Abstract

Abstract. Mayalibit Bay has an unique topography due to it has only one way long canal , narrow, and devious that connecting to open sea. Study on the water mass dynamics concerning to elevation and tidal current in Mayalibit Bay was conducted by constructing the 2D numerical hydrodynamics model which was simulated for 30 days to describe the pattern of elevation and water current which was resulted from tidal processes. The 2D hydrodynamic equation was employed by finite difference methods. Validation result showed that the model has a good performance and it was relevance to in-situ measurement. The pattern of elevation and water current from many tide periods had been spatially analyzed. Generally, simulation showed that there was a significant difference between the elevation and water currents pattern inside and outside the bay during high and low tides.. Elevation and water current have higher value during highg tide (maximum 0.35 m and 0.2 m/s) than low tide period (maximum 0.14 m and 0.1 m/s ) with the velocity of water current was faster at ebb-tide or low tide. The water current in entry canal has higher value than in any part of the bay which themaximum velocity was varied from 1.6 m/s (flood-tide) to 3.7 m/s (ebb-tide). The direction of current during high tide flows was dominantly to the West-Northwest or enters the bay by following its geometric and to the East-Southeast or exits from the bay during the ebb-tidesKeywords :  Tidal; quasi-enclosed waters; numerical models; finite difference  Abstrak. Teluk memiliki topografi yang unik karena hanya memiliki satu celah atau jalur panjang, sempit, dan berkelok yang menghubungkannya dengan laut terbuka. Kajian dinamika massa air terkait elevasi dan arus pasang surut di Teluk Mayalibit telah dilakukan dengan membangun sebuah model numerik hidrodinamika 2D yang disimulasi selama 30 hari untuk menggambarkan pola elevasi dan arus akibat pasang surut. Persamaan hidrodinamika 2D diselesaikan dengan metode beda hingga. Hasil validasi menunjukkan bahwa model telah memiliki performa yang cukup baik dan relevan bila diverifikasi dengan hasil pengukuran di lapangan. Pola elevasi dan arus dalam beberapa periode pasang surut dianalisis secara spasial. Hasil simulasi menunjukkan bahwa ada perbedaan yang signifikan antara elevasi dan pola arus di dalam dan di luar teluk selama periode pasang purnama dan pasang perbani. Elevasi dan arus memiliki nilai yang lebih tinggi pada saat pasang purnama (maksimum 0,35 m dan 0,2 m/detik) dibandingkan dengan pada saat pasang perbani (maksimum 0,14 m dan 0,1 m/detik) dengan kecepatan arus yang lebih tinggi pada saat surut. Arus di jalur masuk teluk memiliki nilai yang lebih tinggi dibandingkan bagian manapun di dalam teluk, dimana kecepatan maksimumnya bisa mencapai 1,6 m/detik (pasang) sampai 3,7 m/detik (surut). Arah arus dominan di dalam teluk pada saat pasang adalah Barat - Barat Daya atau masuk ke dalam teluk mengikuti geometrinya dan ke Timur-Tenggara atau ke luar teluk pada saat surut.

