The use of Multibeam echosounder (MBES) equipment for seabed detection has been done by several researchers, which provided intensity values of each research object. However, artificial targets (such as shipwreck) was very dangerous object for ship navigation hence its very important to quantify it. This research was conducted in the Sunda Strait to detect the target of metal shipwreck. The Kongsberg EM 2040 MBES was used along with supporting equipment and SIS software as a data recorder. MBES acquisition results then processed using software CARIS. Display of the results were presented using the software CARIS and Surfer. The results of this study showed that the detection of the shipwreck with MBES Kongsberg EM 2040 is very clear with 3-dimensional shape of the shipwreck. The shipwreck backscattering intensity values have range from -3 to +6.99 dB.

ABSTRACTEchoes from two targets cannot be distinguished if two targets are located in the same range. This will cause an error in some analysis process such as analysis to estimate fish density. Therefore, a high quality of single echo detection (SED) is needed to minimalize the overlapping echo. The aim of this study is to estimate target strength and density of the fish / stock using different SED criteria using split beam echo sounder in Pari Island. Data processing used was Sonar5-pro software for SED measurement. Data processing stages were producing new SED-echogram and executing biomass analysis using Sv/TS Scaling method. SED criteria setting are SED-ori, SED-d, SED-f, and SED-m. Using different SED criteria in biomass analysis produces different target strength and density of fish. Number of single fish detection and fish size proportion in each SED criteria setting is different. Distribution of Target Strength (TS) is dominated by -70 dB to -61 dB, fish length 0,8-2,2 cm, and density 1.000-5.000 fish/ha. The suggested SED criteria are SED-f for a high accuracy measurement.Keywords: fish density, Pari Island, single echo detection, target strength, split beam echo sounder-------ABSTRAKGema dari dua target tidak dapat dipisahkan jika kedua target berada dalam jarak yang sama. Hal ini menyebabkan terjadinya kesalahan dalam proses pengolahan data seperti analisis untuk mengestimasi densitas atau stok ikan. Oleh karena itu diperlukan metode single echo detection (SED) dengan kualitas tinggi untuk mereduksi gema yang tumpang tindih. Tujuan penelitian ini adalah mengestimasi target strength dan densitas ikan menggunakan pengaturan kriteria SED yang berbeda. Data yang digunakan merupakan data split beam echosounder di perairan Pulau Pari pada bulan Juni 2014. Pengolahan data menggunakan perangkat lunak Sonar5-pro. Tahapannya terdiri dari pembuatan SED-echogram baru dan analisis biomassa menggunakan metode Sv/TS Scaling. Pengaturan kriteria SED yang digunakan adalah SED-ori, SED-d, SED-f, dan SED-m. Penggunaan pengaturan kriteria SED yang berbeda dalam analisis biomassa menghasilkan nilai target strength dan densitas ikan yang berbeda. Jumlah ikan tunggal yang terdeteksi dan proporsi ukuran ikan juga berbeda pada tiap pengaturan kriteria SED. Dominasi sebaran target strength adalah -70 dB sampai dengan -61 dB (small), ukuran panjang ikan 0,8-2,2 cm (small), dan densitas 1.000-5.000 fish/ha. Pengaturan kriteria SED yang disarankan adalah SED-f karena memiliki akurasi tinggi.Kata kunci: densitas ikan, Pulau Pari, single echo detection, target strength, split beam echo sounder

Acoustic method can be used to objectively solve various scientific purposes and management, especially in fisheries field. Banda Sea is a part of fisheries management area (FMA) 714 which is dominated by small pelagic fish according to 2010 Fisheries Statistics. The dominant pelagic fish in Banda is scad (DecapterusÂ spp.)Â which belongs to small pelagic fish and is commonly caught in Banda Sea. The objective of this research is to estimate small pelagic fish density through spatial and temporal distribution as informaion on fisheries resources in Banda Sea, especially the location and depthwhere scad is abundant and foundin the highest density. Acoustic survey was conducted on 3-18 February 2016. Spatially, density measurement showed that the small pelagic fish distribution in Banda Sea spreadedalong the track of data acquisition and had the highest density in theswimming depth of 5-20 m.Â Moreoverhigh density of scad was tended to be found near the slopes of the sea close to the mainland. Temporally,small pelagic fish tended to travel in groups at the day and disperse at night. Density of small pelagic fish distribution according to daily distribution is commonly found at night (06.00 p.m.-05.00 a.m. GMT+8) and dawn (05.00 a.m.-06.00 a.m. GMT+8).

RINGKASANSebagai negara kepulauan, Indonesia memiliki potensi sumberdaya ikan yang besar. Pentingnya informasi keberadaan ikan dan jumlah stok ikan menjadi agenda penting saat ini. Selama ini nelayan dan pelaku industri perikanan tangkap melakukan pencarian ikan berdasarkan pengalaman melaut. Hal ini juga sangat dikeluhkan dengan tingginya harga solar, satu hari berlayar bisa memerlukan biaya lebih dari Rp.100 juta dalam mencari ikan. Penggunaan teknologi satelit dapat membantu mengukur suhu permukaan laut dan kandungan klorofil di suatu perairan. Tetapi seringkali, lokasi daerah penangkapan ikan yang dideteksi oleh satelit sering tidak tepat. Kerapkali informasi dari satelit tidak dapat diberikan kepada pengusaha perikanan atau masyarakat nelayan secara langsung (online).Kata kunci : teknologi akustik bawah air, stok ikan, habitat ikan, keberadaan ikan, potensi ikan

Identification and estimation of seahorse population in the marine environment are difficult to obtain. Nowadays, the observations use visual techniques, biologic and statistics. Bio-statistics approach has some limitations, such as times consuming and low accuracy. An approach was required to provide more accurate information, comprehensive, and based on telemetry (underwater acoustic). Acoustic reflection is an important information to observe underwater objects that can be used for stock assessment and behavioral studies. This research is a preliminary observation and measurement of seahorse Target Strength (TS). The results show that there are differences in TS value of seahorse at the active and passive moving condition. The fluctuations of TS values in active conditions are higher than those in passive conditions. This study has also found that the average TS value of seahorse in active moving conditions is -54.49 dB (± 3 dB). It is greater than the mean TS value in passive moving conditions -59.64 dB (± 3 dB). The approach of immobile fish (the passive moving condition) on the seahorse is better to increase the correlation value between TS to size. The relationship between TS and the size of the seahorse are discussed in the results of this study

A preliminary research programme was carried out in order to study the acoustic wave reflection or target strength (TS) of tuna fish using a quantitative echo sounder (QES). The relationships between TS to fork length (FL) and swimbladder volume, for bigeye tuna (Thunnus obesus) and yellowfin tuna (T. albacares) are investigated. The TS of bigeye tuna was about 3 dB higher than yellowfin tuna when comparing species at the same size. The result can be correlated to the swimbladder volume differencebetween species. The relationship between TS and swimbladder volume was quantified for both species.Keywords: tuna fish, target strength, quantitative echo sounder
