"ABSTRAKFisheries resources management aimed to improve community welfare especially fishermen and to conserve the fisheries resources and its environment, to keep the capture fisheries business system sustainability efficient and profitable. Beside marketing guarantee, optimalization between fisheries resources stock and fishing effort in each of fishing area. The improvement of capture fisheries must be held based on the existing condition, i.e.: marketing in determining the priority commodity, maximum sustainable yield and fisheries resources utilization level to determine limit of fisheries resources utilization chance, fishing technology and socio-economic condition to identify the fishermen's earns and absorption of labors related to capture fisheries sector. Based on the marketing aspect analysis, it is determined that the kinds of priority commodity in Southern of West Java Province are lobster, shrimp, tuna, skip jack tuna, and layar. Hence, the potency (MSY) and fisheries resources utilization level of the priority commodity still has very large chance to improve, except lobster has large enough chance. Based on the scoring approach, combined from many technical aspects, financial aspects and social aspect and linear goal programming analysis can be concluded that the proper fishing technology in southern waters of West Java Province are: (1) Purse seine 80 unit, (2) Denish same 127 unit, (3) Lines 144 unit, (4) Gillnet 80 unit, (5) Trammel net 376 unit."

"SURVEI KELAUTAN DI PERAIRAN SAMUDERA HINDIA SELATAN JAWA BARAT (PERAIRAN SELAT PANAITAN SELATAN). Telah dilakukan survei kelautan yang berhubungan dengan dispersi radionuklida di perairan laut Samudera Hindia. Penilitian dilakukan dengan cara mengambil sampel air laut untuk mengetahui konsentrasi 137Cs dan melakukan pengukuran CTD. Untuk mengetahui kondisi fisis oseanografi daerah penelitian, maka dilakukan pengambilan data temperatur, salinitas, dan densitas secara vertikal dengan menggunakan CTD di tiga titik pemantauan. Data hasil rekaman CTD dapat digunakan sebagai bahan untuk menganalisis pola arus yang terjadi di lokasi penelitian. Menggunakan software Ocean Data View (ODV), data CTD diolah dan ditampilkan dalam bentuk grafik terhadap kedalaman. Konsentrasi 137Cs di perairan Selat Panaitan – Selatan Garut dengan kisaran 0,14 – 0,30 mBq/L. Konsentrasi tersebut belum mengindikasikan dampak kecelakaan Fukushima walaupun pola arus global mampu mentranspor 137Cs dari sumber (Fukushima) ke perarain Indonesia. Arus yang berada di Samudera Pasifik masuk ke perairan Indonesia melalui sistem ARLINDO. Nilai konsentrasi terendah dan tertinggi terjadi karena perbedaan jarak stasiun penelitian dengan ARLINDO. Kata kunci: survei, samudra hindia, 137Cs ABSTRACT SURVEY OF MARINE IN SOUTH INDIAN OCEAN – EAST JAVA (STRAIT OF SOUTH PANAITAN).