Abstract

Abstract. The objective of the present study was to evaluate the possibility of jaloh leaf powders as alternative raw material for the formulated diet ofAfrican catfish (Clarias gariepinus). Four concentrations of jaloh leaf powders (0%, 5%, 10% and 15%) were examined in this study. The experimental fish were fed three times a day (on 08.00 am, 12.00 am and 17.00 pm) with feeding ration of 5% of body weight and the fish was reared for 35 days. The ANOVA test showed that the different concentration of jaloh leaf powders gave a significantly effect on growth performance of African catfish larvae (P0,05) but did not give significantly effect on the survival rate (P0,05). The Duncans test showed that the higher survival rate and growth performance were found in the control (without jaloh leaf powders). Therefore it is concluded that the jaloh leaf powders is not suitable as alternativerows material for African catfish diet.Key words: Protein; Carbohydrate; Catfish; Alternative feed Abstrak. Penelitian ini bertujuan untuk mengevaluasi kemungkinan pemanfaatan  tepung daun jaloh (S. tetrasperma) sebagai bahan baku alternatif untuk pakan ikan lele(C. gariepinus). Dalam penelitian ini telah diuji beberapa tingkat proporsi tepung daun jaloh yaitu (0%, 5%, 10%, dan 15%) .Pemberian pakan dilakukan tiga kali sehari, yaitu pada pukul 08.00, 12.00 dan 17.00 WIB,sebanyak5%dari berat bobot tubuhnyaselama 35 hari. Hasil uji ANOVA menunjukkan bahwa pemberian tepung daun jaloh memberikan pengaruh nyata (P0,05) terhadap pertumbuhan mutlak dan pertumbuhan harian benih ikan lele dumbo (P0,05), namun tidak berpengaruh nyata terhadap kelangsungan hidup (P0,05). Uji lanjut Duncan’s  menunjukkan bahwa perlakuan kontrol (tanpa daun jaloh) dalam pakan memberikan hasil terbaik dari segi pertumbuhan mutlak, pertumbuhan harian dan kelangsungan hidup. Oleh karena itu dapat disimpulkan tepung daun jaloh kurang sesuai sebagai bahan baku alternatif dalam pakan ikan lele dumbo.Kata kunci: Protein; Karbohidrat; Ikan lele; Pakan alternatif

Abstract

Abstract. Lombok Strait is one part of Indonesia Through Flow (ITF), important for national and international maritime economic. The strait is passed by ITF, i.e., a displacement water from the Pacific Ocean into the Indian Ocean caused by a difference in the sea water level. ITF flows across the Makassar Strait to south direction and passes through the smaller straits along Bali to Flores. ITF pattern is influenced by its local area condition which creates unique characteristics in each place. ITF passes through the Lombok Strait in part directly related to the Indian Ocean, as well as a very diverse state bathymetry of shallow ocean to ocean trenches. Various oceanographic phenomena affect ITF in the Lombok Strait: tides and waves are formed due to the interaction between the ocean currents from the Indian Ocean to the Lombok Strait, met with ITF flowing from the Lombok Strait into the Indian Ocean. As tides, currents are influenced by the tides that have harmonic components, but there are differences in the frequency and phase are formed. Harmonic component is one of indicators in determining the characteristics of a body of water. The purpose of this study is to obtain the derived harmonic components by analysing currents data in the Lombok Strait acquired from The International Nusantara Stratification and Transport (INSTANT) Expedition Mooring Deployment 1 conducted in 2004 to 2005. Based on the analysis it is known that the characteristic harmonic currents in the Lombok Strait is influenced by significant harmonic components such as Solar Semi Annual (SSA) and Solar Annual (SA)constituents be used, as the result of harmonic analyses of tidal data at ports all over the world reveal that they are dominated by the seasonal variations of sun.Keywords : ITF; Sea Current; Harmonic Component; INSTANT ExpeditionAbstrak. Selat Lombok merupakan salah satu alur lintas kepulauan Indonesia (ALKI) yang penting bagi perekonomian maritim nasional dan internasional, sekaligus sebagai alur dari arus lintas Indonesia (Arlindo). Arlindo merupakan peristiwa perpindahan masa air dari Samudera Pasifik menuju Samudera Hindia, yang disebabkan oleh perbedaan ketinggian air laut. Jalur Arlindo melintasi Selat Makasar menuju selatan, kemudian terbagi melewati selat-selat yang lebih kecil diperairan Bali hingga Nusa Tenggara Timur. Pola Arlindo dipengaruhi keadaan perairan setempat yang dilewatinya, sehingga Arlindo memiliki karakteristik yang unik pada masing-masing tempat. Pada Selat Lombok yang berhubungan langsung dengan Samudera Hindia,  fenomena oseanografi mempengaruhi ARLINDO di Selat Lombok diantaranya adalah pasang surut dan internal wave yang terbentuk karena interaksi antara arus laut dalam yang berasal dari Samudera Hindia menuju Selat Lombok. Arus pasut memiliki komponen harmonik seperti gaya pembangkitnya, namun terdapat perbedaan pada frekuensi dan fasa yang terbentuk. Komponen harmonik pasut dan arus pasut merupakan salah satu indikator dalam penentuan karakteristik suatu perairan. Tujuan dari penelitian ini adalah untuk memperoleh besaran komponen harmonik yang diturunkan dari arus di Selat Lombok dari Ekspedisi INSTANT Mooring Deployment 1 yang dilaksanakan pada tahun 2004 hingga 2005. Berdasarkan analisis harmonik diketahui bahwa karakteristik arus di Selat Lombok dipengaruhi oleh komponen harmonik signifikan seperti Solar Semi Annual dan Solar Annual yang merupakan komponen yang dipengaruhi oleh pergerakan matahari secara paruh tahun maupun tahunan.Kata kunci : Arlindo; Arus Laut; Komponen Harmonik; Ekspedisi INSTANT

