Penelitian ini menginvestigasi struktur kecepatan S di Lautan Hindia melalui fitting seismogram, akibat gempa C081499A, Sumatra Selatan dan direkam di stasiun RER, Pulau Reunion, Perancis. seismogram observasi dibandingkan dengan seismogram sintetik dalam domain waktu dan ketiga komponen kartesian secara simultan. Seismogram sintetik dihitung dengan program GEMINI, dimana input awalnya adalah model bumi global Ocean dan PREMAN. Selain itu pada kedua seismogram dikenakan low-pass filter dengan frekuensi corner pada 20 mHz. Analisis seismogram menunjukkan penyimpangan yang sangat kuat pada pengamatan atas waktu tiba, jumlah osilasi dan tinggi amplitudo, pada gelombang permukaan Love dan Rayleigh dan gelombang ruang S. Untuk menyelesaikan simpangan yang dijumpai diperlukan koreksi atas struktur bumi meliputi ketebalan kulit bumi, gradien kecepatan βh dan besar koefisien-koefisien untuk βh dan βv di upper mantle, dan sedikit perubahan pada kecepatan S di lapisan-lapisan bumi hingga kedalaman 400 km. Fitting seismogram diperoleh dengan baik pada waveform fase gelombang, baik waktu tempuh osilasi utama dan jumlah osilasi. Hasil riset ini menunjukkan, bahwa daerah Lautan Hindia mempunyai koreksi atas struktur kecepatan S dengan nilai positif terhadap model lautan. Hasil ini berbeda dengan hasil riset seismologi lainnya.

The research investigated the S speed of earth structure under Indian Ocean using seismogram fitting, due to the C081499A earthquake, South Sumatra and recorded in the observation station RER at Reunion Island, France. The observed seismogram is compared to its synthetic in time domain and three cartension components simultaneously. Synthetic seismogram is calculated with the GEMINI program, the initial inputs are the global earth models of Ocean and PREMAN. Prior to seismogram comparison, a low-pass filter with corner frequency of 20 mHz is imposed. The result of analysis shows a very strong deviation at the arrival time, oscillation amount and amplitude height of Love and Rayleigh surface waves and S body wave. To overcome the found discrepancies a correction to the earth structure is needed covering the earth crust thickness, speed gradient of βh and zero-order coefficient for the βh and βv in upper mantle, and a little change in S speed in earth layers down to a depth of 400 km. Seismogram fitting is better obtained at waveform of the wave phase, either the travel time or oscillation number of S wave and Love surface wave. The results shows that the Indian Ocean has correction to the S speed structure, which is positive to standard earth model. This result differs from other seismology research.

ABSTRACT
Indian Oceaon is influenced by the monsoon cycle. Monsoon cycle that occurs in the Indian Ocean influences the current patterns. Since a very strong westerlies occurs in The Tropical Convergence Zone TCZ at the equator, wyrtji jet is formed in the 40o 80o W lndian Ocean on a transitional season. Its branchs are possibly formed when the western coast of Sumatra which eventually creates South java Current SJC. SJC flows southeastward during December until April and northwestward during June until October, when it is associated with coastal upwelling. SJC develop upwelling on a seasonal basis.

Ikan tuna segar dalam klasifikasi produk hasil perikanan adalah ikan tuna yang didinginkan dengan suhu dibawah 0 ° C sampai - 2,5 ° C selama kurang lebih 14 (empat belas hari) dari penangkapan ikan di laut sampai ke konsumen. Sedangkan jenis ikan tuna yang dapat diolah menjadi ikan tuna segar adalah ikan mandidihang (yellowfin tuna), ikan mata besar (bigeye tuna) dan ikan tuna sirip biru (bluefin tuna). Kegiatan penangkapan ikan tuna di Perairan Samudera Hindia semakin meningkat dan mengakibatkan semakin luas dan jauhnya daerah operasi penangkapan di laut, terutama di perairan bagian barat yang daerah operasi penangkapannya sampai ke perairan sebelah selatan Negara India. Situasi ini mengakibatkan waktu operasinya .semakin lama dan ukuran kapal ikan juga semakin besar, sebagaimana kapal ikan long iner yang berpangkalan di Jakarta dengan ukuran 60 - 100 GT dan 100 - 200 GT dibandingkan di Benoa-Bali dengan ukuran 30 - 60 GT, 60 - 100 GT dan 100 - 200 GT. Penentuan pelabuhan pangkalan bagi perusahaan perikanan tuna segar ini mengakibatkan perbedaan besamya biaya kegiatan perusahaan dan pada akhimya akan mempengaruhi pendapatan perusahaan. Sedangkan untuk optimasi pendapatan perusahaan perikanan tuna segar melalui penentuan pelabuhan pangkalan tersebut dengan menggunakan Metoda Perbandingan Eksponensial yang hasilnya sebagai berikut : - Untuk pelabuhan pangkalan di Jakarta dengan menggunakan kapal ikan long liner yang berukuran 100 - 200 GT. - Untuk pelabuhan pangkalan di Benoa-Bali dengan menggunakan kapal ikan long liner yang berukuran 100 - 200 GT. - Untuk Perairan Samudera Hindia dengan menggunakan kapal ikan long-liner yang berukuran 100 - 200 GT dan dengan pelabuhan pangkalan di Jakarta. Di dalam penentuan pelabuhan pangkaian juga diperhatikan negara-negara yang terlibat di dalam pemanfaatannya karena masing-masing negara akan mengutamakan kepentingan nasionalnya. Sehubungan jumlah negara yang terlibat dalam pemanfaatan ikan tuna di perairan bagian Timur lebih sedikit dibandingkan di perairan bagian Barest, maka untuk mengoptimasikan pendapatan perusahaan dapat dipilih di Perairan Samudera Hindia bagian timur dengan kapal ikan long liner berukuran 100 - 200 GT dan dengan pelabuhan pangkalan di Benoa-Bali.

