Abstract

Sunda Strait has an important role in the water mass exchange from the Pacific Ocean and the Indian Ocean so that the oceanographic condition is strongly affected by seasonal factors. The purpose of this study is to observe the relationship and the characteristics of significant wave height (SWH) and sea surface temperature (SST) in the Sunda strait and its relationship with IOD. The method employed is spatial analysis, low-pass filter, and spectrum analysis by S-Transform, beside that the correlation between SST and SWH is analyzed by wavelet coherency. The period of SWH and SST is dominantly semiannual, at the time of winter monsoon (the Northeast Monsoon), the SWH was reaching up to 2,11 m, while at the summer monsoon, the SWH was reaching up to 3.62 m. Reversely, the SST increased during the winter monsoon. At the time of 2016 had been detecting by the negative IOD with the IOD index of -0.65 and it caused the SWH increased by 0.3 m than its average. Based on the wavelet coherence, the SWH and the SST have the coherence in the period of 8 to 16 days, especially in March to April, and June to August.

Abstract

Tanjung Bemban is one of the seas found in the Nongsa sub-district, Batam city which is currently developed as a tourist attraction. This research aims to find out the hydro-oceanographic component, which consists of tide and the current and wave pattern in the sea of Tanjung Bemban Nongsa. To collect the data regarding tide, Tide Pole method, using measuring sign, is used, To collect data of sea current, Float Tracking (Lagrangian) method, by measuring distance and displacement of floating objects in the sea, is utilized, To collect the data of the wave, Wave Pole method, by measuring wave height, is employed. Based on the result of the research, it is clear that the tide of the sea is categorized as the semi diurnal, since there are two tides in one day with identical height, which occur sequentially and regularly. The highest flow reaches 260 cm and the lowest ebb 19 cm in the 4 days of observation, with 15 minutes interval. The measuring of ocean current is carried out for every 30-second intervals. Current velocity in Nongsa sea ranges from 0.02 m/s to 0.26 m/s. The current moves from east to southwest and west, even though some move northwest and north. Wave height is quite low, between 18 cm and 23 cm. Hydro-oceanographically, the Tanjung Bemban Nongsa area can be developed into a strategic tourism area

Abstract

This study aims to look at the conditions and characteristics of significant wave height and its relationship to wind velocity in the Makassar Strait in 2017. The data used in this study are bathymetry data from GEBCO with a resolution of 30 seconds, significant wave height data (Hs) with a resolution of 0.25 x 0.25 as well as wind velocity and direction with a resolution of 0.25 x 0.25 which are secondary data results from the European Center for Medium-Range Weather Forecasts (ECMWF) with a span of one year in 2017. The method used in this research is an analysis of the energy spectrum of significant wave height using Fast Fourier Transform. In addition, wind velocity and direction are processed by using GrADS software to see the visual conditions. Based on this study, it can be concluded that wind velocity is strongly associated with significant wave height values. This can be seen at each sample point in the Makassar Strait, where when the value of wind velocity is high, the value of significant wave height has the same conditions, and vice versa. The wind velocity value has a maximum value in the Makassar Strait during the east season with a value of more than 4.5 m/s. The highest energy spectrum occurs at point 3 in the Makassar Strait, which is 7303 m2 with a period of 6 months.

Abstract

This study aims to calculate the tsunami investment and the estimated arrival time at several locations around the Sunda strait, caused by the December 2018 Krakatao's eruption. The propagation of the tsunami wave is simulated using MIKE 21 Hydrodynamics Flexible Mesh (HD FM). The spatial data consist of the bathymetry and topography of the Sunda Strait area and its surroundings, whilst assumptions are made on the tsunami source topology and its exact location. Several runs of the simulation are then conducted by varying the Manning Number, i.e. bed resistance values, at the tsunami source and throughout the simulation domain, which accordingly would influence the propagation speed, inundation, and arrival time. Smaller Manning's values, which correspond to increasing roughness, are applied at locations closer to the tsunami source. In this simulation, Manning's number ranges from 10 to 40 m1/3s-1. Surface elevation, still water depth, and u and v velocity components are generated from this simulation.

Abstract

Fenomena lautan terkait dengan bidang kajian oseanografi dimana tiap parameter mempengaruhi satu sama lain, misalnya angin dengan gelombang. Kajian data angin penting diolah untuk meramalkan gelombang yang terbentuk. Pengolahannya pun harus diekstrak menggunakan ODV, selanjutnya ditentukan berdasarkan perhitungan rumus terkait. Angin berperan sebagai pembangkit gelombang. Angin yang bergerak terus-menerus, dalam durasi lama, kecepatan konstan, wilayah yang luas dan bertiup pada arah yang tetap mampu membangkitkan gelombang dengan ketinggian yang besar. Perairan Samudera Hindia tergolong besar dan 50% ukuran fraksi sedimen sebesar 0.13 mm. Perambatan energi gelombang yang besar mampu membawa sedimen yang besar. Laju transport sedimen dapat digunakan untuk menentukan perubahan garis pantai akibat sedimentasi maupun erosi/abrasi.

