kapuas dan Sungai Mempawah. MABR tersebut terdorong dan bergerak ke arah utara sesuai dengan arah arus yang terjadi di pesisir Kalimantan Barat pada musim kemarau. Stratifikasi kolom air dalam kondisi stabil di seluruh daerah penelitian. Massa air yang bersalinitas kurang dari 30,5 psu ditemukan hingga kedalaman 4,5 meter di bagian barat daya, bagian selatan dan bagian tenggara Pulau Lemukutan. Massa air dengan salinitas 30,75 s.d 31,75 psu dapat dijumpai dari garis pantai hingga mencapai bagian barat Pulau Lemukutan dengan kedalaman sampai 10 meter dari permukaan.

Abstract. Mayalibit Bay has an unique topography due to it has only one way long canal , narrow, and devious that connecting to open sea. Study on the water mass dynamics concerning to elevation and tidal current in Mayalibit Bay was conducted by constructing the 2D numerical hydrodynamics model which was simulated for 30 days to describe the pattern of elevation and water current which was resulted from tidal processes. The 2D hydrodynamic equation was employed by finite difference methods. Validation result showed that the model has a good performance and it was relevance to in-situ measurement. The pattern of elevation and water current from many tide periods had been spatially analyzed. Generally, simulation showed that there was a significant difference between the elevation and water currents pattern inside and outside the bay during high and low tides.. Elevation and water current have higher value during highg tide (maximum 0.35 m and 0.2 m/s) than low tide period (maximum 0.14 m and 0.1 m/s ) with the velocity of water current was faster at ebb-tide or low tide. The water current in entry canal has higher value than in any part of the bay which themaximum velocity was varied from 1.6 m/s (flood-tide) to 3.7 m/s (ebb-tide). The direction of current during high tide flows was dominantly to the West-Northwest or enters the bay by following its geometric and to the East-Southeast or exits from the bay during the ebb-tidesKeywords :  Tidal; quasi-enclosed waters; numerical models; finite difference  Abstrak. Teluk memiliki topografi yang unik karena hanya memiliki satu celah atau jalur panjang, sempit, dan berkelok yang menghubungkannya dengan laut terbuka. Kajian dinamika massa air terkait elevasi dan arus pasang surut di Teluk Mayalibit telah dilakukan dengan membangun sebuah model numerik hidrodinamika 2D yang disimulasi selama 30 hari untuk menggambarkan pola elevasi dan arus akibat pasang surut. Persamaan hidrodinamika 2D diselesaikan dengan metode beda hingga. Hasil validasi menunjukkan bahwa model telah memiliki performa yang cukup baik dan relevan bila diverifikasi dengan hasil pengukuran di lapangan. Pola elevasi dan arus dalam beberapa periode pasang surut dianalisis secara spasial. Hasil simulasi menunjukkan bahwa ada perbedaan yang signifikan antara elevasi dan pola arus di dalam dan di luar teluk selama periode pasang purnama dan pasang perbani. Elevasi dan arus memiliki nilai yang lebih tinggi pada saat pasang purnama (maksimum 0,35 m dan 0,2 m/detik) dibandingkan dengan pada saat pasang perbani (maksimum 0,14 m dan 0,1 m/detik) dengan kecepatan arus yang lebih tinggi pada saat surut. Arus di jalur masuk teluk memiliki nilai yang lebih tinggi dibandingkan bagian manapun di dalam teluk, dimana kecepatan maksimumnya bisa mencapai 1,6 m/detik (pasang) sampai 3,7 m/detik (surut). Arah arus dominan di dalam teluk pada saat pasang adalah Barat - Barat Daya atau masuk ke dalam teluk mengikuti geometrinya dan ke Timur-Tenggara atau ke luar teluk pada saat surut.