This research is cunducted to understand seasonal variation of surface current circulation over the Indian Ocean. The method used in this research was discriptive analysis. The data used were the seasonal surface wind direction and velocity from Ocean Surface Current Analysis Real - Time - National Oceanic and Atmospheric Administration (OSCAR - NOAA). The result showed that the seasonal variation of surface current circulation is influeced by movement of wind. During west season the north equatorial current is formed. during west season, the first transition season and east season is formed eddy current at western of Sumatera Island.

The archaeology of Atlantic slavery has been widely studied in recent years, but less attention has been paid to the post-slavery system of indenture that transported contract labourers from South Asia, China and Africa to new lands. Colonial Mauritius has left abundant archaeological remains, not least the cemetery for slaves and freed slaves established at Le Morne in the nineteenth century. Analysis of aDNA has demonstrated that individuals buried at Le Morne were of Madagascan and East African (probably Mozambican) origin, testifying to the long-distance movement of slave labour.

Coupled ocean-atmosphere mode in the tropical Indian Ocean, so-called the Indian Ocean Dipole (IOD), occurred during boreal summer to fall 2011. In this study, data from satellite observations and atmospheric reanalysis datasets together with data from ocean current mooring were used to evaluate the evolution of the 2011 IOD event. It is shown that the 2011 IOD was a weak and short-lived event. It developed in July, peaked in September, decayed in October and terminated in November. During the peak phase, maximum negative sea surface temperature anomaly off Sumatera- Java reached -1.2 °C. As oceanic response to easterly wind anomalies along the equator, the observed zonal currents in the central and eastern equatorial Indian Ocean also showed prominent westward currents during the peak phase of the 2011 IOD event.

Mode Kopel Laut-Atmosfer di Daerah Tropis Samudera Hindia selama Tahun 2011. Mode kopel laut-atmosfer di kawasan tropis Samudera Hindia yang dikenal sebagai fenomena Indian Ocean Dipole (IOD) terjadi pada musim panas hingga musim gugur tahun 2011. Pada studi ini, data observasi satelit, data reanalisis, dan data dari hasil pengukuran arus laut digunakan untuk mengevaluasi terjadinya fenomena IOD di tahun 2011. Hasil studi menunjukkan bahwa fenomena IOD tahun 2011 merupakan jenis IOD yang lemah dan berdurasi pendek. IOD di tahun 2011 mulai terbentuk di bulan Juli, mencapai puncaknya di bulan September, meluruh di bulan Oktober dan menghilang di bulan November. Pada saat fase puncak, anomali suhu permukaan laut di dekat pantai Sumatera-Jawa mencapai -1,2 °C. Data observasi arus di tengah dan di sisi timur ekuator Samudera Hindia menunjukkan adanya respon laut terhadap anomali sirkulasi atmosfer. Hasil pengukuran menunjukkan bahwa arus zona bergerak ke arah barat sebagai respon terhadap angin timuran pada fase puncak IOD tahun 2011.

The early history of nautical technology in the western Indian Ocean and adjoining parts of the eastern Africa coast is poorly understood. In the absence of evidence from shipwrecks, it has hitherto been based largely on the uncertain interpretation of a few documentary references and speculation surrounding technological parallels and assumed lexical resemblances. This paper examines some of the linguistic evidence in a more rigorous way, by undertaking a cross-dialectal comparison of names for watercraft and terms for outriggers in Swahili (Kiswahili), a Bantu language spoken on the islands and in scattered communities along the western seaboard of the Indian Ocean. The resulting analysis provides a new outline of the development of Swahili nautical technology and maritime culture, highlighting the key role played by particular boat forms, and the relative importance of indigenous innovation and different external influences, including the elusive impacts of Austronesian seafaring.
