Abstract

The reclaimed mangrove estuary in Muara Angke Kapuk is a reclaimed area that has not evaded the impacted of pollution and waste in the areas surrounding Cengkareng, Jakarta. This is apparent from the fact that almost all sediments under the mangrove trees are buried under heaps of plastic trash. However, the reclaimed region still has variety of organism, which indicating that the region still has an internal carrying capacity, especially nutrients from sediment. The purpose of this research was to examine the condition of sediment nutrients in this mangrove reclamation region. The research was conducted by taking water samples using a modification of the stratified cup at a sediment depth of 0-15 cm with depth intervals of 2.5 cm, and taking sediment samples using the sediment ring. Pore water samples were measured for dissolved oxygen (DO) and concentrations of ammonia, nitrite, nitrate, and phosphate. Sediment samples were used to obtain porosity values. The data obtained is used to make vertical concentration profiles and analysis of vertical nutrient flux. Vertical nutrient flux analysis was performed with the aid of QUAL2K software version 2.11. The results showed different vertical distributions and flux of nutrients, where influx for ammonia and phosphate and an increase in line with increasing sediment depth, while nitrate efflux and a decreased concentration. The flux calculation of nitrite as transitory nutrient was not done, but the concentration decreased after a depth of 2.5 cm. This indicates that the high contamination on the surface does not prevent the natural chemical processes so the reclaimed region can still provide nutritional support for its organism.

Abstract

Kondisi oseanografi dan pemilihan lokasi adalah faktor penting dalam keberhasilan dan keberlanjutan kegiatan budidaya lobster laut menggunakan sistem keramba jaring apung. Salah satu kendala budidaya lobster adalah belum adanya aturan khusus mengenai kriteria kesesuaian lokasi budidaya. Tujuan dari penelitian ini adalah untuk menentukan kriteria dan lokasi yang sesuai untuk budidaya lobster di sekitar perairan Teluk Pidada. Dasar kriteria yang digunakan adalah kesesuaian kondisi oseanografi dan kualitas air laut terhadap konstruksi keramba jaring apung dan habitat alamiah lobster. Metode analisis spasial menggunakan sistem informasi geografi dengan sistem pembobotan digunakan dalam penentuan lokasi yang sesuai untuk budidaya, yang mencakup kecerahan, kekeruhan, TSS, klorofil-a, DO, nitrat, fosfat, amonia, pH, TOM, dan salinitas. Hasil penelitian menunjukkan bahwa 9 dari 15 parameter memiliki kondisi yang sangat sesuai. Hasil studi analisis kesesuaian wilayah memperlihatkan bahwa 78,8% perairan atau seluas 2.890,8 ha dalam kategori sangat sesuai, kemudian hanya 21,2% perairan atau seluas 755,2 ha yang tergolong sesuai, dan tidak ditemukan kategori tidak sesuai di perairan Teluk Pidada. Hampir sebagian besar wilayah teluk sesuai untuk budidaya lobster, namun sebagian titik berlokasi agak menjauh dari daratan karena tingginya nutrien dan run-off kurang sesuai untuk kegiatan budidaya.

Abstract

Kendari Bay is coastal water in the center of the capital city of Southeast Sulawesi province. It is shaped like a pocket with a narrow mouth and there is an estuary of a large river, namely the Wanggu river, which makes the dynamics of its waters very interesting to study. The focus of the study is the hydrodynamic factors in the Kendari Bay and Wanggu River areas. This study aims to examine the hydrodynamic conditions of Kendari Bay, mainly due to the existence of reclamation and the influence of the Wanggu River which has not been studied previously. This research method uses a two-dimensional model based on bathymetric data, tides, and the flow of the Wanggu River with a simulation time of 15 days (1 March to 15 March 2020). The modeling results were then verified with PUSHIDROSAL tidal elevation data showing an RMSE value of 0.07 indicating that the model was well constructed. The mixed tidal type with a tendency to double daily is the tidal type of Kendari Bay waters based on the Formzahl number value of 0.51. The current pattern generally moves in and out from east to west and vice versa with a varying elevation range following spring conditions of 1.75 m. The maximum tidal speed is 0.1784 m/s and the minimum value is 0.0057 m/s which is shown in the sample results of the model when the hing to low tide, and low to high tide. The results of the hydrodynamic modeling show that the current velocity increases when passing through a narrow path, namely the bay estuary and river estuary. The existence of the reclamation area affects the changes in the velocity of the current which is significantly larger and the direction of the current that undergoes a deflection follows the shape of the reclamation area. The current direction is to the southeast and then turns towards the northeast when low to high tide and eastward then turns towards the northeast when the high to low tide spring conditions compared to research before the reclamation