Abstract

NCICD is one of the national strategic programs to deal with coastal problems in Jakarta. One alternative structure to be built is WLP or known as coastal resort. As an initial step to make it happen, BAPPENAS plans to build a WLP pilot plan around the S. Cisadane estuary. One of the main considerations for designing the WLP layout is the process and pattern of sedimentation around the Cisadane estuary. Therefore, computational modeling of sediment transport around the Cisadane estuary was carried out for a period of 1 year (August 2020-July 2021). This modeling uses MIKE-21 module MIKE21/3 Integrated Models software which combines hydrodynamics and cohesive sediment transport models. Based on the results of this modeling, it is known that there are differences in sediment transport patterns in the west and east monsoons. During 1 year, changes in the thickness of the bottom sediment around the estuary of S. Cisadane ranged from -0.4 to 0.7 m with a mean of 0.086 m. Coastal reservoir design must take into the very dynamic sedimentation process around the Cisadane estuary.   Pengembangan Terpadu Pesisir Ibukota Negara (PTPIN) merupakan salah satu program strategis nasional untuk menangani permasalahan pesisir di Jakarta. Salah satu alternatif struktur yang akan dibangun adalah WLP atau dikenal sebagai coastal reservoir. Sebagai langkah awal mewujudkannya BAPPENAS merencanakan membangun pilot plan WLP di sekitar muara S. Cisadane. Salah satu pertimbangan utama untuk mendesain layout WLP adalah proses dan pola sedimentasi di sekitar muara Cisadane. Oleh karena itu dilakukan pemodelan komputasi transpor sedimen di sekitar muara Cisadane selama kurun waktu 1 tahun (Agustus 2020-Juli 2021). Pemodelan ini menggunakan software MIKE-21 module MIKE21/3 Integrated Models yang menggabungkan model hidrodinamika dan transpor sedimen kohesif. Berdasarkan hasil pemodelan ini diketahui bahwa terdapat perbedaan pola transpor sedimen di musim barat dan musim timur. Selama 1 tahun, perubahan ketebalan sedimen dasar di sekitar muara S. Cisadane berkisar -0,4-0,7 m dengan rerata 0,086 m. Pola sedimentasi yang sangat dinamis harus mendapatkan perhatian khusus dalam merancang waduk lepas pantai.

Abstract

The flight test of N219 Amphibious aircraft will be targeted in 2003/2024. For flight tests, these aircraft need a seaplane dock. One of the potential locations for the seaplane dock is Panjang Island at Seribu Islands. This study aims to know the characteristic of hydrodynamic and wave conditions and to determine whether Panjang Island is suitable for the seaplane dock. This study uses a modeling method with MIKE 21 FM HD-SW module and MIKE 21 Boussinesq Wave (BW) module. The bathymetry data were obtained from the Indonesian Navy Hydrographic and Oceanographic Center (Pushidrosal), tide data is generated from Tide Model Driver (TMD), wave and wind data from ECMWF. The result of surface elevation validation between hydrodynamic modeling and TMD is 92%. During the west monsoon and spring conditions, the difference in the largest and lowest current velocity is quite large (0.018-0.199 m/s), on the other hand, when the tides are in neap conditions (0.008-0.144 m/s). Meanwhile, during the east monsoon and spring conditions, the difference in the largest and lowest current velocities is quite large (0.02-0.193 m/s), on the other hand, when the tides are in neap conditions (0.008-0.146 m/s). The maximum wave height resulting from the 50-year return period waveform modeling between 1.139 - 1.474 m. Meanwhile, the significant wave heights between 0.679 - 0.741 with a significant wave period of 13.45 seconds. In general, the current and wave conditions of the two locations are suitable for the construction of the seaplane dock, except that the dominant wave heights are still above the requirements.

Abstract

Numerical modeling of hydrodynamics (HD) around the Tanjung Pasir Waters was carried out using MIKE 21 HD Flexible Mesh software to get the current velocity pattern conditions during the west and east monsoons. This activity is to support the NCICD sea wall construction plan. In addition, the results that will be obtained in this modeling are the conditions of the speed and direction of the current in various tidal conditions during spring and neap. The data used in this modeling include wind speed and direction, wave height, wave period, and wave direction. Based on the research that has been done, the validation value of Naotide tidal data on tidal field data is 93.8 %. HD MIKE 21 modeling results on field data have a validation value of 93.4 %. Extract points 4 and 5 which are the northernmost, have the highest current velocity values compared to the other points. In addition, when heading to the high tide phase, both spring and neap conditions, the current velocity value has the highest value.

Abstract

Muara Karang Power Plant (MKPP) is one of the main power plants on Java Island in Indonesia. Presently, the Jakarta provincial government has issued a reclamation project on Island G in the marine waters around MKPP. This reclamation effort is predicted to lead to a rise in the seawater temperature around the intake, which MKPP will address with the addition of intake channel of 250 - 957 m. Therefore, this study aimed to determine the effect of intake channel extension on the water temperature at the intake point using numerical modeling comprising hydrodynamics and dispersion advection modules. A total of 10 scenarios were modeled by varying intake channel length and season. The result showed that adding intake channel was less effective because the average water temperature was less than 0.24oC with an effectiveness below 0.78%. Based on the validation of the modeling results on the measurement data, the NRMSD values in west and east seasons were 9.13% and 12.63%, respectively. Under existing conditions, the average and maximum seawater temperatures were 31.40oC and 32.08oC. Meanwhile, by extending intake channel, the average and maximum water temperatures were 31.16oC and 31.60oC. These results showed that by extending intake channel, the temperature at the intake point was generally lower than the existing conditions. Intake channel length was more effective in reducing the temperature at the intake point during west monsoon than east monsoon. Vertically, the temperature at the bottom was relatively colder than near the surface. In west monsoon, the average temperature difference between the bottom and the surface ranged from 0.16-0.21oC, while in east, it was between 0.23 and 0.50oC. In conclusion, the addition of subsequent structures to increase effectiveness was necessary, specifically to hold hot water in east monsoon.
