dc.description.abstract | The increased human activity in the marine sector, such as dredging operations, oil and gas exploration, mineral sands mining
and various marine research has led to an imperative demand for accurate seafloor maps. Sub
-
bottom profilers (SBP) are acoustic
sy
stems traditionally used to image sediment layers and rocks beneath the seabed, providing information about sediment
thicknesses and stratigraphy. Therefore, the
objectives of this research were
to determine the profile of the seafloor sediment layer
(near
-
surface sediment) and obtain the value of the reflection coefficient of the layer. The process of data acquisition was conduc
ted
using SBP type of a single channel sparker by
BPPT that
was the
survey of oil and gas pipeline maintenance and electrical cable
Pertamina in 2010, which was on the east coast Balongan, Indramayu. Whereas for seafloor sediment sampling was used gravity
corer. The results of the processing of the raw data with Matlab nea
rby B19 have been obtained 2D profile of seabed sediments
and reflector, which was clearly visible and had a reflection coefficient value range 0 to 0.2955. In addition, an analytical
technique for parameter estimation of sediment from laboratory data was
performed as a comparison. The result of sediment in
the form of silt with reflection coefficient value was 0.2807 | id |
dc.description.abstract | Peningkatan aktivitas manusia di bidang kelautan sepert i operasi pengerukan ( dredging ), eksplorasi minyak dan gas, penambangan pasir mineral, dan berbagai penelitian kelautan telah mengakibatkan permintaan yang mendesak terhadap peta dasar laut yang akurat. Sub - bottom Profiler (SBP) adalah sistem akustik tradisional yang digunakan untuk menggambarkan lapisan sedimen dan batuan di bawah dasar laut , serta memberikan informasi tentang ketebalan sedimen dan stratigrafi nya . Oleh karena itu, tujuan dari penelitian ini yaitu menentukan prof il lapisan sedimen dasa r laut ( near - surface sediment ) dan memperoleh nilai koefisien refleksi dari lapisan tersebut. Proses akuisisi data dilakukan menggunakan SBP jenis sparker single channel oleh BPPT, yaitu survei pemeliharaan pipa migas dan kabel listrik Pertaminatahun 2010 ya ng berada di sebelah timur pantai Balongan, Indramayu. Pengambilan sampel sedimen dasar laut menggunakan gravity corer. Hasil dari pengolahan data mentah SBP dengan Matlab di dekat lokasi B19 diperoleh profil 2D dari lapisan sedimen dimana terlihat jelas d asar laut dan reflektornya serta memiliki nilai koefisien refleksi berkisar 0 hingga 0.2955. Selain itu teknik analitis untuk estimasi parameter sedimen dari data laboratorium ditunjukkan sebagai pembanding. Hasil sedimennya berupa silt/ lanau dengan nilai koefisien refleksinya adalah 0.2807. | id |