Abstract

Lampung Bay is an important water crossing in South Sumatra that is greatly influence by anthropogenic activities and oceanographic characteristics. This study characterized and estimated the spatial and temporal Primary Productivity (PP) in the three sections of the bay: head, middle, and mouth. The PP was modeled by using Sea Surface Temperature (SST), chlorophyll-a, Primary Productivity, and Photosynthetically Active Radiation (PAR) collected from remote sensing data and field measurements. Primary productivity was modeled with a Vertically Generalized Production Model (VGPM), and data validation was done using the Root Mean Square Error method. The distribution of PAR in Lampung Bay ranged from 35–52.50 E/m2/day. The distribution of SST ranged from 28.5–31.50°C. The highest distribution of chlorophyll-a was at the hHead of the bay with a range of 0.30-12 mg/m3. Correlation analysis shows that chlorophyll-a had the highest influence on PP (R2=0.99). While the middle and outer areas of the bay have a low average with values of 122.65 and 101.84 gC/m2/year. Our models show that there is high primary production at the Head of the bay, reaching eutrophic and mesotrophic levels. The middle and outer areas of the bay show productivity levels corresponding to mesotrophic and oligotrophic levels.

Abstract

Deposisi sedimen di perairan sangat dipengaruhi oleh proses-proses pantai yang menyebabkan variasi karakteristik fisik dan kimiawinya. Penelitian ini mengungkap komposisi ukuran sedimen dan bahan organik di sedimen Teluk Lampung untuk menduga proses deposisi. Analisis fraksi sedimen dilakukan berdasarkan pada American Society for Testing and Materials (ASTM) standards D422-63, sedangkan bahan organik dilakukan dengan menggunakan metode loss on ignition (LOI). Fraksi pasir lanau (75,95-78,73%) dan fraksi lempung (18,27-20,28%) memiliki persentase yang lebih tinggi dibandingkan dengan fraksi pasir (3,00-3,81%). Kandungan organik di sedimen perairan Teluk Lampung berkisar antara 10,67-13,48%. Distribusi fraksi sedimen dan bahan organik di perairan Teluk Lampung tidak berbeda signifikan antar stasiun, yang artinya stasiun yang berada di dekat kepala teluk (TL 1 dan TL 2) memiliki persentase fraksi sedimen dan bahan organik yang tidak berbeda signifikan dengan stasiun yang berada di tengah atau ke arah mulut teluk (TL 3-TL5).

Abstract

Coasts or shorelines are sites of dynamic activity, and phenomena such as wave and tidal action, sediment supply rate, sea level changes, and the morphological characteristics of the area play a critical role in shaping coastal ecosystems. This study examines coastal changes along the Banyuasin Estuary in South Sumatra, Indonesia, over 30 years (1989–2019). We use remote sensing data, machine learning, and the DSAS tool to analyze historical changes (1989-2019). Landsat images obtained from the United States Geological Survey (USGS) via the Google Earth Engine API are analysed using ArcGIS and DSAS 6.0 software. The largest rate of change occurred at Anakan Island, with the most significant accretion rate being 118.98 m/year, causing a shoreline change of 2012.33 m over 30 years. The smallest shoreline changes were in the Telang and Payung Island areas, which are located in the Musi River Estuary. The magnitude of maximum shoreline change in both locations was 62.72 m and 92.34 m, respectively, with maximum rates of change ranging from 2.09 - 3.08 m/year. The results show that the general pattern of accretion-abrasion in the Banyuasin Estuary is divided into three stages: rapid accretion stage (1989-1994), accretion-erosion adjustment stage (1994-2009), and slow erosion stage (2009-2019).
