Abstract. The diversity and heterogeneity of coastal, estuarine stream habitats has led to them becoming a prevalent topic for study. Woody ruins are areas potential riverbed habitat, particularly fish. Therefore, the mapping those is interest. However, due limited visibility in some river systems, satellites, airborne or other camera-based systems (passive systems) cannot be used. By contrast, sidescan sonar popular underwater acoustic imaging system that capable providing high- resolution...
Abstract The Indonesian government has initiated a program for Ina Tsunami Early Warning System by the development of sea level monitoring systems including Cable-Based Tsunameter. Seabed feature characterization is critical part engineering design process as well understanding environmental impacts. This study aims to characterize seabed morphology along cable route plan at Cilacap segment analyzing seafloor mapping and identifying any existing hazards. A series marine surveys data...
Abstract A new multibeam dataset of Nieuwerkerk and Emperor China (NEC) seamounts was acquired during the Jalacitra 2-2022 ”Banda” Expedition in Banda Sea region. This study discusses a morphometric analysis based on high-resolution bathymetry digital elevation model (DEM) describes features, namely: slope, profile curvature, aspect. Morphological results indicate that seamount has an area 2,416 km 2 with maximum peak approximately 3,460 m above seabed 357 below water surface. In southwest...
Abstract On 12 December 1992, an earthquake, followed by a tsunami, occurred on Flores Islands, creating massive damage in the northern area and resulting early warning tsunami for Labuan Bajo region. This is high-priority tourist designation Indonesia with busy offshore activities infrastructure development. Thus, earthquake mitigation strategies are mandatory. Part of effort mapping seafloor characterizing oceanographic conditions deep-water north this area. paper describes using multibeam...
Abstract In 2022, the Indonesian government initiated EWIN MeGaMal expedition (Ekspedisi Widya Nusantara Mekanisme Gempa Laut Maluku). The goal of is to map earthquake and tsunamigenic potential areas around Ambon Island. was carried out from 8 28 August 2022 using RV Baruna Jaya VIII. One methods used in multibeam echosounder (MBES) survey. To obtain an accurate bathymetry result, several stages need be out. Initially, a vessel reference frame (VRF) with defined point called common (CRP)...
Tsunami merupakan kejadian alam yang dipengaruhi oleh aktifitasyang terjadi di dasar laut seperti gempa laut, gunung berapimeletus, dantanah longsor laut. Indonesia berada pada kawasan “Pacific ring of fire” negara rawan akan bencana tsunami. Saat ini, BPPT telah mengembangkan beberapateknologi untuk mendeteksi tsunami, salah satunya dengan Cable Base Tsunamimeter (Ina-CBT). Teknologi ini dapat tsunami menggunakan sensor Ocean Bottom Unit (OBU) terpasang dan kemudian OBU mengirimkan sinyal...
Exploratory Analysis as one of the spatial analysis tools that has been used widely in many study fields. This tool is usually intended to obtain pattern observe and get relationship between variables. The exploratory followed by confirmatory exhibit hypothesis already analysis. aimed investigate prevalence asthma Western Australia since there are factors cause dispersion. Many provided variables have tested best correlation with percentage variable four (humidity, annual rainfall, EVI...
As an archipelagic country, the shipping sector in Indonesia becomes crucial delivering goods inter-island, and due to increasing transportation demands. However, that industry encounters some challenges of ocean environment could lead vessel accidents. An investigation into accident is since this related properties, environment, life disadvantages. The wrecks sinking vessels also harm providing obstacle sea passage hence risk a operation. A proper comprehensive needs be carried out identify...
Ina-CAT is an Indonesian Coastal Acoustic Tomography (CAT) system that applied to the Tsunami Early Warning System (TEWS). Also known as (TCAT), one of these systems was installed in Karangasem-Bali using a buoy platform. TCAT requires power for electronic and energy transmit acoustic signal through its transducer. The charging carried out by installing solar cell on surface buoy. Thus, monitoring needed observe process consumption. also observes temperature humidity so environmental...
Kepulauan Raja Ampat merupakan salah satu tujuan wisata utama di Indonesia dan juga sebagai kawasan konservasi alam. Hal tersebut disebabkan karena wilayah kaya akan keanekaragaman hayati, kenampakan sumber daya alam, serta budaya. Pada tahun 2014, pemerintah menyelenggarakan kegiatan Sail bagian promosi pembangunan tersebut. Badan Pengkajian Penerapan Teknologi (BPPT) berperan dalam dengan menggunakan KR Baruna Jaya IV untuk melakukan survei kelautan maupun diseminasi teknologi. Penelitian...
Hard bottom communities contribute significantly to the underwater marine-system. Thus, this has emphasized importance of hard-bottom delineation and mapping. In Indonesia, these ecosystems spread in entire country, specifically eastern waters Indonesia. Multibeam sonar survey is a proper technology map distribution. This technique can generate bathymetry Digital Elevation Model (DEM) backscatter imagery. study, texture analysis multibeam imagery Bathymetric Position Index (BPI) DEM are...
This study employs underwater acoustic remote sensing technology and deep-sea soil sampling to map characterize the seafloor in Flores Sea examine seamounts potential deposits. The Multibeam Echosounder (MBES) is utilized as an instrument provide high-resolution ocean bathymetry data, while gravity core collects sediment data deep sea. Considering geological bathymetric background of Sea, tectonic processes may have contributed seamount formation. Seamounts offer conditions conducive...
The application of multibeam echosounder for seabed topography has been developing rapidly. Multibeam is a very efficient way to get wide coverage each ping, so it can produce high-resolution maps. These maps be used as reference further investigation or exploration, example geological studies, marine habitats and others. RV Baruna Jaya IV operated by Laboratory Marine Survey Technology – BPPT that have hull mounted equipped Germany technology echosunder Seabeam 1050D system. allow sweep...
River and estuary areas commonly exhibit complex heterogeneous habitats. Thus, revealing the distribution of riverbed morphologies could promote area management habitats protection. Since remote sensing method manual survey are limited to use, side-scan sonar performs an expectant outcome in underwater habitat imaging. In shallow water stream areas, low-cost imaging has become a notable subject study, yet its use Indonesia is still limited. This study describes investigation...
Wilayah laut Indonesia bagian tengah dan timur merupakan perairan dalam dengan informasi batimetri yang masih terbatas. Data dapat diperoleh menggunakan alat survei khusus, yaitu Multibeam Echosounder (MBES). MBES pada Kapal Riset (KR) Baruna Jaya I mampu menghasilkan data hingga kedalaman 11 km. tersebut mempunyai dimensi fisik relatif besar, sehingga transducer harus dipasang secara permanen tunas kapal. Sistem terdiri dari beberapa sensor terintegrasi satu sistem akuisisi MBES. Agar...