Abstract. Yellowfin tuna (Thunnus albacores) is a large, pelagic, and migratory species of tuna that inhabits Moluccas Sea in Indonesia, and most sea environment worldwide. However, high fishing activities tend to happen in the Indonesia region and catch product appear to be decreasing. A better understanding of yellowfin tuna genetic diversity is required to plan better conservation strategy of tuna. The study was conducted to infer the genetic diversity of yellowfin tuna (T. albacores) in the Moluccas Sea. A total of 41 tissue samples of yellowfin tuna were collected from two regions in the Moluccas Sea (North Moluccas and Ambon) during an expedition in February 2013. The results showed that genetic diversity and nucleotide diversity of yellowfin tuna from North Moluccas population was 0.984 and 0.021, respectively; while in Ambon population, the genetic and nucleotide diversities were 1.00 and 0.018, respectively. The high genetic diversity (0.990) and nucleotide diversity (0.020) between two populations were observed. Based on phylogenetic analysis, no genetic differentiation between the two populations in Moluccas Sea was revealed .Keywords :  Population genetics; Haplotype diversity; Coral Triangle; Phylogenetics; Polymerase Chain Reactions (PCRs) Abstrak.

Abstract

Study related to plankton community in the Banda Sea and its adjacent sea has been conducted by several authors; However, t information on the relationships between of plankton abundance and catches volume of yellowfin tuna Thunnus albacares has been never been examined. Therefore, the objective of this study was to analyze the relationships between plankton abundance and catch volume of yellowfin tuna in Banda Sea Waters, Ambon. The result showed that the highest abundance of phytoplankton (59.259 cell/m3) was found at station 10, around Ambon, Seram and Haruku Island which located in the waters between many river runoffs. While, the highest abundance of zooplankton was 5,483 ind/m3, located around Ambelau Island. Both diversity (H') and evenness (E) index of phytoplankton were at the medium level, and there were no dominant species in this observation. Based on visual observation of remote sensing data, there was an indication of a relationship between the area with high concentration of chlorophyll-a (high phytoplankton biomass) with CPUE value of yellowfin tuna.Studi mengenai komunitas plankton di Laut Banda dan sekitarnya telah banyak dilakukan, akan tetapi telaah hubungan antara kelimpahan dan distribusi plankton dengan aspek perikanan belum banyak dibahas. Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara kelimpahan dan distribusi dari komunitas plankton dengan perikanan tuna di Perairan Kepulauan Banda. Kelimpahan fitoplankton tertinggi terdapat pada stasiun 10 yang terletak di daerah antara pulau Ambon, Seram dan Haruku (59.259 sel/m3) yang mempunyai akses ke muara-muara sungai di sekitarnya. Sedangkan kelimpahan zooplankton tertinggi terletak di sekitar Pulau Ambelau (stasiun 3), yakni 5.483 ind/m3. Tingkat indeks keanekaragaman (H’) fitoplankton sedang, indek keseragaman (E) rendah hingga sedang, dan tidak ditemukan jenis tertentu yang dominan. Berdasarkan pengamatan visual data penginderaan jauh memberikan indikasi adanya keterkaitan antara daerah dengan konsentrasi klorofil-a yang tinggi (biomassa fitoplankton tinggi) dengan hasil tangkapan per unit upaya penangkapan tuna madidihang.