Abstract

Blue swimming crab (BSC) is a fishery commodity with high economic value and great demand in domestic and foreign markets. P. pelagicus swimming crabs are commonly found in Indonesian sea waters, one of the largest contributors to the country's foreign exchange after shrimp and tuna. The high demand for blue crab resources will trigger an increase in fishing efforts. If this is done continuously, it is feared that it could endanger the population structure. Moreover, disrupting the sustainability of blue swimming crab resources in the waters, this study examines the morphometric distribution and growth pattern of P. pelagicus crabs based on environmental characteristics in Candi waters, Pamekasaan Regency. Census sampling was carried out using the census method; the census method was carried out by taking all crab samples caught by fishermen. The results obtained found 33 individual crabs, which were divided into three classes, namely small (<10 cm), medium (>10 cm), and large (>12 cm) size classes. Male crabs dominated the research locations with wider straps than female crabs. The analysis results show that the width-weight relationship's b values are 1.47 (males) and 2.00 (females). In addition, male and female crabs have a positive allometric growth pattern. Blue swimming crabs are often found in habitats with a substrate of dusty mud, high salinity and organic matter.

Abstract

Mangrove ecosystem in Semarang City has an important role for survival of the coastal area. This is due to the function of mangroves as a barrier to coastal erosion, wave barrier, carbon producer, as a habitat for biota in coastal areas, as well as improving water quality. However, as time goes by, mangroves condition in coastal of Semarang is decreasing every year and causing coastal disasters such as coastal erosion and tidal flooding which have identically occurred on the coast of Semarang. Mangrove ecosystem area in coastal of Semarang City in 2020 is 163,250 Ha. The aim of this study is to determine the density of mangroves ecosystem from 2013 to 2022 with Landsat 8 and Sentinel 2 satellites. The method used to classify and determine the density of mangroves ecosystem is NDVI or Normalized Difference Vegetation Index. The results of analysis show that the mangrove density in 2013 was 412.889 Ha, while in 2022 it was 142.562 Ha. The density of mangroves has decreased by around 270.327 Ha (65.5%), this is due to erosion, land conversion into pond areas, and recently the construction of the Semarang-Demak sea wall. Whereas Sentinel 2 satellite is better to use because it has better image quality, details, and accuracy to show objects on the earth's surface compared to Landsat 8.   Ekosistem mangrove di Kota Semarang memiliki peran yang penting bagi keberlangsungan hidup wilayah pesisir. Hal tersebut dikarenakan fungsi mangrove sebagai penahan erosi pantai, penahan gelombang, penghasil karbon, sebagai habitat bagi biota di wilayah pesisir, serta memperbaiki kualitas air. Namun seiring perkembangan zaman, kondisi mangrove di pesisir Semarang semakin tahun kian berkurang sehingga menimbulkan bencana pesisir seperti terjadinya erosi pantai dan banjir rob yang telah identik terjadi di pesisir Semarang.  Luas ekosistem mangrove di wilayah pesisir Kota Semarang pada tahun 2020 yaitu seluas 163,250 Ha. Tujuan dari penelitian ini yaitu untuk mengetahui kerapatan ekosistem mangrove dari tahun 2013 hingga 2022 dengan citra satelit Landsat 8 dan citra Sentinel 2. Metode yang digunakan untuk mengelaskan dan mengetahui kerapatan ekosistem mangrove adalah metode NDVI atau Normalized Difference Vegetation Index. Hasil analisa menunjukkan bahwa kerapatan mangrove pada tahun 2013 seluas 412,889 Ha, sedangkan pada tahun 2022 seluas 142,562 Ha. Kerapatan mangrove mengalami penurunan sekitar 270,327 Ha (65,5%), hal tersebut disebabkan karena adanya erosi, alih fungsi lahan menjadi area tambak, serta baru-baru ini yaitu adanya pembangunan tanggul laut Semarang-Demak. Sedangkan citra satelit Sentinel 2 merupakan citra yang lebih baik digunakan karena memiliki kualitas gambar yang lebih bagus, detail, dan akurat untuk menunjukkan obyek dipermukaan bumi dibandingkan dengan citra Landsat 8.
